8.3 Bleeding the 40PGA pump unit of air
If there are air bubbles in the pump, the lu-
bricant pressure in the header will not reach
sufficient levels.
To bleed the pump of air:
1. Disconnect the header tube from the
pump outlet.
2. Start the pump.
3. Keep restarting the pump until no air
bubbles come out of the pump.
4. Reconnect the header tube to the pump
outlet.
8.4
Priming the header piping and bleeding it
of air
To prime the header piping and then bleed
it of air:
1. Remove the mounting rail stopper plugs.
2. Run the pump until no air bubbles come
out of the stopper plug openings.
3. Reinstall the stopper plugs starting from
the plugs closest to the pump.
4. Make sure the lubricant reservoir does
not run dry in the process. Once bleeding is
complete, refill the reservoir if necessary.
8.5 Lubrication tubes and hoses
Before installation, prime all lubrication
tubes or hoses using a grease gun. If re-
quired, also apply grease to the lubrication
point.
8.6 Cleanliness
Absolute cleanliness must be observed
when installing, adjusting or servicing the
system. If you suspect that the header pip-
ing or lubrication tubes or hoses have been
contaminated, remove all stopper plugs or
connectors and pump lubricant through the
system until all impurities have been purged
from the header piping.
