Fuel
•
Use #2 diesel fuel or a mixture of #2 diesel and #1 diesel fuels in cold weather climates.
•
Use only ultra-low sulfur fuel, with a limit of S
<
15 mg/kg for all normal operations.
•
SANY does not recommend the use of any diesel fuel with a cetane level less than 40.
•
Do not use gasoline, kerosene, or any unapproved fuels in the fuel system.
•
If fuel waxing or bacterial growth should occur in the fuel system, contact a SANY dealer.
•
Make sure there is no water or foreign material in the fuel. Take appropriate precautions to prevent fuel
contamination during refueling.
Engine Coolant
Engine coolant is an important fluid protecting against both engine coolant boiling and freezing. Anti-freezing
engine coolant is also necessary in regions where freezing protection is unnecessary.
•
If using concentrated engine coolant, use distilled water to dilute per instructions on engine coolant container.
Natural water, such as river water and well water (hard water) contain large amounts of minerals (calcium,
magnesium, etc.) which can form scale in the engine and radiator. Mineral scale is not easily removed and can
cause overheating.
•
Precautions in this manual must be followed when working with engine coolants.
•
Some engine coolants are flammable. Keep them away from open fire.
•
If the engine is overheating, wait for the engine to cool down before refilling engine coolant.
WARNING!
• Fuel or fuel vapors that come into contact with hot surfaces or electrical components can
cause a fire.
• Never service the fuel system near an open flame or while smoking.
• Clean up spilled fuel immediately.
Failure to follow these warnings could result in death or serious injury.
NOTICE!
Never dilute fuels. Damage to the injection system can result, which causes the machine to
operate improperly.
