Page 33: Face Grind Adjustment
Face Grind Adjustment 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. - Page 34 Face Grind Adjustment 7.

Page 38: 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 Wood-Mizer 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. - Page 39 Back Grind Adjustment If the back grind is too light, redress the bottom angle of the wheel, reset the gullet grind, then recheck the back grind. FIG. 4-10 6. Check the contact of the grinding wheel against the back of the tooth, and if necessary, repeat the procedure.

Page 41: Section 5 Sharpener Operation
Operation SECTION 5 SHARPENER OPERATION 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. - Page 42 Operation Any adjustments of the pusher wing nut will affect gullet grind, face grind and back grind. If you use the turnbuckle to lower the wheel for more gullet grind, you will have to dress more from the back angle of the wheel to prevent grinding the back of the teeth too heavy. If you dress the bottom angle of the wheel larger for less back grind, you will have to read- just the gullet grind with the pusher wing nut.

Blade Installation Blade Installation Before installing a blade, use the jog switch to move the pusher into the highest position that allows the blade to be installed. Install a blade: 1. Uncoil a blade and position it above the three support assemblies around the sharpener. 2. - Page 44 Blade Installation b. Slide the turnbuckle assembly off the head. c. Rotate the sharpener head back so that it rests in the most upright position. d. Lift the indexing arm. CAUTION! When disconnecting or reattaching the sharpener head, be sure to keep it supported. Do not allow the sharpener to fall. It may damage the grinding wheel or the blade, and may cause personal injury.
