Type of malfunction
A. Unitdoesnotstart
B. Unitdoesnotdrawinmaterial
C. Unitdrawsinmaterial,butthe
pressure does not build up
D. Coating material exits at the top of
the uid section
E. Increased pulsation at the spray
gun
F. Poor spray pattern
G. Unitlosespower
Possible cause
1. No voltage applied.
2. Pressure setting too low.
3. ON/OFF switch defective.
1. ReliefvalveissettoSPRAY(p spray).
2. Filter projects over the uid level and
sucks air.
3. Filter clogged.
4. Suction hose/suction tube is loose, i.e.
the unit is sucking in outside air.
1. Tip heavily worn.
2. Tip too large.
3. Pressure setting too low.
4. Filter clogged.
5. Coating material ows through the
return hose when the relief valve is in
theSPRAY(p spray) position.
6. Packings sticky or worn.
7. Valveballsworn.

1. Upperpackingisworn.
2. Piston is worn.
1. Incorrect high-pressure hose type.
2. Tip worn or too large.
3. Pressure too high.
1. Tip is too large for the coating
material which is to be sprayed.
2. Pressure setting incorrect.
3. Volumetoolow.
4. Coating material viscosity too high.
1. Pressure setting too low.
Measures for eliminating the malfunction
1. Check voltage supply.
2. Turn up pressure control knob.
