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 button and pull the battery out. Do not use force to do
this.
Battery Charge Indicator on the Power Tool
The battery charge indicator on the power tool indicates the
state of charge for a few seconds when the on/off switch is
half or fully pressed.

The three LEDs in the battery charge indicator flash quickly
when the overload protection has been triggered.If only the
middle LED is flashing quickly, then the temperature of the
rechargeable battery or the power tool is outside of the oper-
ating temperature range.Allow the battery and the power
tool to cool.
Battery Charge Indicator on the Rechargeable
Battery
Note: Not all battery types have a battery charge indicator.
The LEDs on the battery charge indicator on the re-
chargeable battery indicate the state of charge of the bat-
tery. For safety reasons, it is only possible to check the char-
ging status when the power tool is at a standstill.
Press the button for the battery charge indicator on the re-
chargeable battery to show the state of charge. This is also
possible when the rechargeable battery is removed.

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.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Assembly
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
Auxiliary Handle (see figure A)
The auxiliary handle enables the tool to be used safely and
more comfortably.
Screw the auxiliary handle into the thread on the left or right
of the machine head depending on how you are working.
