ADJUSTING LOWER BLADE GUIDES AND BLADE SUPPORT BEARING

The lower blade guides and blade support bearing should be adjusted at the same time as the upper guides and support bearings as follows:

DISCONNECT MACHINE FROM POWER

SOURCE.

1.Loosen two screws (A) Fig. 24, and move guides (B) as close as possible to the sides of the blade, being careful not to pinch the blade. Then tighten the two screws (A).

2.The front edge of guide blocks (B) Fig. 24, should be adjusted so they are just behind the “gullets” of the blade teeth by loosening screw (C), and moving assembly (D) in or out as necessary. Then tighten screw (C).

3.The lower blade support bearing (E) Fig. 24, should be adjusted to support the rear of the blade during the cutting operation and also prevent the blade from being pushed too far to the rear which could damage the blade. The support bearing (E) Fig. 24, should be set about 1/32" behind the blade by loosening screw (F) Fig. 24, and moving shaft (G) in or out. Then tighten screw (F).

4.The lower blade support bearing (E) Fig. 24, should also be adjusted so the back of the blade overlaps the outside diameter of the ball bearing by approximately 1/8". The blade support bearing (E) is set on an eccentric shaft.To change position of bearing (E), loosen screw (F) Fig. 24, and rotate shaft (G) Figs. 24 and 25, until the blade properly overlaps the support bearing. Then tighten screw (F) Fig.24.

TILTING THE TABLE

The table can be tilted 45 degrees to the right. To tilt the table, loosen lock handle (A) Fig. 26, and turn knob (B) clockwise until desired angle is established. Then tighten lock handle (A). NOTE: The table lock handle (A) can be repositioned by pulling out on the handle and repositioning it on the nut located underneath the hub of the handle. A scale (C) and pointer (D) are provided to indicate the degree of tilt.
