SAFETY
For maximum engine life, YAN MAR 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.
Never use an engine starting aid such as ether.
Engine damage will result.
• Always be environmentally
ffi
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.
Never engage the starter motor while the engine is
running. This may damage the starter motor pinion
and/or ring gear.

Safety Precautions
New engine break-in:
• On the initial engine start-up, allow the engine to
idle for approximately 15 minutes while you check
for proper engine oil pressure, diesel fuel leaks,
engine oil leaks, coolant leaks, and for proper
operation of the indicators and/or gauges.
• During the first hour of operation, vary the engine
speed and the load on the engine. Short periods
of maximum engine speed and load are
desirable. Avoid prolonged operation at minimum
or maximum engine speeds and loads for the
next four to five hours.
• During the break-in period, carefully observe the
engine oil pressure and engine temperature.
• During the break-in period, check the engine oil
and coolant levels frequently.
• Never attempt to modify the engine's design or
safety features such as defeating the engine
speed limit control or the fuel injection quantity
control.
• Failure to comply may impair the engine's safety
and performance characteristics and shorten the
engine's life. Any alterations to this engine may
affect the warranty coverage of your engine.
YANMAR Limited Warranty on page 2-3.
Protect the air cleaner and electric components
from damage when you use steam or high-
pressure water to clean the engine.
Never use high-pressure water or compressed air
at greater than 28 psi (193 kPa; 19686 mmAq) or a
wire brush to clean the radiator fins. Radiator fins
damage easily.
