manual abstract
The compressor is now ready for use. 8 — ENG OPERATING PROCEDURES 1. Before attaching air hose or accessories, make sure the OFF/AUTO lever is set to “OFF” and the air regulator or shut-off valve is closed. 2. Attach hose and accessories. TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS RISK OF BURSTING. CHECK THE MANUFACTURER'S MAXIMUM PRESSURE RATING FOR AIR TOOLS AND ACCESSORIES. THE REGULATOR OUTLET PRESSURE MUST NEVER EXCEED THE MAXIMUM PRESSURE RATING. 3. Turn the OFF/AUTO lever to “AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure. 4. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. Your compressor is ready for use. 5. Always operate the air compressor in well-ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the spray area. When you are finished: 6. Set the “OFF/AUTO” lever to “OFF”. 7. Turn the regulator counterclockwise and set the outlet pressure to zero. 8. Remove the air tool or accessory. 9. Open the regulator and allow the air to slowly bleed from the tank. Close the regulator when tank pressure is approximately 20 psi. 10. Drain water from air tank. WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE. NOTE If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. 11. After the water has been drained, close the drain cock or drain valve. The air compressor can now be stored. 9 — ENG TROUBLESHOOTING GUIDE PERFORMING REPAIRS MAY EXPOSE VOLTAGE SOURCES, MOVING PARTS OR COMPRESSED AIR SOURCES. PERSONAL INJURY MAY OCCUR. PRIOR TO ATTEMPTING ANY REPAIRS, UNPLUG THE COMPRESSOR AND BLEED OFF TANK AIR PRESSURE. PROBLEM CAUSE CORRECTION Excessive tank pressure safety valve pops off. Pressure switch does not shut off motor when compressor reaches “cutout” pressure. Pressure '"cut-out" too high. Move the pressure switch lever to the “OFF” position. If the outfit doesn’t shut off, unplug. If the electrical contacts are welded together, replace the pressure switch. Return the outfit to an authorized dealer to check and adjust, or replace switch. Air leaks at fittings. Tube fittings are not tight enough. Tighten fittings where air can be heard escaping. Check fittings with soapy water solution. DO NOT OVER-TIGHTEN. Air leaks at or inside check valve. Defective or dirty check valve. A defective check valve results in a constant air leak at the pressure release valve when there is pressure in the tank and the compressor is shut off. Remove and clean or replace check valve. DO NOT OVERTIGHTEN. Air leaks at pressure switch release valve. Defective pressure release valve. Defective check valve. Remove and replace the release valve. A defective check valve results in a constant air leak at the pressure release valve when there is pressure in the tank and the compressor is shut off. Remove and clean or replace check valve. DO NOT OVERTIGHTEN. Air leaks in air tank or at air tank welds. Defective air tank. DO NOT DRILL INTO, WELD OR OTHERWISE MODIFY AIR TANK OR IT WILL WEAKEN. THE TANK CAN RUPTURE OR EXPLODE. Air tank must be replaced. Do not repair the leak. Pressure reading on the regulated pressure gauge drops when an accessory is used. It is normal for “some” pressure drop to occur. If there is an excessive amount of pressure drop when the accessory is used, adjust the regulator following the instructions on page 7. NOTE Adjust the regulated pressure under flow conditions (while accessory is being used). 10 — ENG TROUBLESHOOTING GUIDE (Continued) PROBLEM CAUSE CORRECTION Air leak from safety valve. Possible defect in safety valve. Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced. Knocking Noise Defective check valve. Remove and clean, or replace. Compressor is not supplying enough air to operate accessories. Prolonged excessive use of air. Compressor is not large enough for air requirement. Decrease amount of air usage. Check the accessory air requirement. If it is higher than the SCFM or pressure supplied by your air compressor, you need a larger compressor. Hole in hose. Air leaks. Check valve restricted. Remove and clean, or replace. Tighten fittings. (See Air Leaks Section of Troubleshooting Guide.) Check and replace. Motor will not run. Tank pressure exceeds pressure switch “cut-in” pressure. Wrong gauge wire or length of extension cord. Loose electrical connections. Check valve stuck open. Paint spray on internal motor parts. Possible defective motor. Fuse blown, circuit breaker tripped. Motor will start automatically when tank pressure drops below “cut-in” pressure of pressure switch. Check for proper gauge wire and cord length. Check wiring connection inside pressure switch and terminal box area. Remove and clean, or replace. Have checked at an Authorized Warranty Service Center. Do not op...
