Eraser K8 Series Operating Instructions

OPERATING INSTRUCTIONS
SET-UP:
ALL K8 UNITS: All K8 Series units are shipped with a
spider assembly and set of four blades. Also included
will be 2 allen wrenches, 1/16" and 5/64". NOTE: It is
very important that the proper blades are used for
different wire types and sizes to ensure maximum
results. See blade selection information on previ-
ous page for proper blade selection. The first 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 - Refer to the Model K8A
Front and Side View Drawing for proper orientation of
blades and spider.
To install the blades into the spider, first 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,
first 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 off. Slide the spider
assembly with blades onto the shaft, ensuring that the 2
set screws on the spider line up with the 2 flats 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 firmly 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.
MODEL K8B: The K8B is shipped with a separate
mechanical footpedal which must be installed. When
using the footpedal, the K8B must be used on a bench
whose height ranges from 34-38 1/2" from the floor.
First, locate the hole pattern diagram in the drawing
section of these instructions. Using the pattern as a
guide, measure and mark the holes to be drilled on the
benchtop. Place the K8B over the marks and ensure that
the holes on the bench match up with the holes in the K8B

Model K8 Series Wire Strippers
(Models K8B, K8A)
base and the area containing the clevis, underneath and
behind the blades. Drill the holes in the bench. Mount the
stripper, using 1/4" fasteners, and ensure that the clevis
is hanging freely in its 5/8" clearance hole through the
bench.
Screw the threaded end of the upper rod, the one
containing the turnbuckle, into the clevis on the underside
of the bench. Then, screw the coarse threaded end of the
lower rod into the turnbuckle. Adjust the position of the
two rods with the turnbuckle so that the lower rod hangs
6" above the floor surface. Align the footpedal assembly
on the floor so that the clevis of the footpedal is directly
underneath the lower rod, and the front edge of the
footpedal base is aligned with the front edge of the unit.
Mark mounting holes on the floor and mount the footpedal
with appropriate fasteners.
Screw the lower rod into the footpedal clevis and adjust
the rods with the turnbuckle so that the footpedal is in its
highest position. Once properly set, tighten the turn-
buckle and both clevises in place by tightening the Hex
nuts on the two rods.
MODEL K8A: 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 air
supply. Mount the unit securely to the bench, and place
the electrical footswitch on the floor.
ALL UNITS: With the blades installed and the unit
securely mounted to the bench, blade adjustments may
be made for the wire to be stripped. All units contain 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 K8B, the blades remain closed
until the footpedal is depressed to open them. On the
K8A, the blades are open, and the electrical footswitch is
activated to close them.
To adjust the wheels, first 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
