n) Use clamps to support workpiece whenever practical. Never
hold a small workpiece in one hand and the tool in the other
hand while in use. Clamping a small workpiece allows you to use
your hand(s) to control the tool. Round material such as dowel rods,
pipes or tubing have a tendency to roll while being cut, and may
cause the bit to bind or jump toward you.
o) 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.
p) After changing the bits or making any adjustments, make
sure the collet nut, chuck or any other adjustment devices are
securely tightened. Loose adjustment devices can unexpectedly
shift, causing loss of control, loose rotating components will be
violently thrown.
q) 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.
r) 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.
s) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
t) 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, sanding band, 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.
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 The
operator can control torque reactions or kickback forces, if proper
precautions are taken.
b) 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.
c) Do not attach a toothed saw blade. Such blades create
frequent kickback and loss of control.
d) Always feed the bit into the material in the same direction as
the cutting edge is exiting from the material (which is the same
direction as the chips are thrown). Feeding the tool in the wrong
direction causes the cutting edge of the bit to climb out of the work
and pull the tool in the direction of this feed.
e) When using rotary files, always have the work securely
clamped. These wheels will grab if they become slightly canted
in the groove, and can kickback. When a cut-off wheel grabs, the
wheel itself usually breaks. When a rotary file, high-speed cutter or
tungsten carbide cutter grabs, it may jump from the groove and you
could lose control of the tool.

Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your power
tool and only for recommended applications. For example: do
not grind with the side of a cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
b) For threaded abrasive cones and plugs use only undamaged
wheel mandrels with an unrelieved shoulder flange that are of
correct size and length. Proper mandrels will reduce the possibility
of breakage.
c) Do not "jam" the cut-off wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut. Overstres-
sing the wheel increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility of kickback or
wheel breakage.
d) Do not position your body in line with and behind the rota-
ting wheel. When the wheel, at the point of operation, is moving
away from your body, the possible kickback may propel the
spinning wheel and the power tool directly at you.
e) When wheel is pinched, snagged or when interrupting a cut
for any reason, switch off the power tool and hold the power
tool motionless until the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate and take correc-
tive action to eliminate the cause of wheel pinching or snagging.
f) Do not restart the cutting operation in the workpiece. Let the
wheel reach full speed and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power tool is restarted in the
workpiece.
g) Support panels or any oversized workpiece to minimize the
risk of wheel pinching and kickback. Large workpieces tend to
sag under their own weight. Supports must be placed under the
workpiece near the line of cut and near the edge of the workpiece on
both sides of the wheel.
h) Use extra caution when making a "pocket cut" into existing
walls or other blind areas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects that can cause kickback.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use personal protective equipment. Always wear eye protection.
Protective equipment such as a dust mask, non-skid safety shoes,
