GUARD FUNCTION
■ Check the guard for proper closing before each
use. Do not operate the saw if guard does not move
freely and enclose the blade instantly. Never clamp
or tie the guard so that the blade is exposed.
If saw
is accidentally dropped, guard may be bent. Check to
make sure that guard moves freely and does not touch
the blade or any other part, in all angles and depths
of cut.
■ Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use.
Guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
■ Assure that the base plate of the saw will not shift
while performing the “plunge cut”.
Blade shifting
sideways will cause binding and likely kick back.
■ Always observe that the 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.
SAFETY INSTRUCTIONS FOR ABRASIVE
CUTTING-OFF OPERATIONS
CUT-OFF MACHINE SAFETY WARNINGS
■ 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.
■ Use only 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.
■ 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.
■ 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.
■ 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.
■ 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.
■ 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.
■ 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.
■ 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 the operation. Prolonged exposure to
high intensity noise may cause hearing loss.
■ 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.
■ 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.
■ 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.
■ 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.
■ 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.
■ Do not operate the power tool near flammable
materials.
Sparks could ignite these materials.
■ 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.
