9. The blade support bearing should be adjusted
so that the back edge of the blade overlaps the
front face of the ball beari ng appr ox imately 1/8".
To change position of the bearing, remov e
screw (H, Fig. 19), and bearing (G, Fig. 19), and
back off knurled knob (F, Fig. 19) c om pletely to
remove the bearing shaft. Notic e t he bearing
holder on the shaft is eccentric. Re-install the
bearing shaft, the bearing, and the screw.
Examine the overlap between the bearing f ace
and the blade. Change the position of the
bearing shaft until the overlap i s approximately
1/8".
1. Disconnect machine from the power so u rce.
2. Blade must already be tensioned and tracking
properly.
3. Loosen thumb screws (A, Fig. 20) and move
guide blocks (B, Fig. 20) as close to blade as
possible without pinching it.
4. Tighten thumb screws (A, Fig. 20).
5. Loosen thumb screw (C, Fig. 20) and turn

bearing, and the screw. Examine the overl ap
between the bearing face and the blade.
Change the position of the bearing shaft until
the overlap is approximatel y 1/ 8". Re-tighten
