Maintenance

Follow these procedures when encountering problems
indicated in the troubleshooting section.
Removing and Cleaning the Inlet Valves
1. Be certain that the sprayer is off.
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 sprayer is used.
4. Thoroughly clean the valve assembly with water or the
appropriate solvent. Use a small brush.
5. If you have properly cleaned the valve 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 cap with a wrench.

2. Leave the copper washer under the cap in place.
NOTE: If the copper washer falls out, be sure to
replace it with the same side up. The top will
show the imprint of the end cap, while the
bottom should be perfectly flat to match the
seat in the pump casting.
3. Remove and clean the 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 put in an unauthorized
substitute. See the paint pump assembly parts
diagram for the proper replacement part number.
4. Remove the seat and ball assembly using a 3/8 inch allen
wrench.
5. 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.
6. Cover all parts with a thin coat of light oil before
reassembling.
7. Tighten the valve seat securely with the 3/8 inch allen
wrench.
8. Drop in the valve ball.
9. Insert the protector and spring and replace the cap. Be
sure that the copper washer is positioned properly and
that the tongue on the cap fits inside the spring.
10. Tighten the cap securely with an adjustable wrench. Do
not overtighten.

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 sprayer 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.
