Work area safety
▶ Keep your work area clean and well lit. Cluttered or dark work areas invite accidents.
▶ Do not operate the power tool 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 of the tool.
Electrical safety
▶ The plug on the supply cord of the power tool must match the power outlet. Do not change the
plug in any way. Do not use adapter plugs with earthed (grounded) power tools. Unmodified plugs
and matching power outlets reduce the risk of electric shock.
▶ Avoid body contact with earthed or grounded surfaces such as pipes, radiators, cookers, stoves
and refrigerators. There is an increased risk of electric shock if your body is grounded.
▶ Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶ Do not abuse the supply cord. Never use the supply cord for carrying, pulling or unplugging the
power tool. Keep the supply cord away from heat, oil, sharp edges or moving parts. Damaged or
tangled supply cords increase the risk of electric shock.
▶ When operating a power tool outdoors, use only extension cords of a type suitable for outdoor
use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
▶ If use of the power tool in a damp environment cannot be avoided, use a ground fault circuit
interrupter. Use of a ground fault circuit interrupter 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 the power tool may result in serious personal injury.
▶ Wear your personal protective equipment and always wear protective glasses. Depending on the
purpose for which the power tool is to be used, wearing safety equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection will reduce the risk of injury.
▶ Avoid accidental starting. Check that the power tool is switched off before you connect it to the
power supply and/or the battery and before picking it up or carrying it. Carrying power tools with
your finger on the switch or plugging in power tools that are already switched on invites accidents.
▶ Remove adjusting keys or switches before turning the power tool on. A tool or a key left attached to
a rotating part of the machine may result in personal injury.
▶ Avoid unaccustomed body positions. Maintain proper footing and balance at all times. This will
allow you to control the power tool better, even 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. The use of a dust removal system can reduce dust-related hazards.
▶ Do not lull yourself into a false sense of security and do not flout the safety rules for power tools,
even if you are familiar with the power tool after using it many times. Caress handling could cause
serious injury within fractions of a second.
Use of the power tool
▶ Do not overload the tool. Use the correct power tool for your application. The correct power tool
will do the job better and more safely within the performance range for which it is designed.
▶ Do not use a power tool if it has a faulty On/Off switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
▶ Disconnect the plug from the power outlet and/or remove a removable battery before making any
adjustments, changing accessories, or storing the tool. This precaution reduces the risk of the power
tool starting accidentally.
▶ Store idle power tools out of the reach of children . 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 carefully. Check that moving parts operate satisfactorily
and do not jam, and whether any parts are broken or so damaged that the correct operation of the
power tool is adversely affected. If parts are damaged, have the parts repaired before using of the
tool. Many accidents are caused by poorly maintained power tools.
▶ Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely
to bind and are easier to control.
