SAVE ALL WARNINGS AND INSTRUCTIONS FORFUTURE REFERENCE
The term power tool in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordIess) power tool.
a) Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b) Do not operate power tools in explosive atmo-
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk
of electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
a) Stay alert, watch what you are doing and
use common sense when operating a power
tool. Do not use a power tool while you are

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 a polishing
is snagged or pinched by the workpiece, the
edge of the that is entering into the
pinch point can dig into the material causing the
to climb out or kick out. The
may either jump toward or away from the
operator depending on direction of the ’s
movement at the point of pinching. Polishing
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:
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.
Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
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.
Use special care when working corners and
sharp edges. 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, woodcarving blade
or toothed saw blade. Such blades create
frequent kickback and loss of control.
FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS
