2. Inspection and adjustment
(2) Fuel filter element replacement
Replace the fuel filter at specified intervals, before it is
clogged with dust to adversely affect the fuel flow. Also,
replace the fuel filter after the engine has fully been
cooled.
1)Close the fuel cock of the water separator.
2)Remove the fuel filter using a filter wrench (customer
procured). When removing the fuel filter, hold the
bottom of the fuel filter with a piece of rag to prevent
the fuel oil from dropping. If you spill fuel, wipe such
spillage carefully.
3)Clean the filter mounting surface and slightly apply
fuel oil to the gasket of the new fuel filter.
4)Install the new fuel filter manually turning until it
comes into contact with the mounting surface, and
tighten it further to 1/2 of a turn using a filter wrench.

IMPORTANT:
Be sure to use genuine Yanmar part (super fine mesh
filter). Otherwise, it results in engine damage, uneven
engine performance and shorten engine life.
(3) Air cleaner cleaning and element replacement
Replace the air cleaner element periodically even if it is not damaged or dirty.
When replacing the element, clean inside of the dust pan at the time.
If having the air cleaner with double elements, do not remove the inner element. If the engine output is still not
recover (or the dust indicator still actuates if having the air cleaner with a dust indicator) even though the outer
element has replaced with new one, replace the inner element with new one.
