accessory is dropped, inspect for damage
or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane
of the rotating accessory and run the power
tool at maximum no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
h) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments.
The eye protection must
be capable of stopping fl ying debris generated by
various operations. The dust mask or respirator
must be capable of fi ltrating particles generated
by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
i)
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 accessory may fl y
away and cause injury beyond immediate area of
operation.
j)
Hold 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 shock the operator.
k) 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 accessory.
l)
Never lay the power tool down until the
accessory has come to a complete stop.
The
spinning accessory may grab the surface and pull
the power tool out of your control.
m) 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.
n) Regularly clean the power tool’s air vents.
The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powered metal may
cause electrical hazards.
o) Do not operate the power tool near fl ammable
materials.
Sparks could ignite these materials.
p) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may
result in electrocution or shock.
q) Do not use Type 11 (fl aring cup) wheels on this
tool.
Using inappropriate accessories can result in
injury.
r)
Always use side handle. Tighten the handle
securely.
The side handle should always be used
to maintain control of the tool at all times.
Causes and Operator Prevention of
Kickback
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling
of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction
opposite of the accessory’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 tool misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below:
a) Maintain
a
fi rm 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 reaction 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 the area where
power tool will move if kickback occurs.
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
or toothed saw blade.
Such blades create
frequent kickback and loss of control.
