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 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.
C) Do not position your body in line with the
rotating wheel. 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
