REPLACING THE PISTON AND SPRING
The average life of a piston and spring will vary depending on
the types of material being sprayed.
1. Make certain the sprayer is unplugged.
2. Turn the spray tip
counterclockwise
until it is removed.
Be careful not to lose the swirl valve.
3. Pull out the swirl valve.
4. Turn the locking nut
counterclockwise
until it is removed.
5. Slide the pump housing assembly off of the sprayer.
6. Pull the piston and spring off of the pump housing.
7. Pull the spring off of the piston and throw away the old piston.
8. Slide the spring onto the front end of the new piston.
9. Insert the piston into the back end of the pump housing.
10. Insert the pump housing assembly into the front of the sprayer.
11. Place the locking nut onto the motor housing.
12. Press in while turning the locking nut
clockwise
and tighten
firmly by hand.
Do not cross-thread the locking nut. Make certain it is
threaded correctly before tightening. Make certain that the
pump housing is pushed far enough into the sprayer and
that the locking nut is screwed on tightly.
13. Insert the swirl valve into the front end of the pump housing.
14. Place the spray tip onto the pump housing and turn it

clean the sprayer.
