Regarding the term "LEISTER"

On Friday, I brought an Italian guest, who sold a machine to us but the machine can't work well, to visit our work shop. It's hard for me to have oral translation their professional terms(related to industrial conveyer belt) due to the fact that only 1.5 month I have worked in the company.

The Italian run bussiness in the mainland China, but he still can’t speak Mandarin, only English for communication. We ask him flying to Taipei to solve the machine problem

Do you know "LEISTER" which is a Swiss brand name because it’s so famous that people use it referring the industrial Hot-air generator. I didn't know about this. So I translate it with its original meaning "leister". I looked into a on-line dictionary and find "a fish fork/ trident/ fish spear" to explain "leister". While they understood finally, I got so embarrassed.
