STEP 4: REMOVE THE FOCUS GROUP - ONLY FOR F18, F21, F135
THE BELOW PROCEDURE APPLIES FOR F18, F21, F135
1 - Put in position the internal part of the focus group spanner 66067115AA and rotate it anti-clockwise so it falls in the correct thread position.
2 - Tighten the internal part of the spanner up to the end-stop. Do not apply more torque after you reached the end-stop.
3 - Put in position the external part of the focus group spanner and rotate it left or right so the two pins fit perfectly with the retainer holes.
4 - Untighten the focus group retainer with the external part of the focus group spanner.
5 - Pull straightly the focus group by the internal part of the focus group spanner. As there is an o-ring around the focus group mechanics you
need to pull with enough force. The focus group and the retainer will come out with the spanner.
6 - Put in a secure area the focus group with the spanner on onto the focus group holder 66067075AA.
