System Check
A system check should be performed after making any
repairs or replacements. Eliminate all air entrapment af-
ter completing the installation(s). Operate the system at
maximum operating pressure to test for possible mal-
functions or leaks. To avoid injury during system checks:
•
Do not touch any part of the system when check-
ing for leaks.
•
Stay out of potentially hazardous areas while test-
ing hose systems.
•
Relieve system pressure before adjusting con-
nections.
Intervals for Replacements
Hose assemblies and seals used on hose fittings and
adapters will eventually age, harden, wear, and deterio-
rate under thermal cycling and compression set.
Hose assemblies and all seals should be inspected and
replaced at specific replacement intervals based on pre-
vious service life, industry recommendations, or when
failures could result in unacceptable downtime, damage,
or injury risk.
For specifics on torque specifications, and how to per-
form seal/fitting replacements, refer to

draulic Fittings
