Lubricating the chain
Lubricate the chain, following these instructions:
WARNING * : Never use grease to lubricate the chain. Grease helps to accumulate dust
and mud, which act as abrasive and hepl to rapidly wear out the chain, the sprocket,
and the crown.
Disassembling and cleaning
When particularly dirty, remove and clean the chain before lubrication.
Work as follows:
Set a stand or a block under the engine and see that the rear wheel is lifted from the
ground.
1 -Remove the sprocket guard (3), the spring (1), the joint (2) and the chain.
2 - Check that the chain is neither worn out nor damaged. If the rollers or the links are
damaged, replace the chain by following 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 tricloroetilene, clean and
lubricate the chain to prevent oxidation.
WASHING THE CHAIN WITH OR
Wash using oil, diesel oil, or paraffin oil. Never use gasoline, tricloroetilene, or solvents,
as the OR may suffer damages. Use instead special sprays for chains with OR.
LUBRICATING THE CHAIN WITHOUT OR
First dry, then plunge the chain in a bisulphide molybdenum lubricant, or in high visco-
sity engine oil. Warm up the oil before use.
