i) Do not use damaged wheels. Before
each use, inspect the wheels for chips
and cracks. If power tool or wheel is
dropped, inspect for damage or install an
undamaged wheel. After 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.
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.
g) When wheel is binding or when
interrupting a cut for any reason, switch
off the power tool and hold the power tool
motionless until the wheel comes to a
complete stop. Never attempt to remove
the wheel from the cut while the wheel
is in motion otherwise kickback may
occur.
Investigate and take corrective action to
eliminate the cause of wheel binding.
h) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power tool
is restarted in the workpiece.
i) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback.
Large workpieces tend to sag under
their own weight. Supports must be placed
under the workpiece near the line of cut and
near the edge of the workpiece on both sides of
the wheel.
j) Use extra caution when making a “pocket
cut” into existing walls or other blind
areas.
The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can
cause kickback.
