Location:
 
The timer is located in the grinder base.
Test Procedure:
1.  Unplug the grinder.
2.  Connect  a voltmeter across contacts 1 & 2 of the 
larger connector (P4) on the timer board. Plug-in 
the grinder. The indication must be 120 volts ac for 
120V models and 230 volts ac for 230V models.
3.  Unplug the grinder.
4.  Connect a voltmeter across contacts 2 & 6 of the 
larger connector (P4) on the timer board. Plug-in 
the grinder. When the control switch is in any posi-
tion except “OFF” (center), the indication must be 
120 volts ac for 120V models and 230 volts ac for 
230V models.
5.  Unplug the grinder.
If voltage is present as described, proceed to #6.
If voltage is not present as described, refer to the Wiring 
Diagram and check the grinder wiring harness.

6.  Connect a voltmeter across contacts 3 & 7 of the 
larger connector (P4) on the timer board. Plug-in 
the grinder. Momentarily press the Off/On/Start 
switch to “START” (lower) position and release. The 
indication must be 120 volts ac for 120V models 
and 230 volts ac for 230V models.
7.  Unplug the grinder.
If voltage is present as described, proceed to #8.
If voltage is not present as described, replace the 
timer.
8.  Connect a voltmeter across contacts 4 & 7 of the 
larger connector (P4) on the timer board. Plug-in 
the grinder. Place the hopper selector switch to 
the left position. Momentarily press the Off/On/
Start switch  to the “START” (lower) position and 
release. The indication must be 120 volts ac for 
120V models and 230 volts ac for 230V models and 
should remain for the approximate timer setting.
9.  Unplug the grinder.
If voltage is present as described, proceed to #10.
If voltage is not present as described, replace the 
timer.
10. Connect a voltmeter across contacts 5 & 7 of the 
larger connector (P4) on the timer board. Plug-in 
the grinder. Place the hopper selector switch to 
the right position. Momentarily press the Off/On/
Start switch  to the “START” (lower) position and 
release. The indication must be 120 volts ac for 
120V models and 230 volts ac for 230V models and 
should remain for the approximate timer setting.
11. Unplug the grinder.
If voltage is present as described, the timer is operat-
ing properly.
If voltage is not present as described, replace the 
timer.
Removal and Replacement:
1.  Separate the grinder wiring harness connectors 
from the timer circuit board.
2.  Remove the relay from the timer bracket.
3.  Attach the relay to the new timer bracket.
4.  Refer to the following illustration when reattaching
