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 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.
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 fly 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 powdered metal may cause
electrical hazards.
o) Do not operate the power tool near flammable 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.
Further Safety Instructions for All Operations
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 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 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.
Safety Warnings Specific for Polishing Operations
a) Do not allow any loose portion of the polishing bonnet or its attachment
strings to spin freely. Tuck away or trim any loose attachment strings. Loose
and spinning attachment strings can entangle your fingers or snag on the
workpiece.
