Procedure
1. Completely empty the oil tank via the drain plug. Clean the oil tank carefully
from oil and contamination. On older systems with heavy contamination, it may
be necessary to remove the oil tank and ush out with a suitable ushing
agent.
2. Completely empty the hydraulic cylinders, tubes, hoses and the suction hose to
the pump.
3. Change the return lter.
4. Fill the tank with new oil via the return lter. Operate all cylinders carefully to
ensure that they will be lled with oil. Ensure that the pump is lled all the time.
Fill up the tank before it gets empty.
5. Drive for 2 or 3 days.
6. Check that all piston rods of the cylinders are in retracted position. Completely
empty the oil tank via the drain plug and change the return lter. Fill up the oil
tank with new oil and operate all cylinders carefully to ensure that they will be
lled with oil. Ensure that the pump is lled all the time. Check that the oil level
in tank remains in correct level.
NOTE! Synthetic esters can dissolve old contamination. If the
performance of the hooklift appears to deteriorate before
the oil lter change, inspect the lters and change if necessary.
