that has already been filled. Do not mix hydraulic oils
from different manufacturers. Only use hydraulic oil spe-
cified in accordance with DIN 51524-2 when refilling.

Depending on the model, the empty hydraulic oil tank
has a volume of 22 or 35 litres. Only use hydraulic oil
specified according to DIN 51524-2 in the hydraulic sy-
stem. Select the viscosity class according to the local
ambient temperature. Observe the following list.

WARNING!
There is a risk of injury from oil splashing out under
pressure. Damage to health caused by incorrect
handling of hydraulic oil is possible.
- Always wear safety glasses, gloves and protective
clothing.
- Avoid direct contact with hands, skin and eyes.
- First switch off the machine at the main switch and
take suitable measures to prevent it from being
switched on again accidentally. A suitable measure
is, for example, the attachment of a warning sign.
ATTENTION!
- When refilling, always make sure that the oil drain
plug is properly inserted and tightened before fil-
ling the hydraulic oil.
- If the hydraulic oil is to be replaced, place an oil
tray under the oil drain plug. When selecting the oil
tray, ensure that there is a maximum of 36 litres of
oil in the oil tank.
- When filling, make sure that the hydraulic oil does
not run to the ground and that there is a danger
point. Use a funnel as a preventive measure.
- If the oil temperature is high, allow the entire hy-
draulic system to cool down before refilling or
changing.
- Observe the danger area.

- Hydraulic oil is flammable. Do not use an open fire
while refilling or replacing hydraulic oil.
- Do not inhale vapours that may escape from the hy-
draulic system.
- Dispose of used oil in accordance with the cur-
rently valid legal regulations.
