If the bows and wire are not installed properly, the cutter will not heat. We suggest reinstalling the bows and wire according to the following instructions.
Install Bows - Insert one of the bows into one of the guide holes on the handle. Press the bow down until the spring engages. The bend in the bow and the top of the guide should be level. Hold the bow in place and tighten the thumb screw. Repeat with other bow. When both bows are installed they resemble an American football goalpost. Make sure thumbscrews are not overly tightened.
Install Wire - Start with a 6-inch piece of wire. Install wire with or without the collars. When installed, wire must be taut between bows.
Without Collars - Wrap ends of wire several times around grooves in bows. Then, wrap the wire back around itself to secure.
Collars - Thread one end of the wire through the small, center hole in a bow collar and extend it out the top hole, approximately 1-inch. Twist the wire tightly several times around long wire section and secure close to edge of collar. Thread the other end of the wire through center hole in opposite collar and secure in same manner. There should only be a single piece of wire between the bows.
Make sure the wire is taut between the bows. To help get the wire tight, pull bows in slightly while securing the wire. To tighten loose wire, twist a collar slightly.
Using the Cutter - Plug the unit in. Make sure the transformer is secure in the handle and it is plugged into a working outlet.
IMPORTANT - The yellow button must be pushed firmly forward to heat the wire while cutting. The wire heats only when the yellow button is fully engaged. As a safety feature, the wire cools as soon as button is released, even the slightest amount. Make sure to maintain steady pressure. To ensure the bows and wire maintain the proper connection, make slow and steady cuts. Release yellow button when cut is complete.
