poor stitch quality. To change or reverse the Moving
Wire Cutter, first remove the complete Cutter Block
Assembly (G20197A) from the stitcher head.
Loosen and remove the two (2) Socket Flat Head
Screws (G20216) on the front of the assembly and
pull the Cutter Block away from the G8 Head. Be
careful, the Cutter Operating Slide may spring out
from the Cutter Block Assembly. Loosen the Flat
Head Machine Screw (G20214) securing the Cutter
to the Slide and rotate the Cutter until a new cutting
surface is exposed. If there are no more sharp edges
available, remove the Screw completely and install a
new Moving Cutter. Replace the Machine Screw and
be sure to tighten it completely so that the Cutter
does not rotate on the Slide.
Make sure the Cutter Operating Spring (G20210)
is resting against the Spirol Pin (G20217) in the
Cutter Block Assembly. Compress the Spring with
the edge of the Cutter Operating Slide and return the
Slide to its position in the Cutter Block Assembly. Support the Operating Slide by holding the back
of the Cutter Block and line up the two (2) Dowel Pins (G20223) in the back of the Assembly with
the Cutter Block Slide Plate (G20202). Replace the two (2) Socket Flat Head Screws and make sure
there is little or no play in the Assembly.
Like the Moving Cutter, the Fixed Wire Cutter (G20200) can be rotated when the cutting surface
is worn or replaced when no sharp surfaces are left. The complete Cutter Block Assembly has to be
removed from the Stitcher Head again by removing the two (2) Socket Flat Head Screws. Remove
the Cutter Operating Slide from the Cutter Block to reveal the Fixed Cutter. Loosen, but do not
remove, the Socket Head Cap Screw (G20196) on the front of the Cutter Block which secures the
Cutter. Rotate the Cutter until a new surface is exposed or replace it completely worn. The Cutter
can be rotated three or four times before needing to be replaced. Once the Cutter has been rotated
and before tightening the Cap Screw to secure the new position, make sure the Fixed Wire Cutter is
aligned correctly within the Cutter Block.
In order to obtain a clean edge on the cut wire, there can be no gap between the Moving and Fixed
Cutters. Replace the Cutter Operating Slide and compress it against the Cutter operating Spring until
the Moving Cutter just passes the hole in the Fixed Cutter. While holding this position, push the
Fixed Cutter against the Moving Cutter, using a small screwdriver as a lever. Tighten the Cap Screw
to secure the position of the Fixed Cutter, but be sure to test it once before re-assembling the Cutter
Block to the G8 by compressing the Cutter Operating Slide. The Moving Cutter must pass the Fixed
Cutter freely and with no visible gap.
Attach the Cutter Block Assembly on the G8 by aligning the Cutter Block with the Slide Plate and
replacing the two (2) Socket Head Flat Screws, being careful to support the Cutter Operating Slide.
