5.Remove the worn blade and install the new blade, making sure the teeth face downward where they pass through the slot in the table.
6.Use the tension handwheel to tighten the tension on the blade.
7.Proceed with “Blade Tension” and “Blade Tracking” before operating the band saw.
Blade Tension
Rotate blade tension handwheel to the right to increase tension on the blade, to the left to decrease tension on the blade. Initially, set the blade tension to correspond to the width of your blade, as indicated on the tension gauge (Figure 6). As you become familiar with the saw, you may find it necessary to change the blade tension from the initial setting, depending on the width of the blade as well as the material being worked.
Keep in mind that too much or too little blade tension can cause blade breakage and/or poor cutting performance.
If the band saw is not to be used for a period of time, release tension on the blade – this will prolong its life. First make a note of the specific tension setting for that blade. The tension can then be
Blade Tracking
1.Disconnect machine from power source.
2.Open the top blade wheel doors.
3.Move the gear shift lever into neutral position (straight down).
4.Move the upper and lower blade guides away from the blade (see “Blade Guides”).
5.Rotate upper blade wheel by hand, observing the position of the blade as it rides upon the wheel. The blade should track as near the center of the wheel as possible.
6.If the blade does not track properly, rotate the blade tracking knob (Figure 6) clockwise to move the blade toward the front of the wheel (as viewed from the front of the saw) or counterclockwise to move the blade toward the rear of the wheel. NOTE: This will also move the blade away from or toward the stoppers on the blade guide assemblies, as shown in Figure 7.
IMPORTANT: These are sensitive adjustments; make them gradually and allow the blade time to react to the changes.
