Discard the waste oil in an ecological manner.
Before any intervention, thoroughly clean the area surrounding the drain plug and the suction cover on the hydraulic
tank.
DRAINING THE OIL
- Place a container under drain plug 1 and unscrew the plug.
- Open the engine bonnet.
- Remove the filler cap lock 2.
- Remove filling plug 3 to ensure that the oil is drained properly.
CLEANING THE STRAINER
- Remove the side panel 4.
- Disconnect the hoses 5 (depending on the model).
- Remove the inspection cover 6.
- Unscrew the suction strainer at the bottom of the tank, clean it with the help
of a compressed air jet, check its condition and change it, if necessary (see: 3 -
MAINTENANCE: FILTERS CARTRIDGES AND BELTS).
- Refit the strainer and the access panel 6.
- Disconnect the hoses 5 (depending on the model).
REPLACING THE BREATHER
- Unscrew the breather 7 and replace it with a new one (see: 3 - MAINTENANCE:
FILTERS, CARTRIDGES AND BELTS).
- Refit the side panel 4.
FILLING UP THE OIL

- Fill up with oil (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL) through filler port 8.
t
IMPORTANT
t
Use a clean container and funnel and clean the underside of the oil drum before filling.
- Observe the oil level on dipstick 9; the oil level should be between the mini and
maxi marks on the dipstick.
- Check for any possible leaks at the drain plug.
- Refit the filler cap 3 and its lock 2.
HYDRAULIC CIRCUIT DECONTAMINATION
- Let the engine run (accelerator pedal at halfway travel) for 5 minutes without using
anything on the lift truck, then for 5 more minutes while using completely the
hydraulic movements (except the steering system).
- Accelerate the engine at full speed for 1 minute, then activate the steering system.
- This operation makes a pollution abatement of the circuit possible through the
hydraulic return oil filter.
