GBC 450-KM binding machine: Maintenance is required for smooth and reliable function
All machines need maintenance or they will break down. My GBC 450-KM binding machine is no exception. My machine uses common plastic combs, will punch comb rectangles and bind into a booklet of varying thicknesses. Given use it will jam and will refuse to bind, so you need to open it up, trouble shoot, tighten and grease. The user manual also does not fully explain the left side controls of the machine nor any maintenance, so I thought I would embellish here.
