LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
When no LED lights up after pressing the On/Off switch 7, the
battery is defective and must be replaced.
Replacing/Inserting the Saw Blade
Before any work on the power tool, remove the battery.
When mounting the saw blade, wear protective gloves.
Danger of injury when touching the saw blade.
When changing the saw blade, take care that the saw
blade holder is free of material residue, e. g. wood or
metal shavings.
Selecting a Saw Blade
Use only saw blades suitable for the material being worked.
An overview of recommended saw blades can be found at the
beginning of these instructions. Use only ½" universal shank
saw blades. The saw blade should not be longer than required
for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure B)
Turn the locking sleeve 3 approx. 90° in the direction of the
arrow and hold. Push the saw blade 1 into the saw blade hold-
er 13. Release the locking sleeve 3 again.
Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.
For certain work, the saw blade 1 can also be turned through
180° (with the teeth pointed upwards) and re-inserted again.
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.
Bosch Power Tools
Operation
Capacity
≥2/3
Starting Operation
≥1/3
Inserting the battery
<1/3
Use only original Bosch lithium-ion batteries with the
Reserve
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 switch on the power tool, 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
enables stepless stroke-rate control of the switched-on ma-
chine.
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.
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.
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.
