Maintenance
(continued)
This compressor is
equipped with a
manual reset thermal overload protector
which will shut off motor if it becomes
overheated.
If thermal overload protector shuts
motor off frequently look for the
following causes.
1. Low voltage.
troubleshooting chart
Symptom possible cause(s)
Compressor will not 1. Loss of power or overheating
run
2. No electrical power
3. Blown fuse
4. Breaker open
5. Thermal overload open
6. Pressure switch bad
Motor hums but 1. Low voltage
cannot run or runs
2. Wrong gauge wire or length of
slowly
extension cord
3. Shorted or open motor winding
4. Defective check valve or unloader
Fuses blow/circuit 1. Incorrect size fuse, circuit overloaded
breaker trips
repeatedly
2. Wrong gauge wire or length of
extension cord
3. Defective check valve or under loader
Thermal overload 1. Low voltage
protector cuts out
2. Clogged air filter
repeatedly
3. Lack of proper ventilation/room
temperature too high
4. Wrong gauge wire or length of
extension cord
Air receiver pressure 1. Loose connections (fittings, tubing,
drops when etc.)
compressor shuts off
2. Loose drain lock
3. Check valve leaking
Excessive moisture in 1. Excessive water in air receiver
discharge air
2. High humidity
Compressor runs 1. Defective pressure switch
continuously
2. Excessive air usage
3. Check valve leaking
Compressor vibrates Loose mounting bolts
Air output lower 1. Broken inlet valves
than normal
2. Intake filter dirty
3. Connections leaking
2. Wrong gauge wire or length of
extension cord.
3. Clogged air filter.
4. Lack of proper ventilation.
The motor must be
allowed to cool down
before start-up is possible. The motor will
automatically restart without warning if
left plugged into electrical outlet, if the
motor is turned on.
corrective action
1. Check for proper use of extension cord (see EXTENSION CORDS,
page 5)
2. Plugged in? Check fuse/breaker or motor overload
3. Replace blown fuse in household circuit
4. Reset, determining why problem happened
5. Motor will restart when cool; turn off compressor and wait 20
minutes.
6. Replace
1. Check with voltmeter
2. Check gauge chart, under Installation for proper gauge wire and
cord length
3. Replace motor
4. Replace or repair
1. Check for proper fuse, use time-delay fuse. Disconnect other
electrical appliances from circuit or operate compressor on its
own branch circuit
2. Check gauge chart, under Installation
3. Replace or repair
1. Check with voltmeter
2. Clean filter (see Maintenance section)
3. Move compressor to well ventilated area
4. Check gauge chart, under Installation
1. Check all connections with soap and water solution and tighten
2. Tighten
3. Disassemble check valve assembly, clean or replace
1. Drain receiver
2. Move to area of less humidity; use air line filter
1. Replace switch
2. Decrease air usage; compressor not large enough for a
requirement
3. Disassemble check valve assembly, clean or replace
Tighten
1. Have authorized service representative repair unit
2. Clean or replace intake filter
3. Tighten connections

StoraGe
1. When not in use, hose and
compressor should be stored in a
cool dry place.
2. Tank should be drained of moisture.
3. Hose should be disconnected and
hung open ends down to allow any
moisture to drain.
Do not disassemble check valve
with air in tank; bleed tank first.
