Removing the Cutter Lever
Step 1: Open the Toolhead Front Cover
Open the toolhead cover by pinching it from the sides near the bottom and pulling. Place the filament cover on top of the toolhead and out of the way, being careful not to pull on the wires still attached.

Step 2: Release the Cutter Lever
Slightly depress the filament cutter lever with one hand wile unscrewing the locking screw with the H2.0 Allen key.
Once the screw is loosened enough, rotate the filament cutter away from the toolhead completely.

Step 3: Remove the Cutter Blade
Remove the cutter from the lever with tweezers, being very careful not to touch the sharp cutter blade. The cutter should be moved to the left so its pins slide out the open side of their slots to release it.

Step 4: Remove the Cutter Lever
The circular locking clip can suddenly pop out during removal, so be prepared for the clip's release.
Use a tool to carefully push the circular locking clip off of the filament lever pin. Be sure to have a firm grip on the clip with either your hand or the tweezers and pull it the rest of the way off.
Remove the washer and pull the filament cutter lever off of its pin. Remove or otherwise keep track of the radial spring which remains on the filament lever pin.
