9.3 Vise positioning

9.3.1 90-degree cut
Keep hands away from blade
while adjusting vise. Do not make any
adjustments to vise while the machine is
running.
1. Make sure fixed jaw (D, Figure 15) has been
squared (section 9.2, Squaring blade to
vise).
2. Position workpiece against fixed jaw.
3. Loosen screws (E) on floating jaw, and use
handwheel (F) to bring floating jaw into
contact with workpiece, allowing it to
conform to the shape.
4. Tighten screws (E).
5. Tighten clamping pressure with handwheel.

9.3.2 Miter cut
1. Loosen screws on fixed jaw (C, Figure 16),
and floating jaw (E).
2. Swing both jaws to match desired angle on
scale (G). Tighten screws (C).
Note: The angle scale is sufficient for most
mitering operations. If greater precision is
needed, verify setting with a protractor.
3. Loosen screws (E) on floating jaw, and use
handwheel (F) to bring floating jaw into
contact with workpiece, allowing it to
conform to the angle.
4. Tighten screws (E).
5. Tighten clamping pressure with handwheel.
9.3.3 Extended capacity
1. Remove two screws (C, Figure 16).
2. Reposition fixed vise in the secondary holes
(H).
3. Reinstall screws (C) and tighten.

9.4 Setting feed rate

The feed rate of the blade into the workpiece is
important to band saw performance. Excessive
pressure of blade against the workpiece may
break the blade or stall the saw. In contrast,
insufficient pressure rapidly dulls the blade.
The hydraulic cylinder resists movement of the
bow in the downward direction. It offers no
resistance when the bow is raised.
To increase feed rate, turn dial (A, Figure 17)
counterclockwise. To decrease, turn clockwise.
To close hydraulic flow, turn lever (B) down,
perpendicular to cylinder, as shown in Figure 17.
To open hydraulic flow, turn lever (B) parallel to
cylinder.
Feed rate is adjusted by the operator until the
saw is operating efficiently, usually determined
