Spraying troubleshooting – cleaning the spray gun filter
The filter must be cleaned every time you use your sprayer. When using thicker spray materials, the
filter might need to be cleaned more often.
1.
Perform the "Pressure relief" procedure.
2. a) Unscrew the fitting from the bottom of the spray gun using an adjustable wrench, making sure
not to lose the spring.
b) Unclip the trigger guard from the filter housing by pulling outward from the filter housing.
Unscrew the filter housing.
3. Remove the filter from the spray gun housing and clean with the appropriate cleaning solution
(warm, soapy water for latex paints, mineral spirits for oil-based materials).
4. Inspect the filter for holes (see inset). Replace the filter in case you discover holes.
5. Replace the cleaned filter, tapered end first, into the gun housing. The tapered end of the filter
must be loaded properly into the gun. Improper assembly will result in a plugged tip or
no flow from the gun.
6. Reassemble the spray gun.
Spraying troubleshooting – cleaning the inlet filter
The filter at the bottom of the suction tube may also need cleaning. Check it every time you change
spray containers.
Remove the filter by unscrewing it from the suction tube. Clean the filter with the
appropriate cleaning solution (warm, soapy water for latex materials, mineral spirits
for oil-based materials).
Thread the filter back into place.
If you are still experiencing problems after having completed all the steps in "Spraying trouble-
shooting," refer to the section "Troubleshooting."
Important cleaning notes – read before clean-up
When using latex materials, clean your sprayer and components with water. When using oil-
based materials, use mineral spirits.
Do not use mineral spirits on latex materials, or the mixture will turn into a jelly-like substance
which is difficult to remove.
No matter which cleaning solution you use, make sure to dispose it properly when finished
cleaning your sprayer.
