Care & Maintenance Notes

• Lubricate the chain using approved chain lube every 500 km for seal ring chains or 1000 km for standard chains.
• Clean the chain every 2500–3000 km, then re-lubricate.
• Use a nylon brush or soft cloth; avoid steel wire brushes.
• Do not use petrol, thinner, hot water, or high-pressure water jets directly on seal ring chains.
• Maintain proper chain slack of at least 1 inch.
• Replacing dampers along with the chain kit is recommended for extended service life.
