Adjusting Blade Tension

1.Disconnect machine from the power source, unplug.

2.Turn blade tension hand wheel (A, Fig. 18) counter-clockwise to tension blade, and clockwise to loosen the tension. A gauge on the upper wheel slide bracket (B, Fig. 18) indicates the approximate tension according to the width of the blade. The JWBS-20 comes with a 1” blade so the tension should be set at 1” when using this blade.

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 and/or poor cutting performance.

Adjusting Blade Tracking

WARNING

Disconnect machine￿from the power source!

Never adjust blade tracking with the

machine running!

Failure to comply may cause serious injury!

Note: Blade tracking has been adjusted at the factory. If, however, it is determined that blade tracking needs adjustment, make this adjustment with knob (C, Fig. 19).

Do not use knobs (D, Fig. 19). They are used by the factory for wheel alignment not tracking.

1. Disconnect the machine from the power source.

2. Blade must be properly tensioned before adjusting blade tracking. Make sure upper and, lower bearing guides do not interfere with the blade while adjusting the tracking.

3. Open upper wheel door. Rotate the wheel forward, and observe the position of the blade on the wheel. The blade should rest in approximately the center of the wheel.

4. If adjustment is necessary, loosen the wing nut (E, Fig. 19) at the top rear of the saw.

5. Adjust tracking by turning the knob (C, Fig.

19) in 1/4 turn increments. Rotate the wheel forward, and observe the position of the

blade on the wheel. Rotating knob (C, Fig.

19)counter-clockwise should move the blade towards the front of the wheel. Rotating the knob (C, Fig. 19) clockwise should move the blade towards the back of the wheel.

6.Continue with adjustments until the blade is tracking properly.

7.Tighten the wing nut (E, Fig. 19) after blade is tracking in the center of the wheel.
