General power tool safety instructions
WARNING Read all the safety notes, instructions, illustrations and
technical details supplied with this power tool. Failure to follow the safety
notices and instructions may result in an electric shock, fire and/or severe
injury.
Save all warnings and instructions for future reference.
The term “power tool” used in the safety instructions refers to mains-operated
power tools (corded) and battery-powered power tools (cordless).
Work area safety
a) Keep your work area clean and well lit. Cluttered or 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 or fumes.
c) Keep children and bystanders away while operating a power
tool. If you are distracted, you could lose control of the power tool.

Safety
7
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.
d) Do not use the cord for improper purposes such as for carrying
the power tool, for hanging it up or for pulling or unplugging
it from the socket. Keep cord away from heat, oil, sharp edges
and moving parts.
Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use only extension cords
that are suitable for outdoor use. Use of a cord suitable for outdoor
use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use
a residual current device (RCD) protected supply.
Use of an RCD
reduces the risk of electric shock.
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 personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
c) Prevent unintentional starting. Make sure that the power tool is
turned off before you connect it to the power supply, pick it up
or carry it. Carrying power tools with your finger on the switch or
connecting the power tool to a power supply while the switch is set to
‘on’ may lead to accidents.

Safety
8
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) Take care to keep a normal body position. Maintain a stable
stance 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 jewellery. Keep
your hair and clothing away from moving parts.
Loose clothes,
jewellery or long hair can be caught in moving parts.
g) If there is an option for installing dust suction devices and dust
containers, these should be attached and used correctly. Use of
dust collection can reduce dust-related hazards.
h) Do not be lulled into a false sense of security and ignore the safety
rules for power tools, even if you are well acquainted with power
tools, having used them frequently.
Using power tools without due
care and attention can cause serious injuries in a split second.
Power tool use and care
a) Do not overload 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) Disconnect the plug from the power source before making any
adjustments, changing attachments or storing the power tool.
Such preventive safety measures reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of children. Do not let any
individual who is not familiar with the power tool or who has not
read these instructions operate this power tool.
Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools and insertion tools with care. Check for
misalignment or binding of moving parts, breakage of parts and
any other condition that may affect the power tool’s operation. If
any parts of the power tool are damaged, have them repaired
before use. Many accidents are caused by poorly maintained power
tools.

Safety
9
f) Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and fitted tools 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.
h) Keep handles and handle surfaces dry, clean and free from oil
and grease. Slippery handles and handle surfaces will prevent you
from operating and controlling the power tools safely in unforeseen
situations.
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.
Safety instructions for reciprocating saws
− For your own safety, only operate the saw after you have read the safety
instructions.
− Hold the saw only by the insulated handle surfaces when performing
work where the fitted tool may contact hidden power lines or its own
cable. Contact with a live wire may send current up exposed metal parts
of the power tool and give the operator an electric shock.
− Fasten and secure the workpiece to a stable surface using clamps or in
another manner. If you only hold onto the workpiece with your hand or put
it against your body, it will remain unstable and could lead to loss of control.
− Only use sharp saw blades in perfect condition. Immediately replace any
cracked, bent or dull saw blades.
− Adapt fitted tools and the stroke rate to the material. Ensure an even feed
motion.
− Make sure that the permissible stroke rate of the fitted tool is at least as
high as the maximum number specified on the saw. Accessories that
move faster than permissible may break and be projected.
− Only operate the saw if the saw shoe is mounted. When working, the saw
shoe must always be positioned on the work piece.

Safety
10
− Only run the saw up to the work piece once it has been switched on.
− Never process material containing asbestos. Use a protective mask and
dust extractor for other fibrous material.
− Do not slow down the saw blade by applying side pressure.
− Use clamping devices to secure the work piece and prevent slippage.
− During operation, always guide the saw with both hands and assume a
stable posture.
− Always route the mains cable away from the working space.
− Do not expose the saw to moisture. It must not get damp and must not be
operated in a damp environment.
