Back Grind Adjustment
When combined with a light face grind, back grind should remove enough material from
the tooth to regain a sharp tip (See the
Blade Handbook
for details con-
cerning blade maintenance). With the face grind and gullet grind adjusted, now dress the
back angle of the wheel to provide the desired back grind.
NOTE:
It is possible to grind a blade and not sharpen the teeth.
Closely inspect the tips of the teeth for a new, sharp tip.
NOTE:
A blade should be installed before performing this adjustment.
See Section 5.2 Blade Installation.
Adjust the back 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, advance the blade until the grinding wheel is above the back of a
tooth.
3.
Lower the sharpener head by twisting the turnbuckle until the bottom of the grinding
wheel contacts the back of a tooth.
4.
Tighten the thumbnut to lock the turnbuckle.
5.
Dress the angle (See Fig. 4-10) by doing one of the following:
If the back grind is too heavy, dress the angle on the back side of the grinding wheel
larger.
