properly, they must be serviced before use.
Lower guard may operate sluggishly 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 the lower guard by
retracting handle and as soon as the 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 the 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.
l) 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. If 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
