3. Place a suitable oil drain pan below oil drain plug (see Fig. 4). 11 Weekly: • Inspect and clean air filter. • Clean breather holes on oil fill plug. Monthly: • Check for air leaks.+ • Check safety relief valve. Six months or 200 operating hours:* • Change compressor oil. Use only SAE 30 weight non-detergent air compressor oil. • Replace oil more frequently when used in dusty operating environments. 4. Remove oil fill breather plug to allow air to enter crankcase. 5. Remove oil drain plug. 6. Allow oil to drain completely. Tilt air compressor towards the oil drain to assist draining. 7. Clean and replace oil drain plug. 8. Refill crankcase with SAE 30 weight non-detergent air compressor oil until the oil level reaches the center of the red circle in the oil level sight glass. Be careful not to overfill. 9. Reinstall the oil fill breather plug. CHECKING SAFETY RELIEF VALVE: SAFETY RELIEF VALVE MUST BE REPLACED IF IT CANNOT BE ACTUATED OR IT LEAKS AIR AFTER THE RING IS RELEASED. 1. The air compressor must be turned OFF. 2. Disconnect compressor from the power source. 3. Open tank drain to bleed off all air pressure before attempting any maintenance or repair. 4. Allow compressor to fully cool before attempting any maintenance or repair. 5. Grasp the wire ring on the safety relief valve. 6. Pull and release the ring a few times to ensure that the plunger moves in and out. Replace the safety relief valve if plunger does not move or is difficult to move. CHECKING AIR FILTER ELEMENT: 1. The air compressor must be turned OFF. 2. Disconnect compressor from the power source. 3. Open tank drain to bleed off all air pressure before attempting any maintenance or repair. 4. Allow compressor to fully cool before attempting any maintenance or repair. 5. Remove the face of the filter body to access the filter element by pushing and rotating the front portion of the filter body in a counter clockwise direction to release the locking tabs. 6. Use compressed air to blow loose dirt and debris from the paper filter element. Replace filter element if it cannot be cleaned sufficiently. 7. Reinsert filter element into filter body and reinstall filter faceplate. MOISTURE IN COMPRESSED AIR Moisture is a normal by-product of compressing air. As the moisture builds during compressor use, it can be carried though the air hose. When using paint spray gun or sandblasting gun, the use of a special filter to remove moisture from the air line is highly recommended. Moisture in the compressed air will cause water spots in paint jobs and cause blasting media to clog the sandblasting gun. 12 Fig. 4 13 TROUBLESHOOTING GUIDE Problem Encountered Possible Cause Possible Solution The compressor does not start or restart: Power cord not plugged in. Plug cord into grounded outlet. Motor/Pressure switch in OFF position Move switch to AUTO position. Motor thermal overload switch has tripped. Turn air compressor off, wait until the motor is cool, then press motor thermal overload (red) button firmly until click is heard. Fuse blown or circuit breaker has tripped. Replace fuse or reset circuit breaker. Check for proper fuse amperage. Check for low voltage conditions. Disconnect any other electrical appliances from circuit or operate air compressor on its own branch circuit. Wrong gauge wire or length of extension cord. Check chart in instruction manual for proper gauge wire and cord length. Air tank pressure exceeds motor/pressure switch "cut-in" pressure. Motor will start automatically when air tank pressure drops below "cut-in" pressure of motor/pressure switch. Pressure release valve on motor/pressure switch has not unloaded pump head pressure. Bleed the line by moving the switch to the OFF position. Defective motor, motor capacitor, motor/pressure switch. Contact Consumer Helpline at 1-800-423-3598. The compressor motor stalls: Overloaded motor. Have a certified electrician check the motor and wiring. Proceed with his or her recommendations. Improper lubrication. See LUBRICATION section in instruction manual. Low oil level. Check oil level and fill if necessary. Defective check valve. Replace check valve. Excessively noisy operation: Loose motor pulley or pump flywheel. Tighten pulley and/or flywheel (where applicable). Lack of oil in the pump crankcase. Check oil level. If low, check for possible bearing damage. Add correct amount of oil. Carbon deposits on pistons or valves. Remove cylinder head and inspect. Clean or replace parts as needed. Bearing, piston or connecting rod failure. STOP THE COMPRESSOR! Contact Consumer Helpline at 1-800-423-3598. Worn connecting rod. Replace with new connecting rod. Worn piston wrist pin bushing. Remove piston/connecting rod assembly from the compressor and inspect for excess wear. Replace worn parts as needed. Worn bearings. Replace worn bearings as needed. NOTE: Dirty oil can cause accelerated wear. Change oil frequently using recommended oil. Noisy check valve. Replace check valve. When in the Start/Stop op...
