Tire Inflation Gun

OPERATION INSTRUCTIONS:

This air compressor comes with  1/4” quick connect 
stud. An extension coil hose and a tire inflation gun 
are also included with your compressor. Each end of 
the extension coil hose is equipped with a 1/4” quick 
connect coupler. The tire inflation gun comes with a 
1/4”   quick   connect   stud,   pressure   gauge,   rubber 
hose, bleeder valve and tire chuck. Attach one end of 
the   extension   coil   hose   to   the   stud   on   your 
compressor and the other end to the stud on the tire 
gun kit. The tire gun kit can be used for both airing 
up and airing down. Please familiarize yourself with 
the following functions of this versatile air tool:

A.   TIRE INFLATION:

1.

Attach one end of the extension coil hose to the 
compressor and the other end to the tire gun kit. 

2.

Push the tire chuck, with the lever in the upright 
position, down over the tire valve stem and then 
push the lever down to the horizontal position to 
lock in place. 

3.

Turn compressor switch on and  hold down the 
trigger on the tire gun kit to begin inflation. 

4.

When   desired   pressure   is   reached,   release   the 
trigger and turn power switch on compressor off. 

Note:   Your   air   compressor   is   equipped   with   a 
pressure switch (cut in at 120psi, cut out at 145psi). 
This   feature   is   designed   to   protect   the   air 
compressor   from   over-pressure   causing   permanent 
damage to your air compressor. The pressure switch 
automatically  turns off  the motor when  the internal 
pressure of the air compressor reaches the factory 
set “cut-out” pressure (145psi) and restarts when the 
internal pressure drops below 120psi.

B.   TIRE DEFLATION:

1.

Push the tire chuck (with the lever in the upright 
position) down over the tire valve stem and then 
push the lever down to the horizontal position to 
lock in place. 

2.

Press the bleeder valve button on the tire gun kit 
to decrease tire pressure. 

3.

When   desired   pressure   if   reached,   release   the 
bleeder valve button to halt deflation. 

C.   INLINE PRESSURE GAUGE:

1.

The pressure gauge on the inflation gun provides 
convenient tire pressure monitoring when airing 
up or down (not airflow of the compressor). This 
eliminates   switching   back   and   forth   between   a 
tire chuck and a tire pressure gauge. 

2.

Please   note   that   during   inflation   and   deflation, 

due   to   air   velocity,   pressure   gauge   cannot 

provide   accurate   pressure   readings.   Release 

lever on the tire inflation gun during inflation to 

check tire air pressure. 

NOTE:  To   release   excess   pressure,   turn   off 
compressor and disconnect hose from compressor. 
With the tire inflation gun still connected to the other 
end of the coil hose, pull trigger on the tire inflation 
gun to release excess pressure
