Safety Rules for Cordless Rotary Tools
Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring. Contact with a "live" wire will
make exposed metal parts of the tool "live" and shock
the operator.
Use clamps or other practical way to secure and sup-
port the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may
lead to loss of control.
Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels
and other accessories running over rated speed can
fly apart and cause injury.
If cutting into existing walls or other blind areas
where electrical wiring may exist is unavoidable,
disconnect all fuses or circuit breakers feeding this
worksite.
Before changing accessories remove battery pack.
Accidental starting may occur because battery tools
with a battery inserted are in the operative condition.
Be aware of the switch location, when placing the
tool down or when picking the tool up. You may acci-
dentally activate the switch.
Always hold the tool with two hands during astart-
up.
The reaction torque of the motor can cause the tool to
twist.
Always wear safety goggles and dust mask. Use
only in well ventilated area. Using personal safety
devices and working in safe environment reduces risk
of injury.
After changing the bits or making any adjustments,
make sure the collet nut and any other adjustment
devices are securely tightened. Loose adjustment
device can unexpectedly shift, causing loss of control,
loose rotating components will be violently thrown.
Do not reach in the area of the spinning bit. The
proximity of the spinning bit to your hand may not
always be obvious.
Allow brushes to run at operating speed for at least
one minute before using wheel. 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.
Wire and bristle brushes must never be operated at
speeds greater than 15,000/min. Direct the dis-
charge of the spinning wire brush away from you.
Small particles and tiny wire fragments may be dis-
charged at high velocity during the “cleaning” action
with these brushes and may become imbedded in
your skin. Bristles or wires will be discharged from
the brush at high speeds.
"Wear protective gloves and face shield with wire or
bristle brushes. Apply wire or bristle brushes light-
ly to the work as only the tips of the wire/bristles do
the work.
“Heavy” pressure on bristles will cause the
wire or bristle to become overstressed, resulting in a
wiping action and will cause the bristles/wire to be
discharged."
Carefully handle both the tool and individual grind-
ing wheels to avoid chipping or cracking. Install a
new wheel if tool is dropped while grinding. Do not
use a wheel that may be damaged. Fragments from
a wheel that bursts during operation will fly away at
great velocity possibly striking you or bystanders.
Never use dull or damaged bits. Sharp bits must be
handled with care. Damaged bits can snap during
use. Dull bits require more force to push the tool,
possibly causing the bit to break.
Use clamps to support workpiece whenever practi-
cal. Never hold a small workpiece in one hand and
the tool in the other hand while in use. Allow for
sufficient space, at least 6", between your hand and
the spinning bit. Round material such as dowel rods,
pipes or tubing have a tendency to roll while being
cut, and may cause the bit to “bite” or jump toward
you. Clamping a small workpiece allows you to use
both hands to control the tool.
