AIR BLEEDING

1. AIR BLEEDING
(1) Remove the vent cap from the top of the cover by turning the vent cap
counterclockwise. Fill the cover full of clean fuel. Reinstall the cap and
tighten.
(2) Start the engine. When the lubrication system reaches its normal
operating pressure, increase engine speed to high for 2 to 3 minutes.
(3) After the air is purged, and the engine is running, loosen the vent cap.
When the fuel level fills to following position, quickly tighten the vent
cap. Tighten the vent cap until the vent cap run idle with click sounds.
Fuel level:
12.7-38 mm {0.5-1.5 in.} Above top of collar.
NOTICE
• Thoroughly wipe off any spilled fuel.
• Start the engine and check the fuel system for leaks.
! WARNING
• Always drain the fuel into a container and dispose of it properly.
Be careful not to spill any of the fuel.
• If fuel is spilled on engine parts, wipe it off entirely. It is danger-
ous since it can cause a fire which can result in serious personal
injury or death.
•
Do not smoke when performing maintenance on the fuel system.
•
Keep flame and heat away from the fuel system since the fuel is
flammable and can cause a fire resulting in serious personal
injury or death.
• Any of these can result in personal injury and/or property dam-
age due to fire.
• Use the designated special tool and fuel filter wrench to tighten
the fuel filter. Use of an ordinary tool (for example, chain-type
tool) can scratch or dent the peripheral surface of the fuel filter. If
the fuel filter is damaged, it can cause fuel to leak, thus resulting
in a fire or other serious accidents and can result in serious per-
sonal injury or death.
•
After replacing the filter, inspect the external surface of the fuel
filter for checking scratches and dents. It is dangerous to use a
scratched or dented fuel filter, since it can cause fuel to leak and
lead to a fire or other serious accidents and can result in serious
personal injury or death.
• After replacement of the element, operate the engine for trial to
check to see if there is any fuel leakage around the fuel filter.
Fuel leakage can cause a fire and can result in serious personal
injury or death.
