the right side of the Hummingbird Electric axle. Then connect the charger plug to an outlet (see 2.3, Figure
5). Check the mains voltage: it must match the one indicated below the charger itself! The charging
procedure will start as soon as the charger is connected both to Hummingbird Electric and to the mains.
While charging, the LED located on the charger is red. The system is deactivated while charging the battery
pack.

from the mains and from Hummingbird Electric. Be careful when touching the charger, It can heat up
considerably while charging. Remember to seal the connector on Hummingbird Electric with the proper
protection cap (see Figure 1). Using Hummingbird Electric without the protection cap will void the warranty.
