Wilton JWBS-16B Adjusting Blade Tension, Adjusting Blade Tracking, Upper Blade Guide Adjustment

Adjusting Blade Tension

1.Disconnect machine from the power source, unplug.

2.Turn blade tension hand wheel (E, Fig. 2) counter-clockwise to tension blade, and clockwise to loosen the tension. A gauge on the upper wheel slide bracket (F, Fig. 2) indicates the approximate tension according to the width of the blade. The JWBS-16B comes with a 3/4” blade so the tension should be set at 3/4” 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 typeFigure 2 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

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:

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

2.Open the 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.

3.If adjustment is necessary, loosen the wing nut (G, Fig. 2) at the top rear of the saw.

4.Adjust tracking by turning the knob (H, Fig. 2) in 1/4 turn increments. Rotate the wheel forward, and observe the position of the blade on the wheel. Rotating knob (H, Fig. 2) counter-clockwise should move the blade towards the front of the wheel. Rotating the knob clockwise should move the blade towards the back of the wheel.

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

6.Tighten the wing nut (G, Fig. 2).

Upper Blade Guide Adjustment

Disconnect machine from the power source, unplug before making any adjustments! Blade teeth are sharp! Use care when working near the saw blade. Failure to comply may cause serious injury!

1.Blade tension and tracking must be properly adjusted prior to blade guide setup.

2.The blade guard has been removed in Figure 3 for photo purposes only.

3.Loosen the socket head cap screw (A, Fig. 3)

and position the blade guide assembly (B, Fig. 3) so that the guides rest just behind the gullet of the blade teeth. Tighten the socket head cap screw.

4.Loosen lock nuts (D, Fig. 3).

5.Adjust guide knobs (E, Fig. 3) so guides (C, Fig. 3) rest lightly against the blade. Do not force the guides against the side of the blade. Tighten both lock nuts.

6.Adjust the blade support bearing so that it is 0.003” away from the back of the blade, about the thickness of a piece of paper. To make this adjustment loosen wing nut (F, Fig. 3) and slide the bearing and bearing post into position. Tighten wing nut.

Note: Blade support bearing should be adjusted so that the back edge of the blade overlaps the front face of the ball bearing by approximately 1/8”. If adjustment is needed loosen wing nut (F, Fig. 3) and turn the bearing shaft. Tighten wing nut.
