CHANGE
Place the lift truck on level ground with the I.C. engine stopped and mast tilted backward and
lowered as far as possible.
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 (fig. E5/1) and unscrew the plug.
- Open the I.C. engine bonnet.
- Remove filler cap 2 (fig. E5/2) in order to ensure that the oil is drained properly.
Dispose of the drain oil in an ecological manner.
CLEANING THE STRAINER
- Remove the side panel 3 (fig. E5/3) (3 fastening screws).
- Disconnect the hoses 4 (fig. E5/4) (according to model of lift truck).
- Remove the inspection cover 5 (fig. E5/4).
- 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 5 (fig. E5/4).
- Reconnect the hoses 4 (fig. E5/4) (according to model of lift truck).
- Refit the side panel 3 (fig. E5/3).
FILLING UP THE OIL
- Clean and refit drain plug 1 (fig. E5/1) (tightening torque 29 to 39 N.m).
- Fill up with oil (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL) by filler port 6 (fig. E5/2).
Use a clean container and funnel and clean the underside of the oil drum before filling.
- Check that the oil level on the dipstick 7 (fig. E5/5), is mid-way between the two indicator
marks.
- Check for any possible leaks at the drain plug.
- Replace filler plug 2 (fig. E5/2) with a new filler plug (see: 3 - MAINTENANCE: FILTERS CARTRIDGES
AND BELTS).
HYDRAULIC CIRCUIT DECONTAMINATION
- Let the I.C. 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 I.C. 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.
