Turn unit off, wait 5 minutes, then press Motor Thermal Overload until click is heard. Reset circuit breaker or replace fuseif necessary, using only "Fusetron" type T fuses. Check for low voltage conditions. Disconnect any other electrical appliances from circuit or operate aircompressor on its own branch circuit. Add oil. (See page 9 or 11) Use additional air hose instead of extension cord, or use proper wiregauge and cord length. (See page12) Contact your Customer Service. When Pilot Valve is set in the Start/ Stop position, motor will start automatically when air tank pressuredrops down to the "Cut-in" or "Start" pressure of the Motor/PressureSwitch. Bleed the line by moving the switchto the "Off" position. Remove and clean or replace. Contact your Customer Service. Use additional air hose instead of extension cord, or use proper wiregauge and cord length. (See page12) Contact qualified electrician. Move unit to well ventilated area. Use lighter weight oil. (See pg. 9 or11) Use another circuit or remove excess appliances from circuit. Contact qualified electrician. Replace. Air compressor does not stop Motor/Pressure Switch not operat-Replace. even though the maximum ing correctly. pressure allowed has beenreached. Portable Electric Air Compressor Manual TROUBLESHOOTING SYMPTOM Noisy operation. PROBABLE CAUSE Loose motor pulley or pump flywheel. REMEDY Tighten pulley and or flywheel. Lack of oil in the pump. Carbon deposits on pistons or valves. Bearing, piston or connecting rodfailure. Add correct amount of oil. Check for bearing damage. Remove cylinder head and inspect. Clean or replace valve plate. STOP THE AIR COMPRESSOR! Contact your Manufacturer CustomerService. Pressure drop in air tank or rapid pressure loss when air compressor is shut off. Air leaks at connections. Defective Check Valve or Pilot Valve. Allow the air compressor to buildpressure to the maximum allowed. Turn off and brush a soapy water solution onto all connections. Check connections for air bubbles. Tighten the connections where leaks are present. Remove, clean or replace. Air leak in air tank. Air tank must be replaced. Do not attempt to repair air tank! Insufficient pressure at air tool or accessory. Air leaks or restrictions. Restricted air intake filter. Hose or hose connections are too small or long. Air compressor is not large enough for air requirement. Pressure Regulator not turned to high enough pressure or defective. Slipping belt. Restricted Pilot Valve. Check for leaks and repair. Clean or replace. Replace with larger hose or connectors. Use a smaller tool or larger air compressor. Adjust Pressure Regulator to proper setting or replace. Tighten or replace. Clean or replace. Air leaks from Safety Relief Valve. Possible defective Safety Relief Valve. Operate Safety Relief Valve manually by pulling on ring. If it still leaks, it should be replaced. Excessive air tank pressure. Replace Motor/Pressure Switch. Clean, reset or replace Pilot Valve. Air leaks at pump. Air continues to leak at Motor/ Pressure Switch while motor is running. Air blowing from Air Intake Filter. Defective gaskets. Defective Motor/Pressure Switch. Damaged inlet (reed) valve. Torque head bolts: Single Stage= 17 ft./lbs. Two Stage= 33 ft./lbs. Replace. Replace. Portable Electric Air Compressor Manual TROUBLESHOOTING SYMPTOM PROBABLE CAUSE REMEDY When in the Start/Stop Option, Motor/Pressure Switch does not motor runs continuously. shut off motor when air compressor reaches "cut-out" pressure and safety relief valve activates. Air compressor is incorrectly sized. Move the Motor/Pressure Switch to the "OFF" position. If the motor does not shut off, unplug the air compressor. If the electrical contacts are welded together, replace the pressure switch. Limit the air pressure to the capacity of the air compressor. Either use a smaller tool or a larger air compressor. Moisture in discharge air. Condensation in air tank caused by high level of atmospheric humidity. Run air compressor a minimum ofone hour to prevent condensationbuildup. Drain air tank after every use. Drain air tank more often in humid weather and use an air line filter. Excessive oil consumption or oil in hose. Restricted air intake filter. Air compressor on unlevel surface. Crankcase overfilled with oil. Wrong viscosity. Plugged oil dipstick vent. Oil leaks. Worn piston rings or scored cylinder. Clean or replace. Do not incline the air compressor more than 10° in any direction while running. Drain oil. Refill to proper level with SAE-30W non-detergent oil. Drain oil. Refill to proper level with SAE-30W non-detergent oil. Clean. Tighten pump bolts to torque stated in Parts List, or replace gaskets. Contact your Customer Service. Oil has milky appearance. Water in oil due to condensation. Change oil and move aircompressor to a less humid environment. Unit runs backward. Reversed wiring. Contact qualified electrician.
