Accessories running faster than their RATED
SPEED can break and fly apart.

Incorrectly sized accessories cannot be
adequately controlled.
The arbor size of wheels, sanding drums or
any other accessory must properly fit the
s p i n d l e o r c o l l e t o f t h e p o w e r t o o l .
Accessories that do not match the mounting
hardware of the power tool will run out of
balance, vibrate excessively and may cause
loss of control.
Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck.
If the
mandrel is insufficiently held and/or the
overhang of the wheel is too long, the
mounted wheel may become loose and be
ejected at high velocity.
Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
sanding drum for cracks, tear or excess
wear, wire brush for loose or cracked

undamaged accessory. After inspecting

yourself and bystanders away from the
plane of the rotating accessory and run the
power tool at maximum no-load speed for

protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations.
The dust
mask or respirator must be capable of
f i l t r a t i n g p a r t i c l e s g e n e r a t e d b y y o u r
operation. Prolonged exposure to high
intensity noise may cause hearing loss.
Keep bystanders a safe distance away
from work area. Anyone entering the work
a r e a m u s t w e a r p e r s o n a l p r o t e c t i v e
equipment.
Fragments of workpiece or of a
broken accessory may fly away and cause
injury beyond immediate area of operation.
Hold power tool by insulated gripping
s u r f a c e s o n l y , w h e n p e r f o r m i n g a n
operation where the cutting accessory may
contact hidden wiring.
Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and
could give the operator an electric shock.
Always hold the tool firmly in your hand(s)
during the start-up.
The reaction torque of
the motor, as it accelerates to full speed,
can cause the tool to twist.
U s e c l a m p s t o s u p p o r t w o r k p i e c e
whenever practical. Never hold a small
workpiece in one hand and the tool in the
other hand while in use.
Clamping a small
workpiece allows you to use your hand(s) to
control the tool. Round material such as
dowel rods, pipes or tubing have a tendency
to roll while being cut, and may cause the
bit to bind or jump toward you.
Position the cord clear of the spinning
accessory.
If you lose control, the cord may
be cut or snagged and your hand or arm
may be pulled into the spinning accessory.
Never lay the power tool down until the
accessory has come to a complete stop.
The
spinning accessory may grab the surface and
pull the power tool out of your control.
After changing the bits or making any
adjustments, make sure the collet nut,
chuck or any other adjustment devices are
s e c u r e l y t i g h t e n e d .
L o o s e a d j u s t m e n t
devices can unexpectedly shift, causing loss
of control, loose rotating components will
be violently thrown.
Do not run the power tool while carrying it
at your side.
Accidental contact with the
s p i n n i n g a c c e s s o r y c o u l d s n a g y o u r
clothing, pulling the accessory into your
body.
Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside
the housing and excessive accumulation of
p o w d e r e d m e t a l m a y c a u s e e l e c t r i c a l
hazards.
D o n o t o p e r a t e t h e p o w e r t o o l n e a r
flammable materials.
Sparks could ignite
these materials.
Do not use accessories that require liquid
c o o l a n t s .
U s i n g w a t e r o r o t h e r l i q u i d
coolants may result in electrocution or
shock.
Use only in well-ventilated area.
Working in
a safe environment reduces risk of injury.
Allow for sufficient space, at least 6”,
between your hand and the spinning bit.
Do not reach in the area of the spinning
bit.
The proximity of the spinning bit to your
hand may not always be obvious.
