Symptom	Possible Causes	Corrective Action
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

Compressor is not supplying enough air to operate accessories

1.	Prolonged excessive use of air	1.	Decrease amount of air usage
2.	Compressor is not large enough for air	2.	Check the accessory air requirement. If it
	requirement		is higher than the SCFM or pressure
			supplied by your air compressor, you
			need a larger compressor
3.	Restricted air intake filter	3.	Clean or replace air intake filter. Do not
			operate the air compressor in apaint
			spray area
4.	Hole in hose	4.	Check and replace if required
5.	Check valve restricted	5.	Remove and clean or replace
6.	Air leaks	6.	Tighten fittings (See Air Leaks Section of
			Troubleshooting Chart)

Motor will not run	1.	Motor overload protection switch has
		tripped
	2.	Tank pressure exceeds pressure switch
		"cut-in" pressure
	3.	Wrong gauge wire or length of
		extension cord
	4.	Check valve stuck open
	5.	Loose electrical connections
	6.	Paint spray on internal motor parts

7. Possible defective motor

8. Fuse blown, circuit breaker tripped

1.Let motor cool off and overload switch will automatically reset

2.Motor will start automatically when tank pressure drops below "cut-in" pressure of pressure switch

3.Check for proper gauge wire and cord length

4.Remove and clean or replace

5.Check wiring connection inside pressure switch and terminal box area

6.Have checked at Service Center. Do not operate the compressor in the paint spray area. See flammable vapor warning on page 2

7.Have checked at local Service Center

8.a. Check fuse box for blown fuse and replace if necessary. Re-set circuit breaker. Do not use a fuse or circuit breaker with higher rating than that specified for your partiular branch circuit

b.Check for proper fuse; only "Fusetron" Type T fuses are acceptable

c.Check for low voltage conditions and/or proper extension cord

d.Disconnect the other electrical appliances from circuit or operate the compressor on its own branch circuit

9. Pressure release valve on pressure	9. Bleed the line by pushing the lever on
switch has not unloaded head pressure	the pressure switch to the OFF position;
	if the valve does not open, replace it
