DISASSEMBLYDISASSEMBLY
Since the regulator consists of small
precision finished parts, disassembly and
assembly are rather complicated.
For this reason, replacement of a regulator
assembly is recommended, unless there is
a special reason, but in case disassembly is
necessary for an unavoidable reason, read
through this manual to the end before
starting disassembly.

ASSEMBLYASSEMBLY
For assembly, reverse disassembly
procedures, but pay attention to the
following items.
Always repair parts that were scored at
disassembly.
Get replacement parts ready beforehand.
Mixing of foreign matter will cause
malfunction.
Therefore, wash parts well with cleaning
oil, let them dry with jet air and handle
them in clean place.
Always tighten bolts, plugs, etc. to their
specified torques.
Do not fail to coat sliding surfaces with
clean hydraulic oil before assembly.
Replace seals such as O-ring with new
ones as a rule.
