Replace Air Cleaner Element
NOTICE
The maximum air intake restriction, in terms of
differential pressure measurement, must not
exceed 0.90 psi (6.23 kPa; 635 mmAq). Clean or
replace the air cleaner element if the air intake
restriction exceeds the above mentioned value.
Replace the air cleaner element
(Figure 5-12, (2))
every 500 hours even if it is not damaged or dirty.
When replacing the element, clean the inside of the
air cleaner case
(Figure 5-12, (4))
.
If the air cleaner is equipped with a double element,
only remove and replace the inner element
(Figure 5-13, (1))
if the engine lacks power or the
dust indicator actuates (if equipped). This is in
addition to replacing the outer element.
Replace Fuel Filter
DANGER
FIRE AND EXPLOSION HAZARD!
• Diesel fuel is flammable and
explosive under certain
conditions.
• When you remove any fuel system component
to perform maintenance (such as changing
the fuel filter) place an approved container
under the opening to catch the fuel.
• NEVER use a shop rag to catch the fuel.
Vapors from the rag are flammable and
explosive.
• Wipe up any spills immediately.
• Wear eye protection. The fuel system is under
pressure and fuel could spray out when you
remove any fuel system component.
• Failure to comply will result in death or
serious injury.
NOTICE
For maximum engine life, Yanmar recommends that
when shutting the engine down, you allow the
engine to idle, without load, for five minutes. This
will allow the engine components that operate at
high temperatures, such as the turbocharger (if
equipped) and exhaust system, to cool slightly
before the engine itself is shut down.
