Safety Rules for Oscillating Tools
Hold power tools by insulated gripping
surfaces when performing an operation
where the cutting tools may contact
hidden wiring. Contact with a "live" wire will
make exposed metal parts of the tool "live" and
shock the operator. Do not drill, fasten or break
into existing walls or other blind areas where
electrical wiring may exist. If this situation is
unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
Use a metal detector to determine if there
are gas or water pipes hidden in the work
area or call the local utility company for
assistance before beginning the operation.
Striking or cutting into a gas line will result in
explosion. Water entering an electrical device
may cause electrocution.
Always hold the tool firmly with both hands
for maximum control. Keep proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
Keep hands away from cutting area. Do
not reach under the material being cut. The
proximity of the blade to your hand is hidden
from your sight.
Do not use dull or damaged blades. Bent
blade can break easily or cause kickback.
Exercise extreme caution when handling
the accessories. The accessories are very
sharp.
Wear protective gloves when changing
cutting accessories. Accessories become
hot after prolonged usage.
Use thick cushioned gloves and limit the
exposure time by taking frequent rest
periods. Vibration caused by the tool may be
harmful to the hands and arms.
Before scraping, check workpiece for nails.
If there are nails, either remove them or set
them well below intended finished surface.
Striking a nail with accessory edge could
cause the tool to jump.
Do not wet sand with this tool. Liquids
entering the motor housing is an electrical
shock hazard.
Never work in area which is soaked with a
liquid, such as a solvent or water, or
dampened such as newly applied
wallpaper. There is an electrical shock
hazard when working in such conditions with a
power tool and heating of the liquid caused by
scraping action may cause harmful vapors to
be emitted from workpiece.
Always wear eye protection and a dust
mask for dusty applications and when
sanding overhead. Sanding particles can be
absorbed by your eyes and inhaled easily
and may cause health complications.
Use special precautions when sanding
chemically pressure treated lumber, paint
that may be lead based, or any other
materials that may contain carcinogens. A
suitable breathing respirator and protective
clothing must be worn by all persons entering
the work area. Work area should be sealed by
plastic sheeting and persons not protected
should be kept out until work area is
thoroughly cleaned.
Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyond the sanding pad causing snagging,
tearing of the paper or kick-back. Extra paper
extending beyond the sanding pad can also
cause serious lacerations.
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.
