Stroke speed selector switch 6 – central posi-
tion:
The safety lock is activated.
The On/Off switch 7 is blocked and the
machine is secured against being
switched on unintentionally.
Stroke speed selector switch 6 – left:
1. 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 cut-
ting.
The low stroke speed enables sawing
with less vibrations.
Stroke speed selector switch 6 – right:
2. Gear, high stroke speed.
The high stroke speed is suitable for
sawing soft materials.
The high stroke speed enables quicker
operational progress, e. g., for coarse
cuts in wood.
Switching On and Off
To start 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.
Controling the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 7 enables stepless stroke-rate
control of the switched-on machine.
The required stroke rate is dependent on the ma-
terial and the working conditions and can be de-
termined 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 aluminum.
Bosch Power Tools
Protection Against Deep Discharging
The lithium ion battery is protected against deep
discharging by the "Electronic Cell Protection
(ECP)". When the battery is empty, the machine
is switched off by means of a protective circuit:
The inserted tool no longer rotates.

Working Instructions

Pivoting Footplate (see figure C)
Due to its movability, the adjustable footplate 2
adapts to the required angular position of the
surface.
Tips
When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material 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. Position the footplate 2 onto the sur-
face of the work and saw through the material ap-
plying uniform contact pressure and feed. After
completing the working procedure, switch the
machine off.
If the saw blade should jam, switch the machine
off immediately. Widen the gap somewhat with a
suitable tool and pull out the machine.
Plunge Cutting (see figure D)
The plunge cutting procedure is only suit-
able for working soft materials such as
wood, plaster board or similar! Do not work
metal materials with the plunge cutting pro-
cedure!
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 maxi-
mum 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 sur-
face of the workpiece, continue sawing alongside
the desired cutting line.
