The information that is listed is incorrect. Replace the existing information with the following information.

Selecting the Viscosity

The proper oil viscosity grade is determined by the minimum outside temperature. This is the temperature when the machine is started and while the machine is operated. In order to determine the proper oil viscosity grade, refer to the "Min" column in the table. This information reflects the coldest ambient temperature condition for starting a cold machine and for operating a cold machine. Refer to the "Max" column in the table in order to select the oil viscosity grade for operating the machine at the highest temperature that is anticipated. Use the highest oil viscosity that is allowed for the ambient temperature when you start the machine.

Machines that are operated continuously should use oils that have the higher oil viscosity in the final drives and in the differentials. The oils that have the higher oil viscosity will maintain the highest possible oil film thickness. Consult your dealer if additional information is needed.

^( 1 )	First Choice: Oils of full synthetic base stock without viscosity index improvers that meet the performance requirements of the TO-4 specification for the SAE 30 viscosity grade. Typical viscosity grades are SAE 0W20, SAE 0W30, and SAE 5W30. Second Choice: Oils with a TO-4 type additive package and a lubricant viscosity grade of SAE 0W20, SAE 0W30, or of SAE 5W30.
^( 2 )	Except for the hydraulic drive winch gear case. Do not use SAE 50 viscosity grade for the hydraulic drive winch gear case. Instead, use SAE 30 viscosity grade for 0°C (32°F) to 43°C (110°F) or TMS for -10°C (14°F) to 50°C (122°F).
^( 3 )	TMS Transmission Multi-Season (exceeds the TO-4 specification multigrade requirements).
^( 4 )	Commercial Biodegradable Hydraulic Oil (HEES) must meet the AVSpare BF-1 specification.
