Adjusting Blade Tension
1.Disconnect machine from power source.
2.Place tension lever in the highest position, as shown in Figure 25. Turn blade tension knob (B, Fig. 25) clockwise to tension blade. A gauge on the upper wheel slide bracket (C, Fig. 25) indicates the approximate tension according to the width of the blade. Initially, set the blade tension to correspond to blade width.
3.As you become familiar with the saw, you may find it necessary to change the blade tension from the initial setting. Changes in blade width and the type of material being cut will have an effect on blade tension. Keep in mind that too little or too much blade tension can cause blade breakage.
IMPORTANT: If the band saw is to sit idle for a period of time, place the lever in the middle position; this will help prevent blade fatigue and wheel deformation.
Adjusting Blade Tracking
WARNING
Disconnect machinefrom the power source!
Never adjust blade tracking with the machine
running!
Failure to comply may cause serious injury!
How the blade is situated upon the wheels while in motion is called “tracking”. The blade should track in the center of both wheels.
1. Blade must be properly tensioned before adjusting blade tracking. Make sure blade guides and blade bearings do not interfere with the blade.
2. Open the upper wheel guard on the band saw. Rotate the wheel forward and observe the position of the blade on the wheel. It should be in the center.
3. If adjustment is necessary, loosen wing nut (D, Fig. 25) and slightly tighten knob (E, Fig. 25) to move blade toward the rear of machine. Slightly loosen knob (E, Fig. 25) to cause the blade to track toward the front of the machine.
