4. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fly apart.
5. The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately controlled.
6. The arbour size of accessories must properly
fit the collet of the power tool. 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.
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

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.

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.

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. 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.
15. 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.

adjustments, make sure the collet nut, chuck

rotating components will be violently thrown.
17. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
18. Regularly clean the power tool's air vents. The

or 19. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
20. Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
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.
