Hydraulic Fluid

This machine is supplied with Phillips 66 Powerflow NZ Hydraulic Fluid.

Do not substitute! Though Phillips 66 Powerflow NZ Hydraulic Oil is compatible

with most oils containing Zinc, mixing will result in poor machine performance,

could damage hydraulic components, and will lessen the environmental benefits

gained by using Phillips Powerflow NZ Hydraulic Oil.
