FIG. 49 TIMER

Location:

The timer is located inside the rear access panel. Adjustments can be made by removing the 2” hole plug.

Test Procedure:

1.Disconnect grinder from the power source.

2.Insert the leads of a voltmeter set to read at least 120 volts AC, along side the red wire (terminal 1) and the white/black wire (terminal 2) of the harness plug. Place the Off/On/Start switch in the “ON” center position. Connect the grinder to the power source. The indication must be 120 volts AC for 120 volt models, 100 volts for 100 volt models, and 230 volts for 230 volt models.

3.Disconnect the grinder from the power source.

If voltage is present as described, proceed to step #4.

If voltage is not present as described, refer to the wiring diagram and check the grinder wiring harness.

4.Insert the positive (+) lead of a volt meter set to read at least 120 volts DC (157 volts DC on units with capacitor), along side the black wire (terminal

3)of the harness plug and insert the negative (-) lead along side the white wire (terminal 6) of the harness plug. Place the Off/On/Start switch in the “START” lower position. Connect the grinder to the power source. The indication must be 120 volts DC for 120 volt models (157 volts DC on units with capacitor), 100 volts for 100 volt models, and 230 volts for 230 volt models for the set time and return to 0 volts.

5.Disconnect the grinder from the power source.

If voltage is present as described the timer is operating properly.

If Voltage is not present as described, replace the timer.
