CHANGE
Place the lift truck on level ground with the I.C. engine stopped, the mast tilted backwards
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 and get
rid of it.
Dispose the drain oil in an ecological manner.
CLEANING THE STRAINER
- Disassemble the side panel 3 (fig. E5/3) (3 fastening screws).
- Disconnect the hoses 4 (fig. E5/4) (as model of lift truck).
- Remove the inspection panel 5 (fig. E5/4).
- Unscrew and clean the strainer using a compressed air jet, check its condition and
replace if necessary (see: 3 - MAINTENANCE: FILTERS CARTRIDGES AND BELTS).
- Refit the strainer and the inspection panel 5 (fig. E5/4).
- Connect the hoses 4 (fig. E5/4) (as model of lift truck).
- Reassemble 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.
- Observe the oil level on dipstick 7 (fig. E5/5), the oil should be equidistant between the
lower and the upper marks.
- Check for any possible leaks at the drain plug.
- Replace a new filler plug 2 (fig. E5/2) (see: 3 - MAINTENANCE: FILTERS CARTRIDGES AND
BELTS).
POLLUTION ABATEMENT OF THE HYDRAULIC CIRCUIT
- 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 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.
