1. GENERAL SAFETY INSTRUCTIONS
WARNING
When using electric tools, basic safety precautions, including the following, should
always be followed to reduce the risk of fire, electric shock and personal injury.
Read all instructions before operating this product and keep the instructions for
future reference.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit. Cluttered and dark areas invite
accidents.
b) 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 of fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering
a power tool will increase the risk of electric shock.

- 6 -
3) Personal safety
a) 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.
b) Use safety equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off position
Before installing the storage battery. Carrying power tools with your finger
on the switch invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) 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.
g) 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.

- 7 -
4) Power tool use and care
a) 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.
b) 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.
c) Detach the battery from the wrench before making any adjustments,
changing accessories, or storing power tools.
d) 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.
e) Maintain power tools. 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 repaired before use.
Many accidents are caused by poorly maintained power tools.
f) Use the power tool, accessories and tool bits etc., in accordance with
these instructions and in the manner intended for the particular type of
power tool, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from intended
could result in a hazardous situation.
5) Service
a) 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.
