1.Remove main input supply power to the machine.
2.With the 3/8" nut driver, remove the 4 screws that hold the handle to the machine.
3.Remove the rubber gasket (cover seal) from the lift bail.
4.With the 5/16" nut driver, remove the sheet metal screws from the case top.
5.With the 5/16" nut driver, remove the screws holding the right and left case sides. Remove the case sides by lifting up and out.
6.Perform the Capacitor Discharge Procedure described earlier in this section of the manual.
Before continuing with the test procedure, perform the capacitor discharge proce- dure to avoid electric shock.
7.After you have completed the capacitor dis- charge procedure for all four switch boards, use the 5/16" nut driver to remove the two 5/16" sheet metal screws holding the reconnect switch assembly. Twist the reconnect switch out to access the lead connections on the back.
8.Use the 3/8" wrench to disconnect the two negative leads from the reconnect switch. By disconnecting the leads at the recon- nect switch, you will not have to disturb the silicon applied to the input rectifier. Electrically isolate the leads from all other leads.
