Maintenance Cautions and Warnings
When you maintain or repair the motorcycle, please use original components and parts, accessories,
lubricating oil and other materials that are made or recognized by CSC Motorcycles. Caution! If you use
any parts or components other than those recommended by CSC, it may adversely affect the
performance, reliability, stability, or warranty of your motorcycle.
When working on your motorcycle, you should follow this guidance:
 Warning! Whenever the motorcycle is to be reassembled after disassembly, washers, seals, and
cotter pins need to be replaced.
 When you fasten a series of bolts or nuts, you should do so in a diagonal pattern.
 Warning! Do not use flammable cleaning fluid to clean components and parts.
 Caution! Before assembly operations, add lubricating oil or lubricating grease to lubricated
surfaces.
 Warning! After assembly, make sure all parts are properly assembled and tightened.
 Warning! Stop the engine when repairing the motorcycle.
 Warning! If the maintenance operation needs to be done while the engine is working, make
sure the area is well-ventilated.
 Warning! Gas is flammable and combustible, so do not smoke or provide ignition sources in the
work area.
 Warning! The battery can liberate hydrogen, which is flammable. Do not smoke, ignite or make
sparks near the battery, especially when it is charging.
 Warning! The electrolyte of the battery contains sulfuric acid. If your eyes, skin or clothes are
splashed with electrolyte, rinse them thoroughly with water and seek immediate medical
attention.
 Warning! Disconnect the negative battery terminal when performing any maintenance on the
motorcycle engine, drive train, or fuel system.
Component Cleaning
After parts are disassembled, they may need to be cleaned. Cleaning methods vary according to the
characteristics of the parts.
 To remove oil or grease contamination, CSC recommends using Simple Green or other similar
degreasing agents.
 Warning! Never use gasoline as a cleaning agent.
 To remove carbon deposits, use mechanical or chemical methods. The mechanical method uses
a wooden or plastic scraper or blade to clear the carbon deposit first, and then rinse the parts
with an appropriate cleaning agent. The chemical method is to soak the parts in the cleaning
agent first, then clean them with a brush, and then rinse them with hot water.
