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
Thermal overload
protector cuts out
repeatedly
1. Low voltage 1. Check voltage at wall outlet with voltmeter.
2. Wrong gauge wire or length of
extension cord
2. Check extension cord chart for proper extension cord usage.
3. Clogged intake filter 3. Clean or replace filter.
4. Lack of proper ventilation/room
temperature too high
4. Move compressor to well-ventilated area.
5. Defective check valve 5. Repair or replace.
6. Defective unloader valve (on
pressure switch)
6. Repair or replace.
7. Compressor valves failed 7. Replace valve assembly.
Do not disassemble check valve with
air pressure in tank; bleed tank.
Tank pressure
drops when
compressor shuts
off
1. Loose drain valve 1. Tighten.
2. Check valve leaking 2. Remove check valve. Clean or replace.
3. Loose connections at fittings,
tubing, etc.
3. Check all connections with soap and water solution. If a leak
is detected, (1) tighten or (2) remove fitting and apply pipe
tape to threads and reassemble.
4. Tank leaks 4. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
Do not disassemble check valve with
air pressure in tank; bleed tank.
Compressor runs
continuously and
air output is lower
than normal/low
discharge pressure
1. Excessive air usage, compressor too
small
1. Decrease usage or purchase unit with higher air delivery
(SCFM).
2. Clogged intake filter 2. Clean or replace.
3. Loose connections at fittings,
tubing, etc.
3. Check all connections with soap and water solution. If a leak
is detected, (1) tighten or (2) remove fitting and apply pipe
tape to threads and reassemble.
4. Tank leaks 4. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
5. Broken valves 5. Replace compressor valves as necessary.
6. Piston ring worn 6. Replace piston rings.
Excessive moisture
in discharge air
1. Excessive water in tank 1. Drain tank.
2. High humidity 2. Move to area of less humidity; use air line filter.
NOTE: Water condensation is not caused by compressor
malfunction.
