1. Fast / Slow Button

Single click for continuous flow for both fast and slow buttons. If you have the pen in continuous flow mode, you can simply click one of the buttons once to stop the continuous flow.

2. Reverse Feature

Double click any button to reverse the strand. The pen will start to pulse. Don’t worry, the pulse helps the pen successfully reverse. If your strand is too short to reverse, while the pen is turned on and heated up, you can carefully remove the nozzle with the mini wrench and insert the unblocking tool in through the pen tip. While the reverse function is engaged, and where pushing the unblocking tool through the chamber of the pen, the short plastic strand will be pushed out of the rear of the pen.
