Operation and handling requirements
32
To fill the fuel tank:
(1) Before refueling, stop the engine. Do notstand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity
of sparks, open flames, or other sources
of ignition.
(2) Place the watercraft in a well-ventilated area and in a horizontal position.
(3) Remove the hood, and then ventilate the engine compartment. (See page 26 for
hood removal and installation proce-
dures.)
(4) Loosen the fuel filler cap and remove it.
(5) Slowly add fuel to the fuel tank.
(6) Stop filling when the fuel level just reach- es the bottom of the filler tube. Do not fill
up the filler tube. Because fuel expands when it heats up, heat from the engine or
the sun can cause fuel to spill out of the
fuel tank. Do not leave the watercraft
with a full tank in direct sunlight.
(7) Wipe up any spilled fuel immediately with a dry cloth.
(8) Securely install the hood in its original position, and then install the fuel filler cap
by tightening it until it clicks.
