Noise/Vibration Information
Measured values determined according to EN 60745.
GSR 12 VE-2 / GSR 14,4 VE-2 / GSR 18 VE-2:
Typically the A-weighted sound pressure level of the
machine is 72 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 85 dB(A).

WARNING
this information sheet has been meas-
ured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with
another.
The vibration emission level will vary because of the
ways in which a power tool can be used and may
increase above the level given in this information sheet.
This could lead to a significant underestimate of expo-
sure when the tool is used regularly in such a way.

Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given period
of work should also take into account the times when
the tool is switched off and when it is running but not
actually doing the job. This may significantly reduce the
exposure level over the total working period.
Assembly
Battery Charging
A battery that is new or has not been used for a longer
period does not develop its full capacity until after
approx. 5 charging/discharging cycles.
To remove the battery 8 press the unlocking buttons 7
and pull out the battery downwards. Do not exert any
force.
The battery is equipped with a NTC temperature con-
trol which allows charging only within a temperature
range of between 0 °C and 45 °C. A long battery serv-
ice life is achieved in this manner.
A significantly reduced working period after charging
indicates that the battery is used and must be replaced.
Observe the notes for disposal.
Auxiliary Handle (GSR 18 VE-2 /
GSB 18 VE-2) (see figure A)
Operate your machine only with the auxiliary
handle 6.
The auxiliary handle 6 can be set to any position for a
secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 6 in coun-
terclockwise direction and swivel the auxiliary handle 6
to the desired position. Then retighten the bottom part
of the auxiliary handle 6 by turning in clockwise direc-
tion.
The clamping band 12 of the auxiliary handle must be
seated in the corresponding groove.
