Disc Brake Operation Method and Precautions
Operation Method of the Disc Brake:
    • Brake clearance adjustment: Use a 2mm internal hexagonal wrench (between the brake handle and the handlebar tube) to adjust the gap between the brake pad and the brake disc until you have a comfortable hand feeling.
    • Brake pad replacement: Replace the brake pad every six months, if its wear exceeds 1mm, or if the brake pad adjusting screw on the brake handle cannot be adjusted. To replace the brake pad, press one brake pad with a clean slotted screwdriver to empty the space and insert another piece. After replacement, adjust the brake pad adjusting screw on the brake handle to the proper position (where you have a comfortable hand feeling).
    • Running-in period: Allow for a certain time for the running-in of the disc brake surface. After complete running-in, the brake force will noticeably increase. During the first week, avoid forcibly applying the brake to prevent irreversible damage to the brake pad and brake. Instead, slightly engage the brake for normal driving and maintain proper friction between the brake pad and the disc brake disc.
    • Oil change: Use mineral oil for the disc brake. If you feel brake handle fatigue, change the oil (usually every 2~3 years) using an injector suction pipe.
  1. b. Precautions for Disc Brake:

    • Do not apply lubricating oil to the disc brake disc, brake pad, or places near calipers. Avoid touching the disc brake disc and brake pad surface directly with your hand, as it may significantly reduce brake performance.
    • Do not spray water on the new brake to prevent polluting the brake pad with lubricating oil in the assembly gap.
    • The oil pressure disc brake has strong brake force; practice in a safe place to adapt to its differences from common brakes. Avoid forcibly applying the brake to prevent injury due to uncontrolled wheel locking.
Charger Operation Method and Precautions:
  1. a. Operation Method:

    • During charging, insert the battery box plug first, and then insert the commercial electricity AC220V plug. After charging, remove the commercial electricity AC220V plug first, and then remove the battery box plug.
    • The charger indicator lamp will show red during normal charging and green after full charging.
    • If the charging temperature is too high, the red lamp will flash, indicating a temperature protection state. In such a case, move the charger to a cool and ventilated place. Normal charging will resume when the internal temperature reaches 60°C.
    • If no battery is connected during use, the charger output is a pulse voltage smaller than 42V. You can test the actual charging voltage of the charger by applying a 1KΩ resistance load between the positive and negative output terminals.
    • b. Precautions for Charger:

      • Use the charger indoors only.
      • Avoid charging in sealed spaces or under direct sunlight and high-temperature environments. Do not place the charger in the seat cask or trunk while charging.
      • Do not connect the noload charger with AC power supply for an extended period under uncharging conditions.
      • If the indicator lamp is abnormal, emits a smell, or if the charger shell overheats during charging, immediately stop charging and have the charger repaired or replaced.
      • Do not remove or replace any device in the charger without permission.
      • Charge only rechargeable batteries.
      • Avoid using the charger in a combustible gas environment, as it may cause an explosion or fire.
