NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
Add Fuel Stabilizer to
Extend Fuel Storage Life
IMPORTANT: Fuel stabilizer is recommended
for extended storage (see Fuel System on
page 32).
Add Fuel to Fuel Tank
1. ALWAYS place unit in open or well-
ventilated area.
2. Stop engine and allow to cool.
3. Clean Fuel Cap and surrounding area to
prevent dirt from entering Fuel Tank.
4. Remove fuel cap.
IMPORTANT: Refer to Engine Manual for
correct type and grade of fuel.
5. Fill fuel tank to the bottom of filler neck.
See SPECIFICATIONS on page 35 for
fuel tank capacity.
IMPORTANT: DO NOT OVERFILL! This
equipment and/or its engine may include
evaporative emissions control system
components, required to meet EPA and/or
CARB regulations, that will only function
properly when the fuel tank has been filled to
the recommended level. Overfilling may
cause permanent damage to evaporative
emissions control system components. Filling
to the recommended level ensures a vapor
gap required to allow for fuel expansion. Pay
close attention while filling the fuel tank to
ensure that the recommended fuel level
inside the tank is not exceeded. Use a
portable gasoline container with an
appropriately sized dispensing spout when
filling the tank. Do not use a funnel or other
device that obstructs the view of the tank
filling process.
6. Replace fuel cap and tighten.
7. ALWAYS clean up spilled fuel.
Fuel Shut-Off Valve
IMPORTANT: The fuel shut-off valve MUST
be in the closed position prior to transporting
the unit.
