Installing Hydraulic System Components at the begin-
ning of this section.
3. Thoroughly clean hydraulic hose ends and fittings on
lift cylinder to prevent hydraulic system contamination.
4. Label all hydraulic connections on lift cylinder for as-
sembly purposes.
CAUTION
Operate all hydraulic controls to relieve system

draulic oil (see Relieving Hydraulic System Pres-
sure in the General Information section of this
Chapter). Also, make sure that rear attachment is
fully lowered before loosening hydraulic hose
connections at lift cylinder.
5. Disconnect hydraulic hoses from lift cylinder. Allow
hoses to drain into a suitable container.
6. Put caps or plugs on disconnected hoses and fittings
to prevent contamination.
