Use only accessories that are
recommended by the manufacturer for your
model.
Accessories that may be suitable for
one tool may create a risk of injury when used
on another tool.
Service
Tool service must be performed only by
qualified repair personnel.
Service or
maintenance performed by unqualified
personnel may result in a risk of injury.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use
of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of
shock or injury.
Safety Rules for Cordless Rotary Tools
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.
Hold tool by insulated gripping surfaces
when performing 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. 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.
Do not operate the flexible shaft with a
sharp bend.
Over bending the shaft can
generate excessive heat on the jacket or hand
piece. The recommended minimum is 6"
radius.
Disconnect battery pack from tool or place
the switch in the locked or off position
before making any assembly, adjustments
or changing accessories
. Such preventive
safety measures reduce the risk of starting the
tool accidentally.
Be aware of the switch location, when
placing the tool down or when picking the
tool up.
You may accidentally activate the
switch.
Always hold the hand piece firmly in your
hands during the start-up.
The reaction
torque of the motor, as it accelerates to full
speed, can cause the shaft 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 discharge of the
spinning wire brush away from you.
Small
particles and tiny wire fragments may be
discharged 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 lightly 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 grinding 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.
