Fluid Capacities
NOTE: The following listed capacities are approximate only. For exact capacities, use the inspection points,
inspection plugs, dipsticks, and sight glasses.
• When operating the machine in temperatures below 32°F (0°C), use SAE 10W, SAE 10W-30, or SAE 15W-40
engine oil.
• Sulfur oxide is a by-product of diesel fuel combustion. When sulfur oxide combines with water, sulphuric acid
is created. Always use ultra-low-sulfur diesel (ULSD) that contains less than 0.2% sulfur to avoid potential
engine damage from sulfur oxide.
• If low-quality fuels are used, the oil change interval must be decreased due to shortened engine oil life.
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.
