• Installation must be carried out in accordance with the
circuit or piping diagram.
• Always cover or cap all motor case drain and high pres-

replacement motor.
• Always ensure that all connections to the motor or re-
placement motor are capped or covered during the initial
installation.
• Connect and tighten each hydraulic line one at a time
removing caps or covers just before each connection is
made.
• Additional care must be taken to vent entrapped air from
the motor rear head. If mounted as shown below, connect
the "vent line" to the reservoir. Please note that all PRO-
