MC CABLE CUTTER & PIGTAILER
V-Block Adjustment
(revised 07/01/14)
Proper alignment of the V-Block to notching blades is important to prevent
“grabbing” of the cable as it is cut. What happens is that instead of cutting directly
into the cable the blades cut alongside of the cable and can grab it and force it
into the cut-off saw. This can also be the cause of broken notching blade teeth.
Proper alignment is verified before shipping, but rough handling during shipping or
at other times can move the V-Block, resulting in misalignment. You may also
have to adjust the V-Block towards the front of the MC Cable Cutter & Pigtailer
when moving from a smaller diameter cable (ie: 14-2) to a larger cable (ie: 10-3).
This is due to the larger arc the notching blade must follow when cutting larger
cable. The following procedures outline the V-Block adjustment. This document
is a supplement to the Operating Instructions.
Tools you might need will be: ¼” straight slot screwdriver, 7/16” wrench, a couple
small scraps of MC cable, several feet of MC cable to test-cut with (preferably the
size you will be using).
•
Before adjusting the V-Block, mark its location on both sides of the lower
frame, front and rear, to refer to while adjusting. Also mark the center points
where the V-Block contacts the tubes. Unplug the machine, remember—
SAFETY FIRST!!!
•
Prop open the spring-loaded hold-downs about ½” with some scraps or
5/16” nuts. Remove the hold-down pads/rods noting the position of the
washers. Take two pieces of MC scrap and put them under each notching
blade.
•
Referring to figures 1 and 2, look lengthwise down the V-Block. Figure 1
shows proper adjustment. Figure 2 shows improper adjustment. The
notching blade should be centered on the MC scrap +/- 1/16”.
