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.

Operating Instructions • Warning Information • Parts Breakdown
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 or low power, disconnect tool from hose and contact your
nearest authorized service center.
WARRANTY
We warrant that this tool shall be free from defects in original workmanship and material and that it will be inspected by us before shipment.
