1Pressure switch does not shut off motor when compressor reaches cut-out pressureSet the On/Off switch to OFF, if the unit does not shut off contact an authorized service center.
2Pressure switch cut-out too highContact an authorized service center.
3Tube fittings are not tight enoughTighten fittings where air can be heard escaping. Check fittings with soapy water solution. Do Not Overtighten.
4Defective air tankAir tank must be replaced. Do not repair the leak.
A WARNING: Risk of bursting. Do not drill into, weld or otherwise modify air tank or it will weaken. The air tank can rupture or explode.
5Leaking sealsContact an authorized service center.
6Defective safety valveOperate safety valve manually by pulling on ring. If valve still leaks, it must be replaced.
7Regulator is not adjusted correctly for accessory being usedIt is normal for some pressure drop to occur when an accessory is used, adjust the regulator as instructed in Regulator under Features if pressure drop is excessive.
NOTE: Adjust the regulated pressure under flow conditions while accessory is being used.
8Prolonged excessive use of airDecrease amount of air usage.
9Compressor is not large enough for accessoryCheck the accessory air requirement. If it is higher than the SCFM or pressure supplied by air compressor, a larger compressor is needed to operate accessory.
10Hole in air hoseReplace air hose.
11Check valve restrictedRemove, clean or replace.
12Air leaksTighten fittings.
13Regulator is damagedReplace.
14Unit operating in damp or humid conditionsMove unit to a dry well ventilated area
15Restricted air intake filterClean or replace air intake filter
16Pump oil is lowAdd ISO 100/SAE40, non-detergent, premium air compressor oil to pump.
17Carbon build-up in pump.Contact an authorized service center.
18Detergent type oil being used in pumpDrain oil and refill pump with ISO 100/SAE40, non-detergent, premium air compressor oil.
19Motor overload protection switch has tripped
20Extension cord is wrong length or gaugeCheck for proper gauge wire and cord length.
21Loose electrical connectionsContact an authorized service center.
22Possible defective motor or starting capacitor
23Paint spray on internal motor partsContact an authorized service center. Do not operate the compressor in the paint spray area.
24Fuse blown, circuit breaker tripped1. Check fuse box for blown fuse and replace as necessary. Reset circuit breaker. Do not use a fuse or circuit breaker with higher rating than that specified for your particular branch circuit.
2. Check for proper fuse. Use only a time delay fuse.
3. Check for low voltage conditions and/or proper extension cord.
4. Disconnect the other electrical appliances from circuit or operate the compressor on its own branch circuit.
25Tank pressure exceeds pressure switch cut-in pressureMotor will start automatically when tank pressure drops below cut-in pressure of pressure switch.
26Pressure release valve on pressure switch has not unloaded head pressureSet the On/Off switch to OFF. If the valve does not open, replace switch. Contact an authorized service center.
