OPERATING INSTRUCTIONS
APPLICATION
The Model 74F Coaxial Wire Stripper is designed to strip coax as well as hook- up wire up to .265″ (6.7mm) overall O.D. The Model 74F may be equiped with any combination of interchangeable Single or Twin Blade Face Plate Assemblies. Coaxial and shielded cable stripping is normally done in three stages by inserting the wire into each blade assembly in sequence. The sequence may vary depending upon cable construction and strip requirements. Selection of Face Plate Assemblies, either Single or twin Blade is dependent on the wire or cable to be stripped. Coaxial cable stripping normally requires three Twin Blade Face Plate Assemblies.
WIRE GUIDE SELECTION
Select a Wire Guide with the smallest inside diameter that slips freely over
the outside diameter of the wire to be stripped.
Standard Wire Guides available (inches):
For Single Blade Face Plate

Wire Guide Installation: Remove plastic guard. Insert wire guide by aligning hole in wire guide flange with locating pin in the faceplate. Tighten wire guide locking screw with the wrench provided.
Blade Adjustment: Loosen blade block locking screw. Set the blade to
conductor thickness. To adjust blade “in”, turn blade adjusting screw
clockwise; to move blade “out” turn counter-clockwise. Hold blade block firmly
so that blade adjusting screw is against stop block. Retighten block locking
screw.
The faceplate may be removed for blade adjustment if desired. Loosen the face
plate set screws. Push the faceplate out toward you.
When installing faceplate into head assembly make certain to keep the wire
guide locking screw lined up with clearance hole in head. Re-install plastic
guard.
TRIAL STRIP
Adjust stop rod to strip length desired by loosening thumbscrew located on the
top of the stop rod post. (The stop rod collar is used to offer a larger
target when long strips are being utilized. Reverse the stop rod, using the
machined end when short strips are desired). Turn the unit on.
Steps:
A. Insert wire through wire guide to stop rod (adjusted for strip
length).
B. Withdraw wire slightly to allow the blade to slowly close completely
on the wire.
C. Pause momentarily.
D. Withdraw wire sharply.
Note: Cycle time may be shortened as the technique is perfected.
Final Blade Adjustment: If blade contacts conductor, move blade adjusting screw clockwise (out). If slug has not been removed, turn counter-clockwise (in). Cut off trial strip and repeat if necessary. Make certain to always retighten the blade block locking screw after having made blade adjustments. These adjustments may be made without removing the faceplate.

is used to offer a larger target when long strips are being utilized, Reverse
the stop rod, using the machined end when short
strips are desired). Turn unit on.
Steps:
A. Depress push plate gently with the thumb, allowing blades to open just
enough to insert the wire.
B. With another hand, insert the wire through the wire guide to stop rod
(adjusted for strip length).
C. Allow blades to close completely on the wire by slowly removing
pressure on push plate and withdrawing wire slightly as blades grip and sever
insulation.
D. Pause momentarily with thumb off push plate.
E. Withdraw wire sharply.
Note: Cycle time may be shortened as the technique is perfected.
Final Blade Adjustment: If blades contact conductor, move blade adjusting screw counter-clockwise. If slug has not been removed, turn clockwise. Cut off trial strip and repeat if necessary. Make certain to always retighten the blade block locking screw after having made blade adjustments. These adjustments may be made without removing the faceplate.
CENTERING BLADES
Blades are factory centered, re-center only after new blades have been
installed. Unhook blade block spring, loosen centering lock screw on the front
of the faceplate, and blade block locking screw. Insert “pin” end of centering
gauge (supplied with machine) through the faceplate in the same manner as you
would a wire guide. Then turn the blade adjusting screw until both blades make
contact with the centering gauge. Tighten blade block lock screw; turn
centering screw to contact blade adjusting screw; tighten the centering lock
screw. Re-hook blade block spring, loosen blade block lock screw and turn
blade adjusting screw counter-clockwise to allow the centering gauge to drop
out. Retighten blade block lock screw. Re-install face plate, push plate, and
plastic guard.
