CHANGE
Place the lift truck on level ground with the I.C. engine stopped and telescope jib retracted
and lowered as far as possible.
Before any intervention, thoroughly clean the area surrounding the drain plugs and the
suction cover on the hydraulic tank.
DRAINING THE OIL
- Place a container under drain plug 1 (fig. E3/1) and unscrew the plug.
- Open the side bonnet.
- Remove filler cap 2 (fig. E3/2) in order to ensure that the oil is drained properly.
Dispose the drain oil in an ecological manner.
CLEANING THE STRAINER
- Remove the inspection panel 3 (fig. E3/3).
- Remove and clean the strainer using a compressed air jet, check its condition and
replace if necessar y (see: 3 - MAINTENANCE: FILTERS CARTRIDGES AND BELTS).
- Refit the strainer and tighten the inspection panel 3 (fig. E3/3) making sure the seal is
in the correct position.
FILLING UP THE OIL
- Clean and refit drain plug 1 (fig. E3/1) (tightening torque 29 to 39 N.m).
- Fill up with oil (see: 3 - MAINTENANCE: LUBRICANTS AND FUEL) by filler por t 4 (fig. E3/2).
Use a clean container and funnel and clean the underside of the oil drum before filling.
- Obser ve the oil level on dipstick 5 (fig. E3/4) ; the oil level should be at the level of the
red point.
- Check for any possible leaks at the drain plug.
- Replace filler plug 2 (fig. E3/2) with a new filler plug (see: 3 - MAINTENANCE: FILTERS
CARTRIDGES AND BELTS).
- Close the side bonnet.
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 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.
