running, since spilled fuel could ignite if it comes in contact
with hot parts or sparks from ignition. Do not start the
engine near spilled fuel. Never use gasoline as a cleaning
agent.
General Recommendations
Purchase gasoline in small quantities and store
in clean, approved containers. A container with a
ŒŠ™ŠŒ’¢1˜1X1Š••˜—œ1˜›1•Žœœ1 ’‘1Š1™˜ž›’—1œ™˜ž1’œ1
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.

Unleaded gasoline is recommended, as it leaves less
combustion chamber deposits. Leaded gasoline may
be used in areas where unleaded is not available
and exhaust emissions are not regulated. Be aware
however, using unleaded gasoline will require more
frequent cylinder head servicing.
