Replacement of the Feed Mechanism Assembly
(See Auto Arm Assembly)
Installation:
Set the feed spring over the pin inside the arm.
Make sure the grinder motor cable is routed
through the rectangular hole in the feed
mechanism block.
Place the free end of the grinder motor cable
into the boot opening.
Guide the feed spring into the hole of the feed
mechanism housing and carefully lower the
feed mechanism into the arm.
With the feed spring in its’ pocket, carefully
lower the feed mechanism so the spring
compresses into the pocket.
Align the feed mechanism over the two locating
pins inside the arm and hold in place with one
hand while installing the two flat head screws
through the top of the arm.
Check to see that the grinder motor cable is
below the wires coming from the feed motor
and the optical switch is under the lead-screw.
Tighten the two flat head screws.
Position the optical switch above its mounting
holes and set the screws into the mounting
holes.
Screw down the optical switch.
Install the platform.
Check that the wires inside the arm are routed
away from the optical switch and away from the
lead-screw. The wires should be as close to the
side wall of the arm as possible. The spiral
wrap end should be just inside the arm pocket.
Place the cover onto the arm, aligned with the
two pins.
Install the four flat head screws and tighten.
Install the four hex head screws and tighten.
Install the handle.
Install the autoarm assembly back onto the
machine.
