5/Disassembly and Repair
D. Strainer Replacement
Periodically (at least once a year) replace the
strainer nipples before they become clogged with
lint or dust.
The strainers are located in the cylinder yokes of
the gas supply modules. Remove the gas cylinder, if
present. With the yoke gate swung out of the way,
use a flat-tip screwdriver to unscrew the strainer.
Screw the replacement strainer (Stock No. 0206-
2806-725) snugly into place.
Install yoke plugs (Stock No. 0206-7129-525) and
gaskets (Stock No. 0210-6460-300) on unused yokes
to prevent dust and lint from accumulating in the
strainers or leakage occurring between the check
valves.
The tee handle screw can be unscrewed from the
yoke gate and replaced if necessary. Order Stock
No. 0219-3372-600.
E. Check Valve Replacement
Replace the check valves in the gas manifold when
reguired. The check valves are located in the cylin-
der yokes of the gas supply modules.

WARNING: Do not use oil or oil bearing materials
on or near the regulator. Oils and greases oxidize
readily and, in the presence of oxygen, they will
burn violently. All metallic parts of the regulator
must be discarded if contaminated with oil or
grease.
1. Disconnect the oxygen pipeline connection and
remove the oxygen cylinders. :
