STEP 5: FRONT ENGRAVED RING 

 

0 - Before putting back the front engraved ring, check the inner cleanliness. If necessary, blow dry air and clean it properly. 

1 - If any, align the pin positioning hole of the front engraved ring with the front engraved ring positioning pin. 

2 - Slide straightly the front engraved ring. 

3 - Tighten all the front engraved ring screws. Do not apply high torque and tighten the screws just in contact.
