4. GENERAL DESCRIPTION OF DESIGN AND FUNCTION

The T703 trailer is a steel structure with the load body tipped to the sides and to the rear.
The trailer has a pneumatic service brake (with variable load braking force control) and a
parking brake that is hand-operated via a screw gear, actuating the friction components of the
axle service brake. The trailer features a complete signalling and warning system (an electrical
system and reective lights). The trailer is also suitable for transport on public roads.

The trailer is manufactured in accordance with Directive 98/37/EC and the following
harmonised standards: PN-EN 1853:2002, PN-EN ISO 4254-1:2006, PN-EN ISO 12100-1:2005,
PN-EN ISO 12100-2:2005, PN-EN 294:1994.

4.1. Chassis

The trailer chassis is composed of the following subassemblies: bottom frame, tow bar,
support foot, wheel set and fastening components.

The bottom frame and the tow bar are welded structures made of steel sheet and proles.

The trailer wheel set is composed of: a single axle, land wheels and land wheel brakes.

The axle is made of a square bar terminated with plugs on which land wheel hubs are set by
cone bearings. They are single wheels equipped with drum brakes with the jaws actuated by
mechanical expander cams.

Operating instructions. T703 farming trailer 15

4.2. Load body

The loading space of the trailer is made of the following:

The top frame (box frame) that is set on the bottom frame (chassis frame) in articulated seats
secured by pins which serve as pivots during tilting (tipping) of the top frame (load body/box).

The side walls/boards and their top sections are singular components. Each component
features a separate set of locks for closing and opening of individual wall and top sections
independent of each other and in any order. These design solutions increase functionality and
facilitate operation of the trailer.

The wall and top section locks are secured against accidental release.

4.3. Load body hydraulic tipping mechanism

The hydraulic mechanism is designed for automatic unloading of the trailer by tipping the
load body backwards or sideways. The hydraulic tipping system is fed with oil from the tractor
hydraulic system.

The hydraulic system includes: the coupling valve plug, hydraulic lines, the single-action
hydraulic actuator, the cut-off valve, and connecting and fastening components. Figure 1 shows
the diagram of the load body hydraulic tipping system. The lifting and lowering of the load
body is controlled by the DCV in the tractor's hydraulic system.

INFORMATION! * The cut-off valve limits the load body tilt angle during tipping to

the sides. The valve is pre-adjusted by the trailer manufacturer. Do
not adjust it on your own.

4.5. Support foot

The T703 trailer is equipped with a mechanically operated support foot. It is designed to
support the tow bar when the trailer is decoupled from the tractor. The foot is installed at the
tow bar beam fork.

INFORMATION! Do not rest the trailer on the support feet when it is loaded.

4.6. Braking system

The T703 trailer is equipped with the following braking systems:

• Service brake: pneumatically actuated two-line system, operates the axle wheels; controlled

from the driver's seat by pressing the tractor's brake lever;

• Parking brake: hand mechanical control via a crank lever mechanism and a screw gear,

located on the right side of the trailer and operating the axle wheels.

• The service brake design ensures automatic braking of all trailer land wheels if the pneumatic

system is accidentally decoupled between the trailer and the tractor. On customer's request,

the trailer can be alternately equipped with a single-line braking system (i.e. for adaptation

to tractors which support such system conguration).

6. OPER ATION INFORM ATION

6.1. Commissioning the trailer

IMPORTANT! • Use only tractors that are t for service (with the transport hitch,

pneumatic and hydraulic systems, and the signalling/warning
system working)

Do the following before commissioning the trailer:

- Understand the names and locations of individual assemblies/components of the trailer;

- Check the tyre pressure;

- Couple the trailer with the tractor:

• set the tow bar hitch-ring of the trailer on the trailer transport hitch height;

• couple the hitch-ring with the trailer hitch;

• secure the hitch pin against falling out;

• turn off the tractor's engine;

• engage the tractor's parking brake;

• release the trailer's parking brake;

• connect the appropriate sockets and plugs of the following systems: pneumatic, hydraulic
and electrical;

- Do the functional checks of the electrical, pneumatic and hydraulic systems of the tractor
and of the trailer, and check leak tightness of the hydraulic and pneumatic systems on both
vehicles;

- Check all equipment, their connections and safety from accidental release or breaking.
Do all these actions each time you start the trailer.

INFORMATION! Couple the trailer with the tractor's transport hitch only that is rated

for 11.5 KN of minimum load. No bystanders shall remain between
the trailer and the tractor when the two are being coupled.

INFORMATION! Two persons and extreme caution are required to install and remove

the top sections.

6.2. Loading the body

Load the body only when the trailer is coupled with the tractor, parked on level ground and

with the tow bar in the forward driving direction.

Use mechanical loading equipment (cranes, loaders, conveyors, etc.) to load the trailer.
Make sure that all wall and top section locks are engaged before loading the trailer.
Spread the load evenly across the entire load body surface. When transporting materials

that exert focused (topical) pressure on the load body (e.g. large rocks), line the oor with thick
planks rst. This will reduce the surface load of the oor and protect it from damage.

When transporting large volume materials, install the top sections of the load body walls. If

the transported materials protrude from the trailer, follow the applicable trafc code regulations
for proper marking of protruding loads.

Operating instructions. T703 farming trailer 19

INFORMATION! • Do not exceed the permissible payload and permissible axle loads,

otherwise the trailer can be damaged and the trafc safety can

be compromised.

• The transported load must be secured from shifting, generating

excessive noise and falling down on the road.

6.3. Travelling on public roads

Before entering a public road, do the actions listed in section 6.1 and the following:

- install the slow-moving vehicle sign on the trailer (in the bracket on the rear wall);

- ensure that the transported load is secured from shifting and falling down on the road;

- check that the load does not exceed the permissible capacity or multiple axle load.

INFORMATION!

• Follow the trafc code regulations.

• In the rst operating hours of the brakes, the drum brake shoes

align themselves to the drums. The full braking effectiveness is
achieved once the friction parts have run in.

6.4. Unloading

The load body can be unloaded manually, with mechanical equipment or by tipping the box

with the hydraulic mechanism.

Unload by tipping the load body by following these actions in the order presented below:

• align the tractor in the trailer's axis;

• engage the tractor's parking brake;

• remove the safety pin that couples the load body with the chassis frame:
a) unloading to the back – move the pin to the rear;
b) unloading to the left – remove the right safety pin and install it on the left side;
c) unloading to the right – remove the left safety pin and install it on the right side;

• make sure that the pins on the side to which the trailer is to be unloaded have been properly
installed;

• open the body wall locks on the unloaded side;

• tip the load body by operating the hydraulic actuator;

• after the load has been discharged, lower the body and lock the wall(s) with the locks.

Operating instructions. T703 farming trailer 20

INFORMATION! • If it is necessary to unload the trailer on a slope, it is allowed

to tip the trailer body upwards (with the tractor and the trailer
parked in the uphill direction).

• Nobody is allowed to remain near the tipped trailer body and

within the range of discharged load.

• Do not decouple the trailer from the tractor when the load body

is lifted.

• Before unloading by tipping the trailer load body, you must

always verify that the pins have been removed on the correct side
of the trailer. Failure to remove the pins may destroy the trailer!

• Do not transport any persons on the trailer.

Open the top lock of the load body by moving the handle up, and depressing the button

under the handle at the same time. Open the bottom locks of wall segments by operating the

- install and secure the pins that connect the load body with the chassis frame;

- lock and secure the wall(s) from accidental opening.

6.5. Decoupling from the tractor

Do the following actions to decouple the trailer from the tractor:

• stop the tractor with the trailer where the latter will be left, and engage the tractor parking
brake;

• engage the trailer parking brake;

• if the trailer stands on uneven or sloping ground, protect it against rolling down by chocking
the wheels;

• disconnect the electrical, hydraulic and pneumatic lines from the tractor;

• remove the safety from the hitch pin and then remove the pin – this will decouple the tow bar
from the hitch. Drive away with the tractor and reinstall the pin in the hitch.

Operating instructions. T703 farming trailer 21

INFORMATION!

Do not decouple the trailer from the tractor when:

• the load body is lifted;

• the trailer is not protected against rolling away.

7. SERV ICING

7.1. Servicing instruction for adjustable trailer components

In order to maintain proper performance, the T703 trailer requires the following adjustments:
a) Adjustment of the wheel bearing clearance;
b) Adjustment of the braking system components.
c) Adjustment of the load body hydraulic tipping mechanism.

INFORMATION! • Do not perform any checks or servicing under the loaded or tilted

load body without support.

Wheels – bearing slackness adjustment

During the rst operating hours of a newly purchased trailer (i.e. after approximately 100

km of mileage) and further operation (i.e. after the next 1500 or 2000 km), check the wheel
bearing clearance and adjust if necessary.

To do so, it is required to:

• Couple the trailer to the tractor and engage the tractor parking brake.

• Jack up one side of the trailer to lift the wheel from the ground on this side and secure it
against falling.

• If the wheel has excessive clearance, remove the hub cap and remove the crown nut clevis
pin.

• Rotate the wheel and tighten the crown nut at the same time until the wheel stops turning.

• Loosen the crown nut by 1/6 to 1/3 of the full turn, i.e. until the nearest clevis pin groove is
aligned with the hub pivot hole.

• Secure the nut with a new clevis pin, and reinstall and retighten the hub cap.
After a correct adjustment of bearing clearance, the wheel should rotate smoothly, without

cogging or evident resistance (not caused by rubbing of the brake shoes against the drum).
Slight friction of brake shoes against the drum, especially on a brand new trailer or following
replacement of the shoes is normal. Do the nal check of proper bearing adjustment by travelling
several kilometres and inspecting the hub heating by hand. Apart from incorrect slackness
adjustment, signicant rolling resistance of the wheels and excessive heating of the hubs can
also be caused by contaminants in the grease or damage of bearings. If found, these symptoms
require removing the wheel hub to be corrected.

INFORMATION!

Operating instructions. T703 farming trailer 22

• Follow these rules when jacking up the trailer wheel:

• couple the trailer with the tractor, move to level ground and

engage the tractor parking brake;

• chock the wheel that is not being jacked up;

• place the jack under the axis and near the jacked up wheel,

and lift the wheel so that it clears the ground;

• secure the wheel against falling by putting a prop of suitable

height under the axis.

7.2. Brakes

7.2.1. Brakes – servicing the brake pneumatic system

When servicing the trailer, check the tightness and the condition of parts and connections of

the braking system, and periodically drain the water condensate from the air tank.

Check the leak tight ness of the system at the rated pressure of approx. 600 kPa for the single -

line system and 800 kPa for the two-line system. Leaks are detected by a distinct hiss or air
bubbles (after coating with soap water) at the points of air escape from the system. If the leaks
are caused by damaged seals, lines or other parts (valves, actuators, etc.), replace them with new
parts.

Drain the water from the air tank by tilting the drain valve stem to the side when the tank is

pressurised; the drain valve must also be unscrewed from the tank and cleaned of accumulated
dirt once a year, before the winter season.

7.2.2. Brakes – adjustment of the braking system components

When servicing the trailer, check the condition of parts and connections of the braking

system, and periodically inspect the lubrication of control elements.

Adjust the brakes when the following occurs:

• there is excessive clearance between the shoes and the drum from the brake shoe wear,
resulting in decreased braking performance;

• the wheel brakes work unevenly and out of sync.
With the properly adjusted brakes, the braking force (i.e. the total of braking forces at the

circumference of the wheels) shall be at least 27% of the permissible total weight of the trailer
when decelerating with the service brake; the braking force (i.e. the total of braking forces at
the circumference of the wheels) when actuating the parking brake shall be at least 16% of the
permissible total weight of the trailer. Both wheels of the same axle should be braked evenly; the
brake force differential between the left and right trailer side shall not exceed 30%, with 100%
being the higher force.

5 - the link (follower) that couples the pneumatic actuator rod with the expander shaft lever;

6 - pneumatic actuator; 7 - parking brake cable.

Operating instructions. T703 farming trailer 23

Adjust the brakes by changing the expander lever position against the expander shaft. To do

this, jack up the wheel and while turning the wheel, realign the expander lever against the shaft
(on the comb) to feel that the brake shoes slightly rub against the drum.

After a correct adjustment of friction components, the wheel should rotate smoothly, without

cogging or evident resistance (not caused by rubbing of the brake shoes against the drum). Slight
rub of the shoes against the drum, especially on a brand new trailer or following replacement
of the shoes is normal.

Braking force adjustment: the pressure is built in the pneumatic brake system by a three-unit

controller with three control lever positions: empty, half-full and full.

After completing the adjustment, check and adjust the parking brake. The parking brake

is adjusted by setting the cable length that couples the expander shaft lever to the engaging
mechanism. The required sum of braking forces should be produced at the maximum force
applied to the hand crank of 40 daN (at an approximately right angle between the cable and the
expander shaft lever.

INFORMATION!

• Follow these rules when jacking up the trailer wheel:

• couple the trailer with the tractor, move to level ground and

engage the tractor parking brake;

• chock the wheel that is not being jacked up;

• place the jack under the axis and near the jacked up wheel,

and lift the wheel so that it clears the ground;

• secure the wheel against falling by putting a prop of suitable

height under the axis.

• Before driving, periodically inspect all braking components for

proper operation, tightness and clearance. Adjust or repair as
ne cessar y.

IMPORTANT!

• Inspect the brake shoes at least each year. Replace worn shoes.

• In order to achieve the required braking performance after

replacement of friction components, remember to run them in
(by driving with frequent braking), which should be followed by
readjustment.

7.3. Hydraulic system

7.3.1. Hydraulic system – servicing of the load body hydraulic tipping system

The hydraulic oil of the trailer and the external hydraulic system oil (tractor) must always be

of the same grade and type. DO NOT use different oil grades.

The trailer hydraulic system must be absolutely leak-tight. Check the leak tightness of the

hydraulic system by tipping the load body backwards and overloading the hydraulic system for
a few seconds. If there are oil leaks at the hydraulic connections, retighten them. If the problem
persists, replace the hose or the connection ttings. If the hydraulic leak does not occur on any
connector, replace the leaking hydraulic system component. Any and all mechanical damage to
a component requires its replacement with the new one. The condition of the hydraulic system
must be monitored continuously throughout the operating life of the trailer. When coupling the
hydraulic systems of the tractor and of the trailer, keep the couplings as clean as required.

7.3.2. Hydraulic system – adjustment of the load body hydraulic tipping mechanism

The hydraulic system features a safety cable (which is a tipping angle limiter of the load

body) and the cut-off valve that isolates the oil ow to the hydraulic actuator when the body is

Operating instructions. T703 farming trailer 24

tipped. No unauthorised person is allowed to make adjustments or remove the limiters due to
safety concerns. The cut-off valve is intended to isolate the oil feed from the actuator before the
maximum (permissible) tipping angle of the body is reached. Changing the length or breaking
of the safety cable between the load body frame and the cut-off valve installed on the chassis
frame may result in damage of the trailer or a risk of turning over the trailer.

INFORMATION! • Do not remove or disconnect the safety cable / load body tipping

lim iter.

• Unauthorised persons must not adjust the cut-off valve.

7.4. Wheels – tyres

Servicing of the tyres involves checking their condition by visual inspection and checking

the tyre pressure. It is also essential to check that the tyres have no cracks that expose or damage
the carcass, and that the hubs, wheel disks and their fastening in good condition.

INFORMATION! Regularly inspect the wheel nuts (i.e. the condition and tightness

before each use of the trailer); retighten if necessary.

IMPORTANT! • After the rst travels with loads and after each 100 km, inspect

the following:

• the tightness of wheel nuts; retighten if necessary

• tyre pressure. The tyre pressure rating displayed near the

trailer wheels

• applies to transport at the maximum permissible speed (at

the maximum payload).

9. PERIODIC MAINTENANCE

9.1. Lubrication

Lubrication is one of the most critical factors for the good performance of individual

assemblies and mechanisms of the trailer.

Timely lubrication and use of correct lubricants signicantly reduces the risk of damage or

premature wearing of individual parts.

Daily lubrication applies only to the days during which the trailer is operated.

• Follow these rules when lubricating:

• clean the grease nipple before feeding the grease;

• feed the lubricant until fresh lubricant comes out of the gaps (through which the used
lubricant is pushed out rst);

• when nishing the lubrication, leave some lubricant on the nipple head;

• use oil to lubricate threaded joints, lever joints and similar parts of the trailer;

• inspect the lubrication of wheel hub bearings each year; add or replace the bearing lubricant;

• when replacing the lubricant, remove the hub, remove the used lubricant, inspect the bearings'
condition (replace with new ones if necessary); after applying the fresh lubricant, adjust the
bearing play.

IMPORTANT!

• Use only quality bearing lubricants.

• Never drive without the hub cap; otherwise penetration by dirt

(sand) will damage the wheel bearings.

Lubrication point Lubricant grade Lubrication frequency

Wheel hub bearings ŁT 43 Every 6 months

Hydraulic actuator head socket Graphite grease Once a year

Load body tipping system parts ŁT 43 Every 6 months

Support foot components ŁT 43 Every 6 months

Eye catch ŁT 43 Every 6 months

Other lubrication points

• Regularly lubricate movable parts of locks, hinges and articulated joints;

• Pressure-feed the lubricant with a lubricating gun through clean nipples;

• Regularly lubricate movable parts of brakes (levers and pins);

• Lubricate the brake shoe axes only when necessary and only with a small amount of lubricant

Operating instructions. T703 farming trailer 26

9.2. Maintenance and servicing

The transport capacity and long operating life of the farming trailer can only be assured if

the machine is properly and reasonably operated within its design and functional capacities.

Even a slight negligence in operation may result in severe consequences. A timely discovered

fault is easy to remove at a minimum cost and effort, while producing the maximum effect.

Faults of the trailer can only be discovered soon if regular, periodic cleaning and thorough

inspection is carried out.

Hence clean the trailer frequently to observe any damage and faults.
Also carry out periodic technical inspection of the trailer. Lubricate the trailer according the

guidelines for lubrication.

Store the trailer in a sheltered area to protect it from weather conditions and deterioration.
In order to preserve its proper performance, the trailer must be maintained, readily repaired

and thoroughly supervised during its operating life.

Daily servicing (before work) of the trailer includes a certain minimum of actions, i.e.:

• check the screwed components and their safeguards from accidental release;

• check the play of mechanisms and articulated joints;

• check the tightness of the hydraulic system and remove all leaks;

• check the tightness of the pneumatic system;

• functional checks of mechanisms;

• check and perform lubrication according to the instructions;

• check the tyre pressure;

• check the wall locks for proper engagement and security;

• wall top sections in use: do functional tests and check that the parts do not pose risk to trafc
safety and operator's safety;

• functional check of the brake system and the warning and signalling system.

Repair instructions

Small repairs required by accidental faults must be carried out with care for cleanliness,

installation of all parts at their locations and adjustments essential to proper performance of the
trailer.

Small repairs during operation (in the eld) shall be done on site by service personnel.
All parts removed during repairs shall be stored in conditions that protect from dust and

other contaminants. Pay particular attention to protection and cleanliness of bearings.

During eld repairs, keep the area clean when reassembling the parts (the parts which

fell to the ground shall be washed or at least cleaned of dirt to an extent that permits proper
functioning).

During running and general repairs, follow the engineering rules for disassembly and (re)

assembly of parts and subassemblies to ensure proper quality and performance of work.

Do functional tests of trailer mechanisms after each repair.

10. DISPOSAL OF THE TRAILER

If the user decides to dispose of the trailer, hand over the entire vehicle to the nearest scrap

collection point approved by local authorities. The proof of disposal issued by the collection
point is essential for de-registration of the trailer. Recycle the parts which remain from repairs
or have become obsolete.
