GEARBOX OIL

Change the oil every 1000 hours using SAE 80 W 90 gearbox oil. Quantity: 2,5 kilos. The cap is under the

front gearbox casing (Fig. 14 ref. C). The cap to pour in the oil is on the central gearbox casing (fig. 14, ref.

B). It is possible to adjust the cables by means of two adjustment nuts (ref. Fig. 17)

REAR AXLE OIL

Change the oil every 1000 hours using SAE 80 W 90 gearbox oil. Quantity: 1,6 kilos.

The cap is under the central casing (Fig. 18 ref. B). The cap to pour in the oil is on the central casing (fig. 16,

ref. A).

BRAKE FLUID

Check the brake fluid level in the reservoir on the dashboard every 8 hours (fig. 2 ref. 9). If necessary add

DOT.4 (SAE J 1703) brake fluid. Check the braking system periodically for leaks. If it is necessary to bleed,

proceed as follows: if you have the special tool, connect it in the place of the tank cap; bleed the rear trailer

circuit first, then the front circuit.

Users without the tool can try to bleed the circuits using the machine's pump, but this operation is not always

successful. The bleed screw is on the brake tongs (fig. 19 ref. A).

NOTE Clean the tank cap (fig. 2 ref. 11) and the surrounding surface thoroughly. Pay attention when opening

the cap in order to avoid possible impurities entering the tank. For filling up always use a funnel with an

integrated filter with a 0,12 mm or smaller mesh.

WARNING The brake fluid absorbs humidity, therefore, if the vehicle is mainly used in areas with a high

percentage of humidity, the liquid has to be changed once a year.

CAUTION! The brake fluid is poisonous and highly corrosive. In case of accidental contact, immediately

wash the affected parts with water and neutral soap, then rinse well.

BRAKE ADJUSTMENT

The disk brakes of the service brake are self-adjusting.

The parking brake can be adjusted operating on the register located on the cable (Fig. 4A)

IMPORTANT!

Grease the universal joint, the steering joints periodically (fig. 24) and the adjustment greaser (fig. 25).

AIR FILTER

The air filter is placed under the body (fig. 15). In dusty areas, daily cleaning is recommended.

RUBBER TUBINGS

For the maintenance of the rubber flexible tubings of the brake and feed system, follow the instructions in this

chapter accurately. Ozone, high temperatures and long lack of liquid in the system can cause the tubings to

harden and break, leading to possible liquid leaks. Attention is therefore necessary.

ELECTRICAL SYSTEM (FUSE BOX)

The electrical system is protected by fuses, which once interrupted, cause the total inefficiency of the whole

electrical system. They are placed in front of the passenger's seat (fig. 26).

Once the failure has been sorted out you need to replace the fuse with one having the same capacity. Never

replace with a fuse having another capacity. If the inconveniences should continue after having done the above

mentioned actions, contact an authorised Grillo Dealer.

OIL FILTER BULB

This component engages the oil warning light as soon as oil is missing. (fig. 21)

LOAD BED LIFTING ELECTROVALVE

In fig. 22 you can see the electrovalve that manages the load bed's tipping.

PRIORITY VALVE

In fig. 23 you can see the priority valve that divides the oil flux between the power steering to the piston engine

exhaust electrovalve.
