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.
I) 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) Position the cord clear of the spinning
accessory. lf you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning wheel.
n) 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.
o) 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.
p) Regularly clean the power tool's air vents. The
10
motor's fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
q) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
r) 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. 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
Electric Circular Saw
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 10mm 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.
lnvestigate 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.
