Cleaning and Lubricating
After inspecting the slack, clean the chain and
sprockets while rotating the rear wheel. Use a
dry cloth with chain cleaner designed specially
for O-ring chains, or neutral detergent. Use a
soft brush if the chain is dirty.
After cleaning, wipe dry and lubricate with the
recommended lubricant.
Recommended lubricant:
Drive chain lubricant designed
specifically for O-ring chains.
If not available, use SAE 80 or 90 gear
oil.

Do not use a steam cleaner, a high pressure
cleaner, a wire brush, volatile solvent such as
petrol and benzene, abrasive cleaner, chain
cleaner or lubricant NOT designed specially for
O-ring chains as these can damage the rubber
O-ring seals.
Avoid getting lubricant on the brakes or tyres.
Avoid applying excess chain lubricant to prevent
spray onto your clothes and the vehicle.
