Use this table to calculate the cooling load.
Hydraulic fluid
High altitude or ambient conditions can have an effect on the temperature of hydraulic fluid. Fluid
that is too cool is thick, which causes increased friction and poor lubrication. Fluid that is too hot is
thin, which can accelerate wear on the parts, increase the formation of sludge, degrade the fluid,
and decrease its lubrication and protective qualities.
Compressed air
Compressed air operates the bleed-down valve.
If the available air pressure is too high, install an air regulator (not included) to reduce the pressure.

Hypertherm does not always ship the pump with hydraulic fluid in the tank.
Domestic pumps usually ship from the factory with AW 32 hydraulic fluid.
Type
Antiwear (AW) mineral oil or synthetic hydraulic fluid, ISO viscosity grade (VG)
32 or 46.
Hydraulic fluid tank capacity
151 L (40 gallons).
If the pump is air cooled, increase the hydraulic fluid volume to fill the hoses and
the heat exchanger.
Minimum Maximum
Pressure 5.2 bar (75 psi). 8.3 bar (120 psi).
