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 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 work shop 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 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 into the spinning accessory.
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) D o not use accessories that require liquid coolants. Using water or other liquid coolants may
result in electrocution or shock.
q) D o not use type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can
result in injury.
r) a lways grip tool using two hands to maintain control of the tool at all times.
s) When starting the tool with a new or replacement wheel, hold the tool in a well protected
area and let it run for one minute. If the wheel has an undetected crack or flaw, it should burst
in less than one minute. Never start the tool with a person in line with the wheel. This includes
the operator.
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.
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 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. always use auxiliary handle, if provided, for maximum control
over kickback or torque reaction during start up. The operator can control torque reaction or
kickback forces, if proper precautions are taken.
b) never place your hand near the rotating accessory. Accessory may kickback over your hand.
c) Do not position your body in the area where power tool will move if kickback occurs. Kickback
will propel the tool in direction opposite to the wheel's movement at the point of snagging.
