Replacement Parts
notice:
Parts of your sprayer wear out with use and require regular replacement.
They include the atomizer valve, piston and spring. These parts are not
covered by your sprayer warranty.
More abrasive materials such as latex paints and stains cause these parts
to wear out faster than less abrasive materials such as oil-based paints
and stains, thin stains and sealers.
atomizer valve:
The atomizer valve is shaped to cause the material to spin as it comes out of
the sprayer. The spinning breaks the material up into a fine spray. As more
material goes through the atomizer valve, it wears out the valve and the
shape of the valve changes. When it changes too much to produce a good
spray pattern, the valve needs to be replaced.

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 20 seconds with the
suction tube to prime when well lubricated, or if there is an excess amount
of material leaking, refer to the troubleshooting suggestions listed in this
manual. Replace the spring if you notice that it is broken when you clean the
sprayer.
To replace either the atomizer valve or the piston and spring, follow the
Cleanup instructions on page 9, and replace the old parts with new ones.
When replaced, follow Reassembly instructions, page 10.
