Fuel
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.
Observe the following when adding fuel:
• Use #2 diesel fuel. In cold weather climates, use a
mixture of #2 diesel and #1 diesel fuels.
• 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 occurs 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.
Windshield Washer Fluid
Only use clean automotive windshield washer fluid. Do
not mix concentrates into the washer fluid. In cold
weather areas, use washer fluid with a low-temperature
rating.
Hydraulic Oil Description
Hydraulic oil is an important part of the hydraulic system.
Hydraulic oil lubricates hydraulic system components,
carries heat away from components, and contains
anti-corrosion additives and detergents.
Hydraulic system malfunctions are often caused by poor
machine maintenance practices. Following the guidelines
below will result in proper hydraulic system maintenance:
• Do not use any additives with the hydraulic oil.
• Replace hydraulic oil that has been subjected to
overheating or damaged components.
• Change the hydraulic filter as recommended.
• Keep the tank filled to the full level of hydraulic oil.
• Keep the oil cooler free of dust and debris.
• Cap and plug all openings when removing
components for service or repair.
NOTICE!
Failure to inspect hydraulic oil for contamination
may damage the hydraulic system or cause the
machine to operate improperly.
