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
