Lubrication and Cleaning:
Lubricate every 500 km (300 miles) or sooner
if chain appears dry.
The O-rings in this chain can be damaged by
steam cleaning, high pressure washers, and
certain solvents. Clean the side surfaces of
the chain with a dry cloth. Do not brush the
rubber O-rings. Brushing will damage them.
Wipe dry and lubricate only with SAE 80 or
90 gear oil. Commercial chain lubricants may
contain solvents which could damage the
rubber O-rings.
