Caution：
・ Make sure to use a liquid gasket with the
product name above or equivalent.
・ Use an appropriate amount of liquid gasket.
・ Follow the handling precautions for the
product.
・ Do not use LOCTITE 515, 518, or FMD 127
(Loctite 5127) as they are anaerobic and do
not provide sufficient effect if there is a gap
larger than 0.25 mm {0.0098 in} between the
contact surfaces of metals.
Whenever disassembling, completely remove the old
liquid gasket on the parts and the mating parts where the
liquid gasket was used using a scraper, and clean using a
waste cloth, etc., so that any oil, moisture, dirt, etc., is
removed. After cleaning, apply the specified liquid gasket
to each location and assemble.
Note：
・ If a gasket remover is used to make the
operation during cleaning easier, it is better to
wait approximately 10 minutes after applying
before starting the removal operation.
Caution：
・ Do not apply a gasket remover to the plastic
parts and the painted parts.
Thoroughly apply a liquid gasket with the specified bead
width to one side of the contact surface.
