GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert, and knowing how your power tool works.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING: Do not operate this unit until you read this instruction manual for safety,
operation and maintenance instructions. Failure to follow all instructions listed below may
result in electric shock, fire, and/or serious personal injury.
WORK AREA SAFETY
Keep your work area clean and well lit. Cluttered benches and 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 bystanders, children, and visitors away while operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SATETY
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.
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 safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or
hearing protection must be used for appropriate conditions.
•Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts.
•Avoid accidental starting. Be sure switch is off before connecting to power source and/ or battery
pack, pick 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. Proper footing and balance enable
better control of the power tool in unexpected situations.
6
•If devices are provided for the connection of dust extraction and collection facilities, ensure theses
are connected and properly used. Use of dust collection can reduce dust-related hazards.
POWER TOOL USE AND CARE
•Do not force 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 is designed.
•Do not use the power tool if switch does not turn it on or off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
•Disconnect the plug from the power source before making any adjustments, changing accessories, or
storing the power tool. Such preventive safety measures reduce the risk of starting the power tool
accidentally.
•Store idle power tools out of reach of children and other untrained persons. Power tools are
dangerous in the hands of untrained users.
•Maintain power tools with care. Keep cutting tools sharp and clean. Properly maintained power tools,
with sharp cutting edges are less likely to bind and are easier to control.
•Check for misalignment or binding of moving parts, breakage of parts, and any other condition that
may affect the power tools operation. If damaged, have the power tool serviced before using.
•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 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 another battery packs my
create a risk of injury and fire. Use only POWERSMART battery (Model#PS76018B)
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 extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact
with your skin, wash immediately with soap and water, then neutralize with lemon juice or vinegar. If
liquid gets into your eyes, flush them with clean water for at least 10 minutes, then seek immediate
medical attention. Following this rule will reduce the risk of serious personal injury.
SERVICE
•Tool service must be performed only by qualified repair personnel. Service or maintenance
performed by unqualified personnel could result in a risk of injury.
•When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may
create a risk of electric shock or injury.

SPECIFIC SAFETY RULES FOR CORDLESS IMPACT DRIVER
Use auxiliary handles supplied with the tool. Loss of control can cause personal injury. (if supplied)
Hold the tool firmly.
Hold 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.
Always be sure you have a firm footing. Be sure no one is below when using the tool in high
locations.
Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
Disconnect battery pack from tool before making any assembly, adjustments or changing accessories.
Such preventive safety measures reduce the risk of starting the tool accidentally.
Do not grasp the tool or place your hands too close to the spinning chuck or drill bit. Your hand may
be lacerated.
When installing a bit, insert the shank of the bit well within the chuck. If the bit is not inserted deep
enough, the grip of the chuck over the bit is reduced and the loss of control is increased. After bit
insertion, pull on bit to ensure it is locked.
Do not use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to
bind in the workpiece.
Do not touch the bit or the workpiece immediately after operation. They may be extremely hot and
could burn your skin.
Save these instructions. Refer to them frequently and use them to instruct others who may use this
tool. If you loan someone this tool, loan them these instructions also to prevent misuse of the product
and possible injury.

OPERATING TIPS
Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the
tool to the extent that the bit will not slip off the screw and turn the tool on to start operation.
CAUTION:
•Use the proper bit for the head of the screw/bolt that you wish to use.
•Hold the tool pointed straight at the screw.
•If the impact force is too strong or you tighten the screw for too long time, the screw or
the point of the driver bit may be over stressed, stripped, damaged, etc. Before starting your job, always
perform a test operation to determine the proper fastening time for your screw.
Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off.
The torque depends on the impact duration. The maximum achieved torque results from the sum of all
individual torques achieved through impact. The maximum torque is achieved after an impact duration of
3-5 seconds. After this duration, the tightening torque is increased only minimally.
The fastening torque is affected by a wide variety of factors including the following. After fastening,
always check the torque with a torque wrench.
•Strength properties of the screws/nuts.
•Type of backing (washer, disc spring, seal).
•Strength properties of the material being screwed/bolted together.
•Lubrication conditions at the screw/bolt connection.
IMPORTANT CHARGING NOTES
WARNING: Battery packs are shipped in a low charge condition to prevent possible
problems. Therefore, you should charge them before first use.
•Use only POWERSMART battery charger (Model#PS76018C)
