Before proceeding, follow the Pressure Relief
Procedure outlined previously in this manual.
Additionally, follow all other warnings to reduce the
risk of an injection injury, injury from moving parts
or electric shock. Always unplug the sprayer before
servicing!
7.1

Removing and Cleaning the Inlet Valves

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 (0,15 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 sprayer is used.
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.

2. Remove and clean the ball guide (3) and small spring (4) inside
the valve using a wire hook or tweezers. Replace the spring if
it is broken or worn.

i
tension. Do not put in an unauthorized substitute.
See the paint pump assembly parts diagram for the
proper replacement part number.
3. Remove the seat (1) and ball (2) 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.
you will need to align the ridge on the seat with the
i
groove in the pump housing when reassembling.
6. Drop in the valve ball (1).
7. Insert the ball guide (3) and spring (4) and replace the valve
body (5). Be sure that the o-ring (6) is positioned properly and
that the tongue on the cap fits inside the spring.
