AIR CLEANER ELEMENT
Check the air cleaner element for excessive dirt, dam-
age, or oil. Replace if necessary.
Caution
(Wet type)
Do not clean the air cleaner element with com-
pressed air, replace if necessary.
(Dry type)
When cleaning the air cleaner element, blow
dust off from the inside first, then blow off the
outside.
(General)
1. Loosen the drain plug of the sedimenter and let
the water drain. If necessary loosen the air bleed-
ing plug.
2. Bleed air from the sedimenter.
AIR BLEEDING
From Fuel Tank to Fuel Filter
1. Loosen the air bleeding plug of the fuel filter.
2. Pump the priming pump until no air bubbles flow
from the air bleeding plug hole.
3. Depress the priming pump and tighten the air
bleeding plug.
Note
Open only the air bleeding plug of the filter.
From Fuel Filter to Injection Pump
Pump the priming pump until it becomes hard to
pump.
