Cleaning
If the chain is not too dirty, the operation of lubrication is normally
sufficient to clean the chain.
When the accumulation of dirt on the chain (sand, mud, asphalt particles
or other foreign materials) is excessive, the chain must be washed with a
brush and kerosene. After washing, the chain has to be dried immediately with
a jet of compressed air.
After off-road use, when the dirt built-up is heavy, wash the chain with
a water jet, then dry it immediately with compressed air.

WARNING
• Avoid the use of steam, gasoline or solvents.
When cleaning O-Ring chains, avoid the use of hard brushes or other methods that could damage the rubber O-Rings (compressed air should be kept at 50 cm/2 ft distance minimum).
• After washing, immediately lubricate the chain as explained in the next chapter.

Lubrication
To obtain good performance and long life, chain must always be lubricated when
in service.
All well lubricated chains keeps the friction between the working surfaces
to a minimum by creating a protective surface between the sliding surfaces
of the pin and bushing and also between the bushing and roller. A lack of lubrication
increases friction between these surfaces, resulting in an increase in friction
resulting in a higher absorption of power, therefore an increase in the working
temperature of the components. This higher than normal temperature will result
in the lubricant burning and becoming less effective, therefore increasing
chain wear.
Signs of poor lubrication are rapid elongation of the chain, rust (reddish
areas on the chain surfaces), and squeaks when operating.
In the O-Ring chains, lubrication is provided by grease sealed in the working
area by O-Rings.However, it is still necessary to provide periodic lubrication
to the chain. Lubricant between roller and bushings will decrease friction
and heat, and will improve the efficiency of the drive, extending chain
and sprockets life.
Lubrication also keeps O-Rings in good condition and protects
the metallic components from rust and corrosion.
