IMPORTANT: Using stale, contaminated or improper fuel can result
in engine and fuel system damage. Repairs caused by stale,
contaminated or improper fuel are not covered by warranty.
contaminated or improper fuel are not covered by warranty.
Use regular grade unleaded fuel with an octane rating of 87 octane or
higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE
reformulated fuel are acceptable. Do not use fuel or additives containing
methanol as engine damage can occur.

methanol as engine damage can occur.
Always use fresh, clean fuel that is purchased in a quantity that can be
used within approximately 30 days. Fuel stabilizer should always be
added to the fuel each time fuel is purchased. Add stabilizer before filling
the fuel container to insure proper mixing. Such practice helps prevent
engine performance problems and allows fuel storage in the machine all
year without draining.

Store fuel in plastic containers to reduce condensation. Make sure the
cap on the fuel container is tight to reduce fuel contamination and
evaporation. For best fuel storage life, use a self-sealing gas can.

Fuel is blended to give best seasonal performance. To avoid engine
performance problems such as hard starting or vapor lock, use in-season
fuel. Use fuel during warm weather that was purchased during that
season, and use fuel during cold weather that was purchased during that
season.

Fuel can become stale in machines with engines that are used
