Face Grind Adjustment
As the sharpener operates, the cam will rotate, causing the pusher arm to contact a tooth
and move it into a position under the grinding wheel. The pusher arm can be adjusted to
leave the tooth closer to or further away from the grinding wheel so that the tooth face is
ground more lightly or more heavily.
Before adjusting the face grind, ensure all motors are turned off.
NOTE:
A blade should be installed before performing this adjustment.
See Section 5.2 Blade Installation.
Adjust the face grind:
1.
Raise the sharpener head by loosening the thumbnut and twisting the turnbuckle until the
grinding wheel clears the blade tooth.
2.
Using the jog switch, move the blade until the next tooth is underneath the grinding wheel
and the pusher is pulled away from the tooth.
3.
Lower the sharpener head by twisting the turnbuckle until the bottom of the grinding
wheel reaches the midpoint of the tooth face
4.
Tighten the thumbnut to lock the turnbuckle.
5.
Spin the grinding wheel by hand to check the amount of face grind on the tooth. The
grinding wheel should lightly contact the face of the tooth all the way up to the tip.
6.
Adjust the wing nut (See Fig. 4-8) to make the face grind lighter or heavier by doing one
of the following:
If the face grind is too light, make the face grind heavier, by turning the wing nut
counter-clockwise.
If the face grind is too heavy, make the grind lighter, by turning the wing nut clock-
wise.
