Maintenance and Regular Inspection

Regular

maintenance

Regular

inspection,

adjustment and lubrication are required to keep the
motorcycle in the best safe and efficient condition. The
most important several points about the inspection,
adjustment and lubrication of the motorcycle will be
described in the following pages.

The maintenance intervals shown on the meters

should only be considered as the general guide under
normal driving conditions. However, depending on
climatic conditions, topography, geographical location, and
personal use, the maintenance intervals may need to be
reduced.

Warning

Poor or improper maintenance of a motorcycle will
increase the risk of injury or death during the use of the
vehicle. Maintenance work should be done by Jincheng
dealer or professional maintenance personnel.

Warning

Prior to performing any maintenance operation, check
whether you have the necessary tools, parts, and
technical skills.
- Shut down the engine, and park the motorcycle on a

flat and solid surface.

- Wait for the cooling of the engine, the muffler and

brake disc.

Warning

If you use your vehicle on dusty, muddy or very wet
roads, it is necessary to shorten the maintenance
intervals to clean/replace the air filter element. Please
visit your Jincheng dealer for correct maintenance
intervals.
