Automatic Shut off System

1.  If the Compressor automatically shuts off 

before reaching its normal cutoff pressure:
a.  Shut off all tools.
b.  Turn Power Switch OFF.
c.  Unplug Compressor.
d.  Wait until the Compressor cools down 

(about 10 minutes);

e.  Plug in Compressor.
f.  Turn Power Switch ON (AUTO).
g.  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.  Turning Air Compressor off and 

on again too quickly.

3.  Correct any issues before further use to 

avoid damage to the compressor.
