Edging to be trimmed must be cool and firmly adhered. Place the Edge Trimmer on end of edge to be trimmed. Apply steady pressure while smoothly sliding the trimmer the length of edge as shown in the drawing above. The trimmed excess will peel up and out the trimmer slot.
Remove screw and open unit to swap or replace blades, as shown in #2. Be sure to place blades over posts with the flat sides up. Sharpened edge must face outward.
NOTE: The two cutter blades are interchangeable for longer life. Use only single bevel mat cutter blades: .015 x .75 x 1.75”. (Available in most home centers, hardware, art supply and hobby stores.)
