Tools Required: 2 mm, 3 mm, 4 mm handle Allen,
4 mm L Allen, #3 fl at screwdriver and #2 Phillips
screwdriver.
1. Loosen set screw on top of cover (position A in
Figure 2.1). Rotate the 3-hole thread guide to allow
access to the frame screw (Figure 2.2), then re-snug

3. Before removing the C-pod, use a grounding mat
and wrist strap. Connect the two ground clips to the
bare threads of the hopping foot.

Caution: Make sure the machine is unplugged from
the wall before removing the C-pod or whenever
working on the machine.

5. With the machine properly grounded to a ground-
ing mat, and with a ground wrist strap
(Figure 2.4),
carefully unplug the cables from the C-pod. Be
careful not to touch the circuit board or damage the
cables or plugs. They should be pulled straight out by
the connector housing. (Page 13, Figures 2.6-2.8)
Note:
The plugs are labeled and keyed on the C-pod
circuit board. See
Figures 2.6- 2.13
for reconnection
information.
