- Examine the oil level on the dipstick 10 (Fig. E1/2), the oil level should be
equidistant between the lower and the upper marks.
- Check for any possible leak at the drain plug.
- Refit the cover 2 (Fig. E1/2).
It may be necessary to bleed the system at the inlet of the pumps, if any air
bubbles have formed during the draining; if so, consult your dealer.
POLLUTION ABATEMENT OF THE HYDRAULIC CIRCUIT
- 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 and the
service brakes).
- Accelerate the engine at full speed for 1 minute, then activate the steering
system and the service brakes.
This operation makes a pollution abatement of the circuit possible through the
hydraulic return oil filter.

RAIN AND CHANGE THE COOLING LIQUID
These operations are to be carried out if necessary or once a year at the
coming of winter.
Place the truck on level ground with the engine stopped and cold.
LIQUID DRAINING
- Lift up the overhead guard or the cabin (See chapter : INSTRUMENTS AND
CONTROLS in paragraph : 2 - DESCRIPTION).
- Disassemble the lower hose 1 (Fig. E4/1) of the radiator.
- Untighten the drain plug 2 (Fig. E4/2) of the engine block.
- Unscrew the filler plug 3 (Fig. E4/3) of the expansion pan and empty the
latter.
- Disassemble the cover plate 4 (Fig. E4/4).
- Remove the filler plug 5 (Fig. E4/5) of the radiator.
- Allow the cooling circuit to drain completely while ensuring that the ports do
not get clogged.
- Check the condition of the hoses as well as the fastening devices and
change the hoses if necessary.
- Rinse the circuit with clean water and use a cleaning product if necessary.
LIQUID FILLING
FOR MACHINES WITHOUT CABS OR FROM N° 139 126
- Reassemble the lower hose 1 (Fig. E4/1).
- Retighten the drain plug 2 (Fig. E4/2) (tightening torque 8 to 12 N.m).
- Slowly fill the circuit with the cooling liquid (see chapter : LUBRICANTS AND
FUEL in the section : 3 - MAINTENANCE) through the filler port 6 (Fig. E4/5).
- Fill the expansion pan to the maximum level.
- Allow the engine to run at idle for a few minutes.
- Check for possible leaks.
- Check the level and top up if necessary.
- Refit the filler plug 5 (Fig. E4/5).
- Reassemble the cover plate 4 (Fig. E4/4).
- Retighten the filler plug 3 (Fig. E4/3).
