Recommended Lubricants, Fuel,
and Engine Coolant
NOTICE!
Never mix lubricants of different types or
viscosities (weights), and never overfill the
system that is being serviced. Failure to follow
these standards can damage the machine or
cause improper machine operation.
Always use SANY-approved lubricants, engine coolants,
and filters. SANY is not responsible for damage caused
by using unauthorized lubricants and engine coolants.
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 after removing
components for service or repair.
Lubrication and Grease
Always use clean extreme pressure (EP) grease when
greasing the machine. Avoid using low-viscosity greases.
SANY recommends EP 2 or equivalent grease designed
for:
• Heavy-duty bearings and general industrial lubrication.
• Heavy-duty plain and rolling element bearings
operating under severe conditions, including shock
loading in wet environments.
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.
Fuel
• 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.
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.
