air supply. Mount the unit securely to the bench,
and place the electrical footswitch on the oor.
With the blades installed and the unit securely
mounted to the bench, blade adjustments may be
made for the wire to be stripped. The K8A contains
2 knurled adjusting wheels located on either side of
the yoke at the top of the unit. These are covered
by a guard. The front wheel controls how far the
blades are allowed to close, and the back wheel
controls how far they are allowed to open. On
the K8A, the blades are open, and the electrical
footswitch is activated to close them.
To adjust the wheels, rst remove the guard
covering them. Loosen the set screws in each
of the 2 adjusting wheels using the 5/64" allen
wrench. The 2 wheels should be adjusted so that
the blades open just far enough to admit the wire to
be stripped, and close just far enough to complete
the desired stripping, without nicking or damage
to the conductors. By restricting the movement of
the blades in this manner, they form their own wire
guide for the wire being stripped, and the operator
will nd insertion and withdrawal of the wire much
easier. Once these 2 wheels have been set in the
approximate desired location by eye, retighten the
set screws so the settings will not drift when the unit
is turned on. Replace the guard.
The strip length stop rod is located in the center of
the shaft and extends through the back of the belt
guard. To adjust the strip length rod, rst remove
the blade guard. Turn the shaft manually to locate
the set screw on the shaft. Using an allen wrench,
loosen the set screw and slide the rod from behind
to the desired location relative to the blades.
Retighten the set screw.
NOTE: If window stripping is desired when using
the four-blade head, the strip length rod may be
completely removed to allow the wire to pass
through the unit and be stripped continuously.
Replace the blade guard onto the unit.
At the top center of the unit is located the blade
pressure spring and knob. If the yoke will not
move all the way forward to close the blades, then
increase the spring pressure slightly to force more
pressure on the yoke. Conversely, if the blades will
not open all the way when the footpedal or hand

OPERATING INSTRUCTIONS
SET-UP:
The K8A is shipped with a spider assembly and
2 allen wrenches, 1/16" and 5/64". Required
blade sets must be purchased separately, see
"Blade Selection" in this manual. NOTE: It is
very important that the proper blades are
used for dierent wire types and sizes to
ensure maximum results. See blade selection
information on previous page for proper blade
selection. The rst step is to install the spider
assembly and blades onto the machine. Refer to
the appropriate instructions below for the four-
blade head.
FOUR-BLADE HEAD SET-UP: To install the
blades into the spider, rst remove each of the
4 pivot pins from the spider by loosening the set
screws holding them in place with the 1/16" allen
wrench provided. One at a time, insert the 4 blades
into the slots of the spider and replace the pivot
pins. Be sure the spider is oriented so the set
screws in the front of the spider face the tips of the
blades. Retighten the pivot pin set screws. Place
the garter spring around the notches at the back of
the 4 blades, and connect the ends of the spring
together.
To install the spider assembly with blades onto
the unit, rst remove the clear guard of the unit by
loosening the 2 screws anchoring the assembly to
the base of the unit. Slide the guard forward and
lift o. Slide the spider assembly with blades onto
the shaft, ensuring that the 2 set screws on the
spider line up with the 2 ats on the shaft. Hold
the 4 blades in a closed position while sliding the
assembly onto the shaft to ensure that the backs of
all 4 blades rest on the cone at the back of the shaft.
The spider assembly should be rmly seated against
the shoulder on the shaft. Securely tighten the 2
set screws holding the spider assembly onto the
shaft, with the 5/64" allen wrench provided, then
tighten the 2 set screws on the front of the spider
assembly. Replace the clear guard onto the unit.
The K8A must be connected to a 90 PSI air supply.
The unit’s air cylinder is supplied with a 1/8" female
NPT connector. The user must provide a 1/8" male
NPT connector and air hose connected to a 90 PSI
