The Model 220 is a sturdy machine, and its mass helps with both stability and bend resistance from repeated use. To hold the rim in place it has three solid-steel rim clamps, which can, with proper adapters, accommodate everything from an 8-inch scooter wheel all the way to a 23-inch custom hoop. To keep all the steel of the Coats machine and its parts from trading paint with your rim there are plastic guards fixed to the rim clamps and the mount/unmount tool. Tire removal is done by spinning the tool around a fulcrum pole attached to a locking vertical arm, and for getting the bead off the rim there’s an adjustable manual bead breaker in front.
