4. USE HYDRAULIC FLUIDS THAT COMPLY WITH HTMA SPECIFICATION 5.7, THE HYDRAULIC FLUID
SHOULD HAVE A VISCOSITY BETWEEN 100 AND 400 SSU (20-82 CENTISTOKES) AT THE MAXI-
MUM AND MINIMUM EXPECTED OPERATING TEMPERATURES. PETROLEUM BASED HYDRAULIC
FLUIDS WITH ANTI-WEAR PROPERTIES AND A VISCOSITY INDEX OF 140 WORK FOR A WIDE
RANGE OF OPERATING CONDITIONS.
THE FOLLOWING OILS MEET HTMA SPECIFICATION 5.7:
AMOCO RYKON MV
CITGO A/W ALL TEMP
SUNVIS 706
MOBIL D.T.E. 13
