4.4. Tighten the bolts ②, ③, ④, ⑤ and ⑥ in turn with a torque of 6.3 foot-pound（9N·m).（see
Fig 12-15）
4.5. Install the electric motor wires. Ensure that they are connected with the right terminals of the
electric motor and that the terminals orientation are right. Please refer to the wiring diagram on
page 9-7. Tighten the clamp nuts of the terminal with a torque of 7.5 foot-pound（10.2N·m).
4.6. Fasten the armature wire and electric excitation wire with binding tape so as to prevent the
electric motor wire from contact with the electric motor or the driving axle when the electric
vehicle is in operation.
4.7. Connect 3-wire speed sensor wires and electric vehicle harness.
5. In case the wheels are removed, mount them and tighten the wheel nuts with fingers.
6. Turn the TOW/RUN switch to the TOW position. To connect the battery, first connect the positive
electrode（＋）cable， then tighten it with a torque of 110 inch pound（12.4N·m). Apply the antirust
oil on all connecting terminals to minimize future corrosion.
7. Set the Tow/Run switch at the RUN position.
8. Inspect the electric vehicle for normal operation.
• Ensure the electric vehicle is moving forward when the Forward/Reverse switch is at FORWARD
position.
• Ensure the electric vehicle is moving backward when the Forward/Reverse switch is at REVERSE
position. When the Forward/Reverse switch is at REVERSE position, the backing-up buzzer
should give off an audible alarm.
9. Ensure the electric vehicle is not moving when the Forward/Reverse switch is at NEUTRAL
position.
