（1）. The lubrication of the clutch cable should be regularly coated with grease on the hook and connection parts of the clutch cable.
（2）. Clutch pedal stroke: The free stroke of the clutch pedal is 20-30mm, with a clearance of 3-4mm between the release bearing and the release finger. There are two adjustments for free travel: one is the adjustment nut at the connection between the cable and the separation fork shaft. Right turn nut reduces free travel; Left turn nut increases free travel. The other part is the adjustment spring on the pedal and connecting line.
Regular maintenance of transmission
（1）. If there is a phenomenon of not being able to shift gears or shifting gears properly during operation, the length of the flexible shaft should be adjusted to ensure that all gears are in the correct position. Before adjustment, it should be determined whether the length of the flexible shaft has free travel, and any missing bushings must be replaced.
（2）. When adjusting, place the transmission control lever in neutral position, loosen the locking nut of the transmission end flexible shaft joint, and adjust the length. Simultaneously, ensure that the gear selector arm of the transmission is in the ideal middle position.
（3）. Regularly check the height of the transmission lubricating oil, and if it is found to be below the specified oil level, it should be replenished in a timely manner.
Lubricating oil must be replaced every six months.
