Safety Rules for Rotary Tools
GFCI and personal protection devices like
electrician’s rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply.
While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a
hazard to the operator.
Keep handles dry, clean and free from oil
and grease.
Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
t h e t o o l s i n c e i n t e r n a l w i r e s m a y b e
m i s p l a c e d o r p i n c h e d o r s a f e t y g u a r d
r e t u r n s p r i n g s m a y b e i m p r o p e r l y
mounted.
Certain cleaning agents such as
gasoline, carbon tetrachloride, ammonia,
etc. may damage plastic parts.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
c a u s e c a n c e r , b i r t h d e f e c t s o r o t h e r
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.

edge of the workpiece on both sides of the
wheel.
Use extra caution when making a pocket
cut
into existing walls or other blind
areas.
The protruding wheel may cut gas or
water pipes, electrical wiring or objects that
can cause kickback.
▶ Safety warnings specific for
wire brushing operations:
Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
excessive load to the brush.
The wire
bristles can easily penetrate light clothing
and/or skin.
Allow brushes to run at operating speed
for at least one minute before using them.
During this time no one is to stand in front
or in line with the brush.
Loose bristles or
wires will be discharged during the run-in
time.
Direct the discharge of the spinning wire
brush away from you.
Small particles and
tiny wire fragments may be discharged at
h i g h v e l o c i t y d u r i n g t h e u s e o f t h e s e
brushes and may become imbedded in your
skin.
