• 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.
• 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.
• 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.
• Use only a single wheel.
Multiple wheels can wear
unevenly, resulting in kickback and could break and
fly apart causing personal injury.

WARNING
To reduce the risk of injury in ap-
plications that produce a consid-
erable amount of dust, use an OSHA compliant
dust extraction solution in accordance with the
solution’s operating instructions.
• Always use common sense and be cautious when
using tools.
It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
•
Maintain labels and nameplates.
These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free

WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
Kickback causes and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging causes
rapid stalling of the rotating wheel which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the wheel'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 entered 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 the direction of
the wheel's movement at the point of pinching. Abra
-
sive wheels may also break under these conditions.
Kickback is the result of saw misuse and/or incor
-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
• 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 line with the rotat
-
ing wheel.
Kickback 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,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade.
Such
blades create frequent kickback and loss of control.
• Do not "jam" the 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.
• 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
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.
