Removing the Saw Blade (see figure B)
Swing the lever for saw blade release 4 approx. 60° in the di-
rection of the arrow and hold it in place. Pull the saw blade 1
out of the saw blade holder 18. Release the lever for saw
blade release 4 again.
Dust/Chip Extraction
 Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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. Dust can
easily ignite.
Operation
Starting Operation
Inserting the battery (see figure A)
 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.
Insert the charged battery 10 into the battery receptacle 17
until you feel it engage.
Controlling/Presetting the Stroke Rate
Soft start allows for a precise cutting start in hard materials
(e.g. steel).
Increasing or reducing the pressure on the On/Off switch 8
enables stepless stroke-rate control of the switched-on ma-
chine.
Light pressure on the On/Off switch 8 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
With the thumbwheel for stroke rate preselection 7, the
stroke rate can be preset and changed during operation.
1: Low stroke rate
6: High stroke rate
The constant electronic control keeps the stroke rate almost
constant at no-load and under load, and ensures uniform
working performance.
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.

Orbital Action Settings
The adjustable orbital action allows for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the ma-
terial being worked.
The level of orbital action can be set with rotary switch 6, even
during operation.
Orbital action switched off (level 0):
For working thin or hard material such as sheet metal or steel.
For achieving clean cutting edges.
Pendulum action level 1:
For working non-ferrous metals, hardwood, plastics or mate-
rials of medium density.
Pendulum action level 2:
For working non-ferrous metals, hardwood, plastics or mate-
rials of medium density.
For working soft materials, e. g., soft building materials, insu-
lation material, softwood, tree wood.
Pivoting and Retractable Footplate
Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.
Depending on the saw blade being used and the application,
the footplate 2 can be moved in lengthway direction in three
steps. Press the release button for the footplate 13 and slide
the footplate 2 to the required position. Release the footplate
release button 13 and check that the footplate 2 is firmly
latched. Slide the footplate 2 as required until it is firmly
latched.
To clean the saw blade holder 18, you can also completely
pull out the footplate 2 when the release button 11 is
pressed. After cleaning, slide the footplate back into its hold-
er until it engages.
 Do not press the release button 13 during operation.
You could lose control over the power tool and injure your-
self.
Switching On and Off
Switching on: Press the lock-off button 9 forward. Press the
On/Off switch 8 upward and keep it pressed.
Switching off: Release the On/Off switch 8.
To save energy, only switch the power tool on when using it.
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.
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
 Ensure that the saw blade is always longer than the di-
ameter of the workpiece, see Figure F. There is a risk of
kickback.
Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and remove them, if
required.
