change to the automatic pressure 

levels may cause excess pressure 

to accumulate, causing a hazardous 

situation.

11.  Adjust the Air Compressor’s Pressure 

Regulator (85) so that the air output 

is enough to properly power the tool, 

but the output will not exceed the 

tool’s maximum air pressure at any 

time.  Turn the knob clockwise to 

increase the pressure and counter-

clockwise to decrease pressure.  

Adjust the pressure gradually, while 

checking the air output gauge to set 

the pressure.

12.  Use the air tool as needed.
13.  After the job is complete, turn the 

Power Lever OFF.

14.  Unplug the Air Compressor.
15.  Close the in-line Shutoff Valve.
16.  Bleed air from the tool then 

disconnect the tool.

17.  Turn the Drain Valve (71), at the 

bottom of the Tank, counterclockwise 

to release any built-up moisture and 

the internal tank pressure.  Close the 

valve after moisture has drained out.  

Do not remove the Drain Valve.

18.  Clean, then store the Air Compressor 

indoors.

Emergency Depressurization

If it is necessary to quickly 

depressurize

 the Compressor, turn  

the Power Lever OFF.  Then, pull on 

the ring on the Safety Valve (64) to 

quickly release stored air pressure.

Automatic Shut off System

1. 

Reset 

Button

Figure 4

If the Compressor automatically   

shuts off, or hums then shuts off:

a. Shut off all tools.
b. Wait until the Compressor cools 

down (about 10 minutes);

c. 

If the unit does not start up again 

on it’s own, press the Reset 

Button to start the compressor

;

d. Resume operation.

2.  Possible causes of repeated 

automatic shut off of the compressor 

are:

a. Using an extension cord that is too 

long or narrow;

b. An air leak or open hose causing the 

compressor to cycle too often and 

build up heat. 

c. Incorrect oil type for the ambient 

working conditions.

3.  Correct any issues before further use 

to avoid damage to the compressor.
