After changing the bits or making any adjustments,
Ÿ
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.
Do not run the power tool while carrying it at your
Ÿ
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
Ÿ
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
Do not operate the power tool near flammable
Ÿ
materials. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Ÿ
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
Ÿ
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
Ÿ
your body and arm to allow you to resist kickback
forces. The operator can control kickback forces, if
proper precautions are taken.
Use special care when working corners, sharp
Ÿ
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 thin toothed saw blade. Such blades
Ÿ
create frequent kickback and loss of control.
Always feed the bit into the material in the same
Ÿ
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.

When using cut-off wheels, high-speed cutters or
Ÿ
tungsten carbide cutters, 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 the steel saw, high-speed cutters or
tungsten carbide cutter grab, it may jump from the
groove and you could lose control of the tool.
Additional safety instructions for grinding
Use only wheel types that are recommended for
Ÿ
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.
For threaded abrasive cones and plugs use only
Ÿ
undamaged wheel mandrels with an unrelieved
shoulder flange that are of correct size and length.
Proper mandrels will reduce the possibility of breakage.
Do not "jam" the cut-off wheel or apply excessive
Ÿ
pressure. Do not attempt to make an excessive
depth of cut. Overstressing 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.
Do not position your hand in line with and behind the
Ÿ
rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the spinning wheel and the power
tool directly at you.
When wheel is binding or when interrupting a cut for
Ÿ
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
corrective action to eliminate the cause of wheel binding.
Do not restart the cutting operation in the
Ÿ
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.
Support panels or any oversized workpiece to
Ÿ
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.
Use extra caution when making a "pocket cut" into
Ÿ
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
Safety warnings specific for polishing operations
Do not allow any loose portion of the polishing
Ÿ
bonnet or its attachment strings to spin freely.
