Electrical Installation
The control box is mounted on the front of the sharpener, under the mount pan. Electrical
connections to the control box from the cam motor and sharpener motor come preassem-
bled.
A wiring harness is provided to connect to a power source. This must be a battery capa-
ble of sustaining a 10 amp load or higher.
WARNING!
Use only the provided wire harness to connect the sharp-
ener to the power source. (It is protected by a built-in 20 amp fuse.)
The sharpener has three controls on the front panel. The up position is “on” for each of
them, and the down position is “off”. From left to right, these are:
jog switch
cam motor switch
grinder motor switch
Test the control mechanisms of the sharpener:
1.
Ensure that the switches are in the “off” position to avoid starting the motors when power
is applied.
2.
Raise the sharpener head to avoid contacting the frame with the grinding wheel.
3.
Connect power to the sharpener. Connect the red wire from the harness to the positive
terminal on the battery and the black wire to the negative terminal on the battery.
4.
Use the jog switch to rotate the cam.This should move the pusher to index the blade for-
ward.
NOTE:
When the jog switch is pressed, the cam motor will rotate the
cam assembly counter-clockwise, so that the pusher can index the
blade forward manually.
5.
Set the cam motor switch to the “on” position. The cam motor should turn on. Confirm that
the motor rotates in the direction indicated by the directional decals on the sharpener.
NOTE:
When the cam switch set to the “on” position, the cam motor
will rotate the cam assembly counter-clockwise repeatedly, so that the
pusher can index the blade forward automatically.
