GEARBOX – REAR RETAINER - HYDRAULIC DUMPER – POWER STEERING OIL
Check the level about every 50 working hours (Fig. 4), placed on the right-hand side of the gearbox
casing. If necessary, add AGIP ROTRA JD, gearbox oil. Change the oil once a year. To drain the
old oil from the casing, unscrew the plug in the centre of the gearbox casing under the differential
(Fig. 11) Quantity 26 lt. The filter cap is under the load bed (Fig. 9).
The hydraulic oil filter is near the gearbox (Fig. 10). Change once a year.
To make the oil refilling or substitution faster, take off the screw which is located on the gearbox
cover (Fig. 9).
FRONT AXLE OIL
Check the level trough of the cap in the front part of the casing (Fig. 19); change the oil every 500
hours using AGIP ROTRA 85 W 90 gearbox oil, quantity 5 litres.
BRAKE FLUID
Check the level of the brake fluid in the tank which is on the right side of the drive seat (Fig. 6)
every 8 hours. Add brake fluid if necessary. Check the braking system periodically for leaks.
A special tool for venting the brake circuit is available. Connect it in the place of the cap of the tank,
and vent first the rear trailer circuit, and then the front circuit.
Users without the tool can try to vent the circuits using the machine’s pump, but this is not always
successful.
BRAKES REGULATION
Take off the plastic plug placed in the low part of the braking system elements (Fig. 16). Turn the
toothed ring nut downwards.
The parking brake can be regulated operating on the registers located on the braking system
elements (Fig. 17).
ATTENTION!
Grease the transmission universal joint, the articulated joint of the machine and the steering
articulations periodically.
RADIATOR LIQUID
Check the level every 8 hours with the engine cold; if hot, the water may cause scalding.
Replace the liquid once a year.
Capacity 16 litres (Fig. 6).
CAUTION!
In case of liquid loss, after repairing the damage, fill the circuit up, purging repeatedly the air from
the plug, which is placed on the engine in correspondence with the superior sleeve (Fig. 18).
FUEL OIL FILTER
The fuel oil (Fig. 12) is fitted with an electrovalve to stop the engine. The air purging from the
conduits is automatic. However on the filter is positioned a purging screw. Regarding the filter
substitution follow the engine handbook. However we advise to substitute it in case of engine
irregularities.
