After applying grease to the specified parts, wait at least
30 seconds before proceeding to the next assembly step
as it takes a while for the grease to dry.
Since the grease consists of fluoroplastic and solvent,
which are likely to be separated easily, shake the grease
bottle well before use.
Be careful with the lubrication point as well as the amount
of grease. The grease should not drip or leak after the
application.
