Hydraulic Oil/Temperature Data
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 in the hydraulic oil.
•
Replace hydraulic oil that has been subjected to overheating or damaged components.
•
Change the hydraulic filter as recommended.
•
Keep the hydraulic oil tank filled.
•
Cap and plug all openings after removing components for service or repair.

NOTE:
Selection of the proper hydraulic oil is based on local operating climate and conditions:
•
Use ISO VG 46 antiwear hydraulic oil in general temperate climates.
•
Use ISO VG 32 low-temperature antiwear hydraulic oil (pour point is -43.6°F [-42°C]) in generally
arctic areas where ambient temperatures can reach -22°F (-30°C) during operation.
