If the blade cartridge should release from the cutting arm, follow these steps to ensure its proper installation:

• Locate the small recess on the far right-hand side of the 12-inch trimmer’s translucent cutting arm. This is the one and only location where the blade cartridge can be installed.

• Insert the blade cartridge pegs into the cutting arm groove. The L-shaped back wall of the cartridge will slide and lock onto the translucent arm. (Note: The blade could be damaged if incorrectly forced into the cutting arm.)

• You should feel three slight bumps as you slide the blade cartridge back into its cutting position. These are the locking bumps that prevent the blade cartridge from detaching from the cutting arm.
The blade cartridge should glide smoothly on the cutting arm when properly installed, providing your customers with hundreds of quick and easy cuts for their album-making projects.
