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.

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.
