Troubleshooting
6001a02
NOTE
The pump operation can be checked from the outside by observing whether the stirring paddle is rotating (e.g.
by triggering an additional lubrication).
For troubleshooting in the case of pumps with integrated control units, please refer to the respective Technical
Description of the printed circuit board.
Fault: The pump motor does not run
Cause :
Remedy:
Power

interrupted
Â
Check the power supply and fuses. If necessary rectify the
fault and/or replace the fuses.
Â

6001a02
NOTE
If a lubricant low-level is available, the low
level is indicated by the flashing light of the
signal lamp in the case of pumps without
printed circuit board. The flashing fre-
quency depends on the speed of the motor.
Reservoir
empty
Â
Fill up the reservoir with clean grease or oil. Allow pump to
run (trigger an additional lube cycle) until the lubricant is-
sues from all the lubrication points.

NOTE
Depending on the ambient temperature
and/or sort of lubricant it may take 10 min-
utes of operation before the pump elements
reach their full lubricant output.
Air bubbles in the lubricant
Â
Trigger an additional lubrication cycle. Loosen the outlet
fitting or the main line at the pressure relief valve. The
lubricant must issue without air bubbles.
6001a02
NOTE
When push-in type fittings are used, the
high-pressure hose which is under pressure
cannet be easily disconnected from the
pressure relief valve. For this purpose,
loosen the pressure relief valve. For this
purpose, filling nipple on the pressure relief
valve in order to relieve the high-pressure
hose.
Unsuitable lubricant has been used
Â
Renew the lubricant. See the Lubricant List (see page 33
and 34).
