HYDRAULIC PIPING
7.1
Piping
Motor pump type (EHU15/30R**00*-03)
There are different port types below for motor pump type. Be sure to connect piping at the all ports. Details
on the piping positions can be found in the outside view drawing. Use hoses for the piping work, and fasten
them with sealing tape.
In addition, the motor pump type is not equipped with an oil cooler. Use the cooling equipment separately
so that they can be used at an appropriate oil temperature.
