1. The blade guide bearings (A) and (B) Fig. 20 should
be adjusted so they just touch the sides of the blade (C)
after the blade is tracking properly and the blade
support bearing has been adjusted. To adjust, proceed
as follows:
2. Remove the cover plate that is attached to the face
of the right guide bracket (D) Fig. 20.
3. The inside guide bearing (A) Fig. 20, is mounted to a
fixed shaft and cannot be adjusted. The outside guide
bearing (B) is mounted on an eccentric shaft and should
be adjusted so that the sides of the blade (C) just
contact the guide bearings (A) and (B). To adjust, loosen
nut (E) and turn adjusting nut (F) until proper adjustment
is made. Then tighten nut (E).
4. Adjust the other blade guide bearings in the same
manner.

ADJUSTING BLADE 90 DEGREES TO
THE TABLE SURFACE
In order for accurate work to be accomplished on your
saw the blade must be at 90 degrees to the table
surface. To check and adjust, proceed as follows:
DISCONNECT MACHINE FROM
POWER SOURCE.
1. Lower the saw arm to the horizontal position. Place
a square (A) Fig. 21, on the table with one end of the
square against the blade, as shown.
2. If the blade is not at 90 degrees to the table, loosen
the two screws (B) Fig. 21, that attach the blade guide
brackets to the guide arms and rotate both guide
brackets (C) until the blade is at 90 degrees to the table.
Then tighten the two screws (B). NOTE: CARE SHOULD
BE TAKEN NOT TO DISTURB THE BLADE GUIDE
SUPPORT BEARINGS WHEN MAKING THIS
ADJUSTMENT.
