unpredictable behavior resulting in fire, explosion or
risk of injury.
• Do not expose a battery pack or tool to fire or ex-
cessive temperature. Exposure to fire or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging im-
properly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
SERVICE
• Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of
battery packs should only be performed by the manu-
facturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
POLISHERS
Safety Warnings Common for Polishing:
• This power tool is intended to function as a polish-
er. Read all safety warnings, instructions, illustra-
tions and specifications provided with this power
tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
• Operations such as grinding, sanding, wire brush-
ing or cutting-off are not recommended to be per-
formed with this power tool. Operations for which
the power tool was not designed may create a hazard
and cause personal injury.
• Do not use accessories which are not specifically
designed and recommended by the tool manufac-
turer. 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 fly 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
polisher spindle thread. For accessories mounted
by flanges, the arbour hole of the accessory must
fit the locating diameter of the flange. Accessories
that do not match the mounting hardware 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 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 maxi-
mum no-load speed for one minute. Damaged ac-
cessories will normally break apart during this test time.
• Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various operations.
The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged ex-
posure 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 work-
piece or of a broken accessory may fly away and cause
injury beyond immediate area of operation.
• Never lay the power tool down until the accessory
has come to a complete stop. The spinning acces-
sory 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 flammable
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 Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled 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 enter-
ing 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 opera-
tor, 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 in-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below.
• Maintain a firm 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 reac-
tions or kickback forces, if proper precautions are taken.
• Never place your hand near the rotating accessory.
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 Specific for Polishing Operations:
• Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment strings.
Loose and spinning attachment strings can entangle
your fingers or snag on the workpiece.
Additional Safety Warnings
• Maintain labels and nameplates. These carry im-
portant information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
