CHANGE THE FUEL FILTER
Figure 9
To avoid the risk of burns, only proceed once the engine is stationary and has been allowed to cool. Only
use original Yanmar filters.
• Remove the filter (1) by unscrewing it.
• Moisten the sealing gasket of the new filter with diesel or engine oil.
• Manually tighten the new filter on the support until it comes into contact with the gasket, then tighten by
3/4 of a turn.
• Loosen the Bleed Screw on the filter mount and pump the pre-filter hand pump until the fuel comes out
with no air bubbles present.
• Tighten the Bleed Screw and start the engine while pumping the hand pump during the first stages of
start-up.
General directions
Do not fill the new fuel filter until it has been
installed on the support, to prevent any damaging
impurities from entering the fuel circuit and injection
system.
NOTICE
Failure to comply completely or partially with these
requirements may result in the risk of serious
damage to the engine and may even, on occasion,
invalidate the warranty.
