SERVICE _NOTES,
#1. Check Aut<. 1 ube tank level before each ride. Top off when oil level shows at the sight glass or before any prolonged use. See
"Lubrication Intervals" for type of oil to use.
#2. Foam elements air filters must be damp with oil at all times to function properly. Remove, clean, and oil filter at least once
per month or every 250
~
500 mile!:; whichever occurs first. (If extremely hard usage, such as dirt riding, clean and lube
daily.) See "Lubrication Intervals" for additional details.
#3. Pre-operational checks should be made each time the machine is used. Such an inspection can be thoroughly accomplished in
a very short time:, and the added safety it assures the rider is more than worth the minimal time involved.
#4. For additional information regarding drive chain, transmission oil level, wet-type air filter, see "Lubrication Intervals'.'.
