inspecting and installing the wheel, position yourself and bystanders away from the plane
of the rotating wheel and run the power tool at maximum no load speed for one minute.
Damaged wheels will normally break apart during this test time.
j) Wear personal protective equipment. Depending on application, use face shield, safety
goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and
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.
k) 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 wheel may fly away
and cause injury beyond immediate area of operation.
l) Hold the 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.
m) Never lay the power tool down until the accessory has come to a complete stop.
The spinning
wheel may grab the surface and pull the power tool out of your control.
n) 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.
o) 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.
p) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
KICKBACK AND RELATED WARNINGS
- Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes
rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in
the direction opposite of the wheel’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 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. Always use auxiliary handle, if provided, for maximum control
over kickback or torque reaction during start-up. The operator can control torque reactions 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 line with the rotating wheel. Kickback will propel the tool in
direction opposite to the wheel’s movement at the point of snagging.
d) 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.
e) Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of
control.
f) Do not “jam” the wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of kickback or wheel breakage.
