Your new rider will give excellent service for many
years if given reasonable care and maintenance,
as follows:
1. Check the oil level in the crankcase
frequently, at least every 5 hours of operation.
When checking oil level be sure the area
around the oil fill cap is cleaned of all debris
before it is removed. Otherwise debris can fall
into the crankcase and cause damage.
