Fuel Recommendations

Explosive Fuel can cause fires
and severe burns.
Do not fill fuel tank while engine
is hot or running.
Gasoline is extremely flammable and
its vapors can explode if ignited. Store
gasoline only in approved containers, in
well ventilated, unoccupied buildings, away
from sparks or flames. Spilled fuel could
ignite if it comes in contact with hot parts or
sparks from ignition. Never use gasoline as a
cleaning agent.
NOTE: E15, E20 and E85 are NOT approved
and should NOT be used; effects of
old, stale or contaminated fuel are not
warrantable.
