The Yale / Hyster software is password protected, so you cannot use it if you have it. Password is only available for Hyster / Yale dealers.
Normally on all trucks default password has to be changed upon delivery.
The best way is to get in touch with your local Yale dealer and ask for them to come by.
This is ONLY to be used to report flooding, spam, advertising and problematic (harassing, abusive or crude) posts.
