Bio-Diesel Blended Fuel
Use the following guidelines if bio-diesel blended fuel is used:
• Never use bio-diesel blended fuel containing more than 5% bio-diesel in this vehicle.
• Ensure the fuel tank is as full as possible at all times to prevent moisture from collecting in
the fuel tank.
• Ensure that the fuel tank cap is securely tightened.
• Clean up any spilled fuel immediately to prevent damage to painted surfaces.
• Drain all water from the fuel filter daily before operating the vehicle.
• Do not exceed the engine oil change interval. Extended intervals can result in engine dam-
age.
• Before vehicle storage, drain the fuel tank, refill with 100% petroleum diesel fuel, add fuel
stabilizer and run the engine for at least 30 minutes.
NOTICE: Bio-diesel blended fuel does not have long term stability and should not be stored for more
than three months.
Operating Conditions
NOTICE: Observe the following environmental operating conditions to maintain engine performance
and avoid premature engine wear.
• Avoid operating in the presence of chemical gases or fumes.
• Avoid operating in a corrosive atmosphere such as salt water spray.
• NEVER operate the engine in a floodplain unless proper precautions are taken to avoid
being subject to a flood.
• NEVER expose the engine to the rain.
• The standard range of ambient temperatures for the normal operation of YANMAR
engines is from +5° F (-15° C) to +104° F (+40° C).
• If the ambient temperature exceeds +104° F (+40° C), the engine may overheat and cause
the engine oil to break down.
• If the ambient temperature is between +5° F (-15° C) and -25° F (-32° C), POLARIS rec-
ommends the use of a block heater. See page 35.
