Air leaks at or Check valve seat damaged. A defective check valve inside check results in a constant air leak valve at the pressure release valve when there is pressure in the tank and the compressor is shut off. Replace check valve. Refer to the “To Replace or Clean Check Valve” in the “Service and Adjustment” section. Air leaks at pressure switch release valve. Defective pressure switch release valve.

Do not drill into, weld or otherwise modify air tank or it will weaken. The tank can rupture or explode. Air leaks between head and valve plate. Leaking seal. Contact a Trained Service Technician. 21- ENG D26368 PROBLEM CAUSE CORRECTION 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 in the “Description of Operation” paragraph in the “Operation Section. NOTE: Adjust the regulated pressure under flow conditions (while accessory is being used). Knocking Noise. Possible defect in safety valve. Defective check valve. Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced. Remove and clean, or replace. Compressor is Prolonged excessive use of Decrease amount of air not supplying air. usage. enough air to operate Compressor is not large Check the accessory air accessories. enough for air requirement. Hole in hose. Check valve restricted. Air leaks. Restricted air intake filter requirement. If it is higher than the SCFM or pressure supplied by your air compressor, you need a larger compressor. Check and replace if required. Remove and clean, or replace. Tighten fittings. Clean or replace air intake filter. Do not operate the air compressor with the filter removed. Refer to the “Air Filter” paragraph in the “Maintenance “ section. Regulator knob has continuous air leak. Damaged regulator Replace D26368 22- ENG PROBLEM CAUSE CORRECTION Regulator will not shut off air outlet. Damaged regulator Replace Motor will not Motor overload protection Let motor cool off and run. Fuse blown, circuit breaker tripped. switch has tripped Tank pressure exceeds pressure switch “cut-in” pressure. Extension cord is wrong length or gauge. Loose electrical connections. Check valve stuck open. Possible defective motor or starting capacitor. Paint spray on internal motor parts. Pressure release valve on pressure switch has not unloaded head pressure. 1. 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. You should use 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. overload switch will automatically reset. 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. Have checked by a Trained Service Technician. Remove and clean, or replace. Have checked by a Trained Service Technician. Do not operate the compressor in the paint spray area. See flammable vapor warning. Bleed the line by pushing the lever on the pressure switch to the “off” position; if the valve does not open, replace switch. 23- ENG D26368 LIMITED WARRANTY DeVilbiss Air Power Company warrants to the original purchaser who uses the product in a consumer application (personal, residential or household usage) that all products covered under this warranty are free from defects in material and workmanship for one year from the date of purchase.
