FUEL MIXTURE e Your toot is powered by a two-cycle engine which requires a fuel mixture of regular unleaded gasoline and a high quality engine oil specially made for 2-cycte, air cooled engines. The internal design of the 2-cycle engine requires lubricationof moving parts. Lubricationis provided whenthe recommended mixture of gasolineand oil is used. • Gasoline must be clean and fresh. After a short periodoftime, gasoline willchemically break down and form compounds that cause hard startingand damage in 2-cycleengines. 4. DO NOT USE: • BIA OIL (Boating Institute of America) --- Does not have proper additives for air-cooled, 2-cycleengines and can cause enginedamage. • AUTOMOTIVE OILDoes not have proper additives for 2-cycle engines and can cause damage. 5. HOW TO MIX FUEL AND FILL TANK a. Pour l/2ofthe regular unleadedgasolineto be used into an approved, marked container. Do not mix gasoline and oil directly in the fuel tank. b. Add entire measure of engine oil. c. Cover container tightly and shake for one minute. • The correct measure of gasoline to oil is very important. Too much oil in the mixture willfoul the spark plug. d. Slowly remove fuel container cover. e. Add remainder of gasoline. f. Cover container tightly and shake again. ICAUTION:I TOOlittle oil will cause the engine to overheat and seize, h. Slowlyremove thefuel cap.Refer to"Specifications" for fuel cap location. • Always mix the fuel thoroughly in a container sincegasolineand oildo not readilycombine.Donot mix gasoline and oildirectly in the fuel tank. i. Fill the tank using a spoutor funnel. j. Reinstallthe fuel cap securely. , , 5 i ii i iiiiii B. PRE-OPERATION iiii1!11111111 CHECKS 3. CHECK THE UNIT FOR LOOSE BOLTS, NUTS, OR FITTINGS.
