CLEANING THE STRAINER

- Disconnect the hoses 4 (fig. E3/3) at the level of the hydraulic return oil filter 5 (fig. E3/3).
- Unscrew the four screws 6 (fig. E3/3) and remove the complete filter 5 (fig. E3/3).
- 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).
- Reassemble the strainer, the filter and re-connect the hoses and the clogging indicator.
FILLING UP THE OIL
- Clean and refit drain plug 1 (fig. E4/1) (tightening torque 29 to 39 N.m).
- Fill up with oil (see : 3 - MAINTENANCE : LUBRICANTS AND FUEL) by filler port 7 (fig. E3/2).
Use a clean container and funnel and clean the underside of the oil drum before filling.
- Observe the oil level on dipstick 8 (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).
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.
