HYDRAULIC CIRCUIT DECONTAMINATION
- Let the engine run (accelerator pedal at mid position) for 5 minutes without using
any accessories on the lift truck, then for 5 more minutes while using all 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 allows the circuit to be decontaminated by the hydraulic oil filter.
IMPORTANT
It is sometimes necessary to bleed the circuits at the pump inlet when an air bubble forms during draining.
Then consult your dealer.
