4.1. Inspection/repair
WARNING
WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The gearbox of the drive unit in the REMS Power-Press SE is maintenance -
free. They operate in a permanent grease fi lling and therefore require no
lubrication. The motor of the REMS Power-Press SE, REMS Power-Press,
REMS Power-Press ACC, REMS Power-Press XL ACC and REMS Power-
Ex-Press P-CEF ACC has carbon brushes. These are subject to wear and
must therefore be inspected or replaced from time to time. Only use genuine
REMS carbon brushes. The REMS Power-Press SE drive unit has a safety
slip clutch. This is subject to wear and must therefore be checked and renewed
from time to time. Use only an original REMS safety slip clutch. In the battery-
operated drive units, the carbon brushes of the motor are subject to wear.
These cannot be replaced; the DC motor must be replaced. The sealing rings
(O-rings) wear in all electro-hydraulic drive units. These must therefore be
checked and renewed from time to time. If the pressing power is insuffi cient or
oil is lost, the drive unit must be inspected and if necessary repaired by an
authorised REMS after-sales service facility.
NOTICE
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings, adapter
tongs, pressing heads or expanding heads cannot be repaired.
