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.
5.  Remove timer and timer mounting bracket from 
the grinder.
6.  Remove the four #6-32 keps nuts securing the timer 
to the mounting bracket. Leave the four spacers on 
the mounting bracket studs.
7.  Place new timer over the studs on the mounting 
bracket and secure with four #6-32 keps nuts.
8.  Slip timer and timer mounting bracket under the 
two screws on the motor support plate and tighten 
screws.
9.  Locate the left and right timer dials in their proper 
place on the rear panel and secure with nuts and 
internal tooth lockwashers.
10. Place timer knobs on timers.
11. Reconnect harness plug to the terminal block on 
the timer board.
