UPPER BLADE GUARD (B) FIG. 27 IS

SHOWN REMOVED FOR CLARITY. ALWAYS MAKE
SURE THE UPPER BLADE GUARD IS INSTALLED AND
PROPERLY ADJUSTED BEFORE OPERATING THE
BAND SAW.

Loosen the two screws (C) Fig. 27, and adjust the

blade guides (D) as close as possible to the sides of the
saw blade, being careful not to pinch the blade. Tighten
the two screws (C).

Loosen screw (E) Fig. 27, and move the guide

bracket (F) in or out until the front edge of the guides (D)
are just behind the “gullets” of the blade teeth. Tighten
screw (E).

The upper blade support thrust bearing (G) Fig. 27

prevents the saw blade from being pushed back too far
when cutting. The support bearing (G) should be
adjusted approximately 1/32" behind the blade. The
blade should also overlap the outside diameter of the
ball bearing by approximately 1/8". To adjust:

Loosen screw (H) Fig. 28, and slide support bearing

(G) in or out until it is approximately 1/32" behind the
saw blade.

The upper blade support bearing (G) Fig. 27, is set

on an eccentric shaft. To change position of bearing (G),
use a straight screwdriver, rotate shaft (J) Fig. 28, until
the blade properly overlaps the support bearing. Then
tighten screw (H).
