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 product is 72 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed
80 dB(A).

GSB 12 VE-2/GSB 14,4 VE-2/GSB 18 VE-2:
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working period.

, Uncertainty
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the to-
tal working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.

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 cy-
cles.
To remove the battery 7 press the unlocking but-
tons 6 and pull out the battery downwards. Do
not exert any force.
