EJU31910Filling the fuel tank
CAUTION:

Be careful when refueling. Avoid getting
water and other contaminants in the fuel
tank. Contaminated fuel can cause poor
running and engine damage.
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the hood. (See page 18 for hood
removal and installation procedures.)
(3) Remove the fuel tank filler cap, and then
slowly add the premixed fuel to the fueltank. Stop filling when the fuel level just
reaches the bottom of the filler tube.
(4) Install the fuel tank filler cap and the
hood.
NOTE:

The hood must be removed in order to view
the fuel level in the fuel tank while adding fu-
el.

Be careful not to spill fuel or overfill the fuel
tank.

Do not fill up the filler tube because fuel ex-
pands as it warms up and could overflow.
