The TM-20 is a 5-in-1 hand-operated trimmer that performs straight cutting, wave cutting, perforating, creasing, and corner rounding using interchangeable rolling cutter heads.
The specified cutting size is 230 × 320 mm. This comfortably accommodates A4 and A5 sheets, but it does not cut full A3 (297 × 420 mm) sheets in one pass.
Capacity per pass is: straight cut — up to 5 sheets; wave cut — up to 3 sheets; perforating — up to 3 sheets; creasing — up to 3 sheets; corner round cut — up to 3 sheets. For thicker stock, reduce the number of sheets.
Yes, but capacity depends on thickness. The sheet capacities given are for typical copy paper. For heavy cardstock, reduce the number of sheets per pass and test on a scrap to avoid dulling or damaging the cutter.
The TM-20 uses interchangeable rolling cutter heads. To change functions, lift the cutter carriage according to the user guide, remove the current head, and install the desired rolling head securely. Always follow the manufacturer’s instructions and ensure the carriage is locked before cutting.
Place paper against the back and side guides, align your cut using the ruler/scale, lower the cutter carriage if needed, then roll the cutter smoothly across the paper. For corner rounds, position the corner and roll the corner-head. Perform a test cut on scrap before finishing your job.
The product includes a cutting area and typically features edge guides and a work surface for alignment. For precise measurements, align paper to the built-in scale/guides and confirm with a test cut.
Keep the cutter carriage clean and free of paper dust. Blow or brush away debris, and wipe the surface with a dry or slightly damp cloth. Replace or sharpen blades when cuts become ragged. Avoid using solvents that could damage plastic parts.
Signs of a dull blade include tearing or frayed edges, requiring extra force to cut, or uneven/perforated cuts. Replace the rolling cutter head or blade when you notice these issues.
Replacement rolling cutter heads and accessories are usually available from GED or the seller/distributor. Check the product listing or contact the manufacturer for compatible parts and part numbers.
The TM-20 is hand-operated and safe when used properly. Keep fingers clear of the cutter path, store the unit with the cutter carriage in a safe position, and supervise children. Follow all manufacturer safety instructions.
The TM-20 is designed for manual use and small to moderate batches. For high-volume production, consider an electric or industrial cutter. For best results in longer runs, work in small batches and inspect the cutter regularly.
Yes. The creasing function produces a fold line to help with neat folds; the perforating function creates tear lines. Both have a capacity of up to 3 sheets per pass (depending on paper thickness).
Although marketed as multifunctional and referencing A3 in the name, the usable cutting area (230 × 320 mm) makes it best suited for A4 and A5 sheets and similar sizes. Full A3 sheets exceed the stated cutting dimensions.
