due to damaged parts, gummy deposits, or a build-
up of debris.
c) The lower guard may be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts." Raise lower guard by
retracting handle and as soon as blade enters the
material, the lower guard must be released. For
all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is
covering the blade before placing saw down
on bench or floor. An unprotected, coasting
blade will cause the saw to walk backwards, cutting
whatever is in its path. Be aware of the time it takes
for the blade to stop after switch is released.
ADDITIONAL SAFETY
RULES FOR YOUR
CUTTING-OFF MACHINES
a) The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so 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 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.
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 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
