air hose is ruptured.  The shutoff 

valve should be a ball valve because 

it can be closed quickly.  See pages 8 

and 9 for Air Tool Setup procedures.

Note: 

If an automatic oiler system is not 

used, add a few drops of Pneumatic 

Tool Oil into the airline connection before 

operation.  Add a few more drops after 

each hour of continual use.

2.  Attach an air hose to the compressor’s 

air outlet.  Connect the air hose to the  

air inlet of the tool.  

Please note:

 a  

quick coupler will be needed for  

proper connection.

WARNING!  TO PREVENT SERIOUS 

INJURY FROM ACCIDENTAL 

OPERATION: Do not install a quick 

coupler on the tool.

  A coupler contains 

an air valve that will allow the air tool to 

retain pressure and operate accidentally 

after the air supply is disconnected.

Note: 

Air flow, and therefore tool 

performance, can be hindered by 

undersized air supply components.

3.  The air hose must be long enough 

to reach the work area with enough 

extra length to allow free movement 

while working.

4.  Release the tool’s Trigger (44).
5.  Close the in-line safety valve between 

the compressor and the tool.

6.  Turn on the air compressor according to 

the manufacturer’s directions and allow it 

to build up pressure until it cycles off.

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 exceed 

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 supply, 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.

Nail Penetration Depth Adjustment

1.  With the tool connected to its air supply 

and with the nails loaded, test fire on a 

scrap material (similar to the workpiece) 

and note the depth of nail’s penetration.

2.  To adjust nail depth penetration, rotate 

the Depth Knob (52). Turn the Depth 

Knob to the left (+) for deeper nail 

penetration and to the right (-) for more 

shallow penetration.

3. 

CAUTION! 

 When working with asphalt 

shingles in particular, the nail head 

should not sink below the top face of  

the shingle.
