d) The rated speed of the accessory must be at least equal to the maximum
speed communicated on the power tool. Accessories that rotate faster than the
permissible level can break and fly apart.
e) The outside diameter and thickness of your backing plate must be within capacity
rating of your power tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
f ) Threaded mounting of accessories must match the power tool’s spindle thread.
For accessories mounted by flanges, the arbor hole of the accessory must fit
the locating diameter of the flange. 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.
g) Do not use a damaged accessory. Before each use inspect the accessory such as
backing plate for cracks or tears. 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 a workshop apron capable of stopping small abrasives
or flying 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 material or pieces of
a broken accessory may fly away and cause injury beyond the area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an operation
where the accessory may contact hidden wiring or its own cord. A spinning
accessory contacting a “live” wire may make exposed metal parts of the power
tool “live” and shock the operator.
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 in causing injury.
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 may snag 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 or overheating.
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
plate, brush, or any other accessory. Pinching or snagging causes rapid stalling of
