Drive chain lubrication
The chain consists of many parts which work
against each other. If the chain is not
maintained properly, it will wear out rapidly.
Without lubrication the chain could wear out
within 1,500 km (1,000 mi); therefore, form
the habit of periodically servicing the chain.
This service is especially necessary when
riding in wet or dusty conditions.
1. Use any of the many brands of spray
type chain lubricant. First, remove dirt
and mud from the chain with a brush or
cloth and then spray the lubricant
between both rows of side plates and on
all center rollers. This should be per-
formed every 500 km (300 mi).
