8. Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise). 9. Replace the pressure release tube. Tighten nuts. 10. Replace the outlet tube and tighten nuts. 11. Perform the Break-in Procedure. See “Break-in Procedure” in the Operation section. D26161 20-ENG Motor This motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart: 1. Place the On/Auto/Off lever in the Off position. 2. Allow the motor to cool. 3. Depress the red reset button on the motor. Reset Button 4. Place the On/Auto/Off lever in the On/Auto postion to restart the motor. IMPORTANT: If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when: 1. The motor does not get up to full power or speed. 2. Fuses blow out when starting the motor; lights dim and remain dim when motor is started and is running. Additional Service Disassembly or service of the air compressor beyond what is covered in this manual is not recommended. If additional service is required, contact your nearest Authorized Warranty Service Center. STORAGE Before you store the air compressor, make sure you do the following: 1. Review the “Maintenance” section on the preceding pages and perform scheduled maintenance as necessary. 2. Set the On/Auto/Off lever to “OFF”. 3. Close the globe valve. 4. Remove the air tool or accessory. 5. Open the globe valve and allow the air to slowly bleed from the air tank until tank pressure is approximately 20 psi. 6. Drain water from air tank by opening drain valve (counterclockwise) on bottom of 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. 7. After the water has been drained, close the drain or drain valve. NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. 8. Protect the air hose from damage (such as being stepped on or run over). 21-ENG D26161 TROUBLESHOOTING Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or compressd air sources. Personal injury may occur. Prior to attempting any repairs, unplug the air compressor and bleed off all air tank air pressure.
