Lower Bearing Adjustments

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

Note: Blade tension and tracking must be properly adjusted prior to bearing guide setup. Refer to the Blade Tension section (page 16).

1.Place the mode selection lever (J, Fig. 18) in the Full Tension position.

Referring to Figure 23:

2. Loosen the thumb screw (B).

This will allow the thrust bearing (A) to move freely and prevent interference with the saw blade (C) during the following steps.

Guide Gearings Adjustment

3.Loosen the locking handle (D) then turn the adjustment screw (E) to adjust the assembly forward or backward until the front of the guide bearings (F) rest just behind the gullet of the blade teeth (C and inset).

4.Tighten the locking handle (D).

Thrust Bearing Adjustment

5.With the thumb screw still loose (from Step 1), slide the thrust bearing and bearing post until the space between the bearing (A) and the back edge of the blade (C) is approximately 1/64”.

A convenient way to achieve this spacing is by placing a dollar bill folded twice (four thicknesses) between the blade and support bearing – four thicknesses of a dollar bill is approximately 1/64”.

6.Tighten the thumb screw (B).

7.Loosen the lock knob (G). Rotate the adjustment handles (H) until the guide bearings

(F)rest lightly against the blade (C). Do not force the guide bearings against the side of the blade.

8.Tighten the lock knob (G).

Check to make sure the adjustments have not changed and the bearing guides do not pinch the blade.
