GAS

•Fillfuel tank. Use fresh, clean, regular

unleaded gasoline with aminimum of 87

octane. (Use of leaded gasoline wig

increasecarbon and lead oxidedeposits

and reduce valve life). Do not mix oil

with gasoline. Purchase fuel in quanti-

ties that can be used within30 days to

assure fuel freshness.

IMPORTANT: WHEN OPERATING IN

TEMPERATURES BELOW 32°F(0°C), use

fresh, clean winter grade gasoline to help

insure good coldweather starting.

WARNING: Experience indicates that

alcohol blended fuels (caited gasohol or

using ethanol or methanol) can attract

moisture which leadsto separation and

formation of acids dudngstorage. Acidic

gas can damage the fuel system of an

engine while in storage. To avoid engine

problems, the fuel system should be

emptied beforestorage of 30 days or

longer. Drain the gas tank, start the

engine and let it run until the fuel lines and

carburetor are empty. Use fresh fuel next

season. See Storage Instructions for

additional information. Never use engine

or carburetor cleaner productsin the fuel

tank or permanent damage may occur.
