Safety
Electrical tools must be operated by authorised personnel only. Information regarding
authorised personnel is available in “Chapter 2.4”.
General safety information
WARNING
Read all safety information and instructions. Any failure to observe the safety information
and instructions can result in electric shock, re and/or serious injuries.
Retain all safety information and instructions for future reference.
The term electrical tool used in the safety instructions pertains to the mains-operated
electrical tool (with a mains cable) and battery-operated electrical tool (without a mains
cable).
Workplace safety
Keep your place of work clean and well illuminated. Untidy or non-illuminated work areas
can lead to accidents.
• Do not use the electrical tool in potentially explosive areas in which ammable liquids,
gases or dust are present. Electrical tools create sparks that can ignite dust or va-
pours.
• Ensure children and other persons are kept at a safe distance when using the electri-
cal tool. If you are distracted, you may lose control of the tool.
Electrical safety
• The electric plug of the electrical tool must t into the socket outlet. Do not modify the
plug in any way. Do not use adapter plugs together with earthed electrical tools. Un-
modied plugs and matching socket outlets reduce the risk of electric shock.
• Avoid body contact with earthed surfaces such as pipes, heaters, ovens and refriger-
ators. There is an increased risk of electric shock if your body is earthed.
• Protect your electrical tool from rain and moisture. Water ingressing an electrical tool
increases the risk of electric shock.
• Do not use the cable to carry or hang up the electrical tool or to pull the plug out of
the socket outlet. Keep the cable away from heat, oil, sharp edges and moving tool
parts. Damaged or tangled cables increase the risk of electric shock.
• When using an electrical tool outdoors, use an extension cable that is suitable for use
in outdoor areas. Using an extension lead suitable for use in outdoor areas reduces
the risk of electric shock.
• If it is not possible to avoid operating the electrical tool in a damp environment, en-
sure a residual current protective device is installed. Using a residual current protec-
tive device reduces the risk of electric shock.

Safety of persons
• Remain alert, be aware of what you are doing and use common sense when working
with the electrical tool. Do not use the electrical tool when you are tired or under the
inuence of drugs, alcohol or medication. A eeting moment of carelessness when
using the electrical tool can lead to serious injuries.
• Wear personal protective equipment and always wear safety goggles. Wearing appro-
priate personal protective equipment according to the prevailing conditions, such as
a dust mask, non-slip safety shoes, hard hat and/or hearing protection will reduce the
risk of injuries.
• Avoid starting the electrical tool unintentionally. Ensure the electrical tool is switched
o before you pick up, carry or connect the electrical tool to the power supply and/or
connect the rechargeable battery. Carrying the electrical tool with your nger on the
switch or the tool is switched on when you connect it to the power supply can lead to
accidents.
• Remove adjusting tools and spanners before switching on the electrical tool. Never
work from a ladder. A tool or key attached to the rotating tool may cause injuries.
• Avoid abnormal postures. Ensure that you have rm footing, and keep your balance
at all times. That will ensure you are able to better control the electrical tool in
unexpected situations.
• Wear suitable clothing. Do not wear loose-tting clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose-tting clothing, jewellery and long
hair can get caught up in moving parts.
• If there is an option to t dust extraction and collection devices, ensure they are
correctly connected and used properly. Using a dust extraction device can reduce risks
associated with dust.
Using and caring for the electrical tool
• Do not overload the tool. Use the correct electrical tool for your work. Using the
correct electrical tool will enable you to carry out your work better and more safely in
the specied power range.
• Do not use any electrical tool if the switch is faulty. Any electrical tool that can no
longer be switched on and o is dangerous and must be repaired.
• Remove the plug from the socket outlet and/or remove the rechargeable battery
before adjusting the tool, changing accessories or putting the tool away. These
cautionary measures prevent the electrical tool starting up unintentionally.
• When not in use, store the electrical tool out of reach of children. Do not allow
anybody to use the tool who is not familiar with the tool or has not read these
instructions. Electrical tools are dangerous in the hands of untrained users.
• Care for electrical tools appropriately. Check moving parts function awlessly and do
not jam; check if any parts are broken or damaged and impair the proper function of
the electrical tool. Ensure damaged parts are repaired before using the tool. Poorly
maintained electrical tools are the cause of many accidents. Keep cutting tools sharp
and clean. Properly maintained cutting tools with sharp edges jam less often and are
easier to use.
• Observe these instructions when using the electrical tool, accessories and tool bits.
Be aware of the working conditions and the task at hand. Using electrical tools for any
application other than that for which they were designed can lead to hazardous situa-
tions.

Service
• Allow only qualied and skilled personnel to repair your tool using only original spare
parts. That guarantees the safety of the electrical tool is maintained.
Safety information for hand saws
• Wear hearing protection when using hand saws. The eect of noise can lead to a loss
of hearing.
• Use the handles tted to the tool. Losing control of the machine can lead to injuries.
• Hold the tool using the insulated gripping surfaces when carrying out work that risks
the tool being used coming into contact with concealed power cables or its own
