Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged 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.
a) Maintain a fi rm grip on the power tool and position 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.
b) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c) Do not position your body in the area where power tool
will move if kickback occurs. Kickback 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 frequent kickback and
loss of control.
Safety Warnings Specifi c for Grinding and Abrasive
Cutting-Off Operations:
a) Use only wheel types that are recommended for your
power tool and the specifi c guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b) The guard must be securely attached to the power tool
and positioned for maximum safety, so the least amount of
wheel is exposed towards the operator. The guard helps to
protect operator from broken wheel fragments and accidental
contact with wheel and sparks that could ignite clothing.
c) 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 applied to these wheels may
cause them to shatter.
d) Always use undamaged wheel fl anges that are of correct
size and shape for your selected wheel. Proper wheel
fl anges support the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be different from
grinding wheel fl anges.
e) 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.
Additional Safety Warnings Specifi c for Abrasive
Cutting-Off Operations:
a) Do not “jam” the cut-off wheel or apply excessive
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 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.
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 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.
f) 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.
Safety Warnings Specifi c for Wire Brushing Operations:
a) 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.
b) 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.
Dust and splinters must not be removed while the machine is
running.
Never reach into the danger area of the tool when it is running.
Always use the auxiliary handle.
Always use the protecting cap when roughing-down and
separating.
Immediately switch off the machine in case of considerable
vibrations or if other malfunctions occur. Check the machine in
order to fi nd out the cause.
Always use and store the grinding disks according to the
manufacturer's instructions.
When grinding metal, fl ying sparks are produced. Take care
that no persons are endangered. Because of the danger of fi re,
no combustible materials should be located in the vicinity
(spark fl ight zone). Do not use dust extraction.
Due care should be taken that no sparks or sanding dust fl ying
from the workpiece come into contact with you.
The adjusting nut must be tightened before starting to work with
the machine.
The workpiece must be fi xed if it is not heavy enough to be
steady. Never lead the workpiece to the grinding disk with your
hand.
For accessories intended to be fi tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to accept
the spindle length.
For cutting or separating use a closed protection cap, available
as an accessory.
Do not dispose of used battery packs in the household refuse
or by burning them. Milwaukee Distributors offer to retrieve old
batteries to protect our environment.
Do not store the battery pack together with metal objects (short
circuit risk).
Use only System C 18 chargers for charging System C 18
battery packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store only in
dry rooms. Keep dry at all times.
