WORK SECURELY. Other aids such as the, spring, bar, or C-clamps
may be appropriate for certain sizes and shapes of workpiece. Use
care in selecting and placing these clamps and make a dry run before
making a cut.

CAUTION: Wear appropriate hearing protection during use.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
WARNING: 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 (CCA).
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.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the
skin may promote absorption of harmful chemicals.

Power Supply

Be sure your power supply agrees with the nameplate marking. 120
volts, "60 Hz" means alternating current (normal 120 volt, 60 Hz
house current).
A voltage decrease of more than 10% will cause a loss of power and
overheating.

Cutting Capacity

The wide vise opening and high pivot point provide cutting capacity
for many large pieces. Use the cutting capacity chart to determine
total maximum size of cuts that can be made with a new wheel.
CAUTION: CERTAIN LARGE, CIRCULAR OR IRREGULARLY
SHAPED OBJECTS MAY REQUIRE ADDITIONAL HOLDING
MEANS IF THEY CANNOT BE HELD SECURELY IN VISE.
CAUTION: DO NOT CUT MAGNESIUM WITH THIS TOOL.
