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. Therefore,
trigger several additional lube cycles.
Air bubbles in the lubricant Trigger an additional lubrication cycle (see fig. 30, page
19). Loosen the outlet fitting or the main line on the pres-
sure relief valve. The lubricant must penetrate without air
bubbles.

NOTE
When push-in type fittings are used, the
high-pressure hose, which is under pres-
sure, cannot be easily disconnected from
the pressure relief valve. For this purpose,
loosen the pressure relief valve or, if exists,
the filling nipple on the pressure relief valve
in order to relieve the high-pressure hose.
Unsuitable lubricant has been used Renew the lubricant (see the lubricant list page 45 and
46).

particles. If there are any, remove them.
