AIR METAL SHEAR
Safety
WARNING!
This manual provides critical safety instructions on the proper setup, operation, maintenance, and service of this
machine/tool. Save this document, refer to it often, and use it to instruct other operators.
Failure to read, understand and follow the instructions in this manual may result in fire or serious personal
injury—including amputation, electrocution, or death.
The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in a safe environment, personnel training and
usage authorization, proper inspection and maintenance, manual availability and comprehension, application of
safety devices, cutting/sanding/grinding tool integrity, and the usage of personal protective equipment.
Edisons will not be held liable for injury or property damage from negligence, improper training, machine
modifications or misuse.
Some dust created by power sanding, sawing, and grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks, cement and other masonry products.
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures 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 those dust masks that are
specially designed to filter out microscopic particles.
Safety Instructions
Keep all safety devices in place and in working order.
Remove adjusting keys and wrenches. Form habit of checking to see that keys and adjusting wrenches are
removed from tool before operation.
Keep work area clean. Cluttered areas and benches invite accidents.
Keep children and visitors away. All children and visitors should be kept at a safe distance from work area.
Make workshop child proof. Make sure to lock your shop and shut-OFF the power and air supply.
Do not force tool. It will do the job better and safer at the rate for which it was designed.
Use the right tool. Do not force tool or attachment to do a job for which it was not designed.
DO NOT USE UNDER THE INFLUENCE OF ALCOHOL, OR WHEN TIRED.
Use correct air pressure. Exceeding the maximum PSI rating of this tool may cause seal damage,
unpredictable operation, or line burst.

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.
