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.

Weight bearing capacity of each castor is 190 lbs, however pls install all 4 Castors on the machine to make it function correctly.
