Changing the hydraulic oil
Change the oil while the plant is at operating temperature (not later than 15
minutes after switching off the shredder).
The hydraulic filter should be replaced when changing the hydraulic oil.
Only use new hydraulic oil of purity class 18/13 according to ISO 4406 or better.
The shredder is equipped with a hand-operated pump for replacing the hydraulic oil. The
pump is mounted on the inside of the right tank door. By turning the screw in the respective
direction, the hydraulic unit can be filled or emptied using the pump.
Pumping out the old oil
1. Unscrew the protective cap from the oil drain plug of the hydraulic tank.
2. Remove the hydraulic hose with quick-release coupling from the hand-operated pump
and connect it to the oil drain plug.
3. Hang the second hydraulic hose into a suitable container.
4. Pump the oil out with the hand-operated pump. Remove the hydraulic hose from the
tank and screw on the protective cap.
5. Dispose of the used oil according to the valid regulations.
Refilling hydraulic oil
1. Hang the hydraulic hose of the hand-operated pump without quick-release coupling into
a container containing fresh oil.
2. Flush the hand-operated pump by pumping fresh oil into the old oil container with four or
five revolutions of the hand-operated pump.
3. Connect the hydraulic hose of the hand-operated pump to the upper hydraulic oil pipe
using a quick-release coupling.
4. Open the measuring connection on the hydraulic oil cooler (next to the upper hydraulic
hose connection) and open the vent valve on the suction/return filter.
