The UX441N footlift handle extension allows you to offset the original handle so that it will not interfere with a swing-down edge guide.
It’s a simple part that you can make yourself if you like. I described how to do it here
UPDATE August 2021: I’ve upgraded this extension using a stronger silver-colored steel collar with larger M6 set screws. The new version is considerably stronger than the old one.
UPDATE JANUARY 2022: Two Cobra Class 4 users reported that this part did not fit their machine. Please do not order this part if you have a Cobra Class 4.
Removing the existing handle from the shaft should be easy, just loosening two set screws and sliding the handle off the shaft.
Alas, sometimes it’s not that easy. Some manufacturers use Lock-Tite or similar superglue during the assembly process to make sure the handle doesn’t come loose - ever!
If your handle is screwed AND glued in place like on my Cowboy CB-3200, you may need to use Acetone (e.g. nail polish remover) or heat to break down the glue. Clean up the shaft and inside diameter of the handle collet that goes onto the shaft with acetone or fine sandpaper. Tolerances are tight and the parts are hardened. A bit of hard superglue in the wrong place can make it hard or impossible to get the handle collet onto the extension shaft.
In general, most people manage just fine and can install the extension in a few minutes without running into difficulties.
