ELECTRICAL SAFETY

WORK AREA SAFETY

• 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. W

ater 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 ground fault circuit inter
rupter (GFCI) protected supply. Use of an GFCI

reduces the risk of electric shock.

PERSONAL SAFETY

• 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 operating 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.

• 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, jewellery

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.

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.

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, tak

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.

• 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 terminals together

may cause burns or a re.

• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac
cidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation
or burns.

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.

• Threaded mounting of accessories must match

the grinder spindle thread. For accessories

mounted by anges, the arbour hole of the ac
cessory must t the locating diameter of the
ange. Accessories

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, backing pad for
cracks, tear or excess wear, wire brush for

loose or cracked wires. If power tool or acces

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. Frag
ments of workpiece or of a broken accessory may

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 acces
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the pow
er 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 ac
cessory 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 cool
ants. Using water or other liquid coolants may re­sult in electrocution or shock.

Kickback and Related W

Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory
rapid
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. Abra
sive 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 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 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’

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

sive Cutting-Off Operations:

•

Use only wheel types that are recommended

for your power tool and the specic guard de

signed 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 adequately protected.

• 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

operator

dental 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 ap
plied 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 pow

er 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 exces-

sive pressure. Do not attempt to make an ex­cessive depth of cut. Overstressing the wheel

increases
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 be
hind the rotating wheel. When
point of operation, is moving away from your body
the possible
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 work

piece. Let the wheel reach full speed and care-

fully reenter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the
workpiece.

•

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 recommenda
tions, when selecting sanding paper. Larger

sanding paper extending beyond the sanding pad
presents a laceration
ging, tearing of the disc or kickback.

Safety Warnings

erations:

• 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
replacement.

• WARNING: Some dust created by power sanding,
