shatter.
e) Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
f) Do not use worn down reinforced wheels
from larger power tools. Wheels intended for
a larger power tool are not suitable for the higher
speed of a smaller tool and may burst.
g) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded or
controlled.
h) The arbour size of wheels and flanges must
properly fit the spindle of the power tool.
Wheels and flanges with arbour holes that do not
match the mounting hardware of the power tool
will run out of balance, vibrate excessively and
may cause loss of control.
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
10
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,
Lithium-Ion Cordless Circular Saw
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
