2-1 ISHdoc112003 SETUP & OPERATION
SECTION 2 SETUP & OPERATION
2.1 Blade Support Installation
The sharpener includes three blade support arms with guide assemblies.
To install the support arms, lubricate the threaded ends of the arms with grease. Insert
one arm into the threaded holes on each side of the sharpener.
1. Each guide assembly consists of a blade support with post, a blade support without post,
two bolts, a self-locking nut, and a wing nut.
See Figure 2-1. To install the guides, join one guide assembly around the end of each
blade support arm. Face the post outward as shown. Bolt from the hexed side of the
guide assembly (these hex-shaped holes will keep the bolts from turning once in place).
Secure the top bolt with a self-locking nut. Secure the bottom bolt with a wing nut.
2. Tilt the guides on the left blade support arm slightly backward, toward the rear of the
sharpener. Tilt the guides on the right support arm slightly forward, toward the front of the
sharpener.

2.2 Blade Rest Bolt Location
The blade rests on two blade rest bolts mounted in the blade clamp plates. The bolts
insert into any of the clamp plates’ three sets of holes. Place the blade rest bolts in the top
set of holes to sharpen 1” blades, the middle set to sharpen 1 1/4” blades, and the bottom
set to sharpen 1 1/2” blades. To change bolt location, unscrew the blade rest bolts,
remove them from one set of holes and reinstall to desired set of holes. Tighten the blade
rest bolts.
See Figure 2-2.
NOTE: After installing the blade rest bolts, flex the blade support arms up or down
as necessary so the blade will remain level around the complete length of the blade.

2.3 Sharpener Head Angle Adjustment
An angled template, which includes angle for 15 degrees, is provided to check hook
angle.
Note: Refer to the Wood-Mizer Blade Handbook for recommended hook angle specifica-
tions for your sawing application.
See Figure 2-3. To adjust sharpener, place the provided template against the grinding
wheel face. Loosen the depth/back adjustment knob until the template rests on the fixed
clamp plate.

See Figure 2-4. Next, loosen the sharpener head mounting bolt and nut in the motor
mounting bracket. Loosen stop bolt and its jam nut. Tilt the sharpener head until you
reach the desired angle. Hold the sharpener head in place while retightening the sharp-
ener head mounting bolt and nut. Tighten the stop bolt and secure it with the jam nut.

2.4 Sharpener Alignment
Use the provided LTAGA-PLCBN sharpener alignment tool as necessary to achieve
accurate alignment between the blade clamp and the grinding wheel.
IMPORTANT! Do not adjust the alignment tool bolts. They
have been pre-calibrated at the factory to ensure accurate
alignment results.
1. IMPORTANT! Make sure the grinder motor is OFF. Cycle the cam until the grinding wheel
is at the tip of the tooth (about to begin face grind).
2. Remove the grinding wheel cover and sharpener arbor nut. Remove the grinding wheel.
3. Remove the blade rest bolts and moving clamp plate.
4. Install the alignment tool to the grinder motor shaft as shown below.
See Figure 2-5. Position the tool so all three gauge points are in line with the front clamp
plate. Secure the tool in position with the sharpener arbor nut.

5. Loosen the clamp adjustment bolts.
6. Position the clamp assembly so the front clamp plate touches all three tool gauge points.
Secure in position by tightening the clamp adjustment bolts.
See Figure 2-6.
7. Remove the arbor nut and alignment tool.
8. Reinstall the moving clamp plate.
9. Reinstall the grinding wheel and secure in place with the arbor nut.
10. Reinstall the grinding wheel cover.

2.5 Grinding Wheel Installation
Use a Wood-Mizer approved grinding wheel. To install:
1. Push the START button on the control box and turn the FEED RATE dial up to rotate
the cam.
2. Rotate the cam until the sharpener head is at its highest setting. Turn the FEED RATE
all the way down and push the STOP button.
3. Remove the grinding wheel cover.
4. Remove the oiler.
5. Remove the arbor nut.
6. Slide a grinding wheel onto the motor shaft.
7. Reinstall the arbor nut and hand tighten. Reinstall the grinding wheel cover and oiler.
DANGER! Make sure all guards and covers are in place
and secured before operating the sharpener. Failure to do
so may result in serious injury.
8. If the installed grinding wheel is running out axially, unscrew the arbor nut, turn the grind-
ing wheel about 15 degrees and replace the arbor nut. Then check the grinding wheel’s
rotation. If the axial runout is still present, perform the above-mentioned steps again.
Repeat them as necessary until the problem is corrected.
9. After installing and adjusting the grinding wheel, hold the sharpener head up with your
hand and turn the back/depth grind knob until you can lower the head and the grinding
wheel will not contact the blade. Carefully lower the sharpener head.

2.6 Blade Installation
See Figure 2-7. Before installing a blade, push the cam motor START switch and turn
the FEED RATE dial until the cam pivot bolt is at the 2 o'clock position.
Uncoil a blade and position above the three support assemblies around the sharpener.
Check to be sure the teeth on the portion of blade that will be under the grinding wheel
point to the right as you face the sharpener. If not, remove the blade and invert it.

See Figure 2-8. Position the blade inside the left and rear blade support posts.
See Figure 2-9. Position the blade outside the right blade guide wheel.
Holding the blade with your left hand, lift the sharpener head. Then raise and hold
the indexing arm up, loosen the blade clamping fixture and press the blade between
the clamping plates. Lower the indexing arm and the sharpener head.
Make final adjustments to the blade support arms and guide assemblies. Make sure
the blade band rests evenly on both blade rest bolts. The blade should not touch the bot-
tom of either side guide assembly. All three guide assemblies should lean slightly in the
direction the blade travels through them.

Bend the blade wiper on the left side of the sharpener so that it touches the blade.
The wiper will wipe coolant from the blade into the oil pan so it does not drip on the floor.

2-11 ISHdoc112003 SETUP & OPERATION
2.7 Face Grind Adjustment
As you operate the sharpener, the cam will rotate causing the index arm to contact a tooth
and push it to a position under the grinding wheel. The index arm can be adjusted to
leave the tooth closer to or further from the grinding wheel so the tooth face is ground
lighter or heavier.
1. Before adjusting the face grind, make sure the cam and grinder motors are off, the feed
rate dial is set at "0" and the Sharpener head is raised.
2. Install the blade.
3. Turn on the cam motor and slowly increase the FEED RATE until the next tooth is under-
neath the grinding wheel.
4. Lower the Sharpener head and check to make sure the grinding wheel lightly contacts
the entire face of the tooth all the way up to the tip.
See Figure 2-10. If the face grind is too light, turn the face grind adjustment knob out
away from the other knob. If the face grind is too heavy, turn the adjustment knob in
toward the other knob.
5. Recheck the face grind on the next tooth and adjust as needed.
