Maintenance
Hydraulic System
Absolute cleanliness of the hydraulic system is
a must. The smallest amount of foreign
material in the system can cause extensive
damage to the pump, motor(s), or valves.
Reilly has taken every precaution to
assure that each component and fitting was
thoroughly cleaned and the system purged
before
this machine was delivered.
Therefore, maintenance of the system should
be carried out with extreme care.
