Bleed central lubrication system
Bleeding the lubrication system is nec-
essary if the central lubrication system
has been operated with an empty lubri-
cant tank.
- Release the main lubrication line (a)
at the distributor (b).
- Start up the central lubrication sys-
tem with the filled lubricant tank (c).
- Allow the pump to run until lubricant
emerges from the previously re-
leased main line (a).
- Reconnect the main line (a) to the
distributor.
- Release all distribution lines (d) from
the distributor.
- Reconnect all distribution lines as soon as lubricant has emerged.
- Check all connections and lines for leaks.
Check pressure limiting valve
m
If lubricant emerges at the pressure lim-
iting valve (a), this indicates a malfunc-
tion in the system.
The consumers are no longer adequate-
ly supplied with lubricant.
- Release all distribution lines (b)
leading from the distributor (c) to the
consumers in succession.
- If lubricant emerges from one of the
released distribution lines (b) under
pressure, search in this lubrication
circuit for the cause of the blockage
which has triggered the pressure
limiting valve.
- After rectifying the malfunction and
reconnecting all lines, again check
the pressure limiting valve (a) for lu-
bricant emergence.
- Check all connections and lines for
leaks.
