Adjustments:
CUT-OFF SAW: The 7” Hitachi cut-off saw now supplied with the MC Cable Cutter & Pigtailer
is fitted with a 7” continuous-rim diamond blade. This blade will last for a long time and does
not get significantly smaller as it wears. A 7” fiber blade can also be used for harder
materials such as conduit or rebar. Initial adjustment of the saw is at the bottom of its travel.
To raise the saw to change the blade, loosen the adjustment lever and pull it “up” then lift the
saw up and re-tighten the lever while you change the blade. Note that “label side in” allows
for the proper rotation of the diamond blade.
SPRING-LOADED HOLD-DOWNS: The depth of cut should be checked initially and
occasionally during operation to avoid damage to the cable insulation. This is adjustable by
loosening the wingnut on the top of the spring-loaded hold down plunger and turning the
lower, adjustment nut up or down as needed. Moving the nut “Up” will decrease the depth of
the cut and “Down” will increase the depth of the cut. Only turn the nut one or two “flats” at a
time (1/6 to 1/3 of a turn), lock the adjustment, and test-cut a piece. Be sure the hold-down
pads stay aligned lengthwise with the V-block. Proper adjustment is when the armor is
barely cut all the way through and a small “snap” is heard as you use minimal effort to twist
off the scrap.
NOTCHING BLADES: The standard, “coarse” 60T blades are black-oxide coated, high-speed
steel with a slight kerf and last indefinitely when used with aluminum-jacketed MC. The
optional, “fine” 132T blades are precision ground and hardened with no kerf. These work the
best with steel-jacketed cable and may clog when used with aluminum-jacketed cable. Be
certain that the rotation switches on the drill motors remain in position to cut towards each
other. When blades are changed, observe placement of washers. Remember, the right side
blade is held by a LEFT-HAND nut to prevent accidental loosening. Refer to the document
“Correct Notching Blade Rotation” for more information.
MICRO-SWITCH CAM: The micro-switch should turn on the cut-off saw and pigtail cutters
just before contact. This allows them to spin up and avoids lugging of the machine. The
micro-switch cam may be loosened and adjusted if necessary. You can also manually
depress the micro-switch with the machine open to check for proper drill and saw operation
being careful not to contact the moving blades. Clearance between the roller arm and
microswitch body is .035” (the thickness of a paper clip).
V-BLOCK: If the notching blade develops a tendency to grab or roll past the cable rather than
cutting squarely, the V-block may be adjusted to center the notching blades on the cable.
Refer to the document “V-Block Adjustment” for the complete adjustment procedure.
Warranty:
There is a one-year warranty on the machine and most components (see website for details).
