the least amount of wheel is exposed
towards the operator. Position yourself
and bystanders away from the plane
of the rotating wheel. The guard helps to
protect operator from broken wheel fragments
and accidental contact with wheel.
b) Use only bonded reinforced or diamond
cut-off wheels for your power tool. Just
because an accessory can be attached to your
power tool, it does not assure safe operation.
c) The rated speed of the accessory must
be at least equal to the maximum speed
marked on the power tool. Accessories
running faster than their rated speed can break
and fly apart.
d) Wheels must be used only for
recommended applications. For example:
do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended
for peripheral grinding, side forces applied to
these wheels may cause them to 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
12
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
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.
20V Cordless Brushless Circular saw
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.
