When the unit is used, stairarms are in motion or the generator is rotated by any means, the 
generator will produce potentially hazardous voltages even when the battery is disconnected.

1.

Remove the rear cover and disconnect the red battery lead from terminal M6 of the lower 
PCA.

2.

Remove the three generator mounting screws shown in Diagram 7.19.

3.

Remove the two bearing clamp screws shown in Diagram 7.20. Remove the bearing clamp.

4.

Lift the generator and remove its drive belt.

5.

Loosen all four generator mounting nuts. Loosen the locking nut on the generator’s 
adjustment bolt and thread the adjustment bolt into tab to remove tension from the 
generator’s drive belt. Remove the drive belt from the generators pulley.

6.

Remove the four generator mounting nuts. Disconnect the generator’s cable connector from 
the intermediate cable and remove the generator from the EFX.

7.

Remove the adjustment bolt and it’s locking nut from the generator’s mounting base.

8.

Thread the adjustment bolt and locking nut into the tab on the replacement generator.
