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

position yourself and bystanders away from

power tool at maximum no-load speed for one
minute. Damaged accessories will normally break
apart during this test time.

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 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.
15. After changing the bits or making any
adjustments, make sure the collet nut, chuck
or any other adjustment devices are securely

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
After accessory into your body.
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.
18. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
19. Do not use accessories that require liquid
coolants. Using water or other liquid coolants may

Kickback and Related Warnings
apron 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.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool and only for recommended
applications.
