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, therefore, form
the habit of periodically servicing the chain. This
service is especially necessary when riding in
dusty conditions.
1. Use any brands of spray type chain lubricant.
First,. remove all dirt and mud from the chain
with a brush or cloth, then spray a lubricant
between both rows of side plates and on all
center rollers.
2. To clean the chain, remove the chain from the
machine, dip it in solvent, and clean out as
much dirt as possible. Take the chain out of
the solvent and dry it. Immediately lubricate
3-22 the chain to prevent rust.
