3. Adjust lower guide and thrust bearings below
table, using similar procedure as for upper
guides.
Movement summary: Loosen locking lever (G)
to move guide bracket using dial (H)(Knob J
must be tight). Loosen knob (K
guide bearings using knob (L1,L2). To adjust
thrust bearing loosen (J) and rotate dial (H).
4. Make sure all screws, knobs and lever are
tightened when adjustments are complete.

NOTE: The locking lever (G, Figure 31) can be re-
positioned for convenience. Simply pull out on lever,
rotate it on hub, and release it. Make sure it re-seats
itself on hub.

10.9 Guide post

Refer to Figure 32.
1. Disconnect band saw from power source.
2. Loosen lock handle (A) and raise or lower guide
post by rotating handwheel (B).
3. Position blade guide assembly so that bottom of
guide bearings are about 3/16" above material
to be cut. Or, simply lower guide post until scale
pointer (C) indicates the height of your
workpiece. This provides minimal clearance
between workpiece and bottom of guide
bearings, which will minimize blade deflection
as well as enhance operator safety.
4. Tighten lock handle (A).

10.10 Guide post parallelism

The guide post should be parallel to blade
throughout the vertical travel of the guide post; thus
the guide bearings will maintain their relationship to
the blade at any height from the table and won't

10.11 Resaw pin

Refer to Figure 33.
A resaw pin is provided with the band saw. It
provides a single contact point while ripping a
workpiece into thinner boards.

Disconnect band saw from power source.
Move blade tension lever to "Full Tension"
position.
The guide bearings in low position should
already be set in relation to blade (sect. 10.6.1).
Also, table should be square with blade (sect.
10.2).
Loosen lock handle (A, Figure 32) and raise
guide post to a high position.
Confirm that guide post travels straight up and
down, and the guide bearings maintain their
relationship to blade.
If guide post does not move straight up and
down (blade begins deflecting when guide post
is raised), slightly loosen four screws (D, Figure
32).
Left and right adjustment is accomplished using
a combination of the four screws (D);
forward/back adjustment is accomplished using
the set screws (E).
When finished adjusting, securely tighten
screws (D).
Re-check setting by raising and lowering guide
post.
