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 paints,
• crystalline silica from bricks and cement
and other masonry products, and
• MAXIMUM RPM OF 22,000
• MAX AIR PRESSURE: 90
PSIG, 6.2 BAR
• RPM OF THE ACCESSORY
MUST EXCEED TOOL RPM

SAFETY GOGGLES
• 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.

FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY.
THIS INSTRUCTION MANUAL CONTAINS
IMPORTANT SAFETY INFORMATION.
READ THIS INSTRUCTION MANUAL CAREFULLY
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 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.
• 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.
