■
Wear personal protective equip-
ment. 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 frag-
ments.
The eye protection must be capable
of stopping flying debris generated by various
operations. The dust mask or respirator must be
capable of filtering particles generated by your
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 protec-
tive equipment.
Fragments of workpiece or
of a broken accessory may fly away and cause
injury beyond immediate area of operation.
■
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 could give the operator an electric
shock.
■
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.
■
Never lay the power tool down until
the accessory has come to a complete
stop.
The spinning accessory may grab the sur-
face and pull the power tool out of your control.
■
Do not run the power tool while car-
rying 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 pow -
dered 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, 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 power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
■
Maintain a firm grip on the power tool
and position your body and arm to
allow you to resist kickback forces. Al-
ways 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.
■
Never place your hand near the ro-
tating accessory.
Accessory may kickback
over your hand.
■
Do not position your body in the area
where power tool will move if kick-
back occurs.
Kickback will propel the tool in
direction opposite to the wheel’s movement at the
point of snagging.
■
Use special care when working cor-
ners, 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.
■
Do not attach a saw chain wood-
carving blade or toothed saw blade.
Such blades create frequent kickback and loss of
control.
