RECOMMENDED LUBRICANTS, FUELS, AND COOLANT
Always use SANY approved lubricants, coolants, and filters. SANY is not responsible for damage caused by using
unauthorized lubricants and 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.
NOTICE!
Never mix lubricants of different types or viscosities (weight) and never overfill the system
that is being serviced.
Failure to follow this notice could damage the machine or cause it to operate improperly.
