SERVICE

Send faulty equipment to a CONCOA-designated repair center for re-

pairs. Special tools and techniques are required to repair such equipment.

Personnel with experience with such equipment should perform repairs.

Shut off gas supplies at source before attempting inspection or service unless

leak testing with an approved oxygen compatible leak detection fluid.

General

Servicing is usually required if gas escapes from the hand torch when it is on

the hanger rod; test by hand pressure on the hanger rod.

If the torch and station outlet valves are closed, but the regulator indicates a

slow change in pressure when the torch is off the hook, the quad-ring seal in

the Mizer may be damaged. Damage to this seal will allow gas to escape past

the thrust pin seal. This condition may also be caused by a hose connection;

test with an approved oxygen compatible detection fluid.

Valve Seat Replacement

Send faulty equipment to a CONCOA-designated repair center for repairs.

Use only lubricants compatible with oxygen.
