The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure detailed in EN 62841
and may be used to compare power tools. They may also be
used for a preliminary estimation of vibration and noise
emissions.
The given vibration level and noise emission value represent
the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping the hands warm,
and organising workflows correctly.
Fitting
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Charging the battery

Use only the chargers listed in the technical data. Only
u
these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The following table shows examples of application tools. You can find additional application tools in Bosch's extensive range of
accessories.

The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge

by the "Electronic Cell Protection (ECP)". When the battery

To remove the battery (3), press the release buttons (2) and
pull the battery back and out of the power tool. Do not use
force to do this.
Follow the instructions on correct disposal.
Battery charge indicator
The three green LEDs on the battery charge indicator (6) in-
dicate the state of charge of the battery (3). The battery
charge indicator only lights up for five seconds after start-
up.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
Flashing light 3 x green
If no LED lights up after switching the power tool on, then
the battery is defective and must be replaced.

Selecting an application tool
Please observe the application tools intended for your power
tool.
Application tool
Material
Wood-based materials,
plastic, non-ferrous
metals
Wear protective gloves when changing tools. There is
a risk of injury when touching the application tools.
Application
Separating cuts and plunge saw cuts;
including sawing close to edges, in corners and in difficult-
to-reach areas;
example: Shortening skirting boards that are already in-
stalled or door frames, plunge cuts when adapting floor
panels
