GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings and instructions. Failure to follow the
warnings and instructions may result in electric shock, fire 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.
WORK AREA SAFETY
• Keep your work area clean and well lit. Cluttered or dark areas invite accidents.
•Do not operate power tools in explosive environments, such as in the
presence of flammable 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 may cause you to lose control.
ELECTRICAL SAFETY
•Power tool plugs must match the outlet. Never modify the plug in
any way. Do not use any adapter plugs with grounded power tools.
Unmodified plugs and matching outlets will reduce the risk of electric shock.
• Avoid body contact with grounded surfaces, such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
• Do not expose power tools to rain or wet conditions. 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 the 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 interrupter (GFCl} protected supply. Use of a (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 the tool while tired or under the
influence 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 a dust mask, non-skid safety shoes, hard hat, or
hearing protection, used for appropriate conditions, will reduce personal injuries.
31224 manual_Revised_11 0628 Page 5

•Prevent unintentional starting. Ensure that the switch is in the OFF=
position before connecting to a power source and/or battery, picking up
or carrying the tool. Carrying power tools with your finger on the switch or
energizing 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 jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
•if devices are provided for the connection of dust extraction and
collection facilities, ensure that these are connected and properly used.
Use of these devices 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 more safely 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 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 children 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 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, tool application tools, 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.
31224 manual_Revised_11 0628 Page 6

BATTERY TOOL USE AND CARE
•Recharge only with the chargers specified in this manual. A charger that
is suitable for one type of battery pack may create a risk of fire when used
with another battery pack.
• Use power tools only with specifically designated battery packs. Use of
any other battery packs may create a risk of injury and fire.
• Use only the battery pack and chargers listed below.
BATTERY PACK
320.11221
CHARGER
320.10006
320.14300
320. 29497
• When the battery pack is not in use, keep it away from other metal
objects, such as 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 fire.
• Under abusive conditions, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, also seek medical help. Liquid ejected from the battery may
cause irritation or burns.
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.
• Follow instructions in the Maintenance section of this manual. Use of
parts not listed in this manual or failure to follow Maintenance instructions
may create a risk of shock or injury.
SPECiFiC SAFETY RULES FOR CORDLESS ROTARY TOOL
• Hold power tools by their insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a "live" wire will also make exposed metal parts of the tool
"live" and shock the operator.
• Use clamps or other practical way to support and secure the workpiece
to astable platform. Holding the work by hand or against your body is
unstable and may lead to loss of control.
• Accessories must be rated for at least the speed recommended on the
tool warning label. Wheels and other accessories running over the rated
speed can fly apart and cause injury.
• Disconnect all fuses or circuit breakers feeding the worksite if cutting into
existing walls or other blind areas where electrical wiring may exist
is unavoidable.
31224 manual_Revised_11 0628 Page 7

•Disconnect the battery pack from the tool or place the switch in the
off position before assembly, making any, adjustments or changing
accessories. Such preventive safety measures reduce the risk of starting the
rotary tool accidentally.
• Always hold the hand piece firmly in your hands during the start=up. The
reaction torque of the motor, as it accelerates to full speed, can cause the
shaft to twist.
•Always wear safety goggles and dust mask. Use only in well ventilated area.
Using personal safety devices and working in safe environment reduces risk of injury.
• After changing the application tools or making any adjustments, make sure
that the collet nut and any other adjustment devices are securely tightened.
Loose adjustment devices can unexpectedly shift, causing loss of control.
Loose rotating components will be violently thrown.
• Do not reach in the area of the spinning application tool The proximity of the
spinning application tool to your hand may not always be obvious.
• Carefully handle both the rotary tool and individual grinding wheels to avoid
chipping or cracking. Install a new wheel if the rotary tool is dropped while
grinding. Do not use a wheel that may be damaged. Fragments from a wheel
that bursts during operation will fly away at great velocity, possibly striking
you or bystanders.
• Never use dull or damaged application tools. Sharp application tools must
be handled with care. Damaged application tools can snap during use. Dull
application tools require more force to push the rotary tool, possibly causing
the application tool to break.
•Inspect your workpiece before cutting. When cutting irregularly shaped
workpieces, plan your work so it will not slip and pinch the application tool,
which could cause the tool to be torn from your hand. For example, when
carving wood, make sure that there are no nails or foreign objects in the
workpiece. Nails or foreign objects can cause the application tool to jump.
• Never start the rotary tool when the application tool is engaged in the
material. The cutting edge may grab the material causing loss of control.
•Avoid bouncing and snagging the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and kick-back.
•The direction of feed into the material when carving, routing or cutting is
very important. Always feed the application tool into the material in the
same direction as the cutting edge is exiting from the material (which is
the same direction as the chips are thrown). Feeding the tool in the wrong
direction, causes the cutting edge of the application tool to climb out of the work
and pull the rotary tool in the direction of this feed.
• If the application tool becomes jammed or slows down, turn the rotary tool
off with the switch. Wait for all moving parts to stop and detach the battery pack
from the rotary tool, then work to free the jammed material.
• Do not touch the application tool or collet after use. The application tool and
collet are too hot to be touched with bare hands after use.
31224 manual_Revised_11 0628 Page 8

•Do not grind or sand near flammable materials. Sparks could ignite
these materials.
•This tool is not intended for use as a dental drill, in human or veterinary
medical applications. Serious personal injury may result.
• Do not alter or misuse the tool. Any alteration or modification is a misuse and
may result in serious personal injury.
•When using the steel saws, cutoff wheels high speed cutters or
tungsten carbide cutters, always have the work securely clamped.
Never attempt to hold the work with one hand while using any of these
accessories.These wheels will grab if they become slightly canted in the
groove, and they can kickback causing loss of control resulting in serious
injury. Your second hand should be used to steady and guide the hand
holding the tool. When a cutoff wheel grabs, the wheel itself usually breaks.
When the steel saw, high speed cutters or tungsten carbide cutter grabs, it
may jump from the groove and cause lose control
• The rated speed of the application tools must be at least equal to the
maximum speed marked on the rotary tool. Application tools running faster
than their rated speed can break and fly apart.
• Never lay the rotary tool down until the application tool has come to a
complete stop. The spinning accessory may grab the surface and pull the power
tool out of your control.
• Save these instructions. Refer to them frequently and use them to instruct others
who may use this tool. Ifyou loan someone this tool, also loan them these instructions.
_IL WARNING: Wear ear protection. Exposure to noise can cause
hearing loss.

LOW-BATTERY CAPACITY iNDiCATOR
•Ifthe FuelGauge shines red when the on/off switch on the rotary tool is activated,
the battery pack power has run out and the battery pack should be recharged.
• Unlike other battery-pack types, Lithium-Ion battery packs deliver fade-free
power for their entire run time. The tool will not experience a slow, gradual
loss of power as you work. To signal that the battery pack is at the end of its
run time and needs to be charged, the power to the tool will drop quickly.
NOTICE: The LED may also flash due to an overload or high temperature (see
BATTERY PROTECTION).
BATTERY PROTECTION
The battery circuitry protects the battery pack from extreme temperature, over-
discharge, and over-charge. To protect the battery from damage and prolong
its life, the battery pack circuitry will turn off the battery pack if it becomes
overloaded or if the temperature becomes too high during use. This may happen
in extremely high torque, binding, and stalling situations. This intelligent system
will shut down your battery pack if its operating temperature exceeds 176°F
(80°C) and will begin normal operation when it returns to approximately 122°F
(50°C). The battery pack will begin normal operation when it cools down.
• The LED worklight light will begin to flash slowly if the battery circuitry
detects a momentary overload.
NOTICE: The battery can automatically reset. If the LED continues to flash rapidly,
it is indicating that the charge is substantially diminished. Place the battery into the
charger for charging. (See BATTERY CAPACITY INDICATOR, above.)
COLD WEATHER OPERATION
This Lithium-Ion battery pack will provide optimal performance in temperatures
between 32°F (0°C) and 104°F (40°C). When the battery pack is very cold, it may
"pulse" for the first minute of use to warm itself. Put the battery pack on a tool
and use the tool in a light application. After about a minute, the battery pack will
have warmed itself and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
It is not necessary to run down the battery pack charge before recharging. The
Lithium-Ion battery can be charged at any time and will not develop a "memory"
that reduces total charge when recharged after a partial discharge.
Remove the battery pack from the tool when it is convenient. "Top off" the battery
pack charge by charging it for a time before starting a big job or long period of use.
Due to Lithium-Ion fade-free properties, the only time it is necessary to charge the
Lithium- Ion battery pack is when the pack has reached the end of its charge. To
signal the end of charge, power to the tool will drop quickly. Charge the battery
pack as needed.
31224 manual_Revised_11 0628 Page 14
