Assembly
Battery charging (see figure A)
Use only the chargers listed on the accessories page.
u
Only these chargers are matched to the lithium-ion bat-
tery 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.
Bosch Power Tools
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 (6), press the release button (5) and
pull the battery downwards out of the power tool. Do not
use force to do this.
The battery features NTC temperature monitoring, which
only permits charging in a temperature range between 0 °C
and 45 °C. This achieves a long battery life.

GAX 18V-30 The working procedure is divided into two phases: Screwing
in and tightening (impact mechanism in action).
The impact mechanism is activated as soon as the screwed
connection becomes tightened, exerting a load on the mo-
tor. The impact mechanism then converts the power of the
motor to steady rotary impacts. When loosening screws or
nuts, the process is reversed.
