2. No spray exits the nozzle.
A. Insufficient air flow from the compressor may
be caused by clogged piping or a dirty air filter.
Check the piping and clean dirty filters.
B. The suction tube is not connected properly or
is damaged and is leaking air into the nozzle
which disrupts the venturi effect. Replace the
suction tube and its connector.
C. The air hose may be loose and leaking air.
Tighten the air hose connection at the nozzle
and at the compressor.
3. Pressure gauge reads too low.
A. Air is leaking from the nozzle. Inspect the
nozzle cap for proper installation.

defective suction tube.
C. The piston and piston ring in the compressor is
worn out. Replace both.
D. The pressure gauge may be defective or
broken.
Replace it.
4. Pressure gauge reads too high.
A. Piping is clogged. Check the entire piping for
obstructions and replace any defective or
clogged sections.
B. A clogged nozzle or nozzle cap will cause
pressure to rise. Clean thoroughly.
5. Abnormal noise or vibration.
A. The compressor anchor bolts are loose causing
vibration. Re-tighten nuts and bolts.
B. The compressor set-up vibrates due to
unstable position. Set the compressor on
stable ground when operating.
6. Chemical flocculation (clumping) in the
chemical tank.
A. Few chemicals will be subject to this
phenomenon due to over agitation. For these
chemicals use distilled water or
discontinue use.

50 feet.
