9 Maintenance
9.1 Oil level / Oil change
Check the hydraulic oil level after each operation and fill in new oil, if necessary.
Check the hydraulic power pack for possible leakages.
The cylinder must be retracted for filling in oil.
The oil level is correct, if the oil face is approx. 1 cm below the filling hole.
The 1st oil change should be made after approx. 100 operating hours. The cord packing Ø 6 mm
must be replaced with each oil change. The intervals between the further oil changes depend on
the operating hours and the pollution of the oil.
