another. Shorting the battery terminals together may
cause burns or a fire.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac-
cidentally occurs, flush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is dam-
aged or modified. Damaged or modified batteries
may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
• Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or tem-
perature 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 improperly 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
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
GRINDERS
Safety Warnings Common for Grinding, Wire
Brushing or Cutting-Off Operations:
• This power tool is intended to function as a
grinder, wire brush, hole cutter or cut-off tool.
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 sanding or polishing are not
to be performed with this power tool. Operations
for which the power tool was not designed may create
a hazard and cause personal injury.
• Do not convert this power tool to operate in a way
which is not specfically designed and specified by
the tool manufacturer. Such a conversion may result
in a loss of control and cause serious personal injury.
• Do not use accessories which are not specifically
designed and specified 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 fly apart.
• The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can-
not be adequately guarded or controlled.
• The dimensions of the accessory mounting must
fit the dimensions of the mounting hardware of the
power tool. Accessories that do not match the mount-
ing 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 undam-
aged 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. 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 applica-
tions. The dust mask or respirator must be capable
of filtrating particles generated by the particular ap-
plication. 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 fly away
and cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping surfac-
es only, when performing an operation where the
cutting tool may contact hidden 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 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 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 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 posi-
tion your body and arms 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.
