while checking the air output gauge 

to set the right pressure range.

8.  Inspect the air connections for leaks.  

Repair any leaks found.

9.  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 throttle and/or turn the switch to 

its off position to prevent accidental 

operation.

10.  Drain the compressor regularly.

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.

Tool Set Up

 

TO PREVENT 

SERIOUS INJURY 

FROM ACCIDENTAL 

OPERATION: 

Turn off the tool, detach the 

air supply, safely discharge 

any residual air pressure in 

the tool, and release the 

Trigger before performing any 

inspection, maintenance, or 

cleaning procedures.
TO PREVENT SERIOUS 

INJURY: 

Do not adjust or tamper with 

any control or component in a 

way not specifically explained 

within this manual.  Improper 

adjustment can result in 

tool failure or other serious 

hazards.

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 distraction and injury.

2.  Route the air hose along a safe 

route to reach the work area without 

creating 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 objects 

(such as utility lines or foreign 

objects) nearby that will present a 

hazard while working.
