MAINTENANCE
4. Thoroughly clean the valve assembly with solvent
and brush.
5. A properly seated valve filled with water and held
vertically will not drip out the bottom of the valve. If
you have properly cleaned the valve and water drips
out the bottom, the valve is worn and needs to be
replaced.
6. Install cleaned or new valve in the pump block and
then fill the valve with light oil or solvent.
7. If none of the above steps work, see Troubleshoot-
ing.
NOTE: The inlet valve must be oiled after every job.
This will reduce or eliminate priming problems the next
time the sprayer is used. See Figure 43.

3. Test movement of the valve by pushing on it from the
open end of the valve housing with the eraser end of
a pencil or a screwdriver. It should move about 1/16
inch. If it doesn't move, it is probably full of dry paint
or other debris and should be cleaned or replaced.
