Noise/Vibration Information

Noise emission values determined according to
EN 62841-2-17.
Typically the A-weighted noise level of the power tool are:
95 dB(A); sound power level 106 dB(A). Uncertainty
K = 3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-17: a
2
K = 1.5 m/s .
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 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 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.

these chargers are matched to the lithium-ion battery of
your power tool.

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.
The rechargeable battery has two locking levels to prevent
the battery from falling out if the battery release button is
pressed unintentionally. The rechargeable battery is held in
place by a spring when fitted in the power tool.

Battery charge indicator

h
The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.
