ATTENTION
ATTENTION
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The sealing rings (O-rings) in the electro-hydraulic drive units are subject to
wear. These must therefore be checked and renewed from time to time. In case
of poor bending force or loss of oil, the drive unit must be inspected and repaired
by a ROLLER authorised customer service station.
The gear runs in a life-long grease fi lling and therefore needs no lubrication.
The DC motor of the ROLLER’S Hydro-Polo 22 V has carbon brushes. These
cannot be replaced; the DC motor must be replaced.
NOTICE
Damaged or worn back former supports, back formers and bending formers
cannot be repaired.
