7.
Mandrel mounted 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 accessory may
become loose and be ejected at high velocity.
8.
Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks. If power tool or accessory is
dropped, inspect for damage or install an
undamaged
accessory.
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged accessories
will normally break apart during this test time.

must be capable of filtrating particles generated
by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
10. Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken accessory
may fly away and cause injury beyond immediate
area of operation.
11.
Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
12. 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.
13. Use clamps to support workpiece 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.
14. 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.

16. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the

17. Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.

materials. Sparks could ignite these materials.

Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
or
rotating accessory. Pinching or snagging causes rapid
stalling of the rotating accessory which in turn causes
the uncontrolled power tool to be forced in the direction
opposite of the accessory's rotation.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the
material causing the wheel to climb out or kick out. The
wheel may either jump toward or away from the operator,
depending on direction of the wheel's movement at the
point of pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can control
kickback forces, if proper precautions are taken.
b) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d) Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direction
as the chips are thrown). Feeding the tool in the
wrong direction causes the cutting edge of the bit
to climb out of the work and pull the tool in the
direction of this feed.
