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
• 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.
• 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.
• 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 any
damaged labels.

Air Supply...
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measures 90 PSI at
the tool while running free. Higher pressure (over 90 psig; 6.2
bar) raises performance beyond the rated capacity of the tool,
which will shorten tool life because of faster wear and could
cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in
the air line will cause damage to the tool. Drain the air tank
daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hookup procedure can be viewed in
the above figure.
The air inlet used for connecting air supply has standard 1/4"
NPT. Line pressure should be increased to compensate for
unusually long air hoses (over 25 feet). Minimum hose diameter
should be 3/8" I.D. and fittings should have the same inside
dimensions and be tightly secured.
Operation...
When using the grinder, be careful not to exert excessive force.
Too much force may 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 condition by making sure there is sufficient
gripping force on the spindle of the cutting tool by placing the
spindle 7/16” or more inside the collet.
Lubrication...
Lubricate the air motor daily with quality air tool oil. If no air line
oiler is used, run a teaspoon of oil through the tool. The oil can
be squirted into the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool. The amount of oil
to be used is 1 ounce. Overfilling will cause a reduction in the
power of the tool.
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air
line, moisture or restrictions in air pipes or the use of hose
connections of improper size or poor condition may reduce air
supply. Grit or gum deposits in the tool may cut power and may
be corrected by cleaning the air strainer and flushing out the tool
with gum solvent oil or an equal mixture of SAE #10 oil and
kerosene. If outside conditions are in order, and the tool
continues erratic action on low power, disconnect tool from hose
and contact your nearest authorized service center.
