Bleeding the hydraulic system
Injury hazard due to uncontrolled movements of the loader unit!
Air inclusions in the hydraulic system can cause uncontrolled movements
of the loader unit due to pressure loss.
► Bleed the hydraulic system after replacing the hydraulic oil, in the event
of malfunctions in the hydraulic system, after repairs or after extended
periods in which the machine and the hydraulic system are not used.
► Perform bleeding only when seated on the operator seat.
► Ensure that no one is in the danger zone of the machine.
1. Check the oil level in the hydraulic oil reservoir.
➥ If necessary, add hydraulic oil until the oil level is visible in the
middle of the inspection window.
2. Start the engine.
➥ Let the machine run at idling speed a few minutes.
3. Fully extend and retract the piston rods of all hydraulic cylinders
several times.
4. Turn the steering wheel as far as it will go to either side until the
steering system works correctly and without any sounds.
5. Check the oil level in the hydraulic oil reservoir.
➥ If necessary, add hydraulic oil again until the oil level is between the
“Min” and “Max” marks on the hydraulic oil dipstick.
