- The blade is attached to the cutter handle by means of a nut, washer and screw. You remove the nut and washer you to get at the blade. Never handle the edges of the rotary blade. The razor-like blade can slice into your fingers and cause serious injury. Instead, turn the cutter over and tap it lightly on a table top. The old blade should drop out and onto the table. Open the protective plastic case in which the new cutter blade is stored. Flatten your hand and tip the new blade into your hand.
- Installing the new blade is now simply a matter of fitting the screw in the center of the rotary cutter into the hole in the center of the blade that lies flat in your hand. Carefully flip your hand and the cutter and the blade should settle onto the screw. Replace the washer and nut, and you've successfully changed the blade with the least risk to your fingers and hand.
-
Always put the old blade in the plastic cover in which the new blade was packaged. An uncovered blade dropped into the trash could result in serious injury to anyone who reaches into the trash to retrieve something else or even to empty the trash. Even a dull blade can still be sharp enough to inflict severe cuts. You can handle the blade by the hole in the center or slide it off the edge of the table into the plastic case.
Instead of throwing away the old blade, you can buy a tool to sharpen them. When they will no longer hold an edge, dispose of them in the plastic case.
