ses the rotating insertion tool to stop suddenly.
This accelerates an uncontrolled power tool
against the rotational direction of the accessory
at the site where the accessory is jammed.
If, for example, an abrasive wheel becomes
caught or jammed in the workpiece, the edge of
the abrasive wheel which is plunged into the
workpiece may become stuck, causing the
abrasive wheel to break or resulting in kick
back. The abrasive wheel then moves towards
or away from the operator, depending on the
wheel's rotational direction. This can also
cause abrasive wheels to break.
A kickback occurs as a result of using the pow
er tool incorrectly or misguidedly. It can be pre
vented by taking appropriate precautions, as
described below.
– Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxili
ary handle, if provided, for maximum con
trol over kickback or torque reaction dur
ing start-up. The operator can control tor
que reactions or kickback forces, if proper
precautions are taken.
– Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
– Do not position your body in the area
where power tool will move if kickback oc
curs. Kickback will propel the tool in direc
tion opposite to the wheel’s movement at
the point of snagging.
– Use special care when working corners,
sharp edges etc. Avoid bouncing and snag
ging the accessory. Aorners, sharp edges
or bouncing have a tendency to snag the ro
tating accessory and cause loss of control
or kickback.
– Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of con
trol.
Specific safety warnings on sanding and abra
sive cutting
– Use only wheel types that are recommen
ded for your power tool and the specific
guard designed for the selected wheel.
Wheels for which the power tool was not
designed cannot be adequately guarded
and are unsafe.
– The grinding surface of centre depressed
wheels must be mounted below the plane
of the guard lip. An improperly mounted
wheel that projects through the plane of
the guard lip cannot be adequately protec
ted.
– The guard must be securely attached to
the power tool and positioned for maxi
mum safety, so the least amount of wheel
is exposed towards the operator. The
guard helps to protect the operator from
broken wheel fragments, accidental con
tact with wheel and sparks that could ignite
clothing.
– Wheels must be used only for recommen
ded applications. For example: do not
grind with the side of cut-off wheel. Abra
sive cut-off wheels are intended for periph
eral grinding, side forces applied to these
wheels may cause them to shatter.
– Always use undamaged wheel flanges that
are of correct size and shape for your se
lected wheel. Proper wheel flanges sup
port 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
power tools. Wheel intended for larger
power tool is not suitable for the higher
speed of a smaller tool and may burst.
Other specific safety warnings on abrasive
cutting
– Do not “jam” the cut-off wheel or apply
excessive pressure. Do not attempt to
make an excessive depth of cut. Over
stressing 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
behind 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 interrupt
ing a cut for any reason, switch off the
power tool and hold the power tool mo
tionless until the wheel comes to a com
plete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel
is in motion otherwise kickback may oc
cur. Investigate and take corrective action
to eliminate the cause of wheel binding.
– Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel
