Safety warnings 

General air tool warnings 

1.  Read and understand this entire manual 

before attempting assembly or operation. 

2. 

Read and understand all warnings posted on 
the tool and in this manual. Failure to comply 
with all of these warnings may cause serious 
injury. 

3.  Replace warning labels if they become 

obscured or removed. 

4. 

Do not use this tool for other than its intended 
use. If used for other purposes, JET disclaims 
any real or implied warranty and holds itself 
harmless from any injury that may result from 
that use. 

5. 

Always wear approved safety glasses or face 
shield while using this tool. (Everyday 
eyeglasses only have impact resistant lenses; 
they are 

not 

safety glasses.) 

6.  Wear ear protectors (plugs or muffs) if the 

noise exceeds safe levels. 

7.  Wear gloves and protective clothing if 

operation produces sparks or flying particles. 
Gloves should be tight-fitting, without frayed 
fingers or hanging threads. Keep hands and 
body away from the working area of tool. 

8. 

Some dust created by power sanding, sawing, 
grinding, drilling and other construction 
activities contains chemicals known to cause 
cancer, birth defects or other reproductive 
harm. Some examples of these chemicals 
are: 

• Lead from lead based paint. 

• Crystalline silica from bricks, cement and 
other masonry products. 

• Arsenic and chromium from chemically 
treated lumber. 

Your risk of exposure varies, depending on 
how often you do this type of work. To reduce 
your exposure to these chemicals, work in a 
well-ventilated area and work with approved 
safety equipment, such as face or dust masks 
that are specifically designed to filter out 
microscopic particles. 

9. 

Do not operate an air tool continually at full 
throttle without a work load on the tool. 

10.  The air tool must be properly lubricated before 

operating.  

11.  Never start a percussion type air tool (chipper, 

breaker, buster, etc.) without securing the 
tooling in the retainer and placing the tip 
against the work surface. 

12.  Do not operate air tool without its guards in 

place. Do not modify the tool. 

13.  Do not operate this tool while tired or under 

the influence of drugs, alcohol, or any 
medication. 

14. Adopt a comfortable posture with proper 

balance, and maintain secure footing at all 
times. Non-slip footwear or anti-skid floor 
strips are recommended. 

15.  Do not wear loose clothing or jewelry. Confine 

long hair. 

16.  Excessive air pressure and too much free 

rotation may decrease life of the tool and may 
cause a hazardous situation. 

17.  Check air hoses for wear, and keep them 

away from heat and sharp edges. Repair or 
replace damaged air hose immediately. Do 
not carry tool by the air hose. 

18.  Air hose may cause tripping hazards; keep 

hose away from traffic areas. 

19.  Do not use this tool near flammable objects, 

or in potentially explosive environments. Do 
not use near live electrical wires.
