1. Slowly remove fuel cap to relieve pressure in tank.
2. Slowly add fuel to fuel tank. Do not fill above bottom of
fuel tank neck to allow for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate
before starting engine.
High Altitude
At altitudes over 5,000 ft (1524 m), a minimum 85 octane
fuel 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 an authorized Briggs & Stratton dealer for high altitude
adjustment information. Operation of the engine at altitudes
below 2,500 ft (762 m) with the high altitude kit is not
recommended.
Transporting
Do not tip engine or equipment at an angle which causes
fuel to spill.
