SECTION 4 SHARPENER OPERATION
4.1
Operation
WARNING!
Always wear eye protection when operating
the sharpener. Failure to do so may result in serious injury.
After the sharpener has been assembled and properly adjusted, you are ready to sharpen
the blade.
1.
Push the start button, open the oil flow control valve, and turn the grinder switch on.
Slowly increase the feed rate to begin the blade moving.
2.
As a final check before sharpening the blade, grind a tooth and check its shape. Push the
stop button, close the oil flow control valve, and turn the grinder off. Make sure that the tip
is completely sharp. Make adjustments with the face and back/depth grind knobs to pro-
vide the desired results.
NOTE:
A bottle of red dye is supplied. Brush the tooth with
die before grinding. This will assist you in seeing how the
grinding wheel is contacting the tooth so you can make the
appropriate adjustments.
3.
Push the start button, open the oil flow control valve, and turn the grinder switch on.
Increase the feed rate to a moderate speed. How fast you can grind will be determined by
how much material you are removing from the blade.
To reduce the risk of premature blade fatigue from hairline cracks, it is important to thor-
oughly clean the gullet during resharpening. It may be necessary to lightly grind the blade
twice (using a light face, back and gullet grind each time) to thoroughly clean the gullet.
Also, if a heavy grind is required, it is best to go around the blade lightly twice rather than
try to grind heavily once. If you try to grind too heavy, the breaker at the back of the con-
trol box will pop. Wait 15 seconds and push the breaker in to reset.
