Parts To Be Fixed With Lock-Tite Paint - JUKI LU-2210N-7 Engineer's Manual

8. Parts to be fixed with LOCK-TITE Paint

The following parts are fixed with "LOCK-TITE" paint. When these parts are disassembled, remove residual paint
thoroughly using pint thinner and assemble them applying "LOCK-TITE" after removing any moisture from the surface.
If the screw which has been fixed with "LOCK-TITE" paint, is too hard to loosen, it is advisable to warm it up using a
torch lamp. This will make the screw easily come off.
