Fuel
Observe the following when adding fuel:
•
Use #2 diesel fuel. Use 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 recommends using diesel fuel with a cetane level greater than 40.
•
Do not use gasoline, kerosene, or any unapproved fuels in the fuel system.
•
If fuel waxing or bacterial growth occurs in the fuel system, contact a SANY dealer.
•
Make sure that 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 that prevents engine overheating and freezing.
•
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), contains large amount 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 before refilling the 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, causing the machine to operate
improperly.
