Maintenance

Follow these procedures when encountering problems indicated
in the troubleshooting section.

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 1/16 of an inch. If it does not move, it
should be cleaned or replaced.
NOTE: The inlet valve must be oiled
after every job. This 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.

Removing and cleaning the Outlet valve

It may be necessary to remove and clean the outlet valve or to
replace parts inside the valve worn out through normal use.
1. Remove the outlet valve nut with a wrench.
2. Remove and clean the ball stop and small spring inside
the valve using a wire hook or tweezers. Replace the
spring if it is broken or worn.
NOTE: This spring is manufactured to a very specific
tension. Do not stretch the spring. Do not put
in an unauthorized substitute. See the paint
pump assembly parts diagram for the proper
replacement part number.
3. Remove the seat and ball assembly.
4. Clean all parts thoroughly. If the ball or seat show any
sign of wear or damage, replace them with new parts.
This carbide ball must seal tightly against its seat for the
valve to function properly.
5. Cover all parts with a thin coat of light oil before
reassembling.
6. Drop in the valve ball.
7. Insert the protector and spring and replace the valve body.
Be sure that the O-ring is positioned properly and that the
tongue on the cap fits inside the spring.
8. Tighten the valve body securely with an adjustable
wrench. Do not over-tighten.
NOTE: Wear on the ball is almost impossible to
detect visually. To test for a worn outlet valve
assembly, turn the pressure control knob
clockwise to its highest setting and run water
only through the pump for 10 to 15 minutes
without triggering the gun.
If the valve is defective, the end cap will get very
hot to the touch. If it is functioning properly, it
will stay approximately the same temperature as
the water running through it.
