l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable materials. Sparks could ignite
these materials.
p) 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 wheel, backing pad,
brush or any other 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 at the point of the binding.
e
)
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 guarded or controlled.
f) The arbor size of wheels, flanges, backing pads or any other accessory must
properly fit the spindle of the power tool. Accessories with arbor holes that
do not match the mounting hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.
g
)
Do not use a damaged accessory. Before each use inspect the accessory
such as abrasive wheels for chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an undamaged accessory. After
inspecting and 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.
h) Wear personal protective equipment. Depending on application, use face
shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing 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 filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
i) 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.
j) Hold power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an electric shock.
k) 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.
