appropriately sized dispensing spout.
• NO Smoking!
• NO Sparks!
• NO Flames!
• Allow engine to cool before filling fuel
tank.

bottom of filler neck to allow for fuel
expansion.
IMPORTANT: Refer to Engine Manual for
proper fuel type and tank capacity.
Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner. Always
place containers on the ground away from
your vehicle before filling.
When practical, remove gas-powered
equipment from the truck or trailer and refuel
it on the ground. If this is not possible, then
refuel such equipment on a trailer with a
portable container, rather than from a
gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete. Do not use a nozzle lockopen device.
Check fuel supply before starting engine.
DO NOT fill gasoline tank indoors, when
engine is running, or while engine is hot.
Allow engine to cool several minutes before

Replace gasoline tank cap securely and
clean any spilled fuel before starting engine.
If fuel is spilled on clothing, change clothing
immediately.
NEVER store fuel inside where there is an
open flame, such as a water heater.
ALWAYS drain fuel outdoors away from
ignition sources.
ALWAYS shut off engine, and remove key,
and close fuel shutoff valve when transporting
