Selecting the rotation direction
(figure 9).
Under no-load, the application tool rotates
counterclockwise; when applying pressure,
the rotation direction switches to clockwise,
and when pulling back, it switches to counter-
clockwise again.
To avoid accidental starting, e. g., during
transport, set the rotation selector switch to
the centre position.
Handling the battery.
Store, operate and charge the battery only
using FEIN battery chargers within the oper-
ating-temperature range between 5°C –
45°C (41°F – 113°F). At the beginning of the
charging procedure, the battery temperature
must be within the battery operating-temper-
ature range.
Battery charge-control indicator
(figure 10).
Press the button to activate the LED indica-
tion.
The real percentage of the battery charge
condition is only indicated when the power
tool motor is stopped.
The electronics automatically switch off the
motor prior to the battery being deep dis-
charged.
