occur. 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 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 pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
Safety Warnings Specic for Sanding Operations:
• Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding
paper extending beyond the sanding pad presents a
laceration hazard and may cause snagging, tearing
of the disc or kickback.
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
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.

WARNING
Some dust created by power sand-
ing, sawing, grinding, drilling, and
other construction activities contains chemicals
known to cause cancer, birth defects or other repro-
ductive 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 spe-
cially designed to lter out microscopic particles.

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. 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 ac-
cessory. 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 frequent
kickback and loss of control.
Safety Warnings Specic for Grinding and Abra-
sive Cutting-Off Operations:
• Use only wheel types that are recommended for
your power tool and the specic 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 ad-
equately protected.
• 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 the opera-
tor from broken wheel fragments, accidental contact
with wheel and sparks that could ignite clothing.
• 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.
• Always use undamaged wheel anges that are of
correct size and shape for your selected wheel.
Proper wheel anges support the wheel thus reduc-
ing the possibility of wheel breakage. Flanges for
cut-off wheels may be different from grinding wheel
anges.
• 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 Specic for Abrasive
Cutting-Off Operations:
• 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.
• 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 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
ASSEMBLY
