Removing and replacing feed chains

1. Use a 4 mm hex key to remove set screws.
If sheared, remove these set screws and re-install new set
screws in the feed roller sprocket.
2. Activate the feed mechanism until the set screw is opening
downward.
3. Tap the front of the sprocket/gear with a piece of wood,
causing the head of the sheared screw to fall free.
4. Ensure the set screw hole is still aligned with the channel in
the shaft.
NOTE:
it must be removed and re-aligned. Use a
common automotive gear puller for this
purpose. Ensure that you do not place the
gear puller arms behind any of the
sprocket/gear teeth, possibly bending or
damaging them.
During the assembly process, a rust preventing varnish was
applied to the feed sprocket and the feed roller shaft.
Before replacing the feed sprocket, it is recommended:
a. This varnish be removed to assist reassembly.
b. Use emery cloth to lightly polish and remove the varnish that is on/around the shaft.
c. Lightly polish and remove the varnish that is on the inside of the hole in the feed sprocket/gear.
d. Place the feed sprocket on the shaft, aligning up the set screw hole on the feed sprocket to the channel on
the shaft.
5. Replace with a new set screw.
5.9 Removing and replacing feed chains
Each chain has a master link, which must be disassembled in order to remove the chain. The master links come
from the factory facing outward, and they are easily recognizable because they look different from the rest of the
links. See FIG. 5-10 .
Remove the master link by placing a flat tip screwdriver behind the ends of the C-clip, apply pressure, and carefully
push the C-clip off of its mounting points.
