GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings and instructions. Failureto 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 work area clean and well lit. Cluttered or dark areas invite accidents.
•Do not operate power tools in explosive atmospheres, 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 can 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 adaptor plugs with earthed (grounded) power tools.
Unmodified 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 isan increasedrisk of electric
shock if your body is earthed or 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, pullingor
unpluggingthe 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 interrupter (GFCI) protected power 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 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 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 finger on the switch or
energizing in 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 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 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 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'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, 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.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specified by the manufacturer. 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.
• 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 fire.
• Under abusive conditions, liquid may be ejected from the battery;
avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, additionally 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 willensurethat the safety of the power
tool is maintained.
Follow instructions in the Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance instructions may create
a risk of shock or injury.
SPECIFIC SAFETY RULES FOR DRILL DRIVER
•Know your drill/driver. Read operator's manual carefully. Learn the
applications and limitations, as well as the specific potential hazards related
to this tool. Following this rule will reduce the risk of electric shock, fire or
serious injury.
• Hold power tools by their insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden wiring. If a
cutting accessory contacts a "live" wire, it may make exposed metal parts
of the power tool "live" and could give the operator an electric shock.
•Use auxiliary handle(s), if supplied with the tool. Loss of control can
cause personal injury.
