Precautions taken during break in period:
1. During the break in period, replace the oil with Standard
15w-40 or synthetic 5w-40 engine oil and clean the oil filter
screen every 300-500 miles.
2. Regularly check for loose electrical connections, and tighten if
found.
3. Regularly check to make sure that the engine, the drive train,
and the braking system does not overheat. Make sure that
there is enough lubricating oil on each lubricated part. If any
overheating occurs, the cause should be found and rectified
immediately.
4. Regularly check the tightness of the drive belt, the free travel
of the front and rear brakes, throttle grip and the handle bar
movement. Adjust them if necessary.
5. During the break-in period, only operate the vehicle after the
engine is well warmed up. First run it at low speed for 1~2
miles, and then run it at higher speeds.
6. To reduce vibration and impact loads, the vehicle should run
on a level road with good road conditions whenever possible.
7. During the run-in period, carrying any unnecessary weight
should be avoided. Otherwise, the drive train will wear faster.
8. Try to avoid heavy braking and braking for long periods of
time.
9. Strictly control the running speed of the vehicle.
