SAFETY GUIDELINES:
WARNING!
Safety symbols in this Instruction Manual are used to flag possible dangers. The safety
symbols and their explanations require your full understanding. The safety warnings do not,
by themselves, eliminate any danger, nor are they substitutes for proper accident prevention
measures.
WARNING!
This Safety Alert Symbol indicates caution, warning, or danger. Failure to obey a safety
warning can result in serious injury to yourself or others. To reduce the risk of injury, fire, or
electric shock, always follow the safety precautions.
KNOW YOUR TOOL
To operate this tool, carefully read this Instruction Manual and all labels affixed to the screwdriver
before using. Keep this instruction manual available for future reference.
IMPORTANT
This tool should only be serviced by a qualified service technician. For more information, call the toll
free helpline at 1-800-689-9928.
READ ALL INSTRUCTIONS THOROUGHLY.

GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
Read all safety warnings, instructions, illustrations and specifications provided with
this power tool. Failure to follow all instructions listed below 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 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.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
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 supply. Use of an 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 a 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 jewellery. Keep your hair and clothing
away from moving parts. Loose clothes, jewellery 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 dust collection can reduce dust-related
hazards.

• Do not let familiarity gained from frequent use of tools allow you to become complacent
and ignore tool safety principles. A careless action can cause severe injury within a fraction of a
second.
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 remove the battery pack,
if detachable, 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 and accessories. 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
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.

• Do not use a battery pack or tool that is damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour 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
temperature above 130°C (265°F) 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.
ADDITIONAL SAFETY GUIDELINES FOR THE SCREWDRIVER
• Hold the power tool by insulated gripping surfaces, when performing an operation
where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may
make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• The label on your tool may include the following symbols. The symbols and their
definitions are as follows:
V ..................... Volts
A ..................... Amperes
Hz ................... Hertz
W .................... Watts
min ................. Minutes
or d.c .............. Direct current
n0................... No-load speed
…/min or …min-1 ................... Revolutions or reciprocations per minute
RPM ............... Revolutions per minute
.............. WARNING – To reduce the risk of injury, user must read instruction manual.
.............. WARNING – To reduce the risk of injury always wear eye protection.
.............. WARNING – To reduce the risk of injury always wear ear protection.
• For best results, your battery tool should be charged, stored and used in a location
where the temperature is more than 5°C (41°F) but less than 40°C (104°F). Do not store
outside or in vehicles.
