Place the lift truck on level ground with the engine stopped, the mast tilted backward
and lowered as far as possible.
- Open the engine cover (
DESCRIPTION: INSTRUMENTS AND CONTROLS).
- Remove the air intake housing 1 to gain access to the inspection cover.
IMPORTANT
Discard the waste oil in an ecological manner.
Before carrying out any work, thoroughly clean the area surrounding the drain plug and the suction cover on the
hydraulic tank.
DRAINING THE OIL
- Remove the filler plug 2 to ensure that the oil is drained properly.
- Place a container under drain plug (3) and unscrew the plug.
REPLACING THE OIL FILTER
- Carefully clean the outside of the filter and its holder, to prevent dust from getting
into the system.
- Unscrew and discard the filter 4, together with its seal.
- Clean the inside of the filter head.
- Lubricate the seal of the new filter (
FILTER CARTRIDGES AND BELTS).
- Refit the new filter onto its support bracket, hand-tighten it only and lock it with
a quarter-turn.
FILTER PLUG CLEANING
- Remove the cover 5 of filler plug 2 by twisting through a quarter turn.
- Remove and clean the filter 6.
- Clean the filter mounting 7.
- Refit the unit.
CLEANING OF STRAINERS
- Disconnect the hoses 8.
- Remove the access panel 9.
- Unscrew the suction strainers
- 10 in the bottom of the tank.
- Clean the strainers with a compressed air jet.
- Check the condition of the strainers and replace if necessary (
FILTER CARTRIDGES
AND BELTS).
- Refit the unit.
FILLING UP THE OIL
- Clean and refit the drain plug 3 (tightening torque 29 to 39 N.m).
- Fill up with oil (
LUBRICANTS AND FUEL) through filler port 11.
- Check the oil level on dipstick 12 (
10H - DAILY MAINTENANCE).
- Check for any possible leaks at the drain plug.
HYDRAULIC CIRCUIT DECONTAMINATION
- Let the engine run (accelerator pedal at mid position) for 5 minutes without using
any accessories on the lift truck, then for 5 more minutes while using all the hydraulic
movements (except the steering system and the service brakes).
- Accelerate the engine at full speed for 1 minute, then activate the steering system
and the service brakes.
- This operation allows the circuit to be decontaminated by the hydraulic oil filter.
IMPORTANT
It is sometimes necessary to bleed the circuits at the pump inlets when an air bubble has formed during draining. In this
case, refer to your dealer.
