MC CABLE CUTTER & PIGTAILER
Correct Notching Blade Rotation
(05/06/05)
A common problem we see is that users set the drill motors to turn in the wrong
direction. Our design has the blades cutting towards the cut-off (circular saw)
blade. This serves to keep the notching blades from “grabbing” the MC cable
as it is cut because they are “pushing” against the cut-off blade. Although
turning, the cut-off blade helps to hold the cable in place. The left-side blade
turns counter-clockwise as you look at it and the drill turns in the “forward”
direction. The right-side blade turns clockwise as you look at it which is the
“reverse” direction”. Refer to illustration 1. Note that the right-side notching
blade uses a left-hand (LH) nut and arbor. The right-side arbor is also pinned
to keep it from spinning off during operation.
Another problem we see is that the notching blades are installed backwards.
Refer to illustrations 2, left-side and 3, right-side. The square parts of the blade
teeth rotate toward the MC cable, not the angled parts. Also note that that the
washers should all be the same thickness to allow for consistency of cuts after
you change blades.
Yet another problem we have seen is that the trigger locks on one or both drills
can pop “off” from rough handling. This is indicated by a lack of a notch from
the affected drill(s) because the drill is not turning. We have seen hold-downs
adjusted well out of range in order to compensate for this. We have even had
machines sent back to us for this reason! Get used to the sound of a properly
operating machine such as the “zinging” sound made by the notching blades
and note when you don’t hear them. If you have trigger locks that tend to pop
off, simply use a wire-tie to hold the trigger “on”.
