The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ac-
cessories or is poorly maintained, the vibration level and
noise emission value may differ. This may significantly in-
crease the vibration and noise emissions over the total work-
ing 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 accessories, keeping their hands warm, and
organising workflows correctly.
Rechargeable battery
Bosch sells some cordless power tools without a re-
chargeable battery. You can tell whether a rechargeable bat-
tery is included with the power tool by looking at the pack-
aging.
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: Lithium-ion rechargeable batteries are supplied par-
tially charged according to international transport regula-
tions. To ensure full rechargeable battery capacity, fully
charge the rechargeable battery before using your tool for
the first time.

Inserting the Battery
Push the charged battery into the battery holder until it
clicks into place.
Removing the Battery
To remove the rechargeable battery, press the battery re-
lease buttons and pull the battery out. Do not use force to
do this.
Battery charge indicator
The battery charge indicator indicates the state of charge for
a few seconds when the on/off switch is pressed halfway.

2× continuous green light
1× continuous green light
1× flashing green light
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If there is an extreme overload, the power tool
switches off until the optimal operating temperature range is
reached again.
This status is indicated by the three battery charge indicator
LEDs flashing in a chase sequence. The LEDs turn off if the
power tool has reached the optimum operating temperature
again.
Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
