Safety instructions

600 Series

Safety instructions

Handling of heavy loads and load sensor

The loader is equipped with a load sensor system. It gives an audible warning signal and at the same time an indicator lights in the dashboard when there is a risk that the machine tips over its front axle. When the system gives a warning signal the load that is being lifted is too heavy in relation with the lift capacity of the loader. In this case one has to either put more counterweights on the loader or relieve the load that is being lifted.

When the load sensor starts to warn, there is a risk that the machine tips over its front axle. In this case stop lifting of the boom, retract the telescopic boom and lower down the boom slowly. When the load sensor is warning do not steer the machine before the boom is lowered down close to ground level. Lift the boom only when the loader chassis is straight. Keep the load as close to ground as possible.

Never take a heavy load on the loader from high level  e.g. from truck, shelf etc.  risk of tipping over!

Always put the load down on the ground before leaving the machine. When loading, always keep the loader chassis as straight as possible.

Personal safety and protective equipment

Wear safe clothing and personal protective equipment (PPE). Protect yourself against work hazards like noise, ejecting debris or dust for example.

 Noise level at drivers seat can exceed

85 dB(A). Wear hearing protection when working with the loader.

 It is recommended to wear safety

footwear when working with the loader.

 Wear protective gloves when handling

hydraulic hoses.

 Follow regulations regarding

protective equipment. Wear eye protection and hard hat or other protective equipment as needed.

Read Operators Manual of the attachment for more information about protective equipment needed in the work.

Safety frame (ROPS) and safety canopy (FOPS)

Safety frame (ROPS) protects the operator in case the machine tips over. Always fasten the seat belt in order to stay inside the safety frame

protective area. Never take off the safety frame. The loader is also equipped with a falling objects protective canopy (FOPS).

Electric system

Lead acid batteries can produce flammable and explosive gases. Make sure that the ventilation is sufficient and keep arcs, sparks, flames and lighted tobacco away from battery. Battery acid causes severe burns. In case of acid contact, wash immediately with water for several minutes and get medical attention in case of eye contact. Read the instructions for jump start on page 30. Never charge a frozen battery.

Transporting instructions and tie down points

Mount the articulation frame lock, shown on page 26, on the machine during transports. Lower the boom down and take off battery disconnect switch. Remember to remove the frame lock after transport!

Tie down points are located on the rear frame on the sides, and on the front frame close to the boom. Optionally available are the rear bumper and / or behind the rear wheels installed tie down brackets (Art. A418746), in which the straps and slings can be attached.

The loader cannot be towed. It is equipped with hydrostatic transimission and a hydraulic parking brake which can be released only when the engine is running and there is enough pressure in the hydraulic system. In case there is a technical failure and the engine cannot be started or doesnt start, the machine must be lifted e.g. with a forklift truck and transported to service.

The loader can be lifted by mounting appropriate lifting slings on the ROPS frame or on the cab LX/DLX. Before lifting, the attachment and eventual extra weights must be removed. Mount the frame lock on the machine.

Make sure that the lifting slings cannot move and that the machine doesnt swing during lifting. Follow the instructions given in the operators manual of the lifting slings.

Lift a loader with ROPS frame with four straps or slings approved for lifting and minimum 2 metres in length. Loop the lifting straps around the four ROPS posts. To lift a loader with cab LX or DLX, four appropriate lifting eyelets must be mounted and hooks and chains are required.

Lifting kit A418706 includes all necessary parts to lift a loader with ROPS frame. Kit A417352 to lift a loader with cab LX/DLX with detailed instructions included.

Lower the boom and mount the articulation frame lock as shown on page 26. Remove heavy attachment and extra counterweights before lifting. Never lift a loader with persons riding the machine.

Eyelets on extra side counterweights are for installing or removing the sideweight only. Never attempt to lift the loader from the counterweigths or use them as tie-down points.

AVANT 600 series load diagram

The diagrams can be interpreted as follows:

 The diagrams show tipping load and max. load with

the load at different distances from the front axle of the loader

 Example: If the center of gravity of the load is

750 mm in front of the front axle, max. load is about 820 kg with a driver weighing 75 kg and with the 170 kg integrated rear weight mounted on the loader.

 NOTICE: If the driver leaves the machine, tipping

and max. loads are reduced respectively.

 Tipping load and max. load depend both on the

weight of the driver and the eventual extra weights mounted on the loader.

 Please note that the diagrams are based on the

machine operating on a level, even and firm supporting ground. Loads should be significantly reduced when operating on gradients and/or on soft ground.

 The loader is equipped with a load sensor system,

which gives an audible warning signal and an indicator lights up in the dashboard when tipping load is being approached.

 Read the safety instructions regarding handling of

heavier loads. Calibration instructions of the load sensor system can be found on page 30.

the dashboard

lights up When boom floating is being used, it is possible that air gets in the hydraulic system. This can lead to inaccurate boom movements and the boom can give in. Therefore the boom and attachment coupling plate should always be moved to extreme end positions after switching off boom floating. Use boom floating only when necessary.

Smooth drive (option Avant 640)

Avant 640 can be equipped, as an option, with the smooth drive which is a shock absorber system for the boom. When driving at high speed with a heavy load or heavy attachment, the boom starts to move up and down, making driving unpleasant. The smooth drive consists of an accumulator which absorbs and eliminates boom movements and makes driving considerably smoother and more stable. Smooth drive is switched on with the boom floating switch no. 17. Attention! The machine must also be equipped with both boom self levelling and boom floating .

Operating instructions

Joystick (option)

The loader can be equipped, as an option, with a joystick, where the operation of auxiliary hydraulics and telescopic boom is electric.

1. Auxiliary hydraulics

 push the buttons to engage

and disengage auxiliary hydraulics.

2. Telescopic boom

 with the rocker switch the

telescopic boom can be operated steplessly (extension- retraction). Speed of the telescoping function depends on the position of the pump selection lever.

Engine block heater (option)

The loader can be equipped, as an option, with an engine block heater. Engine block heater outlet is on the right side in the rear of the machine.

Trailer coupling (option)

The loader can be equipped, as an option, with a trailer coupling. There are two types available: a 50 mm ball hitch and a 50 mm ball hitch with towing pin. Both can be mounted either directly on the rear bumper or on the extra back weight. Max. allowed vertical load of the trailer coupling is 6900 N, max. towing load is 6000 N.

Make sure that the weight on the trailer is distributed correctly so that the trailer cannot cause an upward lifting force on the trailer coupling

Hydraulic lifting device in the rear (option)

The hydraulic rear lifting device allows mounting of some attachments on the rear of the machine, for example a sand spreader or a rotary hoe. This means that it is possible to use a bucket or a dozer blade at the same time in the front. Hydraulic rear lifing device comes with a double acting auxiliary hydraulics outlet.

Extra counterweights (option)

The loader can be equipped with extra counterweights that are mounted on the rear bumper. Max. amount of extra weights (29 kg/pcs) is 4 pcs. If the machine is fitted with an extra weight with trailer coupling, max. amount of extra weights is 2 pcs. In addition, extra side weight kits (80 kg and 180 kg) are available as an option.

Drive release valve

The switch no. 16, LOCK, controls a valve, which is used to divert the oil flow between left and right side hydraulic motors, and this affects the pulling force. LOCK OFF: In this mode, the hydraulic oil flows in series from motor to motor. The wheels will roll more freely and the loader leaves less tire marks on soft surfaces. LOCK ON: In this mode the hydraulic oil flows in parallel between the hydraulic motors in each side, similar to a differential lock in operation. This improves the towing capability of the loader.

Anti slip valve (option)

The valve positively diverts oil flow between the right and left side hydraulic motors and improves traction on slippery and uneven surfaces. It is engaged by pressing continuously on the switch on the joystick. As soon as the switch is released, anti slip valve is released. The function of the anti slip valve depends also on the position of the drive circuit release switch no. 16: LOCK ON : Anti slip valve diverts oil flow between all four hydraulic motors - all four wheels have best possible traction. Use sufficient engine revs and press properly on the drive pedal. LOCK OFF: Drive circuit released  anti slip valve diverts the oil flow between the front left and right hydraulic motor only, not the rear hydraulic motors.

Work light kit (option)

The loader can be equipped with extra work lights, making it easier to work in low light. The lights are operated with the switch on the control panel (see page 14).

Headlight, beacon, blinker & reflector kit (option)

This optional equipment enables road traffic registration in certain countries. Requirements vary in different countries, please consult your local AVANT distributor.

Stopping the engine

600 Series

Operating instructions

Drive control

AVANT 600 series loaders are equipped with a hydrostatic drive system, there is a variable displacement hydraulic pump in the drive circuit. The oil flow of this drive pump is steplessly adjusted with the two drive pedals. The drive pedals act in a proportional way to control the drive speed and power available at the drive motors.

This hydrostatic driving system has different operating characteristics to a mechanical drive. To get maximum pushing power push the pedals lightly  for higher travel speed push the pedal harder.

When thinking about the function of the two drive pedals, they should be compared to gears, not to a conventional throttle pedal. The drive pedal in a way shifts on a higher gear the more the pedal is pressed. Therefore you shouldnt press the pedal more when the engine starts to struggle. Pressing the pedal just causes the engine to stop.

When you want to have a high pulling force:

1. Use high engine revs

2. Select a relatively slow drive speed with the drive pedal. That is: press the pedal only lightly (= select a low gear). This way the full output of the hydraulic system and the engine can be taken out.

Driving of the machine is controlled with the drive pedals and hand throttle as follows:

Select the revs of the engine with the hand throttle lever on the control panel. The basic rule is: use lower revs for lighter work and higher revs for hard work. When driving, the revolution speed of the engine can be adjusted with the hand throttle lever, if necessary. Do not turn the machine with a high travel speed. Hand throttle also has an effect on the operation speed of a hydraulically driven attachment: the more throttle the faster the attachment operates. Make sure not to exceed max. allowed oil flow of the attachment.

If you want to drive forward, press gently on the right drive pedal until the machine starts to move slowly. The desired drive speed is selected with the drive pedal: the more the pedal is pressed the faster you will travel.

When you wish to stop gently release the pedal by lifting of your foot, and the machine will slow and stop.

Drive backward is controlled with the left drive pedal in the same way as drive forward: the more the pedal is pressed the faster you will travel.

Familiarise yourself with the driving of the machine on low speed and on a flat, even and open place where unintended movements dont cause problems or danger. When you have learned how to drive on low speed, increase speed gradually and learn how to drive with higher drive speeds. Make sure that there are no persons in the operating area of the machine.

ATTENTION! AVANT 640 is equipped with two drive speed ranges. Always start the operation with the lower speed range. See page 15 for instructions how to use the drive speed range selection switch.

Hydraulic oil temperature has an effect on the hydrostatic transmission of the loader. When ambient temperature is below 5º C, let the engine run and the machine warm up properly before starting to drive. Drive carefully until the machine reaches its normal operating temperature.

When hydraulic oil gets warmer, driving characteristics of the transmission change. When the oil is warm and hydraulic oil cooler has switched on, stopping distance of the machine can be longer than normally. If the machine is used constantly in high ambient temperatures, hydraulic oil type and viscosity must be suitable for these conditions. Contact Avant service.

Should there be a disturbance or malfunction in the hydrostatic transmission and consequently the braking force is not sufficient, engage the mechanical parking brake. Parking brake can also be engaged during driving if necessary.

Operating instructions

NOTICE! The engine cannot start if the auxiliary hydraulics control lever is in the locking position.

Going near an attachment that is in operation can cause a serious risk. Switch off auxiliary hydraulics before leaving drivers seat or stopping the engine. Operate the controls only when sitting in the drivers seat.

Steering of the machine

Steering of the machine happens with the steering wheel. The steering wheel is hydraulically powered. A practical way of steering is to steer with your left hand on the knob of the steering wheel. This way your right hand is free to operate other functions.

Pay attention to other machines and persons that are moving in the area. Make sure that there are no persons in the danger zone of the loader and the attachment. The danger zone of the loader covers the reach area of the loader boom, the turning area on the side and in the front and rear of the loader. Always put down the load when leaving the machine  the loader is not designed to stay with the loader boom and load lifted. Learn how to operate the loader in a safe place.

Loader control

The loader boom and bucket are controlled with the multi-function lever sideways (tilt) and back & forward (boom up & down).

 Pull backward to lift the boom  Push forward to lower the boom  Push left to raise the tip of the bucket (filling)  Push right to lower the tip of the bucket (emptying)

Using the auxiliary hydraulics

Auxiliary hydraulics (hydraulically operated attachments) are controlled with the lever no. on the control panel, or with the buttons on the joystick (see page 18). The lever locks in the locking position (on the right) which facilitates operation of the attachments that require constant oil flow (rotary broom, backhoe etc.).

Always remember  safety first. Test all the functions of the loader at an open and safe place. Make sure that there are no persons in the operating area of the machine and the danger zone of the attachment.

When driving, always keep the loader boom as low as possible. Risk of tipping over increases considerably when there is a heavy load on the loader (a heavy attachment or a big load in the bucket) and the boom is up when driving.

Never use a high drive speed when turning. In particular: when the loader boom is up the stability of the machine is much weaker when turning.

Remember that, when turning, the driver´s seat extends beyond the turning radius of the wheels. Stay inside the safety frame (risk of collision and crushing).

600 Series

Do not drive with the cab door open, nor turn the steering wheel when the cab door is open. The door may break.

Do not cover the air vent hole in the cab, located down in the right rear corner, in order that moisture does not condense on the windows.

Cabs

AVANT 600 series can be equipped, as an option, with cab L, LX and DLX. All cabs are ROPS and FOPS certified.

Windscreen washer tank and filler cap on machines with cab LX and DLX are located outside the cab, in front of the windscreen on the left.

On machines with cab L the tank is located behind the front left wheel and the filler opening is on the footboard.

Air conditioning (option for cab DLX)

Cab DLX can be equipped, as an option, with air conditioning. The on/off switch of A/C is located on the panel up to the right. Air conditioning can also be used to remove humidity from the cab. If there is high humidity in the cab, switch on the heater and A/C at the same time so that the air inside the cab dries faster.

ATTENTION! The fan must be switched on in order that A/C will work.

Heater

Cab LX/DLX is equipped with a warm water heater which works like a central heating system, circulating the coolant of the engine. Cab temperature can be adjusted with the rotary switch of the heater. Air flow can be directed with the nozzles on the front panel and in the footwell. Heating efficiency and air flow can be adjusted with the fan. The cab is also equipped with an air circulation system: There is a ventilation hatch below the seat in the footwell. The hatch is opened and closed with the lever in the middle. As soon as the hatch is opened the heating system starts to take warm air from the cab and circulates it through the nozzles back in the cab. This way the cab warms up quicker in cold weather.

NOTICE: Switch off the air circulation as soon as the temperature in the cab is sufficient, otherwise moisture starts to condense on the windows.

The cab is also equipped with a replaceable cab air filter. The filter cartridge (part no. 65118) can be changed from outside the cab, under the door on the left side (see picture above)

Safety

Familiarise yourself with the special drive features and space needs of this articulated loader, equipped with cab, on a flat, even and open place. Remember that, when turning, the cab extends beyond the turning radius of the wheels. This should be taken into consideration especially when driving in confined spaces, in order that the rear of the cab will not get damaged.

If necessary, the windscreen can be broken with the emergency hammer in the cab. This way it is possible to get out of the cab in an emergency situation. The fuse box on machines with cab LX/DLX is located outside the cab, on the right side below the windscreen.

The optional air suspension seat (cab DLX only) is equipped with heater. Seat heater switch is located on the back side of the back rest on the left.

Coupling the attachments

Coupling of the attachments into the attachment coupling plate happens as follows:

Stage 1 :

 Lift up the two locking pins on both sides of the attachment

coupling plate and turn them backward so that they remain in the up position

 Make sure that the pins remain in the up position, otherwise

you cannot couple the attachment properly!

Stage 2 :

 Turn the attachment coupling plate with the tilt movement so

that the upper edge of the plate leans forward.

 Drive the loader into the attachment

Stage 3 :

 Lift the boom a little so that the attachment lifts off of the ground  Pull the boom control lever to the left so that the lower edge

of the attachment coupling plate turns into the attachment

Stage 4 :

 Pull the boom control lever more to the left so that attachment

coupling plate turns more and the brackets on the boom push the pins down in the holes of the attachment.

 Make sure that the pins lock properly down in the holes of the

attachment!

Hydraulic attachment coupling plate (option)

The hydraulic attachment coupling plate enables coupling and disconnecting of the attachment from drivers seat. There is a hydraulic cylinder on the attachment coupling plate which moves the locking pins up and down. The electro-hydraulic system works also when then engine is not running, as long as the ignition switch is in ON position (current on). Control switch is located at the control panel on the right (see page 14).

Always make sure that the locking pins lock properly down in the holes of the attachments. Both pins must be locked. Avoid unintentional dropping of the attachment. Operate the hydraulic coupling only when the attachment is close to ground.

Switch up: Locking released

Switch down: Locking position

Requirements for attachments

 Check max. allowed hydraulic oil flow for the attachment. Adjust engine revs so that they are suitable for

the work and the attachment.

 Read Operators Manual of the attachment before starting operation. Make sure that the attachment is

compatible with the loader. Contact your Avant dealer if necessary

 Make sure that the attachment is connected properly on the attachment coupling plate, and that it is being

used in accordance with the instructions in the Operators Manual. Follow instructions regarding personal protective equipment and safety distances.

 Put the attachment down on the ground and stop the engine before leaving drivers seat. Familiarise yourself

with the operation and stopping of the attachment at a safe place. Follow service instructions.

600 Series

Operating instructions

Make sure that the attachment is properly connected on the attachment coupling plate. An attachment that comes loose may tip over or fall on the loader, causing personal injuries.

Do not try to lock the locking pins by using the brackets on the boom when the attachment is lifted over one metre from the ground. Lock the locking pins by hand and make sure that both pins lock properly down in the holes of the attachment.

Always read also the additional instructions for coupling and using of the attachment in the Operators Manual of the attachment.

Coupling the hydraulic hoses of the attachment

Hydraulic hoses of the attachment are equipped with the multi connector system, which connects all hoses at the same time.

Coupling the multi connector

Align the pins of the attachment connector with correspondig holes of the loader connector. Connecting is not possible if the multi connector for some reason is mounted in a wrong way on the attachment hoses. Connect and lock the multiconnector by turning the lever towards the loader. The lever should move easily all the way to locking poisition. If the lever doesnt move easily, check alignment and position of the attachment and loader side connectors and clean the connectors. Stop the engine and release pressure in auxiliary hydraulics line by moving the auxiliary hydraulics control lever in both directions a couple of times.

Disconnecting the multi connector

 Before disconnecting put the attachment down on a solid and

even surface. Switch off auxiliary hydraulics. Disconnect attachment hoses by pressing on the red button on the multiconnector and simultaneously turn the lever away from the machine.

 After ending operation put the multi connector on its "parking"

on the attachment.

NOTICE! When fitting an attachment, make sure that the hydraulic hoses are not overstretched and are not in a position where they can be trapped during the operation of the machine and attachment.

Service and maintenance instructions

Service parts are available through your Avant dealer or authorized service.

If you are not sure about how to do any service operation, ask for additional information before starting servicing. Contact Avant service.

Installing of service support and frame lock

The frame can be locked with the red frame lock. This way the loader frame stays straight during e.g. transportation. Install the frame lock in the holes on the front and rear frame and secure it with the cotter pin.

Make sure that the boom stays up during maintenance operations by putting the service support on the lift cylinder piston rod. Secure the service support by locking it on the piston rod with the long screw that is on the support.

The red service support of the boom lift cylinder is located at the tip of the boom, behind the attachment coupling plate. The frame lock is located over the articulation joint, under the seat base, and is fastened with a bolt.

Safety instructions for maintenance

 Stop the engine and let it cool down

before starting any service operation.

 Put the service support on the boom lift

cylinder when working under the boom.

 Install the frame lock when lifting the

machine, for instance when changing tyres

Check hydraulic hoses and components only when the engine is stopped and hydraulic pressure is released. Repair all leaks as soon as you have noticed them, because a small leak can quickly change into a big one. Do not operate the machine if you have noticed faults or leaks in hydraulic system. Leaking hydraulic fluid can cause serious personal injuries and is harmful to the environment.

Check hydraulic hoses for eventual cracks and wear. Follow the wear of the hoses and stop operation if the outer layer of any hose has worn out. If there are signs of oil leakage, put a piece of cardboard under the probable leakage place in order to find the leakage. If you find a fault, the hose or the component must be replaced. Contact your Avant dealer or service for spare parts.

Releasing the pressure of hydraulic system

Make sure that there isnt pressure in the hydraulic system that could cause danger during service operations. In order to release the pressure in hydraulic system stop first the engine and lower the boom down completely. Move all control levers, including control lever of telescopic boom and auxiliary hydraulics, to extreme end positions a couple of times. Remember that the boom or attachment can move when releasing the pressure. Move the levers until all movements have stopped.

Wear protective glasses and gloves when servicing the machine.

The fluids in the machine are harmful to the environment. Take waste oil and fluids to recycling station.

Never handle pressurized hydraulic components, because ejection of high pressure hydraulic fluid can cause serious injuries. Do not operate the machine if you have noticed a fault in the hydraulic system. Consult a doctor immediately if hydraulic fluid penetrates your skin.

 Condition of the loader, safety frame, seat belt

and other safety equipment

2. Cleaning of the machine

Cleanliness of the loader is not only a question of outer appearance. All surfaces, painted and others, will stay in better condition when they are cleaned regularly. A clean machine also lasts longer. A dirty machine will run hotter and will collect dirt into the air cleaner, which is likely to damage the engine. Pay special attention to the cleanliness of the engine, the oil tank cover, the engine compartment and the hydraulic pump compartment. The loader can be washed with a pressure washer. However, avoid direct spraying on hydraulic components (hoses, cylinders) and decals. After washing grease all greasing points, also the attachment coupling plate and locking pins.

The loader is equipped with a hydraulic oil cooler, which is located in the front frame on the right side, make sure to clean the oil cooler cell with compressed air every time you are servicing the loader - and even more frequently if the loader is being used in dusty conditions. Take off the right side cover plate before cleaning the oil cooler.

3. Greasing of the machine

Greasing of pivot points is very important in order to avoid wear. Most of the greasing points are on the loader boom. The picture on page 31 shows the location of grease nipples.

4. Battery check

Inspect and clean battery terminals regularly. Check also condition and fastening of battery cables and terminal insulators. Make sure that battery cables cannot chafe against any sharp edges. Check also condition and fastening of battery disconnect switch and cables.

5. Hydraulic oil level

Hydraulic oil level can be checked with the dipstick in the filler. Oil level should be at the lower mark of the dipstick when the loader boom is up. Refill when necessary. Do not let any contaminents enter the hydraulic oil tank during this procedure. There is a breather filter inside the dipstick cap which should be cleaned or changed once a year.

Remember to use the service support (page

26).

6.Changing of hydraulic oil filters

The hydraulic oil return filter is located on top of the hydraulic oil tank, under the front cover. Take off the cover and replace the oil filter cartridge.

Remember to use the service support (page 26).

The hydraulic pressure filter is located in the back frame beside the hydraulic pumps. When unscrewing the filter hold the screw in the housing with a 12 mm allen key and replace the filter.

7. Hydraulic oil change

When changing hydraulic oil, the oil can be removed with a suction pump or by opening the drain plug on the right side of the front frame, next to the articulation joint. In both cases it is important to clean the magnetic drain plug. Hydraulic oil tank capacity is 38 litres. Use ISO VG-46 certified mineral hydraulic oil.

Use of synthetic hydraulic fluids is not allowed.

8. Check and tightening of bolts, nuts and fittings

Check tightness of bolts, nuts and hydraulic fittings regularly.

NOTICE: Tighten wheel nuts after first 5 operating hours. Check tightness of wheel nuts regularly. Wheel nuts shall first be tightened to 120 Nm diagonally opposite and finally tightened to 140 Nm.

9. Check pressure of hydraulic system

Pressure checking points and pressure settings for different functions are as follows: Boom lifting: Pressure is checked from the manometer fitting which is mounted on the main control valve (or from the quick coupler of rear auxiliary hydraulics if the machine is equipped with rear aux. hydraulics outlet.) Pressure is measured with full engine revs and by turning e.g. the bucket tilt control to end position. Pressure setting should be 200 bar.

Service and maintenance instructions

600 Series

Service and maintenance instructions

Auxiliary hydraulics: An adapter (A414508) with conventional quick couplers must be mounted on the multi connector. Pressure is checked from one of the female quick couplers, with full revs and by turning the aux. hydraulics control lever. Pressure setting should be 200 bar. Drive pressure: In order to check the pressure in the drive circuit one needs to mount a pressure gauge in the pressure line in each and every case, if pressure seems to be clearly wrong. There are two pressure relief cartridges which have fixed 370 bar pressure setting.

It is recommended that pressures should only be checked and adjusted by a competent and experienced technician. Call your AVANT dealer if you need assistance.

10. Adjust pressure of hydr. system

If the pressure of hydraulic system does not seem to be correct or pressure check indicates that the pressure is wrong, it can be adjusted. All adjustment screws are protected with a 13 mm nuts and there is a seal ring under each nut. When taking off the nuts make sure that the seal rings doesnt get lost. Adjust the pressure with an allen key, max. 1/8 rounds at a time. See pictures for pressure adjustment points. Boom lifting: Pressure is adjusted from the pressure relief valve at the main control valve. Pressure adjustment screw is on the right, on top of the valve segment (see picture). Adjust by turning the hexagonal head screw which is under the cap (200 bar). Auxiliary hydraulics: Pressure is adjusted from the pressure relief valve at the main control valve. Pressure adjustment screw is on the right, under the valve segment (see picture). Adjust by turning the screw with a screwdriver (200 bar). Drive pressure: Can not be adjusted. If the pressures are clearly wrong one must change the pressure relief cartridges which have 370 bar fixed pressure setting.

11-13 Adjust and change the slide pads on telescopic boom

The telescopic boom is equipped with slide pads. At the lower end of the outer boom there are slide pads made of nylon (nos. 1, 2, 3 and 4). In addition, there are four slide pads (nos. 5,6,7 and 8), made of aluminium-bronze alloy, at the upper end of the inner boom. All slide pads can be replaced, and the nylon slide pads on the outer boom can also be adjusted. This way the natural wear of the slide pads, caused be the use of the telescopic boom, can be compensated.

Slide pads nos. 1 and 2

can be adjusted by mounting thin adjustment sheets between the boom and the slide pad. Extend the telescope almost completely and press the boom against the ground, it is the easiest way to mount the adjustment sheet under slide pad no. 2 . However, if there is substantial wear in the slide pads it is advisable to replace both pad no. 1 and 2.

Slide pads nos. 3 and 4 on the side of the outer boom and slide pads nos. 5, 6, 7 and 8 at the upper end of the inner boom last very long in normal use. Slide pads 3, 4, 5, 6, 7 and 8 should be checked every 400 operating hours. Checking happens by taking the inner boom completely out of the outer boom. If the pads have worn so much that they are level with the boom, change the pads.

Part nos. for the slide pads are:

Slide pad 1 and 2: A48339 Slide pad 3 and 4: A48340 Slide pad 5 and 6: A47922 Slide pad 7 and 8: A48343 Washer under slide pads 5 and 6: A47941 Adjustment sheet, short: A48013 Adjustment sheet, long: A48014

Never exceed the recommended hydraulic pressure settings. Excessive hydraulic pressure will damage the hydraulic pumps, cylinders, and hydraulic motors.

Warranty does not cover damages caused by excessive hydraulic pressure.

The load sensor must be calibrated in case one adds or removes more than two AVANT rear weights (+/ 58 kg) on the machine. Calibrating happens as follows:

1. Mount the amount of rear weights with which you are going to use the loader.

2. Remove the engine cover plate and the lower left side rear cover plate.

3. Lift something so heavy with the loader that the rear wheels lift off the ground.

4. Open the screw pointed by the arrows (see picture) with two 13 mm keys. As the two steel strips come in contact, tighten the screw.

5. Lower the rear wheels back to the ground and mount the cover plates.

6. Check function of the load sensor.

NOTICE: The rear of the loader can not be lifted with a jack in order to do the calibration. The rear wheels must be lifted by using the loader boom in order that the adjustment can be done correctly.

15.-25. Service, engine

AVANT 600 series loaders are equipped with a Kubota diesel engine (see technical specification sheet for the engine type of each model). Service and maintenance instructions for the engine can be found in the Kubota Operators Manual supplied with the loader.

Storage of the machine

Before long term storage clean the loader carefully and check and touch-up painted surfaces if necessary in order to avoid rust damages. Grease the greasing points and put oil on piston rods of the cylinders. Take off the battery and store it in the right way. It is recommended to perform the yearly service before storage. Store the machine indoors if possible. If outdoors storage is necessary, protect the machine with the designated cover (part no. 65478).

Fuse box

The fuse box is located on the right side of the loader boom, seen from drivers seat. first lifting the boom so that the fuse box can easily be reached. Remember to use the service support. The list on the right shows the location and function of each fuse in the fuse box. If the engine does not run and the boom cannot be lifted, the fuses can be checked after removing the right side cover plate. The red indicator no. 18 on the dashboard indicates blown hydraulic oil cooler fan fuse. If the indicator is lit, check the 25A fuse of the oil cooler fan. Contact Avant service if necessary.

Jump start and auxiliary power

The engine can be started with auxiliary power if necessary, by using appropriate (strong enough) jump start cables. Connect first one end of the positive cable to the positive (+) post of the dead battery. Then connect the other end of the positive jumper cable to the positive (+) post of the charged battery. Connect one end of the negative jumper cable to the negative (-) post of the charged battery. Then connect the other end of the negative jumper cable to a solid, non-paint coated metal part of the engine of the dead loader, as far from the dead battery as possible.

Read Operators Manual of the vehicle that is giving auxiliary power, in order to make sure that the vehicle suited for that. The vehicle can get damaged when giving auxiliary starting power.
