and workshop apron capable of stopping 
small abrasive or workpiece fragments. The 
eye protection must be capable of stopping fl ying 
debris generated by various operations. The dust 
mask or respirator must be capable of fi ltrating 
particles generated by your operation. Prolonged 
exposure to high intensity noise may cause hear-
ing loss.

• Keep bystanders a safe distance away from 

work area. Anyone entering the work area 
must wear personal protective equipment. 
Fragments of workpiece or of a broken accessory 
may fl y away and cause injury beyond immediate 
area of operation.

• Hold the power tool by insulated gripping 

surfaces only, when performing an operation 
where the cutting accessory may contact hid-
den wiring. Contact with a “live” wire will also 
make exposed metal parts of the power tool “live” 
and could give the operator an electric shock.

• Never lay the power tool down until the ac-

cessory has come to a complete stop. The 
spinning accessory may grab the surface and 
pull the power tool out of your control.

• Do not run the power tool while carrying it at 

your side. Accidental contact with the spinning 
accessory could snag your clothing, pulling the 
accessory into your body.

• Regularly clean the power tool’s air vents. The 

motor’s fan will draw the dust inside the housing 
and excessive accumulation of powdered metal 
may cause electrical hazards.

• Do not operate the power tool near fl ammable 

materials. Sparks could ignite these materials.

• Do not use accessories that require liquid 

coolants.  Using water or other liquid coolants 
may result in electrocution or shock.

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 acces-
sory’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.
• 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 kick-
back forces, if proper precautions are taken.

• Never place your hand near the rotating acces-

• This power tool is intended to function as a 

grinder, sander, wire brushing or cut-off tool. 
Read all safety warnings, instructions, illus-
tr ations and specifi cations provided with this 
power tool. Failure to follow all instructions listed 
below may result in electric shock, fi re and/or se-
rious injury.

• Operations such as polishing are not recom-

mended to be performed with this power tool. 
Operations for which the power tool was not de-
signed may create a hazard and cause personal 
injury.

• Do not use accessories which are not specifi -

cally designed and recommended by the tool 
manufacturer. Just because the accessory can 
be attached to your power tool, it does not assure 
safe operation.

• The rated speed of the accessory must be at 

least equal to the maximum speed marked on 
the power tool. Accessories running faster than 
their RATED SPEED can break and fl y apart.

• The outside diameter and the thickness of your 

accessory must be within the capacity rating 
of your power tool. Incorrectly sized accesso-
ries cannot be adequately guarded or controlled.

• The arbour size of wheels, fl anges,  backing 

pads or any other accessory must properly 
fi t the spindle of the power tool. Accessories 
with arbour holes that do not match the mount-
ing hardware of the power tool will run out of bal-
ance, vibrate excessively and may cause loss of 
control.

• Do not use a damaged accessory. Before 

each use inspect the accessory such as 
abrasive wheels for chips and cracks, back-
ing pad for cracks, tear or excess wear, wire 
brush for loose or cracked wires. If power 
tool or accessory is dropped, inspect for 
damage or install an undamaged accessory. 
After inspecting and installing an accessory, 
position yourself and bystanders away from 
the plane of the rotating accessory and run 
the power tool at maximum no-load speed for 
one minute. Damaged accessories will normally 
break apart during this test time.

• Wear personal protective equipment. De-

sory.  Accessory may kickback over your hand.

• 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.

• Use special care when working corners, 

sharp edges etc. Avoid bouncing and snag-
ging 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 

or toothed saw blade. Such blades create fre-
quent kickback and loss of control.

Safety Warnings Specifi c for Grinding and 
Abrasive Cutting-Off Operations:
• 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.

• The guard must be securely attached to the 

power tool and positioned for maximum safe-
ty, so the least amount of wheel is exposed 
towards the operator. The guard helps to pro-
tect operator from broken wheel fragments and 
accidental contact with wheel.

• Wheels must be used only for recommend-

ed 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 fl anges  that 

are of correct size and shape for your se-
lected wheel. Proper wheel fl anges  support 
the wheel thus reducing the possibility of wheel 
breakage. Flanges for cut-off wheels may be dif-
ferent from grinding wheel fl 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 Specifi c for Abra-
sive Cutting-Off Operations:
• Do not “jam” the cut-off wheel or apply exces-

sive pressure. Do not attempt to make an ex-
cessive depth of cut. Overstressing the wheel 
increases the loading and susceptibility to twist-
ing or binding of the wheel in the cut and the pos-
sibility 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 spin-
ning 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 occur. Investigate and take cor-
rective 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 reenter 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 
protruding wheel may cut gas or water pipes, elec-
trical wiring or objects that can cause kickback.

Safety Warnings Specifi c for Sanding Opera-
tions:
• Do not use excessively oversized sanding 

disc paper. Follow manufacturers recommen-
dations, 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 Specifi c 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 construc-
tion 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, depend-

ing on how often you do this type of work. To re-
duce 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 fi lter out microscopic 
particles.

coins, keys, nails, screws, or other small metal 
objects that can make a connection from one 
terminal to another. Shorting the battery terminals 
together may cause burns or a fi re.

ed from the battery; avoid contact. If contact 
accidentally occurs, fl ush with water. If liquid 
contacts eyes, additionally seek medical help. 
Liquid ejected from the battery may cause irritation 
or burns.

repair person using only identical replacement 
parts. This will ensure that the safety of the power
