Since this hydraulic unit is provided with two return ports (inside oil), two drain ports (upper oil surface) and
one discharge port, piping them if necessary.
All the piping port is capped with taper cap (vinyl cap).
Bind the piping with seal tape.

Caution
・
If it operates without putting oil in the tank, burnt and abrasion occur in the pump body, and it may be
damaged.
・
Since oil is supplied to the hydraulic circuit on the machine at the initial operation of the machine, be
careful of the oil decrease inside the tank.
・
The oil level inside the tank will vary a lot with the different hydraulic circuit on the machine, be careful
that if the oil is overflowed from the tank or the oil level is lower than its usual level.
