10.Using the 7/16” wrench, disconnect the transformer primary leads from the recon- nect studs. See the Wiring Diagram and Figure F.18. Label the leads for reassembly.

11.Using the 5/16” nut driver, remove the one screw from the lower front corner of the glas- tic reconnect panel.

12.Remove the H1 capacitor lead from the capacitor terminal.

13.Using the 5/16” nut driver, remove the four screws from the glastic choke baffles.

14.Remove the glastic reconnect panel by lifting up on the choke baffle and sliding the recon- nect panel away from the machine. (Clear all leads.)

15.Clear the glastic choke baffle and associated leads for transformer removal.

16.With the 3/8” wrench, disconnect the H1 pri- mary lead from the input line switch.

17.Using the 1/2” wrench, disconnect the choke lead from the polarity switch. See the Wiring Diagram and Figure F.19. Label for reassembly.

18.Using the 1/2” wrench, disconnect the X1 transformer secondary lead from the polarity switch. Label for reassembly. See Figure F.19.

19.Using the 3/8” nut driver, remove the screw holding the left side internal panel to the metal lift bail baffle. See Figure F.18.
