1.2.2 Torque
1.2.3 Torque Reference
For the bolts that are not marked with a specific torque other than those specified in the specific torque table, please refer
to the following table for torque tightening. If you loosen a bolt with a thread-tightening adhesive, it must be re-adhered with
a thread-tightening adhesive during assembly, using Loctite ® 243 ™. All operation shall be subject to the specification in the
repair and maintenance manual provided by the manufacturer.
* The value R (strength) indicates the material properties. The lower the value of R, the lower the torque of the bolt.

2.5. Lubrication of Steering Bearing
1. Place the vehicle on a level surface.
2. Remove the number plate, gauges, handlebars and upper
shock absorber coupling plate.
3. Lift the vehicle or lower the front forks.
4. Lubricate the steering bearings (1). Please use only high
quality grease to prevent grease loss.
5. After bearing lubrication, assemble the parts in a reverse
order.
6. If the steering bearing is damaged, please replace the
steering bearing, see (Replacement of Shock Absorber
Coupling Plate and Steering Bearing ) for steps.

2.6 Electrical Maintenance
2.6.1 Maintenance of Battery
1. Always keep the battery to be charged. Storing a depleted battery will cause permanent damage to the battery.
2. If the vehicle has not been used for more than one month, remove the battery from the vehicle to recharge it, as
described in the (Lithium Battery) section, and store it in a dry place at 0-40° C. Keep the battery charge at 30%-40%.
3. If the battery is stored for more than two months, check the battery level at least once a month and recharge the battery
if necessary. The battery needs to be charged for two hours every three months.
4. Charge the battery before inserting the battery back.
2.6.2 Fuse
【Note】To avoid short circuit, always turn the main key o when checking or replacing the fuse.
1. Open the master key to verify that the circuit is operable. Under the trim cover (1). In the fuse socket (2) , contains the
main fuse (3) and the backup fuse (4)
2. Open the fuse socket (2) and replace it with a new fuse.
3. If the fuse is fused again immediately, check the circuit.
【Note】Do not use fuses whose fusing current does not match the rated value, which may cause extensive
damage to the electrical system and cause a fire.

2.6.3 Inspection on Operation of Key Sets
1. Place the vehicle on the stand so that the rear wheels are o the ground, and then start the vehicle.
【Note】Please unlock the vehicle P gear and enter the “ready” gear
2. Test the function of all switches one by one
3. If the function of the keys is abnormal, check the key set and the circuit system

3.1.1 Caution for Operation
1. When checking the lithium battery to be used, make sure there is no abnormality in the lithium battery first.
2. The on/o test of the switch can be inspected and measured in the car body installation state of the switch.
3. After the inspection and overhaul of each part, the cable and lanyard should be passed correctly according to the
lanyard and cable wiring diagram. It is forbidden to carry out maintenance work on the three electric parts when the
whole car is in the electric state.
4. Before maintaining the high-voltage components, you must hold relevant documents and wear complete high-voltage
protective equipment.
3.1.2 Caution before Maintenance
Electric vehicle-specific voltages are high-voltage of which shall exceed 36V safety voltage. In such a case, careful
operation and backup support are required when performing rescue work. When repairing or handling the vehicle-specific
voltage system, please prepare at least the following safety protection means:
1. insulated protective equipment, including insulated gloves, protective glasses, insulated shoes, etc.
2. ABC dry powder fire extinguisher.
3. solvent-resistant protective equipment, including gas masks for organic gases, chemical-resistant rubber gloves, etc.
4. rags, towels.
【Note】If the vehicle-specific voltage cable parts are damaged and the wiring and terminals are exposed, do not
touch the exposed parts under any circumstances. In addition, do not touch the exposed wiring or terminals if you
are not sure whether the damaged is an electric motorcycle-specific voltage component.
Contacting the wiring or terminals without proper safety precautions may result in serious burns or electric shock
causing serious injury or death.
If contacting with exposed parts of electric motorcycle-specific voltage cables or voltage components is
necessary, or if there is a risk of contact, insulated protective equipment (insulated gloves, protective glasses,
insulated shoes) that can withstand electric motorcycle-specific voltage must be used.
When the person concerned is separated from the vehicle, e.g. when storing the vehicle after an accident, please
put a sticker on the body of the vehicle saying “Under Operating. Do not touch!” to avoid serious safety accidents
caused by other person inadvertently touching the vehicle.
