the motor.
Remedy:

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.

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.

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.
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.
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.
