#1877 Single Blade Face Plate Assembly

SET UP

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 a clearance hole in the 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:

1. Insert wire through wire guide to stop rod (adjusted for strip length).
2. Withdraw wire slightly to allow the blade to slowly close completely on the wire.
3. Pause momentarily.
4. 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.

Steps:

1. Depress the push plate gently with the thumb, allowing blades to open just enough to insert the wire.
2. On other hand, insert the wire through the wire guide to stop the rod (adjusted for strip length).
3. 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.
4. Pause momentarily with thumb off push plate.
5. 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 a 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 to center 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 faceplate, push plate, and plastic guard.
CAUTION
Always operate with the plastic guard in place over the head assembly. Never insert anything but insulated wire into the faceplate or blade damage may occur.
