SECTION 2: SAFETY ADVICE

2-2

GENERAL REQUIREMENTS

• Observation of safety regulations and also road traffic regulations ensures the safety of the driver, other users and the tractor.

• Carefully read the Operator's Manual before starting the tractor, because insufficient knowledge may endanger the operator and the equipment.

• The tractor shall be operated by a driver having the appropriate driving licence and knowledge of the principles of correct operation and use of tractors and agricultural machinery (implements).

• PRONAR P5 tractors are equipped with safer KS-10 cab suitable for carrying passengers on public roads. Do not carry a passenger on public roads.

SAFE TRACTOR OPERATION

• Before beginning work make a visual inspection of the tractor, its mounting and towing appliances, linked machines ( implements) and do not begin work without assuring yourself of full and correct linkage.

• Always apply secure connection to towed machines (original towing pin and its safety protection).

• Regulate the three-point linkage, so that the machine (implement) mounted on it in transport position is

rigidly connected with the tractor.

• Perform all servicing of the tractor and its equipment with utmost care, and especially the braking and steering systems, so that they are always in excellent technical condition, because they are vital to your safety.

• All actions connected with cleaning and washing, preparing for work and technical servicing are performed when the engine is not running and the tractor's handbrake is engaged.

• The cooling system is under pressure while the engine is running (there is a pressure valve in the radiator cap). Therefore do not unscrew the radiator cap while the engine is running, and when unscrewing it do so very slowly and carefully, to gradually lower the pressure in the system.

• When draining of hot liquid from the cooling system, or oil from the driving system assemblies and steering system apply particular care to avoid danger of scalding.

• Do not approach the tractor with an open flame (even a burning cigarette) when refuelling, servicing the fuel system and inspecting batteries.

• Do not make any modifications, and not mount parts and assemblies, which modify the tractor's structure without consulting the tractor's manufacturer.

SAFE TRACTOR WORK

• Before starting the engine or work with the tractor install all protective guards.

• Before starting the engine check that all steering controls (levers, hand wheels and switches) are in

neutral position. This way you prevent accidental movement of the tractor and connected machines.

• Do not start the engine and do not operate control levers (pedals) unless you are seated in the driver's seat.

• Before moving from place release handbrake and make sure that any persons assisting in service or linking machinery are not in danger, especially that they are not between tractor and linked machine (implement). Warn them of intention to move, using the horn.

• Children must be kept away from tractor and agricultural machinery.

• Do not dismount from the tractor if it is in motion.

• Before leaving the cab stop the engine and engage handbrake.

• Do not work with the tractor in closed rooms without intensive and efficiently operating ventilation, because

inhaling the exhaust fumes can be fatal.

• If the engine or the steering system is operating incorrectly while driving, stop the tractor, because the tractor in such a situation requires significant strength applied to the steering wheel in order to steer it.

• DO NOT work and do not allow your helpers to work under machines (implements) that are raised by tractor linkage.

• Do not leave machines (implements) raised by the tractor linkage, while tractor is idle for long periods.

• In the event that the wheels of the tractor front axle loose contact with the ground after raising a machine

(implement) attached to the three-point linkage, apply weights to front axle. If the tractor front axle in spite of this does not obtain stable contact with the ground (enabling free manoeuvring of the tractor and implement combination) DO NOT work with that machine or implement.

• Make sure that before raising or lowering three-point linkage mounted machines (implements) and also before turning that there is no risk of collision with people or objects or any other danger.

• DO NOT work with PTO shaft, which drive machines and implements from the tractor PTO, without guard covers.

SECTION 2: SAFETY ADVICE

2-3

• While checking (while parked) linked machines (implements) driven by tractor PTO disconnect PTO drive.

• In the event of using supplementary or assisting assemblies make certain that they are compatible with the

tractor. Familiarise yourself with the principles of their correct mounting and operation with the tractor.

ATTENTION: In the event of using a fore end loader observe the maximum permissible front axle loading and also recommended (permissible) speed. Counterweights should also be applied to the rear linkage system. The fore end loader must not be used without a counterweight suspended from rear three-point linkage.

DANGER: If you use the tractor incorrectly, it may be dangerous to you, other persons and the surroundings. Do not work with equipment not designated to work in combination with the tractor!

DRIVING THE TRACTOR

To avoid dangerous situations (especially where tractor is at risk of overturning) be careful and pay attention when driving the tractor. Adjust speed to the surface conditions, especially when moving across uneven (hilly) terrain, when passing ditches, on slopes and at corners (turning points). Do not make sharp turns at full loading and high tractor speeds.

SAFETY RULES WHEN UNDERTAKING TRANSPORT WORK

While travelling along roads - also private roads, always observe traffic regulations in force in the country where the tractor is travelling.

• When driving on public roads, the tractor shall be equipped with a reflective warning triangle, and on the tractor shall be mounted a triangular plate distinguishing slow- moving vehicles. In the event that the tractor is moving linked to a trailer or machine, the triangular distinguishing plate shall be mounted on the trailer or machine (according to regulations).

• Do not drive the tractor (with trailer, machine or implement) without effective braking and signalling light installations in vehicle assembly or with installations of trailer (machine) not connected with tractor. This could lead to an accident.

• Do not leave trailers (machines and implements) on public roads disconnected from tractor. In the event of malfunction, drive onto verge, position warning reflective triangle (tractor and trailer optional equipment) in a manner according to the regulations and turn on parking lights.

• Do not leave the tractor (tractor implement combination) on slope. In the event of the necessity to leave implements, engage 1st gear, engage front axle drive (setting „engaged ”) and parking brakes.

• Do not exceed permissible speeds arising from the traffic code of the country of use (20 mph in the UK). Do not drive on slopes with engine switched off, gear and travel direction lever of tractor in neutral position („disengaged”) or with depressed clutch pedal. This could lead to an accident.

• Do not carry people on trailers and machines (implements). It is forbidden!

• Take care that independent brake pedals are connected and operate simultaneously.

• Do not drive the tractor with a trailer if red indicator light is on signalling insufficient pressure in trailer

(trailers) braking. It may prevent effective braking.

• Only connect trailers and machines (implements) to tractor in the manner envisaged by the tractor manufacturer i.e. using original drawbar pins with safety catches (cotter pins). Other connection methods may pose danger.

• Do not work with trailers, of a total weight greater than 3 500 kg, without brakes.

• While towing the tractor, the traffic code shall be observed at all times. Tractor towing is permitted with an

engine switched off, effective steering system and with a speed not exceeding 6 mph.

SECTION 2: SAFETY ADVICE

2-4

TRACTOR WORK WITH POWER TAKEOFF SHAFT (PTO) ENGAGED

• In the event of necessity to inspect the machine (its disconnection) during work with machines (implements) driven by the PTO, ensure that PTO does not rotate before leaving cab.

• While working with machines (implements) driven by PTO persons being in the vicinity of rotating assemblies or machine elements must not wear loose clothing, because it might pose danger.

• While working with stationary machines, driven by PTO, always engage parking brake, block front and rear wheels and position front wheels for driving straight ahead.

• Do not wash, regulate or service machines (implements) driven by PTO when engine is running.

• Always use covering guard, and when PTO is not used, place protective covering over end of PTO shaft.

• Do not use shafts to drive machines without the complete guards envisaged in tractor design.

• Always apply the appropriately selected PTO shafts (depending on the driven machine's torque that needs

to be transferred). Torque value in Nm is normally given on guard of PTO.

FIRE SAFETY RULES

• Do not add, for any reason, petrol or mixtures to the diesel fuel because this may significantly increase the danger of fire or explosion.

• Always screw the fuel cap tightly onto fuel tank inlet.

• Do not pour fuel while engine is running.

• Do not smoke cigarettes while pouring fuel and also while servicing fuel system.

• Do not fill the total capacity of fuel tank. Always leave a small space for fuel expansion.

• Always refuel after finishing work to reduce water vapour condensation occurring overnight in fuel tank.

• Do not store fuel and lubricant materials within the distance less than 3 m from the permanent parking

place of tractor. Equip the place with reliably operating fire extinguishing equipment.

• Be careful during repairs involving welding. Clean place of repair so that no fire may occur during work.

• Ensure the air-tightness of the exhaust system so that it cannot be contaminated, especially from the

exterior with flammable substances.

• Do not allow the occurrence of leaks from fuel and hydraulic systems.

• Equip tractor with GP-1X, BC-DB, or similar type of extinguishers and secure them

in fasteners.

SAFETY RULES FOR WORK ON SLOPES

In order to prevent air from entering the fuel system during work on slopes and undulating fields, the quantity of fuel in the tank should always be a minimum of 1/4 fuel tank capacity. If possible avoid driving tractor across the slopes (required directions - upwards and to bottom of field). If work shall take place across slope, one should additionally:

• use the widest wheel spacing,

• make turns in an upwards direction,

• do not lift implements higher than necessary in order to make the manoeuvre (e.g. turn),

• check that tyre pressure in rear wheels is uniform,

• the travel speed at turns to the minimum,

• while using a reversible plough begin ploughing from the top of the elevation summit; thus the wheels on

the upwards side travel in the furrow trough - reducing the angle of inclination of the tractor.

DRIVER'S SEAT

In PRONAR P5 tractors four types of drivers seat may be installed, assuring good working

conditions, enabling adjustment and adaptation to the weight of the driver, his dimensions and individual requirements.

Before starting work with tractor make adjustments to seat adjustment so that the position is

the most comfortable for you. All seat adjustment is done while sitting on it.

IMPORTANT! Seat adjustment system elements (bolts, nuts, rollers and guides) should be

cleaned and greased with a long lasting grease every 1000 mth but no less frequently than once a year.

a) PRONAR MT50/M60 seat

Adjustment according to weight of driver operator (50÷120kg) made by articulated

handle 4 placed in lower part of shock absorber system by changing springs tension. Lengthways movement (in range ±75 mm ) made by disengaging lever 3 teeth under seat cushion. After setting position, release lever block, which ensures maintaining set position. Back support inclination angle (in range 2°÷16°) is adjusted smoothly with the aid of knob 1. Seat height is adjusted smoothly (in range ±30mm) by turning knob 2. Inclination angle of armrests is set with the aid of knobs 5 placed in armrests.

Figure 4-17 Location of adjustment controls of PRONAR MT50/M60 type seat.

b) TOP S-698 (MOL 698) SEAT

SEAT seat may be adjusted and suited to weight and measurements of operator. Adjust shock absorption with knob 1 depending on weight of operator in range 50120kg.

Lever 2 places seat in level plane. In order to adjust pull the lever 2 sideways and then lock the required position by releasing lever.

Knob 3 adjusts the height of the seat in range of 60 mm.

VENTILATION, HEATING AND CAB AIR CONDITIONING SYSTEM

Figure 4-22 Ventilation, heating and cab air conditioning system. 1 – switch for air draft inlet speed control from outlets in cab upper panel; 2 – switch controlling inlet

temperature of cold air from outlets in cab upper panel (option – air conditioning); 3 - guides (adjustable) of air outlets in cab a panel upper panel; 4 - guides (adjustable) there are outlets by steering column; 5 – switch setting inlet temperature of hot air from outlets by steering column, 6 - switch controlling speed of air from outlets by steering column.

System enables ventilation and heating cab in low temperatures, or cooling (air conditioning) cab at higher temperatures with the aid of guides in forward cab console.

A) CAB VENTILATION AND HEATING: Connecting fan blower

Connecting blower takes place by connecting fan with knob 1 located in upper cab panel and 6 (Figure 4-22) placed to the right of the steering column. Knob connecting fan serves as fan speed regulator, controlling volume of air output.

Connecting heater and adjustment of temperature.

Heater knob 5 (Figure 4-22) enables smooth temperature adjustment of hot air from heater. Turning heater knob to the right or left side lowers or increases temperature of air coming from heater to air outlet.

ATTENTION! It is not recommended to apply water in engine cooling and cab heating system. Antifreeze liquid should be applied. Engine cooling and heating system in PRONAR tractors are filled with "BORYGO ECO” coolant liquid .

ATTENTION: If the engine cooling and heating system is filled with water, then at lower ambient temperatures it should be removed from the engine cylinder block and radiator and from cab heater.

B) AIR CONDITIONING OF CAB: Connecting air conditioning

Air conditioning only works if:

- vehicle engine operates driving air-conditioning compressor,

- thermostat is connected, and temperature setting allows connection of compressor clutch,

Section 4: STEERING AND OPERATING CONTROLS

4-17

- fan blower is connected pushing air through evaporator,

Connecting fan blower

Blower can be switched on by connecting fan with knob 1 (Figure 4-22) placed on control panel 1 on the left side of cab. Knob connecting fan serves as fan speed regulator, controlling volume of air output.

ATTENTION: IN ORDER FOR AIR CONDITIONING FAN TO WORK IT MUST BE SWITCHED ON! Activating thermostat and temperature adjustment.

Thermostat knob 2 (Figure 4-22) enables smooth adjustment of temperature of cooling air. Turning thermostat knob to the right or left reduces or increases temperature of air leaving evaporator. Thermostat controls operation of electromagnetic clutch of air conditioning compressor. It is to prevent frosting of the evaporator. Disconnection of compressor clutch should take place at temperature 5°C to 6°C measured on evaporator in external temperature of 20°C and medium engine revs.

ATTENTION: IN ORDER FOR AIR CONDITIONING TO WORK AIR CONDITIONER MUST BE SWITCHED ON!

It is recommended to close all doors and windows in cab while air conditioning operates in order to assure optimum efficiency. It is recommended that internal air temperature of cab is not reduced below 5 °C in relation to external temperature.

Ventilation

- fan knob 1 (Figure 4-22) selects required degree of blower operation,

- by setting outlet guides directing air to required place,

Cooling

- fan knob 1 (Figure 4-22) selects required degree of blower operation,

- thermostat knob 2 (Figure 4-22) sets required temperature, Remember that an inflow of fresh but not cooled air raises the air temperature inside the vehicle.

ATTENTION! In the event of high air humidity one should avoid simultaneously setting minimum temperature and RPM of fan blower. This may cause frosting of evaporator, which is felt due to reduction of air output. In this case one must deactivate air conditioning for 2-3 minutes and set maximum fan output.

Air conditioning servicing

Regularly with frequency depending on usage conditions clean condenser (blow through with compressed air). At each vehicle service check:

- silent running of electromagnetic compressor clutch,

- tension and condition of v-belt driving compressor,

- the level of filling with working agent (cooling effectiveness). In the autumn and winter season air-conditioner should be regularly operated for about 10 min (once a month or more often). This is intended to prevent drying of seals of compressor shaft. It also prevents the development of bacteria and fungus on the external surfaces of evaporator sides. Before the summer season the action of air conditioner's individual components and the tightness of system should be checked.

ATTENTION: Air-conditioner components include filter-dryer, whose main function is absorbing moisture in the system. Moisture in combination with R134a agent creates an aggressive chemical compound causing corrosion of metal elements of the air-conditioning system. Filter-dryer MUST be changed at least every two years, most preferably, annually. Before changing the filter, remove the cooling agent from the system, and after filter changing, refill the system. Neglecting to change the filter leads to lasting damage to some components of the air-conditioning system, which may require very expensive repairs.

Section 4: STEERING AND OPERATING CONTROLS

Damage to the cooling agent circulation

In the event of damage (leaks, unreliability of valves etc.) refer to an authorised service for assistance. Do not release working agent into the atmosphere!

ATTENTION: The closed-circuit air-conditioning system is filled with R134a cooling agent under pressure. The user must not release cooling agent from the system. In the event of damage (leaks, unreliability of valves etc.) refer to an authorised service for assistance. Do not release working agent into the atmosphere!

Section 4: STEERING AND OPERATING CONTROLS

STEERING SYSTEM

PRONAR P5 type tractors are equipped with a hydrostatic steering system with Danfoss, Rexroth or WPA dosing pumps allowing steering of the tractor when the engine is not running. The system is equipped with a hydraulic pump (permanently engaged) driven by the tractor engine. It is possible to change the inclination angle of the steering wheel and the setting along the steering column axis to the most comfortable position for the operator.

To change the inclination angle use the pull rod 1 (Figure 4-23) pulling towards yourself and hold. To change the position of the steering wheel setting, release pull rod and lock it with small movements. The angle change mechanism has 4 positions (in a range of angle settings), in which the steering wheel is locked. One may choose one of these 4 settings in the range from 25° to 40° every 5°.

Figure 4-23 Steering column inclination lock pull rod.

Change setting of steering wheel along axis requires (Figure 4-24):

• loosening steering wheel axis cover and the screw 1;

• setting steering wheel in chosen setting in the adjustment range of 100

mm;

• tightening the cover with screw 1 (manually).

Figure 4-24 Change steering wheel setting along its axis. 1 – steering wheel axis cover together with a screw

BRAKES

Working brake (basic)

During road travel brake pedals should be locked with the catch (Figure 4-25)

During fieldwork, if necessity arises of making small radius turns one may brake after unlocking the catch, the left or the right wheel, by pressing the appropriate pedal. One should brake smoothly, without jerks, pressing the pedal to the end and not holding it in intermediate positions. Do not rest feet on pedals unnecessarily. This leads to an accelerated wear on brake disk abrasive linings.

Figure 4-25 Catch locking working brake pedals.

ATTENTION: Before road travel the working (foot) brake pedal catch must be locked.

Parking brake (emergency)

The parking brake is installed on the left side of the seat. It immobilises the tractor while parking.

Do NOT use parking brake to stop the tractor in motion. An exception is an emergency situation, when while travelling, the working (basic) brake is ineffective or is damaged without any prior fault symptoms. The parking brake is operated by pulling lever upwards. To release brake lever pull slightly upwards then press the button 1 located at the end of the lever and push it down completely. (Figure 4-26)

FRONT AXLE DRIVE

Drive should be engaged:

- when the necessity arises to overcome temporary resistance on paved roads and hard subsoils,

- in fieldwork with bad soil traction properties (very damp, covered with plant remains, loose soil etc.),

- in fieldwork if the machine (implement) combination requires great traction force,

- in use of the front axle for braking the tractor.

Figure 4-27 Front axle drive connector may be set in two positions:

1 - drive disengaged (upper); 2 - drive engaged (lower).

ATTENTION: Do not engage drive during travel on a paved roads.

Do not use engaged front axle drive at speeds above 15 km/h or turning front wheels more than 30.°°°°

In the event of necessity to use front wheel drive during travel in reverse gear, drive should be applied briefly (position2, Figure 4-27).

ATTENTION: During use of tractor with foreloader observe the above instructions and limitations contained in loader Operator's Manual. Failure to observe instructions may cause damage to elements of front axle drive system.

Section 4: STEERING AND OPERATING CONTROLS

DIFFERENTIAL LOCK MECHANISM

DANGER:

Do not engage differential lock mechanism at speeds above 10 km/h

and at corners - it may hinder driving the tractor.

Figure 4-28 Rear axle differential lock

mechanism control (located on switch panel on the right side of the seat)

Differential lock mechanism switch (Figure 4-28)– has two positions: 1 (upper) – lock disengaged - the tractor may move in road transport on paved roads and in field conditions with good soil adhesion. 2 (lower) – lock engaged (permanently) - while in fieldwork or transport in situations when driving wheels slip and the tractor is at risk of being bogged down.

ATTENTION ! Differential lock mechanism may be engaged during fieldwork and transport during increased wheel slip.

ATTENTION: Engaging differential lock mechanism on paved surface AND WHEN TURNINGTHE FRONT WHEELS MORE THAN 18 degrees°°°° is FORBIDDEN

ATTENTION: Failure to observe the above principles reduces the period of faultless operation of the drive system and hinders driving the tractor. Lock engaged (setting 2 lower key button on Figure 4-28) for brief use - in order to overcome road impediments.

Section 4: STEERING AND OPERATING CONTROLS

4-22

REAR POWER TAKE-OFF SHAFT (PTO)

PTO of PRONAR tractors may drive hitched cooperating machines with revolution speeds:

- independently (of travel speed), standardised: 540/1000 or 420/750 rpm

- dependent (on travel speed). Number of revolutions per metre of road is fixed, independently of

which gear is engaged.

ATTENTION: Before connecting machine powered with PTO one must check that the PTO rotation speed of the tractor corresponds to the required speed of the machine shaft.

ENGAGING PTO DRIVE

ATTENTION: To eliminate dynamic loading in PTO drive transfer system before engaging PTO shaft drive, reduce engine RPM to 900 rpm. After engaging PTO drive, increase RPM required level. Before disengaging PTO drive also reduce engine RPM. It is particularly important in combination with machines with a great moment of inertia. Such machines should be equipped with a one-way clutch.

Failure to comply with the above instructions may lead to accelerated wear of PTO drive transfer system components and, as a consequence, increase the frequency of necessary maintenance adjustment or part replacement.

In PRONAR tractors, the PTO drive is connected with the switch placed on the console on the

right side of the seat (Figure 4-29) or outside the tractor with button placed on the rear right mudguard

(Figure 4-30).

ATTENTION: The operation of engaging and disengaging PTO is conducted only with the engine running.

In order to engage PTO, first press the black button in the middle of the yellow mushroom switch,

and next pull the yellow part upwards (as shown on pictogram).

In order to disengage PTO press PTO switch to the base.

ATTENTION: Before raising machines (implements) suspended on three-point linkage, driven by the tractor's PTO, or making turns, disengage the PTO drive.

ATTENTION: AT SHUTTING DOWN THE ENGINE - PTO DISENGAGES AUTOMATICALLY

PTO switch placed externally on the left mudguard serves only for momentary connection of PTO

(e.g. in joining up machines).

ATTENTION: Operator may only use external PTO switch standing to the side of the tractor. To avoid damaging machine or tractor do not use simultaneously control system in the cab and outside the tractor.

To start rear PTO using a button on mudguard it is necessary first to press the black button in the PTO switch 1

(Figure 4-29

) placed in cab (only press the button without pulling the yellow mushroom part upward). Next press and hold the green button on the mudguard (Figure 4-30). PTO shaft shall rotate while operator holds the button.

DANGER: Before using the external PTO switch, make certain that there is nobody and nothing near the machine or PTO shaft. Never engage PTO standing:

- directly behind the tractor or wheel

- between lower link arms

- on machine or beside it. When engaging PTO, never put hand or leg or any other part of the body close to threepoint linkage, PTO or machine.

SELECTION OF DEPENDENT-INDEPENDENT PTO ROTATION

Choice of type of dependent-independent rotations shall be made with disengaged PTO drive.

Figure 4-31 PTO control lever (switchover to

MOVING OFF

ATTENTION: Before starting work with tractor check the operation of engine, steering system, brakes and remaining tractor systems and assemblies.

The engine should run evenly in the whole revolution speed range. Control elements, steering system, brakes, lighting and signalling systems, screen wipers should be checked and be in good technical condition.

When moving off perform the following actions:

• depress clutch pedal fully (fig. E-6);

• release previously engaged handbrake;

Figure 5-5 Clutch pedal.

• set reducer lever 1 (fig. E-7) depending on requirements in setting:

L – slow "field" gears; H - fast "road" gears.

ATTENTION: Changing gear groups "field - road” should

take place only when tractor is completely stationary.

• gear selection lever according to diagram 1 (fig. E-8) engage selected gear.

• gear should be engaged with smooth movement, do not jerk lever. If gear is not immediately engaged,

then with an equally flowing movement place in neutral, release pressure on clutch pedal lightly and then press to resistance and engage gear. Proceed in the same manner when operating reducer and gear group selection lever;

• smoothly press „accelerator”(increasing engine revs) slowly, also with fluid movement release pressure on clutch pedal;

• after releasing pressure on clutch pedal remove foot from pedal;

• Further gear changing should be while travelling after pressing clutch pedal to resistance, with the

exception of reverse gears (do not engage reverse gears if the tractor is moving forward)

ATTENTION: It is recommended during transport work, for which a trailer with large capacity (and

weight) is used, to start moving in low gears in gear group selection position 1, and after moving tractor-trailer combination, make switch to gear group position 2. Proceed using the same method changing gears upwards, until the appropriate, safe driving speed is reached.

Crawling gears reducer (option)

Apart from "field-road" reducer PRONAR P5 type tractors may be equipped with crawling gears reducer (available option), which is engaged by lever 1 (fig. E-9) located on the floor. Crawling gears are engaged placing lever in position marked with "snail" symbol.

Figure 5-8. Lever 1 of crawling gears reducer (option).

"Powershift” torque booster

Gearbox with "Powershift” torque booster enables one step reduction of all speeds, through which traction power is increased. Change of setting takes place with the aid of switch located in gear lever (Figure E-10) without the use of clutch pedal, also during work of tractor under load. Working mode is signalled by the"tortoise” or "hare” lamp on indicator panel.

- "Powershift” in position "hare” – disengaged

STOPPING ENGINE AND TRACTOR

Stopping tractor requires:

• reduction of engine RPM speed;

• pressing on clutch pedal until resistance is felt;

• setting gear lever in neutral setting (N);

• pressing working brake (primary);

• after stopping tractor, engaging parking brake hand lever (Figure 5-2).

ATTENTION: In the event of emergency braking, simultaneously press brake and clutch pedals.

Do not stop engine at high temperatures of lubricating oil and coolant liquid. It is recommended to leave engine running at lower revolution speeds until oil and coolant temperature drops. Stopping engine requires setting the accelerator lever 2 (Figure 4-16) in "minimum" position”, and turning the ignition key to position 0 (Figure 4-15) and in the event of finishing work, disconnecting battery with switch inside cab (Figure 5-2). Indicator lamps on control panel should be extinguished.

ATTENTION: Turbocharged engines (PRONAR-5130 / 5135 / 5235) must be allowed to cool down after work, if they operated under load. Before stopping the engine, first reduce engine revolution speed to 800-1000 rpm and allow to run idle without load for around 5 minutes.

REAR THREE-POINT LINKAGE

DESIGN

PRONAR tractors are equipped with rear three-point linkage

implement lift system whose attachment dimensions correspond to category 2 lift according to ISO-730 standard. Rear lift enables the coupling of mounted and semi-mounted implements to the tractor. Their action is operated through the hydraulic system.

The lower link connecting arms are raised and lowered with the aid of hanging rods connected to the hydraulic lift arms. They are equipped with open end jaws, enabling quick coupling and uncoupling of implements. The hanging rods are easily regulated, to facilitate correct setting of implements in relation to tractor.

The top link arm is attached to the bracket on the central housing of the rear axle. Rear part of top link shall be attached to upper hitching pin of the attached implement. Top link arm is also adjustable, to facilitate setting implements.

Figure 5-10 Three-point linkage suspension – components. 1 – lower link connecting arms; 2 – stabilisers; 3 – hanging rods; 4 – top link arm;

LINKAGE OF MACHINES (IMPLEMENTS)

Machines (implements) mounted are attached (linked) with the tractor at three points: by two ball joints of

lower arms and above, by top link.

To attach the equipment, adjust hanging rods and ensure that stabilisers are mounted and correctly

adjusted. Dismantle the agricultural hitch if it is an obstruction.

DANGER: Before proceeding to link machines or equipment engage parking brake.

Linking

The majority of implements may be linked to the tractor in the following manner:

1. Set the tractor so that the hitching points of the lower arms are levelled and slightly in front in relation to the pins of the implement to be hitched.

2. Slide ball coupling sleeves onto pins enabling attachment and implement to lower arms of tractor.

1 2

3. Attach implement to lower arms. Ensure that the self locking catches 2 on each of the lower arms protrude from the housing as shown on Figure 5-11. If not then pull grip ring 1 and the catch will jump outwards. Slowly raise the lower arms upwards until self locking catches 2 link to ball joints; you will hear the snap.

Figure 5-11 Jaw ends of lower arms. 1 – grip ring; 2 – catch;

Section 5: USING THE TRACTOR

5-9

DANGER:

1. If external controls switches on mudguards are used for attaching lower arms, engine must run. For making other connections stop the engine.

2. Before using the external three-point linkage attachment control make sure that there is no person or object near the implement or three-point linkage.

3. Never operate external switches while standing:

- directly behind the tractor or wheels

- between lower link arms

- on implement or beside it

- never use the help of an assistant, operating second set of switches on the opposite mudguard or control panel inside cab

- while approaching switch set on opposite mudguard go around the tractor or the implement.

- do not pass between implement and tractor.

4. With tractor immobile and parking braking engaged the adjust top link, so that pin of implement bracket may pass through bracket and top link..

5. Connect external hydraulics, if applicable.

6. After attaching implement and before beginning work check that the implement does not interfere with any part of the tractor.

ATTENTION: During linkage of mounted and semi-mounted implements to three-point linkage or to transport or agricultural hitch make sure that the appropriate distance is maintained between implement and tractor (cab, rear screen, tyres) in each implement position. Regulate telescopic stabilisers, if needed.

To disconnect machine (implement) from three-point linkage:

1. lower implement onto ground ensuring that it shall not fall after disconnection from tractor;

2. disconnect top link of three-point linkage pull release grip releasing 1 (Figure 5-11) on right and left lower arm

4. completely lower arms and drive tractor forward away from implement During disconnection adhere to the following precautions:

- always leave implement on a hard level surface

- support implement in such a way that it shall not fall over on disconnection from tractor

- always reduce pressure in three-point linkage cylinders by selecting loose setting before disconnection.

ADJUSTMENTS

During linking implements to three-point linkage it is possible to make the following adjustments:

Hanging rods

Adjustments of hanging rods are made by rotating upper part of hanging rod with the aid of grip 1 (Figure 5-12) on internal threaded shaft. Before shaft can be turned, lift it in order to disconnect catch 2, located on lower section of hanging rod. Next, turn threaded shaft to lengthen or shorten the hanging rod assembly. After adjustment, release threaded shaft so that it is locked preventing its accidental turning.

Figure 5-12 Three-point linkage hanging rod.1- threaded shaft together with grip; 2- locking catch.

Section 5: USING THE TRACTOR

5-10

ATTENTION: When regulating hanging rods, ensure by extending hanging rods that they do not separate and that the threaded shaft is sufficiently overlapped by the sleeve in order to withstand working load. Maximum unscrewing is signalled by two thread windings on hanging rod ends.

Three-point linkage hanging rods equally have two options of mounting them to the lower arms (Figure

5-13):

1. two round openings if lower arm and its ball joint cannot change position in relation to hanging rod. This connection is applied at work for automatic adjustment.

2. and to opening of elongated shape. Then it is possible to change the setting of lower arm in relation to hanging rod. This enables mutual compensation for movements of tractor and machine (implement), especially of large working width, in plane of transverse direction of tractor travel.

Figure 5-13 Means of attaching hanging rods to lower arms. A - three-point linkage hanging rod mounted in round opening; B - three-point linkage hanging rod mounted in elongated opening.

ATTENTION: After change of place of securing hanging rods, pins of lower arms securing hanging rods should be secured with original securing linch pins.

Top link

The design of the top link (internally threaded sleeve engaging threaded shafts) enables its shortening or

extension (by rotation of central part 1 (Figure 5-14), as required. After regulating top link, prevent autonomous change of length by tightening counter nut 2.

Figure 5-14 adjustment of three-point linkage top link.

ATTENTION: When regulating top link, ensure that the ends are extended in equal lengths and locked by locking nut 2. Also ensure that extension of the top link does not cause its separation into several parts and that the threaded shafts shall be sufficiently screwed into the threaded central sleeve in order to bear working load. Maximum unscrewing is signalled by two thread windings on link ends.

If the top link is not used, it may be dismounted or left in a vertical position secured in holder.

Telescopic stabilisers

Telescopic stabilisers regulate swinging on the lower arms and attached equipment during work and

transport. It is of major significance during work on slopes and along fencing or ditches and in the use of some implements.

Each telescopic stabiliser is composed of a sleeve 1 (Figure 5-15) with articulated joints at each end

2 and 4. The ball ending joint 2 is screwed into the end of the sleeve, enabling adjustment and is attached to the securing bracket 3, bolted to the rear axle housing. The spade terminal 4 is attached to the lower link 5 of the three-point linkage system. This end is free and may slide inside the sleeve. The assembly may be locked, by locking catch 6 through opening C in sleeve and pin.

2 1 4 3

Figure 5-15 Three-point linkage

lower arm stabilisers. 1- sleeve; 2ball ending; 3- securing bracket; 4spade terminal; 5- lower link; 6locking catch

In practice, locking catch 6 should be taken out of both stabilisers, and the implement attached to the

three-point linkage. In order to take out locking catch pulling the snap fastening backwards. When the implement is appropriately set, rotate sleeve until openings in sleeve corresponds with openings of free spade terminals. Lock locking catch through opening C and secure with snap fastening.

With such a setting the stabilisers are locked as a rigid assembly and the implement is secured

against swinging equally during work as in transport.

In certain conditions or during work with such implements as ploughs etc, allowing sideways

movement of three-point linkage and implements may be indicated.

If locking catches 6 are taken out and set in oval opening B in the middle of the sleeve1, movement

shall be possible sideways to a limited angle or to opening A (pin shall act as a block, limiting angle of swing).

ATTENTION: When setting the length of the stabilisers, especially in positions allowing swaying, ensure that there is no possibility of contact between tyres and stabilisers or lower arms.

For example if tractor is working with plough, make the following three-point linkage adjustment:

• during ploughing the tractor (normally) has the right wheels in the furrow, level the plough frame (shortening or elongated right hanging rod), because in relation to the field surface, the tractor is tilted to the right side;

• so that the depth of work of the first and the last plough body shall be the same it is necessary (after levelling) change the length of the top link using turning lever 1 (Figure 5-14) after unscrewing locking nut 2. After adjustment tighten locking nut.

During travel of tractor with suspended machine (implement) for greater clearance (under the machine) one may shorten top link.

CONTROL OF LIFT WITH THE AID OF THE EHR ELECTRO-HYDRAULIC SYSTEM

IN PRONAR P5 TRACTORS

PRONAR P5 type tractors enable control of lift depending on a group agrotechnical requirements,

soil condition (cultivations), properties and technical parameters of linked machines (implements) with the aid of the EHR electrohydraulic system. The EHR system enables the tractor operator to increase travel speed and concentrate on the appropriate movement across the ploughed field, simultaneously freeing him from the necessity of continually monitoring the working equipment. It enables significant acceleration of fieldwork and simultaneously increases the degree of work precision, and benefits e.g. with seed material.

An electronic regulator available in various models permits implementation of the following regulating programs:

• adjustment of power, position and mixture of rear and/or front mounted implements system. Electronic regulator analyses signals from power and position sensors;

Figure 5-18 Means of adjustment applied in agricultural tractor hydraulic lifts.

• lengthways vibration suppression (rocking) of tractor. Tractor with heavy

plough mounted during transport travel has a very poor weight distribution, easily resulting in the development of vibration. By appropriate programming in the electronic regulator, with control of the hydraulic ram cylinder, it is possible to ensure very good suppression of this vibration.

Figure 5-19 Vibration suppression graph.

Control of the rear three point lift with the electro-hydraulic system is with the aid of the control pulpit (Figure 5-20) located on the right side of the seat and additional arm lift and lower buttons on the rear of the mudguards on right and left sides of tractor (Figure 5-20, item 10) (they are used during linking machines and agricultural implements).

Control of the rear three-point linkage implement linkage is as follows:

• - using setting knob 4 (Figure 5-20) - depending on the type of fieldwork, determine the means of implement adjustment (position, power or mixture);

• with setting knob 2 set working depth of implement, and using setting knob 3 set the lift height in transport setting;

• lowering the implement is performed by placing lever 1 in lower setting (indicator light illuminates 8

After lowering implement and its penetration into the soil, conduct additional adjustment of optimum

working conditions of the implement:

• using knob 4 - means of adjustment;

• using knob 5 - speed of depth correction or working height;

• using knob 2 - set working depth of implement.

ATTENTION: In the event of intensive heating of the adjustment system, place knob 4 in position

adjustment and knob 5 towards the "tortoise” position.

In the event of temporary emergence of plough from heavy soil increase plough depth by pressing lever 1 to lower setting. After releasing lever 1 return it to the "lowering” position set earlier, and the plough to the depth set with the knob 4.

ATTENTION: Do NOT use tractor in the event of hydraulic pump malfunction, if the light 8 (Figure 5-20) is not extinguished after lifting implement.

Apart from the above described functions, EHR system has the function of suppressing vibration

during transport of implements. To engage vibration suppression system:

• lever 1 (Figure 5-20) set in "lifting” position (then implement is raised to the extreme upper setting) and button 6 to lock implement in transport position;

• press button 7 for vibration suppression (implement is lowered about 3% downwards from extreme upper setting).

ATTENTION: Vibration suppression function acts only by setting of lever 1 (Figure 5-20) in "lifting” setting in transport position with button 6. During fieldwork (ploughing, cultivation etc.) vibration suppression function should be switched off.

Section 5: USING THE TRACTOR

EXTERNAL HYDRAULIC SYSTEM

PRONAR tractors have an external hydraulic system enabling operation with double-acting and single-acting

hydraulic cylinders and with continuous flow hydraulic fittings. The system is equipped with three (fouroption) pairs of external hydraulic outlets equipped with quick couplers at the rear of the tractor and one pair of quick couplers at the front of the tractor on the left side beside the fuel tank.

ATTENTION: The pair of quick couplers at the front works simultaneously with the first pair of quick couplers at the rear of the tractor, i.e. in the event of using the quick couplers at the front of the tractor, the pressure increases equally in the first pair at the rear of the tractor. DO NOT use both pairs simultaneously.

All quick couplers are controlled by levers placed inside the tractor cab on the right side of the driver's seat. By each of the levers there is a pictogram with lever setting symbols.

Enables free movement of cylinder in both directions due to which equipment such as i.e. snow plough is able to follow the surface of the road.

Working setting of control lever with snap fastening enables holding lever in a given position. Locations of

snap fastening on individual control levers are shown on pictograms in the form of a symbol (Figure 5-21).

DANGER: Use the lever controlling a pair of quick couplers to work with loader in snap fastening position may cause uncontrolled movement and as a result cause damage to loader or pose danger to the operator.

First pair of quick couplers A-A1 (Figure 5-22) regulates oil stream flow with the aid of selector knob 1 (Figure 5-23). On the knob is a scale from 0 to 9. To increase turn knob so that greater values are visible on scale. If after turning knob lower value shall be visible, then flow concentration is reduced.

Figure 5-23 Flow regulation knob 1 and valves 2 applying single or double action.

Connecting hydraulic conduits check that they are clean. Connecting dirty conduits causes the

hydraulic system tank of your tractor to be contaminated, which may (despite filters installed) cause malfunction of the tractor's hydraulic system (pump, distributor etc).

ATTENTION: Ensure that oil in cylinders is clean and of the appropriate grade.

Connecting single acting cylinders

In connecting single acting cylinders (e.g. trailer) to quick coupler supply sockets A, B or C then adjust valve 2 (Figure 5-23) to single acting. To do this loosen securing nut, and then using screwdriver screw out valve 2 placed below quick coupler to which single acting cylinder shall be connected and again secure tightening securing nut. Then returning quick coupler is directly connected to drain tank. Then raise cover and plug in single acting cylinder conduit to supplying quick coupler ensuring that it is properly seated. Check of the conduits have enough slack enabling turning the tractor or implement in both directions. Start control lever, to supply oil under pressure to complete the process of engaging tractor and implement hydraulics.

Section 5: USING THE TRACTOR

5-18

In order to extend single-acting cylinder pull the lever controlling quick coupler to rear in "lifting” setting. In order to stop the cylinder before it is completely extended move lever to neutral setting.

To retract a single acting cylinder push control lever forward in "lowering" setting. ATTENTION: Do not keep lever in "lifting” or "lowering” setting if external cylinder has reached the end of its

stroke, because this causes "impact" to transfer valve. Compression of oil by transfer valve causes heating of oil, which may lead to a hydraulic system assembly malfunction.

ATTENTION: Single acting cylinder may equally be controlled by external hydraulic quick coupler adapted to double action. However remember back to retract cylinder one must use "floating" setting. To choose setting, move control lever beyond the "lowering" setting.

Connecting double acting cylinders

In the event of connecting double acting cylinders to quick coupler pairs A-A1, B-B1 or C-C1 then one must adapt valve 2 (Figure 5-23) to double action. To do this loosen securing nut, and then using screwdriver screw out valve 2 placed below quick coupler pair to which single acting cylinder shall be connected and again secure tightening securing nut. Then raise cover and plug in conduit supplying double action cylinder to upper supplying quick coupler, and return conduit plug to lower socket of quick coupler of pair set for double sided action, ensuring that it is properly seated. Check the conduits have enough slack enabling turning the tractor or implement in both directions. Start control lever, to supply oil under pressure to complete the process of engaging tractor and implement hydraulics.

ATTENTION: Before proceeding to work check that movement of hydraulically powered machine assembly corresponds to movement of lever. In the event that it does not, swap conduits on pair of quick couplers.

In order to extend double-acting cylinder pull the lever controlling quick coupler to rear in "lifting” setting. In order to retract double-acting cylinder push the control lever forward, beyond neutral setting in "lower” position. Moving the lever forward beyond the "lower” setting selects floating setting, which enables free movement of cylinder in either direction and is suitable while working with such equipment as a snowplough or loader.

ATTENTION: Snap fastener holds lever in selected setting "lifting” or "lowering”. In order to stop the cylinder before it is completely extended move lever to neutral setting. Lever does not return automatically from "floating" setting.

ATTENTION: Do not keep lever in "lifting” or "lowering” setting if external cylinder has reached the end of its stroke, because this causes "impact" to transfer valve. Compression of oil by transfer valve causes heating of oil, which may lead to a hydraulic system assembly malfunction.

Connecting hydraulic continuous flow accessories

When connecting continuous flow hydraulic optional equipment (e.g. hydraulic motors), connect supply conduit to the lower quick coupler A1 of the first pair of quick couplers equipped with flow regulation valve, and a return to D "free drain” quick coupler (Figure 5-22). This enables direct return of oil to tractor hydraulic system. Quick coupler A1 should be adapted to double action using valve 2 (Figure 5-22) as in the case of double acting cylinders. Flow regulation valve enables smooth regulation of through flow intensity or revolution speed of hydraulic motor with the aid of selection knob 1 (Figure 5-23).

For hydraulic motor to operate it is necessary for control lever to be moved into "lowering” setting. To stop motor move lever forward from "lowering" setting into "floating" setting. The motor then slows down

until it stops. Never choose "neutral" or "lifting" setting during work of motor, because this will cause rapid stopping and increase the pressure in hydraulic circuit.

Section 5: USING THE TRACTOR

5-19

ATTENTION: Before proceeding to work, check that hydraulic motor rotates after setting control lever in "lowering" setting. In the event that it does not, swap conduits.

In order to ensure optimum cooling and prevent oil heating, operate continuous flow equipment by setting flow rate using knob 1 (Figure 5-23) at maximum and lowest revolution speed of tractor engine, which ensures the required performance of machine and appropriate speed.

Disconnection of hydraulic conduits from quick couplers

To disconnect hydraulic conduit grasp it with one hand at a short distance from the coupler and with second hand grasp coupler then quickly pull conduit. To disconnect or to connect quick coupler, reduce pressure in hydraulic system. To do this before starting the motor, move control lever into "floating" position. This causes pressure drop. Disconnect motor with control levers in "floating" setting. After stopping motor, set levers in neutral position. Now quick coupler may be connected and disconnected at minimum pressure with little effort.

DANGER: Before disconnecting motors or implement, make sure that the equipment or implement is supported in a safe manner.

PNEUMATIC TRAILER BRAKING SYSTEM

The combined trailer pneumatic braking system (double and single conduit) is composed of engine driven compressor, air tank, control valves and three pneumatic connectors. Connectors are mounted at rear of tractor and may be connected to single conduit or double conduit trailer braking system. Pneumatic connectors are in three colours: black, red and yellow. Black connector is used for single conduit system, and red (supply) and yellow (control) for double conduit system.

ATTENTION: Various types of trailer braking systems are available. Before connecting to tractor's pneumatic braking system, read trailer manufacturer's Operator's Manual.

Figure 5-24 Pneumatic system connector. A- yellow connector (double conduit system) B- red connector (double conduit system) C- black connector (single conduit system)

ATTENTION: Trailer brakes only act when they are pressed by both brake pedals in tractor. Therefore brakes should always be locked together with catch, if a trailer is hitched to tractor.

Tractor handbrake is connected to the main control valve. After connecting handbrake, trailer brakes are activated.

Single conduit trailer system

If the trailer is equipped with single conduit system then connect pneumatic conduit to black

connector C (Figure 5-24) of tractor's pneumatic system. After releasing tractor's brake pedals and parking handbrake, 0.62 MPa pressure is maintained in the connection. Activating tractor brakes causes drop in pressure proportional to pressure applied to brake pedals and activation of trailer brakes.

Double conduit trailer system

In trailer with double conduit braking system, connect pneumatic system supply conduit to red

connector B (Figure 5-24), and control conduit to yellow connector A (Figure 5-24).

ATTENTION: Double conduit system only works after connecting both conduits to red and yellow connectors.

Supply conduit (red) – is the conduit that fills the tank of the trailer's pneumatic system. If for some reason

the trailer braking system is disconnected from the tractor, the pressure falls to 0 and trailer brakes are applied.

Section 5: USING THE TRACTOR

5-21

Control conduit (yellow) – after connection of tractor brakes, increased air pressure is supplied through yellow connector to trailer's control valve until there is full pressure in system. Degree of trailer braking is proportional to pressure applied to tractor's brake pedals.

After starting engine, release handbrake and brake pedals. Pressure drop indicator light of pneumatic system on the control panel next to the air pressure indicator (item 6; figure 4-12) will be illuminated until pressure in pneumatic system rises to about 0.5 Mpa. After reaching required pressure of

0.55÷0.8 Mpa on air pressure indicator, loud sound of releasing excess air to atmosphere through valve will be heard. Press brake pedal several times to be sure that pressure shown on the gauge falls after engaging brakes and rises after releasing them.

DANGER: Never drive the tractor when trailer brake light is illuminated.

ATTENTION: Before connecting conduits, clean trailer and tractor connectors. Ensure that connections are secured. Check trailer brakes regularly to make sure they operate correctly.

DANGER: Do not overuse brakes on steep slope. Use the same gear as when going upwards, for descending slope of the same steepness.

HYDRAULIC TRAILER BRAKING SYSTEM

Trailer hydraulic brakes may be connected to hydraulic system through quick coupler 1 (Figure 5-25) placed to the rear of tractor just under the yellow connector of pneumatic system.

Figure 5-25. Trailer hydraulic braking system

connectors. 1- hydraulic couplers (red)

After connecting brake conduit of trailer coupler, they shall be automatically engaged after pressing

foot brake pedals in tractor. Pressure in brake conduit shall be proportional to the force of pressure on brake pedal and amount to max. 150 bar.

Main brake pedals must always be locked together with catch, to ensure correct action of trailer

brakes.

In the event of not using hydraulic coupler to brake trailer, it should be covered with anti-dust cover.

ATTENTION: With engine switched off, hydraulic pressure may not be transferred to trailer braking system. When parking tractor-trailer assembly engage tractor and trailer hand brake with working engine.

Therefore brakes should always be locked together with catch, if a trailer braking system is connected to tractor.

CHANGE OF FRONT AND REAR DRIVE AXLE TRACK

Front and rear axles of PRONAR P5 type tractor enable alterations of wheels spacing setting

depending on the method of setting wheel disc in relation to hub and wheel tyre and through mutual exchange of wheels (left to the right side), right to the left) and change of tyres.

Possibility of setting discs according to wheel tyres is shown in Figure 5-26:

A (A’), C (C’) – internal reinforce; B (B’), D (D’) – external reinforcement; C, D – transfer of wheels; A’, B’, C’, D’ – rotation of discs

Figure 5-26 Method of securing tyres in relation to wheel discs.

Depending on the size of tyres with which the tractor is equipped the following axle track settings are

possible:

Table 5-1 Axle track range in PRONAR P5 type tractors

Tyres Front axle track Rear axle track

380/70R24 1559-1859 mm 360/70R24 1559-1859 mm 420/65R24 1559-1859 mm -

11.2R42 - 1528-1784 mm

When changing axle track setting, if change to the other side is necessary, then dismount wheel from tractor, turn by 180° and mount on opposite si de of tractor. Direction of arrows on side of tyres should be according to forward direction of travel of tractor. Projections of tyre tread are then set properly and tyre (wheel and tractor) and may ensure maximum traction in given conditions.

DANGER: Tractor wheels are very heavy. Proceed with them very carefully and secure wheels against falling over during dismounting and causing injury. Due to the associated risk, dismounting rear wheel from tractor requires two people, unless the person changing the wheel has at his disposal auxiliary appliances (lifting crane, overhead crane, forklift etc).

After changing and mounting wheels tighten bolts securing wheel disc to hub with torque of:

- front wheel:280 Nm

- rear wheel : 380 Nm

and also bolts securing wheel disc to tyre ring with torque of 230±20 Nm

DANGER: Never drive tractor with loosened tyre ring or wheel disc. Always tighten nuts with the specified torque in the recommended time periods.

ATTENTION! After changing axle track it is essential to set convergence, which for wheels of the

front drive axle should be 0 ÷ 1 mm measured at distance of 330mm from the wheel centre.

ATTENTION: At narrower axle track settings, there may be interference between tyre or mudguard and tractor, if the wheels are in maximal turning position. In order to avoid these, adjust wheel turning limiters and mudguards limiters.

Section 5: USING THE TRACTOR

5-24

FRONT WHEEL TURNING ANGLE ADJUSTMENT

Tractor's front wheels are fitted with turning limiters 1. Limiters should be so regulated that they ensure a minimum of 20 mm space between tyres and whatever part of tractor in maximum turn position to the left or the right.

To adjust limiters 1 first loosen securing nut 2, and then tighten or loosen regulating screw 1 setting the required turning angle. After adjustment, tighten securing nut 2 using torque of 200 Nm.

After adjusting both turn limiters, ensure that the appropriate space is maintained at maximum turn of wheels between tyres and the tractor.

Figure 5-27 Front wheel turn angle adjustment.

Front wheels are equipped with moving front mudguards, which turn together with wheels when tractor turns. When angle turn increases, mudguard angle turn remains limited, to prevent collision of mudguard with engine bonnet, simultaneously allowing further turning of wheel under mudguard. Because of this there is a smaller turning radius than in the case of traditional mudguards. Initial and final point adjustment at which mudguards stops during turning the wheel on right or left side is made with the aid of adjustment bolts 3 and 4. With wheels set to drive forward is loosen securing nuts, and then screw in or screw out regulating bolt 3 set mud guard parallel to wheel and secure the securing nut. Then with wheels turned maximally to the right, adjustment bolt 4 shall be set out required turning angle limitation of right wheel mudguard in order that mudguard does not touch engine parts or engine bonnet.

After adjusting right mudguard, wheel should be turned maximally to the left and the left mudguard adjusted. After adjusting both turn limiters, ensure that the appropriate space is maintained at maximum turn of wheels between tyres and the tractor.

INCREASING THE TRACTION PROPERTIES OF PRONAR TRACTORS

PRONAR tractors can be fitted with a range of appliances and options for increasing traction, that is

increasing the pulling power of the tractor, reducing slip, and including increasing speed, which is synonymous with reducing fuel use per surface unit worked. Such appliances and such methods include:

• 4-wheel drive;

• three-point linkage hydraulic lift - the fact that equipment is mounted on a tractor increases the load on

the rear driving axle and reduces slip;

• use of automatic adjustment (especially depth adjustment on machine with working elements operating

submerged underground) equally increases load on rear drive axle;

• front axle weight - mainly causing improvement of stability, if a relatively heavy machine is mounted;

• possibility of filling front and rear tyres with liquid (water);

• rear axle differential lock (driver operated),

a) Weights

In PRONAR P5 tractors in order to additionally load front axle of tractor working with mounted machines of great weight it is permissible to mount 12 45 kg weights on tractor frame bracket or front three-point linkage (option) (Figure 5-29).

ATTENTION: Tractor shall not be used if securing rods 2 (Figure 5-29) and bolts 4 securing weights are not in place and properly tightened. Space between weights is not allowed.

Front weight should be mainly used to improve stability of tractor when operating three-point linkage machines of great weight (or moved far to the rear of the centre of gravity). In light work not requiring maximum traction, front weights should be dismounted.

ATTENTION: If tractor is moving at great speed over uneven terrain, forward loading does not always guarantee sufficient stability. In such conditions reduce speed and exercise caution. Weight bearing should be limited to the weight bearing capacity of tyres and tractor. Each tyre has recommended weight bearing capacity, which must not be exceeded.

Section 5: USING THE TRACTOR

5-27

b) Filling tyres with water or non-freezing solution. To increase traction tractor wheels may be filled with water or non-freezing solution (Figure 5-30).

ATTENTION: It is not recommended to fill front wheels with water or non-freezing solution, if it reduces tractor's steering ability.

Before filling wheels with water, raise the wheel and release air from inner tube, releasing tube valve and placing air inlet upwards. If you have a special valve of filling wheels with water, screw it to the valve. If you do not have such a valve, attach a rubber tube with water under pressure (e.g. connected to tap). Water flows into tyre tube until the moment of pressure equalisation then remove rubber tube and release compressed air from tyre tube. This action should be repeated several times until water overflow is from the tyre tube valve placed at the highest possible point. Next screw in valve insert and fill with air to required pressure. The amount of solution (water) in tyre tube should constitute 75% of its capacity volume.

Figure 5-30 Method of filling tube with water.

ATTENTION: Remove water from tyre tubes before temperatures drop below 0°C,

If increased traction is required during winter, tyres should be filled with solution of calcium chloride in proportion depending on external temperatures and tyre size.

DANGER: All solution preparation work shall be done in rubber gloves and with utmost care. To ensure safety when preparing the solution, pour calcium chloride into water and not the reverse.

c) Emptying liquid from tyres.

To remove liquid from tyre tubes:

- lift wheel and turn tyre with valve to the top

- release air from tyre tube and unscrew air valve, then turn wheel with valve downwards.

ATTENTION: LIQUID SQUIRTS OUT! ATTENTION: Before releasing liquid there may be pressure in tyre tube. Rotate a wheel several times so

that valve is at the top.

- remove remains of liquid by screwing on terminal for liquid filling and with the aid of compressed air, remove for as long as liquid continues to drain out.

- unscrew water filling terminal, screw in air valve and fill to required pressure

- after pumping air into valve, screw on valve cap

- proceed the same way with remaining tyre tubes.

ELECTRICAL SYSTEMS

ATTENTION: The tractor body is connected to negative polarity (-). Before connecting whatever receiver to electrical system, check polarity and connect appropriately.

Alternator

ATTENTION: Do not make repairs using an electric welder on tractor or machine connected with it without disconnecting the electrical systems (both lead cables) of alternator.

To ensure reliable operation of alternator when supplying

tractor's electrical systems, apply the following principles:

• Do no work on electrical systems with engine running and battery connected.

• Do not check electrical system element connections by „spark method” (short circuit);

• disconnect battery from „mass” while mounting or dismantling alternator.

• always check polarity before connecting battery to electrical system and also starting batteries (transport) used by some users for starting in low temperatures.

REFUELLING TRACTOR

PRONAR P5 type tractors have a fuel tank of capacity 155 litres located on left side of tractor

(Figure 5-39).

In order to fill fuel tank 1 it is necessary:

- to clean surface around inlet cap 2, to prevent dirt getting into tank and contaminating fuel

- remove the inlet cap and place it in a clean place during fuelling

- after filling tank, replace and screw on cap.

Figure 5-39 Fuel tank. 1 – fuel tank on tractor's left side; 2 – fuel inlet cap ATTENTION:

1. Lost or damages caps should always be replaced with original replacement cap

2. Never take off the cap or pour fuel with engine running.

3. Control filling nozzle while pouring fuel into tank.

4. Do not fill completely. Allow space for fuel expansion.

5. Immediately wipe away spilt fuel.

6. Do not smoke in the vicinity of diesel oil.

In order to remove sediment or drain fuel from tanks unscrew drain plug 1 (Figure 5-40) at the

bottom of the tank on the left side of the tractor.

Figure 5-40 Fuel drain plug. 1 – fuel tank drain plug. After removal of sediment of fuel from tank, screw in plug.

ATTENTION: Fuel tank drain plug should be tightened using a torque not exceeding 10 Nm. Otherwise there is a risk of shearing the thread causing fuel leak.

OPENING ENGINE BONNET

The bonnet is secured with hinges in front of front windscreen to ensure easy access to engine in

order to conduct periodic service. Two compressed gas springs placed under bonnet facilitate lifting.

Figure 5-41 Bonnet and engine side covers. 1 - engine bonnet; 2 - side cover; 3 - snap fasteners securing side cover; 4 - bonnet lock release pull rod

To raise the engine bonnet 1 (fig. E-35) proceed as follows:

• to pull release ring 4 to open bonnet catch;

• raise bonnet 1 upwards so it is held in position by compressed gas;

• if necessary remove side covers 2 pull out snap fastener 3 securing side covers on right and left side of

engine (if present);

To close engine bonnet lower it energetically. Bonnet catch should snap shut.

ATTENTION: In the event of high temperatures, engine side covers should be removed from tractors equipped with them.

WASHING TRACTOR

PRONAR 7150 tractors are modern machines with a large number of electrical sub-assemblies, which are sensitive to water. This should be remembered while washing tractor, especially when using highpressure washing equipment. Tractor may be washed with water with addition of commercially available car washing agents. Before washing, first protect battery, starter motor, alternator, exhaust pipe, air filter and sensors. During washing remove dirt from surface of tractor assemblies.

When washing with pressure washer jet do not stand too close to the tractor and avoid directing

stream of water at electronic or electrical subassemblies, electrical connections and air bleeders.

ATTENTION: Never direct stream of cold water on the hot engine or exhaust system.

Section 5: USING THE TRACTOR

5-34

RUNNING IN TRACTOR

ATTENTION: The first 50 mth of tractor work have a significant influence on tractor life and especially on the engine.

A new tractor, at the beginning of the working period should be run in for a period of not less than 50 hours. During running in time it is important:

• Not to allow engine overheating;

• Not to allow overloading of engine. Work in high gears under great load may cause overloading of

engine. This results in engine's unresponsiveness to increased RPM.

• Do not allow engine to work without load. It may have the same negative effect on engine as overloading. Change type of work undertaken so that engine is used in conditions of great and small loads.

• Carefully watch appliance indicators and controls;

• Stop work of tractor and contact service at whatever sign of incorrect operation of engine or tractor.

In addition to normal maintenance during the running in period also check every 10 hours the levels of liquids and oils in gearbox and rear axle, hydraulic systems, forward drive axle and engine. Check the tightness of bolts securing wheels to wheel hubs.

After the running in period, conduct service inspection after 50 hours (at manufacturer's authorised service) in the extent given in table "TABLE OF TECHNICAL SERVICE INSPECTIONS”. Method of performing all specified functions is described in Section 6 "MAINTENANCE”. Service inspection after running in is performed at purchaser's cost.

TOWING TRACTOR

For towing tractor use the towing drawbar pin in front weights. If possible, use towing shaft or chains to the tractor. In the event of using chain avoid sudden manoeuvres. Observe the local rules referring to towing.

DANGER: Do not use rope or string to tow the tractor In the event of breaking, rope or string may strike with sufficient force to cause physical injury.

ATTENTION: When towing the tractor, set all levers and gears to neutral position. Gear reduction lever should be in "HARE” position. Otherwise gear assembly may be damaged during towing.
