 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation

Starting Operation

Inserting the battery
 Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
To protect the machine against unintentional starting, set the
stroke speed selector switch 6 to the centre position. Insert
the charged battery 9 from the front into the handle of the
power tool. Push the battery completely into the handle until
the red stripe can no longer be seen and the battery is secure-
ly locked.
Changing the Stroke Speed Setting
The stroke speed setting of the power tool can be changed
with the stroke speed selector switch 6. However, this is not
possible when the On/Off switch 7 is pressed.
Stroke speed selector switch 6 – central position:
The safety lock is activated.
The On/Off switch 7 is blocked and the machine
is secured against being switched on uninten-
tionally.
Stroke speed selector switch 6 – left:
1st gear, low stroke speed.
The low stroke speed is suitable for sawing hard
materials such as steel, non-ferrous metal, hard
plastics or for precision cuts in wood and plunge
cutting.
The low stroke speed enables sawing with less
vibrations.
Stroke speed selector switch 6 – right:
2nd gear, high stroke speed.
The high stroke speed is suitable for sawing soft
materials.
The high stroke speed enables quicker opera-
tional progress, e.g., for coarse cuts in wood.

Switching On and Off
To switch on the power tool, press the On/Off switch 7 and
keep it pressed.
To switch off the power tool, release the On/Off switch 7.
To save energy, only switch the power tool on when using it.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 7 en-
ables stepless stroke-rate control of the switched-on machine.
The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.
Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.

Working Advice

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
Pivoting Footplate (see figure D)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Tips
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and remove them, if
required.
Switch the machine on and guide it toward the workpiece. Po-
sition the footplate 2 onto the surface of the work and saw
through the material applying uniform contact pressure and
feed. After completing the working procedure, switch the ma-
chine off.
If the saw blade should jam, switch the machine off immedi-
ately. Widen the gap somewhat with a suitable tool and pull
out the machine.
Plunge Cutting (see figure E)
 The plunge cutting procedure is only suitable for treat-
ing soft materials such as wood, plaster board or simi-
lar! Do not work metal materials with the plunge cut-
ting procedure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate 2 onto the
workpiece and switch on. For power tools with stroke speed
control, set the maximum stroke speed. Press the power tool
firmly against the workpiece and allow the saw blade to slowly
plunge into the workpiece.
As soon as the footplate 2 fully lays on the surface of the work-
piece, continue sawing alongside the desired cutting line.
For certain work, the saw blade 1 can also be inserted turned
through by 180° and the sabre saw can be guided accordingly
in a reversed manner.
