Vent the central lubrication unit
The venting of the lubrication system be-
comes necessary if the central lubrica-
tion unit was operated with an empty
lubrication tank.
- Untighten the main line (a) of the lu-
brication pump at the flow divider (b).
- Start the operation of the central lu-
brication unit with the refilled lubri-
cant tank (c).
- Leave the pump running until grease
is squeezed from previously untight-
ened main line (a).
- Retighten the main line (a) at the
flow divider.
- Remove all the manifold lines (d) at the flow divider.
- Reconnect again the manifold lines once lubricant is discharged through them.
- Check the tightness of all the connections and lines.
Check the pressure limiting valve
m
If lubricant is discharged at the pressure
limiting valve (a), this refers to failure in
the system.
The consumers receive not enough lu-
bricant.
- Disconnect the manifold lines (b),
which run from the flow divider (c) to
the consumers, one after the other.
- If lubricant is ejected from one of the
disconnected distribution pipes (b)
under pressure, then the clogging,
which led to the tripping of the pres-
sure limit valve, must be searched
for in this lubrication circuit.
- After correcting the fault and the re-
peated connection of all the lines,
check once again for lubricant dis-
charge from the pressure limit valve
(a).
- Check the tightness of all the con-
nections and lines.
