Removing the Saw Blade (see figure C)
Turn the locking sleeve 3 approx. 90° in the direction of the
arrow and hold. Remove the saw blade 1.
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
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.
Push the lock-off button 6 leftward to protect the power tool
against accidental switching on.
Insert the charged battery 12 into the handle until it can be
felt to engage and faces flush against the handle.
Switching On and Off (see figure D)
Push the lock-off button 6 rightward.
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.
Afterwards, push the lock-off button 6 leftward again.
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 ena-
bles 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.
Temperature Control/Overload Protection Indicator
The red LED indicator 10 will help you in protecting the bat-
tery against overheating and the motor against overloading.
When the LED indicator 10 continuously lights up red, the
temperature of the battery is too high and the machine
switches off automatically.
– Switch the power tool off.
– Allow the battery to cool down before continuing to work.
Bosch Power Tools
The LED indicator 10 flashes red, the power tool is blocked
and switches off automatically.
– Remove the power tool from the workpiece.
As soon as the blockage is corrected, the power tool will
continue to work at the set stroke rate.
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 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 remove them, if
required.
Switch the machine on and guide it toward the workpiece.
Position 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
machine 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.
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
0 °C and 50 °C. As an example, do not leave the battery in the
car in summer.
