Caution
Contamination can damage internal components and void the manufacturer's warranty. Take
precautions to ensure system cleanliness when removing and reinstalling system lines
1. With the prime mover off, thoroughly clean all dirt and grime from the outside of the motor. Ensure
the surrounding areas are clean and free of contaminants such as dirt and grime.
2. If removing the motor, tag each hydraulic line connected to the motor. If you disconnect hydraulic
lines, plug each open port to keep dirt and contamination out of the motor.
3. Inspect the system for contamination. Look at the hydraulic fluid for signs of system contamination,
such as oil discoloration, foam in the oil, sludge, or small metal particles.
4. Remove the motor as a single unit.

fill with new hydraulic fluid.
