High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See a qualified Sears dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.
Fresh Start® Fuel Cap
The Fresh Start® fuel cap (A) is designed to hold a
cartridge (B) which contains fuel preserver. Adding fuel
preserver helps keep fuel fresh and carburetors clean for
easier starting all season long. The Fresh Start® fuel cap, if
equipped with a cartridge, automatically drips concentrated
fuel preserver into your fuel tank so you don't have to add it
yourself.

NOTICE Fresh Start® fuel preserver cartridge is available as
an optional accessory, retail item 7133386. It is not included

Read and follow all instructions and warnings given in the
Fresh Start® fuel preserver cartridge package.
