1.2 Motor and Electronic Module 1.4 Operating Instructions
The two-stage axial fan is driven by an electronically
commutated (EC) motor. Unlike other (DC) motors 1.4.1 Switching On

the electric motor are managed electronically. This
enables a high torque to be achieved while 1
minimizing wear, reducing the space required and
keeping the noise level low.
An electronic module converts the battery voltage to
the voltage required by the motor and controls the
motor in response to the position of the trigger
switch. The electronic module monitors the motor's

Charging principle
The charger charges the battery in two stages. The
battery is first charged at a constant current up to a
preset voltage limit. (Capacity of battery about
80%). The charger then switches over to charging at
a constant voltage. The charge current is reduced
automatically until it drops below a given minimum
or the preset total charge time is exceeded. The
charger then switches itself off automatically.
(Capacity of battery about 100%).
