6.1 Blade
6.1.1 Blade Tension
Refer to Figure 8.
1. Disconnect the machine from the power source.
2. Back off the upper and lower blade guides to eliminate any contact with the blade.
3. Tighten the blade by the blade tension lever (C).
4. Rotate the blade tension hand wheel (H) until the blade is properly tensioned.
5. Re-adjust the upper and lower blade guides.
Too little or too much blade tension can cause blade breakage and/or poor cutting performance. When the band saw is not being used, release the blade tension. This will prolong the life of the blade and the tires and reduce the load on the wheels, bearings and other components.
6.1.2 Changing the Blade
Always wear gloves when handling blades. New blades are usually packaged in a coiled position. To prevent injury, uncoil them slowly and carefully while wearing work gloves and safety glasses.
Refer to Figure 8.
1. Remove the table insert (A), loosen the locking handle (B) and remove it from the work table.
2. Release the blade tension lever (C) and then open the upper and lower doors.
3. Flip to open the upper blade guard cover and uninstall the lower blade guard by loosening the locking knob.
4. Back off the upper and lower blade guides to eliminate any contact with the blade.
5. Slide the blade (D) through the split on the table (E) and the frame (F) to take off the blade.
6. Mount the new blade through the table and the frame, then place the blade over the upper and lower flywheel (G) and place the blade in the upper and lower blade guides.
7. Tighten the blade by the tension lever (C) on the back of the saw.
8. Re-install the table insert (A), locking handle (B) and the blade guards and close the doors.

6.1.3 Blade Tracking
After proper tensioning, the blade must be tracked. Tracking refers to the position of the blade on the wheels while the machine is in operation. Tracking should be checked periodically, and is mandatory after every blade change. Blade tracking is done by hand with the machine disconnected from the power source.
C
Fig. 9
Refer to Figure 9.
1. Disconnect the machine from the power source.
2. The blade must be correctly tensioned.
3. Make sure the blade guides and other parts of the machine will not interfere with the blade movement. Lower the guide post until you can see the blade through the tracking window.
4. Open the upper door to expose the wheel. Rotate the wheel by hand, observing the position of the blade through the tracking window (C).
5. If the blade tends to move toward the edge of the wheel, loosen the locking knob (A) and slightly rotate the tracking knob (B) while continuing to rotate the wheel.
6. Observe the blade through the tracking window. Rotating the knob clockwise will cause the blade to move toward the rear edge of the wheel. Rotating the knob counterclockwise will cause the blade to move toward the front edge of the wheel. This adjustment is sensitive; perform it in small increments and give the blade time to react to the changes.
7. When the blade is tracking in the center of the wheel, re-tighten the locking knob and close the upper door.
8. Tension the blade and connect the band saw to the power source. Turn it on for a brief time to observe the blade action through the tracking window.
9. If further adjustments are needed, disconnect from the power source and repeat the above procedure.

6.2 Blade Guide
The blade guides should be set so that contact between the blade and the guides will occur only when the blade is under pressure from a workpiece. To adjust the upper bearing guides for proper blade control, proceed as follows:
Fig. 10
6.2.1 Upper Blade Guide
Refer to Figure 10.
1. Disconnect the machine from the power source.
2. The blade must already be tensioned and tracking correctly.
3. Lower the guide post until the upper guide bearings are a few inches above the table.
4. Loosen the guide bearing bracket locking knob (A).
5. Slide the entire guide bracket until the front of the guide bearings (E) are about 1/64” (0.4mm) behind the blade’s gullet.
6. Tighten the locking knob (A) to secure this position.
7. Loosen both of the guide bearing locking knobs (B).
8. The guide bearing rotates on an eccentric shaft. Adjust the guide bearing by rotating the knurled knob (C), until the guide bearing is approximately 0.004” (0.1mm) from the blade.
9. Tighten the locking knobs (B).
10. Make sure all of the locking knobs on the upper bearing guide assembly are tightened when the adjustments are finished.
Do not force the guide bearing against the side of the blade. It should make contact with the blade when there is pressure from the cutting operation.
