Adjusting the motor shaft position
!
Skip this step if your motor shaft is already in a
12 o’clock position - from the previous step
Load 2x AA batteries into
the battery holder.
Do not try to twist the motor spindle
by hand, or using the arm. We will
show you how to use the battery
pack to rotate the motor.
Touch the red and black wires to the wires
connected to the motor. Pull one of the
wires away and check the position of the
motor shaft. Repeat until you have the
motor shaft at a 12 o’clock position.
Really close is good too.
Once done, remove the batteries from the
holder and set it aside.
