HYDRAULIC SYSTEM MAINTENANCE

The

REED 00 MODEL C50SS

utilizes a diesel engine as the main source of power, which

drives the main hydraulic pump. The hydraulic pump is used to supply the flow and
develop the necessary pressure to operate the concrete pump. As with any operational
system, it is only as good as it is maintained. The hydraulic system is a critical system and
it is for this reason that it is

IMPORTANT

that it receive extra care and good maintenance.

This section is offered to alert you and guide you in maintaining the hydraulic system.

CONTAMINATION is the downfall of most hydraulic
systems and a major contributor leading to system
malfunctions. Extreme care must be exercised to
prevent dirt from entering the system. Make it a habit
to ALWAYS cap or plug open ports and hydraulic
lines.
