Replace Fuel Filter
Replace the fuel filter at specified
intervals to prevent contaminants from
adversely affecting the diesel fuel flow.
1. Stop the engine and allow it to cool.
2. Close the fuel cock of the fuel filter / water
separator.
3. Turn the retaining ring (Figure 14, (1)) to the
left (Figure 14, (5)) .
4. Carefully remove the cup (Figure 14, (3)).
Pour the fuel into an approved container and
dispose properly. Hold the bottom of the cup
with a shop towel to prevent the fuel from
dripping. Wipe up any spills immediately.

A
DANGER
0000009en
FIRE AND EXPLOSION HAZARD!
• Diesel fuel is extremely 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 extremely
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
0000008en
For maximum engine life, Yanmar
recommends that when shutting the
engine down, you allow the engine to
idle, without load, for 5 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.
CAUTION
0000013en
Be responsible to the environment.
Follow these procedures for hazardous
waste disposal. Failure to follow these
procedures may seriously harm the
environment.
• Follow the guidelines of the EPA or
other governmental agency for the
proper disposal of hazardous
materials such as engine oil, diesel
fuel and engine coolant. Consult the
local authorities or reclamation facility.
• NEVER dispose of hazardous
materials irresponsibly by dumping
them into a sewer, on the ground or
into ground water or waterways.
