Yes. Everything I make that requires the customer to open up a machine, comes with fully illustrated and detailed installation instructions, which are available after purchase. I also e-mail customers a copy of all relevant literature, shortly before their purchase is shipped, as I'm always worried that people might miss the download link.
Items like my TCI Type 1 which are supplied fully assembled, also have literature but as opposed to an installation manual, a user guide is made available.
I appreciate that if English isn't your first language, things might not always be clear. But don't worry. I'm always happy to help so please don't hesitate to contact me if you get stuck or have any questions.
