Periodic Maintenance Procedures

Perform the following maintenance every 500 hours
of operation.

• Replace Air Cleaner Element

• Replace Fuel Filter

• Clean Fuel Filter / Water Separator

Replace Air Cleaner Element

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

Every 500 Hours of Operation

CAUTION

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.

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.

CAUTION

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.
