Replacing the piston and spring

The average life of a piston and spring will vary depending on the types of material

being sprayed. Replace the piston if the sprayer takes longer than 2 minutes to prime

when well lubricated, or if there is an excess amount of material leaking and you have

tried all of the troubleshooting suggestions listed in this manual. Replace the spring if

you notice that it is broken when you clean the sprayer.

To replace the piston:

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.
