Maintenance
Follow these procedures when encountering problems indicated in
the troubleshooting section.
8.1
Removing and Cleaning the Inlet Valve
1. Perform the Pressure Relief Procedure, turn off and unplug the
unit.
2. Remove the inlet valve assembly using a 27 millimeter socket
or box end wrench.
3. Test movement of the valve by pushing on it from the open
end of the valve housing with a screwdriver or the eraser end
of a pencil. It should move about 1.5 mm. If it does not move,
it should be cleaned or replaced.
The inlet valve must be oiled after every job. This
i
will reduce or eliminate priming problems the next
time the unit is used as well as extend the life of the
valve.
4. Thoroughly clean the valve assembly with water or the
appropriate solvent. Use a small brush.
5. If the valve has been properly cleaned and water drips out of
the bottom, the valve is worn and needs to be replaced. A
properly seated valve filled with water and held vertically will
not drip.
6. Install a new or cleaned valve in the pump block and then fill
the valve with light oil or solvent.
