2 - Check that the chain is neither worn out nor damaged. If the
rollers or the links are damaged, replace the chain by fol-
lowing the instructions given in the Periodical Maintenance
Table.
3 - Check that neither the sprocket nor the crown are damaged.
4 - Wash and clean the chain as described hereunder.
Washing the chain without OR
Wash using either oil or diesel oil. When using gasoline or tri-
cloroetilene, clean and lubricate the chain to prevent oxidation.
Lubricating the chain without OR
First dry, then plunge the chain in a bisulphide molybdenum
lubricant, or in high viscosity engine oil. Warm up the oil before
use.
Note * : As an alternative, you can use suitable spray lubri-
cants.
5 - If the chain has been cut, reassemble using a joint.
6 - Assemble the joint spring (a) by turning the closed side to the
chain direction of rotation as shown in figure below.
NOTE*: Even if all the joints are reusable when in good con-
ditions, for safety purposes we advise using new joints when
reassembling the chain.
7 - Accurately adjust the chain as described in the paragraph
"Chain adjustment".
WARNING: The chain oil has NEVER to get in
contact with the tires or the rear brake disk.
