All of our pieces go through extensive checks when they go out, and we will do all repairs that are necessary. As we cannot predict what will happen once a machine leaves, it is the responsibility of the renter to check the machine daily before each use and to do preventative maintenance. We have a service truck that can service the equipment, and most importantly, we have off-site diagnostic tools in our equipment so we can diagnose a problem if there is one with little to no downtime for the customer.
