Tsubaki Nylon Chain Coupling User manual

Hello! I've reviewed the user manual for the Tsubaki Nylon Chain Couplings, including the Standard, E, and H types. This manual provides important safety guidelines and detailed installation and removal instructions. It also notes necessary precautions for low temperature handling for Standard/E type and replacement of joint pins after removal. I’m ready to help answer your questions regarding these couplings.
What is the recommended temperature for installing or removing joint pins for Standard and Type E couplings?

Is it possible to reuse the joint pins?

What should I do before starting any installation, removal or maintenance of the coupling?
