AIR METAL SHEAR 

 

 

 

 

Use proper air hose. Make sure your air hose is in good condition and is long enough to reach your work 
without stretching. 

 

Secure work. Use clamps or a vise to hold work when practical. It is safer than using your hand and frees 
both hands to operate tool. 

 

Maintain tools with care. Keep tools lubricated and clean for best and safest performance. Follow 
instructions for lubricating and changing accessories. 

 

Prevent accidental operation. Do not carry tool with hand on trigger and always disconnect from air when not 
in use. 

 

Maintain tools with care. Keep tools lubricated and clean for best and safest performance. Follow 
instructions for lubricating and changing accessories. 

 

Be aware of hose location. Hoses can easily become a tripping hazard when laid across the floor in a 
disorganized fashion. 

 

Wear approved hearing protection. Air escaping from pneumatic tools can exceed safe exposure limits and 
may cause hearing damage with prolonged exposure. 

 

Air line connection inspection. An air line that becomes disconnected from a tool can whip violently, causing 
severe injury. Verify that air line is properly connected and the fittings are tight and free of leaks. A leaking 
fitting can indicate the fitting is cracked and is about to fail. 

 

Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may 
get caught in moving parts. Nonslip footwear is recommended. Wear a protective hair covering to contain 
long hair. 

 

Always use safety glasses. Also use a face or dust mask if cutting operation is dusty. Everyday eyeglasses 
only have impact resistant lenses, they are NOT safety glasses. 

Changing bits 

When servicing or removing metal from the jaws, disconnect the shear from air to prevent an accidental start-up 
injury. 

Tool Stability 

To establish the best control possible when cutting, hold the handle and housing with two hands, and stabilize 
your hands and body against a fixed object. When free-hand cutting (using one hand) use a guide to slide the 
pneumatic shear along when making the cut to avoid severe injury. 

CAUTION! 

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as 
it applies to your individual working conditions. Use this and other tools with caution and respect. 

Failure to do so could result in serious personal injury, damage to equipment or poor work results.
