Bosch Power Tools
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
cutting.
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 quick-
er operational progress, e. g., for
coarse cuts in wood.
Switching On and Off
To
start
the machine, press the On/Off switch
7
and keep it pressed.
To switch off the machine,
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
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.
Protection Against Deep Discharging
The lithium ion battery is protected against
deep discharging by the “Electronic Cell Protec-
tion (ECP)”. When the battery is empty, the ma-
chine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Working Advice
Pivoting Footplate (see figure D)
Due to its movability, the adjustable footplate
2
adapts to the required angular position of the
surface.
Tips
f
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
applying uniform contact pressure and feed. Af-
ter 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 E)
f
The plunge cutting procedure is only suita-
ble for treating soft materials such as wood,
plaster board or similar! Do not work metal
materials with the plunge cutting proce-
dure!
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 along-
side the desired cutting line.
For certain work, the saw blade
1
can also be in-
serted turned through by 180° and the sabre
saw can be guided accordingly in a reversed
manner.
Flush Cuts (see figure F)
Using elastic bimetal saw blades, items still at-
tached to a wall (e. g. projecting building ele-
ments such as water pipes, etc.) can be sawn off
flush at the wall.
f
Pay attention that the saw blade always ex-
tends beyond the diameter of the material
being worked. There is danger of kickback.
