The 4 casters replace the legs on the appliance to make your machine portable. Simply screw the casters into the holes below each corner of the machine. Each caster has a locking lever, which locks the appliance in place once it has been moved to the desired position. This safety feature prevents the machine from moving or rolling around.
All 4 castors lock independently. Together, the castors have a weight capapcity of up to 200 lbs.
