Removal
1. Engage trigger lock and pull relief valve UP to
release pressure.
2. Remove material cup and suction tube.
3. Hold sprayer upside-down and use wrench or
socket to loosen and remove inlet fitting, inlet valve,
and spring.

needle-nose pliers to remove if needed. Inlet cavity

possible. Make sure you also clean spring (a), o-ring
(c), and top of inlet fitting (d).

on inlet valve (b).
1. Place inlet valve (b) with spring (a) on top of inlet fit-
ting (d). Push inlet fitting up into pump cavity.
2. Hold inlet in place and turn sprayer upside-down.
Remove inlet fitting and visually check to see that
inlet valve has seated correctly.
3. Replace inlet fitting and use wrench and socket to
tighten to 10 ft-lb.

lightly push on inlet valve to make sure it moves up
and down freely.
