MAINTENANCE
Parts of your sprayer wear out with use and require regular
replacement. They include the swirl valve. _3iston 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.
Replacing the swirl valve
The swirl 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 swirl
vaive, it wears out the valve and the shape of the valve
changes. When it changes too much to prcduce a good spray
pattern, the vaJve needs to be replaced.
