Case Back Screw
Remarks on the adhesive
•
The case back screw is fixed by using the adhesive.
•
Use the "LOCTITE 241" of Loctite Corporation to fix the screws.
•
Never use any other adhesive but "LOCTITE 241" in the market place or any joining material for band
adjustable screw (S-312), otherwise it may cause difficulties when unscrewing or poor water
resistance when screws become loose because of some unexpected shocks.
How to glue and fix the screws
1. Remove water drops, oil contents, dust and dirt from the
screw and screw hole on the case.
2. Apply appropriate amount of the adhesive to a screw as
illustrated at right.
3. Tighten up the screw securely with a torque driver (bit size:
T5).
• When tightening the screws up, tighten the screw one after
another in diagonal order.
• After tightening up all the screws, retighten all of them once
again to fix them even more securely.
4. Leave them for approximately 24 hours under normal
temperature so that the adhesive becomes dry enough and
the screws get fixed securely.
