Adjusting Upper Blade Guide Assembly
In Figure 19, the blade guard has been removed for
clarity.
Never operate the Band Saw
without all guards in place and in working
order.
Referring to Figure 19:
1. Disconnect machine from power source.
2. Loosen lock knob (A) and raise or lower the
upper blade guide assembly (C) to just above
the material being cut.
3. Tighten lock knob (A). Make sure blade guide
blocks (D) are still flat to the blade. If
adjustment is necessary, loosen
lock knob (A)
and rotate the assembly until the guide
blocks (D) are flat to blade.
If movement of the blade guide assembly seems
“stiff” when being raised or lowered, it can be
adjusted to slide more easily. This is controlled by
an internal spring and ball that provides varying
degrees of resistance against the guide post.
To adjust tension on the spring:
4. Remove the knob (A).
5. Using a 5mm hex wrench, tighten or loosen the
setscrew (B) until desired tension is reached.
6. Reattach and tighten the knob (A).

blocks (B) as close to the blade (C) as possible
without pinching it.

5. Loosen thumbscrew (D) and move the guide
block bracket (E) in or out until the front edge
of the guide blocks (F) are just behind the
"gullets" of the saw teeth.
