3.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
WARNING! To reduce the risk of fire, battery leakage and
personal injury, the following basic safety precautions
must be observed when battery-powered tools are used:
Read all these instructions before operating this product
and save these instructions.
3.2 Take the necessary precautions to make the
workplace safe
Keep the area above and below the cutting line free of
●
obstacles.
Wear breathing protection as conditions warrant.
●
It is recommended that protective gloves and non-slip
●
boots or shoes are worn when working outdoors.
Avoid unusual body positions. Work from a secure
●
stance and stay in balance at all times.
Concealed electric cables or gas and water pipes pre-
●
sent a serious hazard if damaged while you are work-
ing. Accordingly, check the area in which you are work-
ing beforehand (e.g. using a metal detector). Avoid
contact between your body and earthed / grounded
objects, such as pipes or radiators. External metal parts
of the tool may become live, for example, when an elec-
tric cable is sawed into inadvertently.
Unknown base materials should be examined in order
●
to avoid personal injury or the possibility of cutting
into pipes or cables. Use the right blade for the mate-
rial being cut.
Before cutting pipes, always first ensure that the pipes
●
contain no liquids. Empty the pipes if necessary. The
tool is not water or moisture proof. Liquids running
out may cause a short circuit in the tool. When cutting
pipes, hold the tool so that it is higher than the pipe
being cut.

3.3 General safety precautions

The contact shoe of the tool must be pressed against
●
the workpiece .

Use of unauthorized parts or failure to follow Mainte-
nance Instructions may create a risk of shock or injury.
Take the influences of your surroundings into account.
●
Do not expose the tool to rain or snow and do not use
it in damp or wet conditions.
Keep the grips dry, clean and free from oil and grease
●
.
Always hold the tool securely, with both hands on the
●
grips provided .
Switch on the tool only after it has been brought into
●
position where the cut is to be made but before con-
tacting the work surface.
When cutting, always guide the tool away from the
●
body.
Store tools in a safe place when not in use. When not
●
in use, tools should be stored in a dry, high place or
locked away where they are out of reach of children.
Avoid unintentional starting. Do not carry the tool with
●
your finger on the on/off switch.
Lift the tool away from the workpiece only once the
●
blade has come to a standstill.
Do not lay the tool down before the blade has come
●
to a standstill.
Never place your hands in front of or on the saw blade.
●
Always use saw blades of adequate length. To reduce
●
kick-back while sawing, the blade must always pro-
ject at least 40 mm (1.6 in) beyond the workpiece at
all times during the stroke cycle
Disconnect the tool from its battery pack when the
●
tool is not in use, during pauses between work, before
maintenance, when changing insert tools and during
transport.
Pay attention to the supply cord when using the belt
●
adaptor. It increases the risk of tripping or catching
on things.
3.3.1 Mechanical
Observe the instructions concerning care and main-
●
tenance and replacement of insert tools in good time.
Ensure that the insert tools used are equipped with the
●
correct connection end system and that they are prop-
erly fitted and secured in the chuck
