6.2.2. Venting the centralized lubrication
system
Warning!
The lubricant may only be fed without
bubbles. Air pockets in the lubricant
adversely affect the function of the
centralized lubrication system and impair
the reliability of lubricant delivery, which
can result in damage to the lubrication
points requiring lubrication.
The process of venting the centralized lubrication
system can be facilitated by:
o Opening the ends of the main lines until bubble-
free lubricant discharges.
o Filling long lubricant line sections before
connecting.
The centralized lubrication system is vented as
follows:
Disconnect the main lubricant lines from the
piston pump. Operate the piston pump until the
lubricant emerging from the outlet is free of
bubbles. Reinstall the main lubricant lines.
Disconnect main lubricant line from master
distributor. Operate the piston pump until the
lubricant emerging from the main lubricant line
is free of bubbles. Reinstall the main lubricant
line.
Disconnect lubricant branch lines from master
distributor. Operate the piston pump until
bubble-free lubricant discharges from all outlets
of the master distributor. Reinstall the lubricant
branch lines.
Finally, check that the entire centralized
lubrication system functions properly.
