TO ENSURE SAFETY
• If the chain keeps coming off the sprockets during use, replace the sprockets and the chain.
• If using a chain tensioner, use the special CS-S500 18T or 20T sprocket with chain guard. Do not use any other types of sprockets, otherwise the chain
may come off the sprockets.
< SG-S7001-11 >
• When you perform oil maintenance, use the SG-S700 OIL or TL-S703 maintenance kit.
When you replace the oil, follow the manual for TL-S703. When you replace the seal on the right side, use TL-S704.
If SG-S700 OIL is not used, problems such as an oil leakage and gear shifting malfunction may occur.
< CT-S500 / CT-S510 >
• Clean the chain tensioner periodically and lubricate all moving parts and pulleys.
• If there is a large amount of play in the pulleys and an abnormal amount of noise is generated while riding, replace the pulleys.
• Do not disassemble the pulley unit.
• If the tension applied is too strong, noise may be generated while riding.
• If the chain becomes elongated and excessive looseness occurs, readjust the chain tension.
