2-32 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
If a special lubricant is not available, a heavy oil such as
SAE90 is preferred to a lighter oil because it will stay on
the chain longer and provide better lubrication.
Apply oil to the sides of the rollers so that oil will penetrate
to the rollers and bushings.
Wipe off any excess oil.
