Changing the Blade on the Vinyl Cartridge

Open up the package of Vinyl Blades and carefully pull off the rubber cover from the tip of one of the Blades. 

Holding the Vinyl Cartridge in one hand, push on the Plunge Rod on the back of the cartridge to expose the blade channel. 

Carefully remove the current Blade from the cartridge by grasping it and pulling it straight out.

Insert the fresh blade into the channel with the point and edge of the blade sticking out of the channel.

Release the pressure on the Plunge Rod and allow the blade to retract into the Vinyl Cartridge.
