2.4.1 Hydraulic power unit and hydraulic motors
CAUTION
Operating the hydraulic power unit (HPU) for extended periods of time
without connecting the hydraulic motor will overheat the system and
may damage the pump.
The high-torque, low-speed hydraulic motor mounts directly to the RDU. To
reverse the bar rotation direction, switch the hydraulic hoses at the motor or at the
HPU.
Table 2-5 on page 18 shows the available HPUs and their specifications.
