Noise/Vibration Information

Noise emission values determined according to
EN 62841‑2‑11.
Typically, the A-weighted sound pressure level of the power
tool is 75 dB(A). Uncertainty K = 5 dB. The noise level when
working can exceed the volume stated. Wear hearing pro-
tection!
Vibration total values a (triax vector sum) and uncertainty K

determined according to EN 62841‑2‑11:
Cutting boards with saw blade T 111 C:

a = 4.5 m/s , 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.

Implement additional safety measures to protect the oper-

ator from the effects of vibration, such as servicing the

Battery Charging (see figure A)
Use only the chargers listed in the technical data. Only

these chargers are matched to the lithium-ion battery of
your power tool.
Note: The battery is supplied partially charged. To ensure

full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
GAL 12...
The lithium-ion battery can be charged at any time without

reducing its service life. Interrupting the charging process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
To remove the battery (1), press the release button (2) and
pull the battery downwards out of the power tool. Do not
use force to do this.
Battery charge indicator
The three green LEDs of the battery charge indicator (4) in-
dicate the state of charge of the battery (1). The battery
charge indicator only lights up for five seconds after start-
up.

If no LED lights up after switching the power tool on, then
the battery is defective and must be replaced.
