Please maintain the degree of contamination 

within NAS 1 638-Grade 12.  Use 25 μm or finer line filter.

Use fluids equivalent to ISO VG 32 or VG 46. 

Use hydraulic fluids which satisfy the recommended

Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU). 

Oil temperatures between -15/+70°C (5 - 158°F).  

When phosphate ester fluid is used,  prefix "F-" to the model
