RECOMMENDED 
HOOKUP

MINIMUM COMPONENTS 

REQUIRED FOR HOOKUP

Air  compressor:

  The  air  compressor  must  be  able  to 

maintain  a  minimum  of  70PSI  when  the  nailer is being 

used. An inadequate air supply can cause a loss of power 

and inconsistent driving.
Pressure  regulator:   A  pressure  regulator  is  required  to 

control the operating pressure of the nailer between 70PSI 

and 110PSI .

  Always  use  air  supply  hoses  with  a 

minimum working pressure rating equal to or greater than 

the pressure from the power source, or 150PSI, whichever 

is greater. Use 1/4 inch air hose for runs up to 50 feet. Use 

3/8 inch air hose for 50 feet, run or longer.

Air  supply  hose:

HOOKUP INSTRUCTIONS FOR 

TOOL TO AIR SUPPLY

For better  performance, install  a 3/8 inch quick plug(1/4 

inch NPT threads) with an inside diameter of 0.315 inch 

(8mm) on the nailer and a 3/8 inch quick coupler on the air 

hose.

With ON/OFF switch in OFF position, plug compressor 

into electrical outlet.

Close pressure regulator by turning all the way to the 

left. Turn compressor ON and let it pump all the way up 

1.

2.

to automatic shut-off pressure.

Attach  air  hose  to  regulator  outlet.  Adjust  pressure 

regulator by turning to the right so that outlet pressure is 

between 70PSI to 110PSI.

Load fasteners into nailer.

Point the nailer in a safe direction while attaching to air 

hose.

Nailer is ready for use. You may need to adjust outlet 

pressure to achieve proper fastener depth.
