• Maintain a firm grip on the power tool and posi-
tion 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 or kickback forces, if
proper precautions are taken.
• Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
• Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to the
wheel's movement at the point of snagging.
• 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.
• Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
• Use only wheel types that are recommended
for your power tool and the specific guard de-
signed for the selected wheel. Wheels for which
the power tool was not designed cannot be ade-
quately guarded and are unsafe.
• Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding, side forces ap-
plied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are
of correct size and shape for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel flanges.
• Do not use worn down wheels from larger pow-
er tools. Wheel intended for larger power tool is
not suitable for the higher speed of a smaller tool
and may burst.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
• Do not "jam" the cut-off wheel or apply exces-
sive pressure. Do not attempt to make an ex-
cessive 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 body in line with and be-
hind the rotating 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.
• When wheel is binding 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 corrective action to
eliminate the cause of wheel binding.
• Do not restart the cutting operation in the work-
piece. Let the wheel reach full speed and care-
fully reenter 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
minimize the risk of wheel pinching and kick-
back. 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 existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
• Do not use excessively oversized sanding disc
paper. Follow manufacturers recommenda-
tions, when selecting sanding paper. Larger
sanding paper extending beyond the sanding pad
presents a laceration hazard and may cause snag-
ging, tearing of the disc or kickback.
Safety Warnings Specific for Polishing Operations:
• Do not allow any loose portion of the polish-
ing 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.
Safety Warnings Specific for Wire Brushing
Operations:
• Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
• If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work load
and centrifugal forces.
Additional Safety Warnings
• The arbour size of wheels, sanding drum or any
other accessory must properly fit the spindle
or collet of the power tool. Accessories that do
not match the mounting hardware of the power
tool will run out of balance, vibrate excessively and
may cause loss of control.
• Mandrel mounted wheels, sanding drums, cut-
ters or other accessories must be fully inserted
into the collet or chuck. The "overhang" or the
length of the mandrel from the wheel to the
collet must be minimal. If the mandrel is insuf-
ficiently held and/or the overhang of the wheel is
too long, the mounted wheel may become loose
and ejected at high velocity.
• After changing the bits or making any adjust-
ments, make sure the collet nut, chuck or any
other adjustment devices are securely tight-
ened. Loose adjustment devices can unexpectedly
shift, causing loss of control, loose rotating compo-
nents will be violently thrown.
