The electro-hydraulic unit must be cleaned and dried after each use. The pump is basically
maintenance free, only the oil level must be checked regularly and the pump has to be
inspected for possible damages and wear.
To check the oil level of the unit see the oil level control glass (Pos.-No. 5). If the oil level
proves to be unsatisfactory (below the min. mark) additional oil has to be added. To do that
open the oil filler plug (Pos.-No. 4) and fill in the oil. After servicing the oil filler plug
must be screwed on again.
The hydraulic hose (Pos.-No. 9) and the armature must be checked for damage and
leakage.
