My GR8 blade is not moving!

This could be for one of few possible reasons.

1. There is something jamming the blade mechanism. When cutting fibrous material or sticky tape material may get caught in the blade cavity. This is not a problem and can be easily removed by moving the handle back and forth and/or picking the caught material out. It is extremely rare that something would jam the mechanism so that the blade will not move at all. However, should this occur, remove the blade according to our instructions – and ensure that the blade cavity is clear. Also ensure that the blade is clean and free from tape.
2. You are holding the body of the GR8 as well as the handle. Ensure that you only hold the handle of the GR8 and the blade will move automatically when it meets resistance.
3. You are cutting light materials. The blade only moves when it needs to. If you are cutting light shrink-wrap, it is likely that the shrink-wrap will not create enough tension to move the blade – especially when the blade is new and very sharp.
