the key switch.
2. Perform a Lock Out/Tag Out procedure, disconnect
the battery and block the wheels.
3. Allow a few minutes time before disconnecting any
hydraulic fittings or hose assemblies to relieve the
system pressure to zero psi. When working on
hydraulic fittings, SLOWLY crack the fitting when
loosening it.

CAUTION
4. Remove the hose coupling from the defective fitting.
Use two wrenches; one wrench to loosen the hose
coupling, and one to prevent the fitting from turning.
Be prepared to clean up any oil spillage.
5. Always tag the hoses and fittings for identification. If
necessary, keep notes and put markings on parts
using a non-destructive marker.
6. Remove the defective fitting and replace with a new
fitting. Use two wrenches; one wrench to tighten the
hose coupling, and one to prevent the fitting from
turning.
NOTE
SAE fittings do not need a thread sealant. They are
straight thread and include an O-ring seal.
