Disassembly Procedure - Aqua Lung FIRST STAGE Service Manual

DISASSEMBLY PROCEDURE

Note: Before commencing disassembly, consult
the exploded view to check the reference
numbers of all parts requiring replacement.
These parts should all be replaced by new parts
and should not be re-used on the pretext that
the regulator has seen little use since its
manufacture or since its last service.
Attention: Use only the special tool when
removing O-rings in order to avoid damaging the
seal recess. The slightest scratch on a sealing
surface could cause a leak. If a surface should be
damaged then this part should be replaced with a
new one. Do not use any pointed instrument or
metal tool to remove O-rings.
