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 in-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below.
а) 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 kick-
back or torque reaction during start-up. The
operator can control torque reactions or kickback
forces, if proper precautions are taken.
b) Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
c) 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.
d) 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.
e) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
▪ Fix the machined piece in vice or in another ap-
propriate way.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
a) 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.
b) 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 break-
age. Flanges for cut-off wheels may be different
from grinding wheel flanges.
c) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller tool
and may burst.
▪ Always pay attention to the wheel rotation di-
rection. The torque reaction is in the opposite di-
rection of the rotation direction at the point of bind-
ing and this is a prerequisite to loosing control of
the power tool.
▪ Always guide the machine in such a way that
sparks and dust can scatter away from your
body. Power tools generate sparks which may
burn your clothes or unprotected parts of your
body.
▪ Grinding and cutting-off operations on freshly
painted metal structures is not allowed before
the paint has become dry. There is a risk of damp
paint ignition.
▪ Grinding and cutting-off operations on equip-
ment operating under pressure is not allowed.

There is a risk of explosion.
▪ Grinding and cutting-off operations of reser-
voirs, pipelines, equipment, etc., containing at
present or having contained flammable or eas-
ily ignitable substances or materials is not al-
lowed without first taking special precautions
to prevent fire and explosion. There is a risk of
fire and explosion.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
а) Do not "jam" the cut-off wheel or apply ex-
cessive 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Safety Warnings Specific for Sanding Operations:
а) Do not use excessively oversized sanding disc
paper. Follow manufacturer's 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:
а) 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 work-
piece.
Safety Warnings Specific for Wire Brushing Opera-
tions:
а) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
