NOTE: The holding valve should turn by hand until
compression of the O-rings begins.
4. Carefully install the holding valve into the port block until
fully seated.
5. Test the check valve and port block by operating the lift
cylinder and/or the telescope cylinder, as applicable.
Verify lift cylinder and/or telescope cylinder works
without problems; verify there is no leaking. Make
repairs as needed.
CAUTION
Do not damage the O-rings during installation of the
holding valve. If the holding valve turns freely then gets
hard to turn, then easy to turn; remove the holding valve
and check the O-rings. They have probably been
damaged by a sharp edge of a port.
