General power tool safety instructions
WARNING Read all the safety notes, instructions, illustrations and tech-
nical 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.
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.

Safety
10
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 enter-
ing 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. Ensure the switch is in the off-po-
sition before connecting to power source and/or battery pack,
picking up or carrying the tool. 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.
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 pow-
er 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.

Safety
11
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 dan-
gerous and must be repaired.
c) Disconnect the plug from the power source and/or remove the
rechargeable battery from the power tool before making any
adjustments, changing insertion tools or storing the power tool.
Such preventive safety measures reduce the risk of starting the pow-
er 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 mis-
alignment 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.
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.

Safety
12
g) Use the power tool, accessories and fitted tools etc. in accordance
with these instructions, taking into account the working con-
ditions 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.
Cordless tool use and care
a) Only charge the rechargeable batteries with chargers recom-
mended by the manufacturer. Chargers designed for a particular
rechargeable battery type pose a risk of fire if used with other types
of rechargeable battery.
b) Only use the rechargeable batteries designated for use in power
tools. Using other rechargeable batteries may result in injury and a
risk of fire.
c) Keep the unused rechargeable battery away from paper clips,
coins, keys, nails, screws or other small metallic objects that
could bridge the contacts. A short circuit between the contacts of
the rechargeable battery could result in burns or fire.
d) If used improperly, liquid may leak out of the rechargeable bat-
tery. Avoid coming into contact with it. Rinse with water in the
event of accidental contact. If liquid comes into contact with your
eyes, also seek medical attention. Fluid leaked from the rechargea-
ble battery may cause skin irritations or burns.
e) Do not use a damaged or modified rechargeable battery. Dam-
aged or modified rechargeable batteries can be unpredictable and
may result in fire, an explosion or a risk of injury.
f) Do not expose a rechargeable battery to fire or excessively high
temperatures. Fire or temperatures above 130 °C may cause an
explosion.
g) Follow all instructions for charging and never charge the battery or
cordless tool outside of the temperature range indicated in the user
manual. Improper charging or charging outside of the permitted tem-
perature range may damage the battery and increase the risk of fire.

Safety
13
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.
b) Never perform maintenance on damaged rechargeable batteries.
Only the manufacturer or authorised service companies may perform
maintenance on rechargeable batteries.
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. 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 proper 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.
− 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.

Safety
14
− Do not expose the saw to moisture. It must not get damp and must not be
operated in a damp environment.
− Wear a protective breathing mask and protective goggles when perform-
ing dusty work. Do not smoke when performing dusty work and avoid
open fire.
− Wear protective gloves when handling saw blades and rough materials to
cut injuries.
− Wear ear protection when performing work.
− Do not leave any tool keys inserted.

Operation
19
NOTICE!
Risk of damage!
Using the product incorrectly may damage the product.
− Select a moderate cutting speed to avoid overloading the battery and
product.
− Check the area behind the workpiece. Foreign bodies or materials lying
around may get caught in the saw and lead to the product becoming
blocked.
− Check workpieces made of wood for foreign bodies such as nails or screws
before beginning work.
NOTICE!
Risk of damage!
Insufficiently secured workpieces may slip during processing and be perma-
nently damaged.
− Ensure that the workpiece is sufficiently fixed into place.
− Use the appropriate clamping devices e.g. vices to secure the workpiece.
The product is operated via the On/Off switch 11 . The On/Off switch serves to switch
the product on and off. To do this you need to hold down or release the On/Off switch.
The On/Off switch also serves to regulate the stroke rate steplessly.
• The product is fitted with a switch lock 1for the On/Off switch.
The switch lock is located in a separate pressure switch at the side
of the product. This prevents the product from being switched on
inadvertently. The switch lock must be pressed before activating
the On/Off switch.
• The stroke rate can be regulated steplessly by adjusting the
pressure on the On/Off switch accordingly. Lightly pressing the
On/Off switch leads to a low stroke rate. The stroke rate rises as
you increase the pressure, as does the speed of movement of the
clamped saw blade.
