Periodic Maintenance Procedures
Replace Fuel Filter
A
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.
TNV DI Service Manual
• ALWAYS be environmentally
responsible.
• Follow the guidelines of the EPA or
other governmental agencies 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.
• Failure to follow these procedures may
seriously harm the environment.
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.

turning it to the left (Figure 5-14, (1)). When
removing the fuel filter, carefully hold it to
prevent the fuel from spilling. Wipe up all spilled
fuel.
