Section 1 – Scheduled Maintenance Maintenance and Inspection Schedule
1.2-5 Maintenance Hints
Three simple maintenance procedures have the
greatest effect on the hydraulic system performance,
efficiency and life. Yet, the very simplicity of them may
be the reason they are so often overlooked. They are
simply these:
1.
Change filters annually. The filters will need
to be changed more often depending on the
operating conditions. Dirty, dusty, high moisture
environments may cause the hydraulic system
to be contaminated more quickly.
2.
Maintain a sufficient quantity of clean hydraulic
oil of the proper type and viscosity in the
hydraulic reservoir.
3.
Keep all connections tight.
