6.3.1 Installing the gearhead
To assemble the motor and the gearhead, adjust the assembling faces together in such a way as
shown in below figure and turn slowly to complete the assembly. When doing the assembly,
special care should be taken neither to exert excessive force on the motor shaft nor to hit inside
of the gearhead. Otherwise, the gear will get damaged, resulting in an abnormal noise and a
shortened life time of the motor
