STEP 2: REMOVE THE FRONT ENGRAVED RING
This step is mandatory for F18, F135, F200.
IMPORTANT:
even if for the rest of the Optimo Prime series this step is not mandatory, the front group and front group screws access is easier
when the front engraved ring is removed. See below the two pictures on the right showing the front group screws accessibility differences. We
recommend removing the front engraved ring systematically to reduce risks of screw drop and secure the front group repositioning.
The below procedure applies for all Optimo Primes. Only the number of screws varies. Screws are silver Phillips type.
1 - Untighten the front engraved ring screws with an adapted size Phillipps screwdriver and remove them one by one with cautious and securely
using a pair of tweezers.
2 - Pull out straightly the front engraved ring.
