It wasn't your exact model, but it looks to me like they want 10w40. I'll try to make a shortcut to the manual. The hyd oil was on page 115. LOL I would use 10w40. Hydraulic Fluid Keep the hydraulic system filled with one of the following: • 10W40 SE or SF manufacturers suggested oil. • Hydraulic fluid as recommended by equipment manufacturer, but the viscosity should not drop below 50 SSU or contain less than .125% zinc anti-wear additives. CAUTION: Do not mix oil types. Any mixture, or an unapproved oil, could deteriorate the seals; Maintain the proper fluid level in the reservoir. When changing fluid, completely drain old oil from the system. It is suggested also that you flush the system with clean oil. Filtratio n· Recommended filtration 20-50 micron. Oil Temperature Maximum operating temperature 200 OF 193.3°el. ( ( service manual [Reply]   [No Email]

That's why the SE & SF classifications are obsolete. So....you're best bet may be hyd fluid if it still has zinc.   [Reply]  [No Email]

Use a brand name oil, either valvoline or shell, what ever I find on sale. I would stay away from additives. The owners manual is concerned with hydraulic oil damaging the seals. 10 w 40 means the oil is 10 weight in the winter. 15 w 40 means it 15 w in the winter. Wouldn't use in Indiana.
