32. RADIATOR - Change coolant

DANGER FLUID UNDER PRESSURE; prior to removing the cap, turn it slowly to relieve the pressure. To avoid burns, do not loosen the radiator cap with an hot engine.

A

Open the panel from the upper side of the engine compartment and remove the filler cap located on the radiator.

MIN

-Dilute "Radiator flushing de-scaling product" or an equivalent product in water, following the dosage indicated on the container. Pour the solution into the radiator when the engine is cold. -Operate the machine with engine at high speed, until it warms-up completely. -Drain the solution. Wait for the engine to cool-off a little, then run water through the radiator filler neck letting it flush through the lower side of the radiator.

Use antifreeze mixed with water at 50% for operation down to - 35 °C (- 31 °F).

33. CLOGGED ENGINE AIR CLEANER -

Replace cartridges

Open the engine left side panel. Remove the cover from canister C loosening the screw. Remove the two filtering elements: one inner B, the other outer A and replace them.

Before installing the elements, clean inside canister C and check that dust discharge valve D, located on the lower side of the cleaner, is clean.

-re-install plug T and pour the coolant slowly through the filler neck of the radiator until it fills completely (up to MAX level) sight gauge A; -retighten the radiator filler cap; -start the engine and let it run for a few minutes, -let he engine cool-off, the top-off the coolant level, through the radiator filler neck.

Note – If the engine cooling system is filled with water instead of coolant (having anti-oxidant, anti-scaling, anti-corrosion properties) flush the system as described here after.

WARNING When using compressed air for cleaning parts, use safety glasses with side shields or goggles, so as to reduce the danger for personal injuries cause by flying particles. Limit pressure to 2 bar, in accordance with local and national regulations.

34. EQUIPMENT HYDRAULIC CIRCUIT - Change oil, clean magnetic rod and suction filter

Important – Keep spare elements of the prescribed type, available from the Sales Organisation, on hand to reduce machine down-time.

Oil draining

-Place the machine on a flat surface, with the equipment resting on the ground. -open the right side panel of the hydraulic oil reservoir; -remove the hydraulic oil filler cap from the reservoir and loosen, plug T to drain the oil from the reservoir. -Clean with solvent the plug T and the magnet Z.

Loosen screws V retaining the filter support. Unscrew filter Fa and wash it. The filter must be washed and inspected at every oil change. If during the inspection the filter appears to be damaged, replace it with a new one.

Oil refilling

Reinstall the magnetic rod and plug, fill the reservoir with oil through the filler neck up to maximum level and tighten cap. Start the engine, move the blade slowly and the ripper a few times, to fill the cylinders and tubes with oil; topoff with oil at various intervals. Check the oil level as described at point (9) of the MAINTENANCE TABLE.

35. FINAL DRIVES - Change oil

Remove lower plug B (one for each final drive) and let all oil drain out. After retightening the plug, refill with new oil through filler plug A. Repeat the operation on both sides.

36. TORQUE CONVERTER TO TRANSMISSION

PROP SHAFT - Grease spiders

Tilt the cab of the machine, as described in the point "TILTING THE CAB". Pump grease (three or four strokes) into the appropriate fitting to lubricate the spiders.

Note – Perform the operation more frequently when the machine operates in extreme dusty conditions.

Grease pivots

Pump grease into the lube fittings of the blade cylinder support. The fittings indicated by arrows are also installed on the opposite side of the machine.

WARNING Stop the machine in accordance with the procedures prescribed in the Operation and Maintenance Manual, prior to lubricating or performing any intervention. Always lower the equipment to the ground prior to performing any type of maintenance operation.
