4.2. Remove the handwheel from the seat by pushing

on the seat.

4.3. Remove the O-rings (14) et (16) from the DIN

seat.

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.

ttention: 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.
