AND UNDERSTAND ALL INFORMATION BEFORE
OPERATING THIS TOOL.
• Always operate, inspect and maintain this tool in
accordance with American National Standards
Institute Safety Code of Portable Air Tools (ANSI
B186.1) and any other applicable safety codes
and regulations.
• For safety, top performance and maximum durability
of parts, operate this tool at 90 psig 6.2 bar max
air pressure with 3/8" diameter air supply hose.
• Always wear impact-resistant eye and face
protection when operating or performing
maintenance on this tool.
• Always wear hearing protection when using this
tool. High sound levels can cause permanent hearing
loss. Use hearing protection as recommended by
your employer or OSHA regulation.
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must be
physically able to handle the bulk, weight and
power of this tool.
• Air powered tools can vibrate in use. Vibration,
repetitive motions or uncomfortable positions over
extended periods of time may be harmful to your
hands and arms. Discontinue use of tool if discomfort,
tingling feeling or pain occurs. Seek medical advice
before resuming use.
• Air under pressure can cause severe injury. Never
direct air at yourself or others. Always turn off the
air supply, drain hose of air pressure and detach tool
from air supply before installing, removing or
adjusting any accessory on this tool, or before
performing any maintenance on this tool. Failure to
do so could result in injury. Whip hoses can cause
serious injury. Always check for damaged, frayed
or loose hoses and fittings, and replace immediately.
Do not use quick detach couplings at tool. See
instructions for correct set-up.
• Place the tool on the work before starting the tool.
• Slipping, tripping and/or falling while operating air
tools can be a major cause of serious injury or
death. Be aware of excess hose left on the walking
or work surface.
• Keep body working stance balanced and firm. Do
not overreach when operating the tool.
• Anticipate and be alert for sudden changes in motion
during start up and operation of any power tool.
• Do not carry tool by the hose. Protect the hose from
sharp objects and heat.
• Tool shaft may continue to rotate briefly after throttle
is released. Avoid direct contact with accessories
during and after use. Gloves will reduce the risk of
cuts or burns.
•Keep away from rotating end of tool. Do not
wear jewelry or loose clothing. Secure long hair.
Scalping can occur if hair is not kept away from tool and
accessories. Choking can occur if neckwear is not
kept away from tool and accessories.
• Correct grinding wheel mounting is necessary to
prevent injury from broken wheels. Do not use
chipped or cracked grinding wheels. Grinding
wheels should be a free fit on the spindle to prevent
stress at the hole. Use only wheel collars that come
with the grinder for mounting the grinding wheel.
Flat washers or other adapters may over stress the
wheel. Always use heavy paper blotter discs
between the wheel collars and the grinding wheel
Tighten the wheel on the spindle to prevent spin off
when the air grinder is turned off.
• Do not lubricate tools with flammable or volatile
liquids such as kerosene, diesel or jet fuel.
• Do not force tool beyond its rated capacity.
• Do not remove any labels. Replace damaged labels.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY
OPERATION
When using the grinder be careful not to exert excessive force. Too
much force could be hazardous if it causes the cutting tool spindle
to bend or break.
The burning of the work piece or excessive speed reduction
indicates too much force being applied. Changing to a free
cutting tool may be better for the desired rate of speed and stock
removal.
Avoid hazardous conditions by making sure there is sufficient force
on the spindle of the cutting tool by placing the spindle 7/16" or
more inside the collet.
