You absolutely can sell your machine to someone else as long as you own it. If you are renting or leasing from us or one of our banks you are not allowed to sell until the agreement is completed. The new owner still has to enroll and complete necessary certification to use the machine. Also, the warranty is NOT automatically transferred to the new owner, but can easily be transferred for a fee of $25 ahead of time. Let us know and we can help you through the process. If you sell the machine and do not notify the company then we can not honor the warranty. This is a safety precaution to protect our clients in case their machine is stolen.
