Adjusting Blade Tracking

1.Place the saw arm in the vertical position and open the wheel cover (A) Fig. 17.

2.Turn on the band saw. The blade is tracking properly when the back of the blade (B) Fig. 17, is just touching the edge of the wheel flange (C). The back of the blade should not be rubbing against the flange.

3.If an adjustment is necessary the blade guide bearings and blade support bearings (E) Fig. 19 (two of which are shown) should be clear of the blade.

4.Loosen screw (D) Fig. 18.

5.With the band saw running, turn adjusting screw (E) until the blade is tracking properly making certain blade tension is maintained by turning blade tension knob. (F). The blade is tracking properly when the back side of the saw blade just touches the flange on the wheel.

6.Tighten screw (D) Fig. 18, when adjustment is complete.

7.IMPORTANT: IT IS POSSIBLE WHEN MAKING THIS ADJUSTMENT TO OVER TIGHTEN THE ADJUSTING SCREW (E), FIG. 18, AND CAUSE THE BLADE TO BE MIS-ALIGNED. If this happens, loosen the adjusting screw (E) several turns but do not remove it from its threaded hole and loosen screw (D). Turn screw (D) clock-wise until it stops but do not tighten. Then turn the adjusting screw (E) clockwise until it bottoms. Turn on the machine and turn adjusting screw

(E) clockwise a small amount at a time until the blade is tracking correctly and tighten screw (D) Fig. 18.

8.After the blade is tracking properly make sure to ad- just the blade guide bearings and blade support bearings.

DISCONNECT MACHINE FROM

POWER SOURCE.

1.The blade support bearing (A) Fig. 19, should be ad- justed so it just touches the back of the saw blade after the blade is tracking properly. To adjust, loosen screw

(B). Then tighten screw (C).

2.Adjust the other blade support bearing in the same manner.
