WARNING!
-Read all safety warnings and all 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 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.

.ELECTRICAL 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.
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 is an increased risk 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.
-If operating a power tool in a damp location is unavoidable, use a
ground fault circuit. Interrupter (GFCI) 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 a power tool while you are 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 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

CORDLESS DRIVER DRILL

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 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 and 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

USER MANUAL 5
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

identical replacement parts. This will ensure that the safety of the power
tool is maintained.
-Follow instruction for lubricating and changing accessories.
-Keep handles dry, clean and free from oil and grease.
