Troubleshooting Chart
Stop using tool immediately if any of the following problems occur. Serious personal injury could occur.
Any repairs or replacements must be done by a Qualified Service Person or Authorized Service Center.
Symptom Possible Cause(s) Corrective Action
Compressor will
not run
1. Switch in OFF position 1. Make sure compressor is plugged in and switch
is ON
2. No electrical power at wall outlet 2. Check circuit breaker or fuse at electrical panel.
3. Compressor has reached automatic
shut-off pressure
3. Release air from tank until compressor restarts automatically
4. Motor overheated / overworked 4. Switch unit to OFF, wait 30 minutes to cool, turn ON again
to resume work. Make sure compressor is run in a clean,
well-ventilated area where temperature will not exceed
100°F.
5. Loose electrical connection 5. Check all electrical connections
6. ON / OFF switch bad 6. Replace ON / OFF switch
7. Pressure switch bad 7. Replace pressure switch
8. Defective motor 8. Replace pump / motor assembly
Thermal overload
protector cuts out
repeatedly
1. Lack of proper ventilation / room
temperature too high
1. Move compressor to a clean,well ventilated area where
temperature will not exceed 100°F.
2. Excessive air usage, compressor too
small
2. Decrease usage or purchase unit with higher air delivery
(SCFM)
Tank pressure
drops when
compressor shuts
off
1. Open tank drain valve 1. Close tank drain valve
2. Loose connections (fittings, tubing,
air hose, any connections, etc.)
2. Check all connections with soap and water solution. If a leak
is detected, tighten. Or remove fitting and apply pipe tape
to threads and reassemble.
Do not disassemble check valve with air in
tank, bleed tank first.
3. Tank leaks 3. Check entire tank for leaks with soap and water solution.
Compressor runs
continuously / air
output lower than
normal
1. Excessive air usage, compressor
too small
1. Decrease usage or purchase unit with higher air delivery
(SCFM)
2. Open tank drain valve 2. Close tank drain valve
3. Loose connections (fittings, tubing,
air hose, any connections, etc.)
3. Check all connections with soap and water solution. If a leak
is detected, tighten. Or remove fitting and apply pipe tape
to threads and reassemble.
4. Pump wore out 4. Replace pump / motor assembly
Excessive moisture
in discharge air
1. Excessive water in tank 1. Drain tank, tilt tank to remove moisture
2. High humidity 2. Move to area of less humidity; use air line filter
Safety valve pops
open
1. Defective pressure switch 1. Replace pressure switch
2. Defective safety valve 2. Replace safety valve with genuine replacement part
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is high or when
a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint
spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun as droplets mixed with
the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than water based paints.
If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective. A filter in the air line (MP3105),
located as near to the gun as possible, will help eliminate this moisture.
