Maintenance and Repair of Electric Motors
Operation
1) During operation, if the controller fails to function properly, do not start the vehicle directly.
2) There should be no intermittent or abnormal sounds or vibrations during operation.
3) Before starting the vehicle, ensure that the gear oil (GL-4 85W-90, approximately 100 mL) has
been added.
Maintenance
Perform the first maintenance check when the new vehicle has ridden 300 km, primarily to inspect
the break-in of components and the condition of fasteners.
Perform the second maintenance at 1000 km, in addition to regular checks, replace the gearbox oil,
clean the iron filings from the drain plug, remove residual iron filings from the gearbox, clean dust
and foreign matter around the vent plug to keep it clean, and then check sensor signals and tighten
bolts. According to the maintenance requirements of the all-terrain electric motorcycle, conduct
maintenance checks on the assembly as follows:
a. Check the sensor signals of the motor; if signal wires are found damaged, replace them promptly.
b. Inspect the suspension of the assembly and check if all component bolts are loose; tighten
immediately if any are loose.
c. Check the sealing surfaces and oil seals of components, replacing damaged oil seals promptly to
ensure sealing performance.
d. Clean foreign matter around the exhaust plug and keep the exhaust plug open.
e. According to the riding conditions of the all-terrain electric motorcycle, replace the gear oil and
clean iron filings every three months or 5000 km (whichever comes first from the two options).
