- About 20mg of grease (Molykote HP-300; CK-8012) should be applied
to the inner [1] and the outer surfaces [2] of the bushing until the white
coat covering is formed uniformly. If this undone, the noise (squeaking)
may occur.
- Applied grease may be transferred from the bushing to the fixing roller
ends [1] when mounting; be sure to wipe it off when this happens.
