Cleaning/Changing the Filter
1. Remove the high pressure hose from the material inlet
fitting.
2. Holding the material tube at the wrench flats with one
wrench, unscrew the material inlet fitting another wrench.
3. Pull out the cylindrical filter.
4. Rinse the filter in a cleaning solvent or exchange with a
new filter.
5. Push the cone end of the new or cleaned filter into the
into the material tube.
6. Make sure the spring is in position in the material inlet
fitting.
7. Holding the material tube at the wrench flats with one
wrench, thread the material inlet fitting into the material

3. Clean the tip (refer to the tip cleaner in the
Accessories section).
4. Select a larger tip (refer to the AirCoat Tip
Chart in the Accessories section).
1. Select a smaller tip (refer to the AirCoat Tip
Chart in the Accessories section).
2. Increase the material pressure at the pump.
3. Dilute the material according to the material
manufacturer's instructions.
4. Adjust the atomizing air using the gun air
adjustment knob or pressure regulator at
the compressor.
1. Replace the air valve seal (refer to the
“Repairing Air Valve Seals” procedure in the
Maintenance section).
Cause
1. Material pressure set too low.
2. Blocked spray gun filter or pump high
pressure filter.
3. Tip is blocked.
4. Tip is too small.
1. Tip is too large.
2. Material pressure at the pump is set too
low.
3. Material viscosity is too high.
4. Atomizing air is set incorrectly.
1. Damaged air valve seal.
Problem
Insufficient material supply.
Poor spraying pattern.
Leaking air valve.
