 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 6
enables stepless stroke-rate control of the switched-on
machine.
Light pressure on the On/Off switch 6 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
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.
After longer periods of work at low stroke rate, the machine
can heat up considerably. Allow the machine to cool down by
running it for approx. 3 minutes at maximum stroke rate.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature of 50 °C is exceeded, the electronic control
switches off the power tool until the temperature is in the op-
timum temperature range again.

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.
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 always use the
correct sawblade.
Switch the machine on and guide it toward the workpiece. Po-
sition the base plate 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.
Pivoting Footplate (see figure C)
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Plunge Cutting (see figures D–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.
Bosch Power Tools
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.
Flush Cuts (see figure F)
Using elastic bimetal saw blades, items still attached to a wall
(e. g. projecting building elements such as water pipes, etc.)
can be sawn off flush at the wall.
 Pay attention that the saw blade always extends be-
yond the diameter of the material being worked. There
is danger of kickback.
Position the saw blade directly against the wall and apply
some lateral pressure via the tool until the footplate faces
against the wall. Switch the power tool on and saw through
the workpiece, applying constant lateral pressure.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

 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.
 For safe and proper working, always keep the machine
and ventilation slots clean.
Clean the saw blade holder preferably with compressed air or
a soft brush. Remove the saw blade from the power tool for
this. Ensure proper operation of the saw blade holder by ap-
plying a suitable lubricant.
Heavy contamination of the machine can lead to malfunc-
tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.
