Check pressure limiting valve
If lubricant emerges at the pressure limiting valve (1), this indicates a malfunction
in the system. The consumers are no longer adequately supplied with lubricant.
The following check need to be carried out:
- Release all distribution lines (2) leading from the distributor (3) to the
consumers in succession.
- If lubricant emerges from one of the released distribution lines (2) under
pressure, search in this lubrication circuit for the case of the blockage which as
triggered the pressure limiting valve.
- After rectifying the malfunction and reconnecting all lines, again check the
pressure limiting valve (1) for lubricant emergence.
- Check all connections and lines for leaks.
