SECTION 5 SHARPENER OPERATION
5.1
Operation
WARNING!
Wear eye protection when operating the sharpener. Fail-
ure to do so may result in serious injury.
After the sharpener has been assembled and properly adjusted, and a blade has been
installed, you are ready to sharpen the blade.
1.
Ensure power is connected to the sharpener.
2.
Set the grinder switch to the “on” position to start the grinder motor.
3.
Set the cam motor switch to the “on” position to start the cam motor.
4.
As a final check before sharpening the entire blade, grind a single tooth and check its
shape.
a.
Turn off the grinder motor and cam motor setting the switches to the “off” position.
b.
Check the radius, tooth height and ensure that the tip is completely sharp.
5.
Make adjustments with the turnbuckle and pusher wing nut or redress the wheel to pro-
vide the desired results.
a.
Adjust the turnbuckle so the entire tooth face is lightly ground from the tip to the
base of the tooth.
b.
Adjust the pusher wing nut so enough gullet is removed to provide the desired
tooth height.
6.
Dress the back angle of the wheel larger to lighten the back grind. Grind enough from the
back of the tooth to sharpen the entire tip of the tooth.
7.
Push the start button and turn the grinder switch on.
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.
For heavy grinds, use two light passes rather than one heavy pass. A heavy pass may
blow the fuse.
