Tool Set Up

 

TO PREVENT

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

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.
