7.  Adjust the air compressor’s output 

regulator 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.  Adjust the pressure gradually, 

while checking the air output gauge 

to set the right pressure range.

8.  The air pressure setting must not ex-

ceed job site regulations/restrictions. 

The air pressure setting must not 

exceed 90 PSI when being used with 

work pieces that have a thickness of 

less than 1-3/4”.

9.  Inspect the air connections for leaks.  

Repair any leaks found.

10.  If the tool will not be used at this 

time, turn off and detach the air sup-

ply, safely discharge any residual air 

pressure, and release the trigger to 

prevent accidental operation.

Note:

  Residual air pressure should not be 

present after the tool is disconnected 

from the air supply.  However, it is a 

good safety measure to attempt to 

discharge the tool in a safe fashion 

after disconnecting to ensure that the 

tool is disconnected and unpowered.

OPERATING INSTRUCTIONS

  Read the ENTIRE IMPORTANT 

SAFETY INFORMATION 

section at the beginning of this 

manual including all text under 

subheadings therein before set 

up or use of this product.
Inspect tool before use, looking 

for damaged, loose, and 

missing parts.  If any problems 

are found, do not use tool until 

repaired.

Work Piece and Work Area Set Up

1.  Designate a work area that is clean 

and well-lit.  The work area must not 

allow access by children or pets to 

prevent injury and distraction.

2.  Route the air hose along a safe route 

to reach the work area without creat-

ing a tripping hazard or exposing the 

air hose to possible damage.  The air 

hose must be long enough to reach 

the work area with enough extra 

length to allow free movement while 

working.

3.  Secure loose workpieces using a vise 

or clamps (not included) to prevent 

movement while working.

4.  There must not be hazardous ob-

jects (such as utility lines or foreign 

objects) nearby that will present a 

hazard while working.

Testing the Full Sequential Safety 

Trip Mechanism

 

TO PREVENT 

SERIOUS INJURY 

FROM ACCIDENTAL 

OPERATION: 

Empty the tool before this 

procedure.  Point the tool at a 

piece of scrap wood when 

testing.

The Tool should not fire if the nose 

is not depressed against the workpiece. 

This tool has a full sequential safety trip 

mechanism, which is designed to prevent 

inadvertent firing. The tool will only fire if 

the Safety is resting on the workpiece prior 

to pulling the Trigger.
