PERSONAL SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
WORK AREA SAFETY
ELECTRICAL SAFETY
Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodi ed plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase
the risk of electric shock.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use
of a cord suitable for outdoor use reduces the risk
of electric shock.
If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, re and/or
serious injury. Save all warnings and instructions for future reference
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits
etc., in accordance with these instructions,
taking into account the working conditions and
the work to be performed. Use of the power tool
for operations different from those intended could
result in a hazardous situation.
Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the in uence of drugs, alcohol or
medication. A moment of inattention while oper-
ating power tools may result in serious personal
injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions
will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools with
your nger on the switch or energising power tools
that have the switch on invites accidents.
SPECIFIC SAFETY RULES
BATTERY TOOL USE AND CARE
Recharge only with the charger speci ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of re
when used with another battery pack.
SERVICE
Have your power tool serviced by a quali ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
Safety Warnings Common for Grinding, Sand-
ing, Wire Brushing or Abrasive Cutting-Off
Operations:
This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool. Read
all safety warnings, instructions, illustrations
and speci cations provided with this power tool.
Failure to follow all instructions listed below may
result in electric shock, re and/or serious 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 speci -
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 y apart.
The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
The arbour size of wheels, anges, backing
pads or any other accessory must properly t
the spindle of the power tool. Accessories with
arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, 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, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory 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 acces-
sories will normally break apart during this test
time.
Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and work shop apron capable of stopping
small abrasive or workpiece fragments. The
eye protection must be capable of stopping
ying debris generated by various operations.
The dust mask or respirator must be capable of
ltrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing 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 y away and cause injury beyond immediate
area of operation.
HHold power tool by insulated gripping surfac-
es only, when performing an operation where
the cutting accessory may contact hidden wir-
ing or its own cord. Cutting accessory contacting
a live wire may make exposed metal parts of the
power tool live and shock the operator.
Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
Never lay the power tool down until the acces-
sory 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 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 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.
Use power tools only with speci cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
When battery pack is not in use, keep it away
from other metal objects like paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery termi-
nals together may cause burns or a re.
Under abusive conditions, liquid may be eject-
ed from the battery, avoid contact. If contact
accidentally occurs, ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.

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 rm 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 kick back 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 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
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
Safety Warnings Specific for Grinding and
Abrasive 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 can not
be adequately guarded and are unsafe.
The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed to-
wards the operator. The guard helps to protect
operator from broken wheel fragments and ac-
cidental contact with wheel.
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 reducing 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 Abra-
sive Cutting-Off Operations:
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 bind-
ing 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 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 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 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 "pocketcut"
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 Speci c for Sanding Opera-
tions:
Do not use excessively oversized sanding disc
paper. Follow manufacturers recommenda-
tions, 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 Speci c for Wire Brushing
Operations:
Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
over stress 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 workload
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 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 spe-
cially designed to lter out microscopic particles.
