Cautions regarding parts removal
If a screw or shaft to be removed has been locked by
one of the above agents, remove the screw or shaft
using a general tool, such as a wrench or puller.
If it is difficult to remove the screw or shaft, heat the bolt
to soften the agent (200~250°C) using a soldering iron
or gas torch.
Caution
If there is a seal near the screw or shaft to be removed,
carefully use the heating method for removal, to avoid
damage to the seal.
If heat has been used to remove the bolt a new bolt
should be used during reassembly.
