Operating Instructions
Troubleshooting Chart
Symptom
Compressor will not run
Motor hums but cannot
run or runs slowly
Fuses blow/circuit
breaker trips repeatedly
Thermal overload
protector cuts out
repeatedly
Tank pressure drops
when compressor shuts
off
Excessive moisture in
discharge air
Compressor runs
continuously
Compressor vibrates
Compressor "walks" on
hard surfaces
Air output lower than
normal
Possible Cause(s)
1. Loss of power or overheating
2. No electrical power
3. Blown fuse
4. Breaker open
5. Thermal overload open
6. Pressure switch bad
1. Low voltage
2. Wrong gauge wire or length of
extension cord
3. Shorted or open motor winding
4. Defective check valve or unloader
5. Unit is cold, oil too thick
6. Low oil level
7. Defective capacitor
1. Incorrect size fuse, circuit overloaded
2. Wrong gauge wire or length of
extension cord
3. Defective check valve or unloader
4. Low oil level
1. Low voltage
2. Clogged air filter
3. Lack of proper ventilation/room
temperature too high
4. Wrong gauge wire or length of
extension cord
5. Low oil level
1. Loose connections (fittings, tubing, etc.)
2. Loose drain lock
3. Check valve leaking
1. Excessive water in air receiver
2. High humidity
1. Defective pressure switch
2. Excessive air usage
3. Air leak
Loose mounting bolts
Foot mounting bolts not securely
tightened
1. Broken valves
2. Intake filter dirty
3. Connections leaking
Corrective Action
1. Check for proper use of extension cord (see EXTENSION
CORDS, page 3)
2. Plugged in? Check fuse/breaker
3. Replace blown fuse
4. Reset. Determine why problem happened
5. Motor will restart when cool
6. Replace
1. Check with voltmeter
2. Check gauge chart under Operation for proper gauge
wire and cord length
3. Replace motor
4. Replace or repair
5. Use 5W-30 synthetic (Mobil 1) and/or warm up the unit
6. Add oil to full line on dipstick
7. Replace or repair
1. Check for proper fuse, use time-delay fuse. Disconnect
other electrical appliances from circuit or operate
compressor on dedicated branch circuit
2. Check gauge chart, under Operation
3. Replace or repair
4. Add oil to full line on dipstick
1. Check with voltmeter
2. Clean filter (see Maintenance section)
3. Move compressor to well ventilated area
4. Check gauge chart, under Operation
5. Add oil to full line on dipstick
1. Check all connections with soap and water solution and
tighten
2. Tighten
3. Disassemble check valve assembly, clean or replace
DANGER
!
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 air
requirement
3. Repair or replace leaking component
Tighten pump mounting bolts so rubber washer is
slightly compressed
Tighten foot mounting bolts underneath tank assembly
1. Have authorized service representative repair unit
2. Clean or replace intake filter
3. Tighten connections
7
Do not disassemble check valve
with air in tank; bleed tank
