Troubleshooting Guide _The air compressor should be turned off and unplugged from the power source before any mamtenanse is performed as well as the _Jr bted from the tank and the unut allowed time to cool Persona] inluries could occur from moving pans, _[ectrica] sources, compressed anr,or hot surfaces PROBLEM POSglBLE CORRECTION Air leaks at the check valve A defective chsok valve results in s constant air leak at the pressure relief valve or st the pressure relief valve, when there is pressure in the tank and the compressor is shut off. Drain the tank, then remove and clean or replace the check valve Air leaks between head and Be sum of proper torque on head bolts. If leak rem,_ins,contact a servicetsohnician. cylinder. Anrleek from safety valve. Operate the safety valve manually by pulling on the dng, If the valve continues to leak when in the closed posibon, tt should be replaced. Pressure msding on the regulated pressure gauge dreps whenanecoeseory_e used. Excessive tank pressure. Motor will not e_aR, Excessive moisture _rt the discharge sir. Air leaks from the tank body ortank welds If there us an excessive amount of pressure drop when the accessory ns used, replase the regulator. NOTE: Adjust the regulated pressure under flow conditions(while accessory is being used). It is normal for the gauge to show minimal pressure loss dudng _niUal use of the tool, Move the Auto-On/Off lever to the Off position. If the unit doesn't shut off, unplug it from the power source end contact a service technician, Make sure power cord is plugged In and the switch is on. inspect for the proper size rues in your circuit box. If the fuse was tnpped, reset Pl and restart the unnt. If repeated tripping occurs, replace the check valve or contact a service technician, Remove the water in the tank by draining after each usa. High humidity environments will cause excessive condensation Utilize water/llter_ on your air line. NOTE: Water condensationis not caused by compressorma]functnon. Be sure the compreseor's slr output is greater then your tool's anr coneumptfonrate.
