Power Supply

14-3

P/N 108755-US, Manual revision: AA

1.

Disconnect all plug connectors from the power supply. 

2.

Unscrew the four mounting screws and install the new power supply with 
the same orientation. 

3.

Attach the extender harness. With the motor installed and the shroud 
mounted, start the Shaker rocking. Adjust RV1 so that the Shaker rocks at 
38 rpm (±5 rpm). In later versions, no adjustment is required, as RV1 is 
replaced with a fixed resistor (R6).

4.

Remove extender harness and reattach all connector plugs. Reinstall 
chassis assembly and base plate.
