WARNING:

Never oil or grease oxygen equipment. Oils and grease oxidize readily,
and in the presence of oxygen, will burn violently. Vac Kote is the oxygen
service lubricant recommended (Stock No. 6700-0092-200) if the use of a
lubricant is specified.
Periodically (at least once a year) lubricate the Tee handle screw threads with a small
amount of oxygen service lubricant. This prolongs their life and makes sealing of the
yoke gaskets easier.
(See Figure 3-9)
Periodically (at least once a year) replace the yoke check valve strainer nipples before
they become clogged with lint or dust.
CAUTION:
w
Open cylinder valves S-L-O-W-L-Y to avoid damaging regulators.
When installing fresh cylinders, briefly open then immediately close the cylinder valve to
blow any foreign matter out of the valve outlet. Do not use excessive force on the shut
off valve. Remove the old gasket and use a clean, new gasket (Stock No. 6600-0152-
400) in its place.
5.5 Battery Test
The maintenance-free battery should be tested regularly and replaced if necessary.
Refer to Section 2.3 for testing the battery. The battery has a two year replacement
schedule. Refer to the Service Manual for battery replacement.
