POSITIVE STOP YOKE INDEX

Yoke index lever (A) Fig. 71, activates a positive stop which positions the cutting-head in the cross-cut or rip position. To rotate the cutting-head, release yoke clamp handle, press up or down on yoke index lever (A), releasing the positive stop, and rotate the cutting-head to the #1 in-rip or #2 out-rip or #3 cross-cut positions as desired. Release the yoke index lever (A) Fig. 71, and the cutting-head will automatically index at each of the three positions above.

POSITIVE STOP BEVEL INDEX

Bevel index knob (A) Fig. 72, provides a positive stop when positioning the saw blade at zero, 45°, and 90° left, and 90° right on the bevel scale (C). To change the angle of the saw blade, loosen bevel clamp handle (B), pull out bevel index knob (A) and tilt saw blade and motor. For zero, 45°, and 90° left, and 90° right positions, release bevel index knob (A) and saw blade will index at each of these positions. Then tighten bevel clamp handle (B). For saw blade angles between positive stops, set blade at desired angle on bevel scale (C) and tighten bevel clamp handle (B) Fig. 72.

ADJUSTING SPLITTER AND ANTI-KICKBACK FINGERS

During ripping operations, the splitter (A) Fig. 73, must ride in the saw kerf and the anti-kickback fingers (B) should be touching the workpiece to prevent kickback.

1.Set the saw up in the ripping position with the blade guard lowered on the in-feed side to act as a holddown.

2.Start a piece of material through the saw as shown in Fig. 73.

3.Shut off saw and disconnect from power source.

4.Adjust the arm (C) Fig. 73, so that it is vertical and the splitter (A) is in the saw kerf.

5.If the splitter (A) Fig. 73, does not line up with the saw kerf, loosen hex nuts (D), and position splitter (A) into saw kerf as shown. Then tighten hex nuts (D) against arm (C). The straight side of the splitter should be toward the blade as shown in Fig. 73, and the anti-kickback fingers should rest on the workpiece as shown. NOTE: The clamp knob for arm (C) must be tight. Move arm (C) front to back while tightening clamp knob with other hand to be sure clamp is firmly seated and tight.

6.Pull backward on the workpiece to determine if the anti-kickback fingers bite into the material and prevent further backward movement. If necessary, readjust height of arm (C) Fig. 73.
