Vertical Tilting Band Saw
3. Hold the saw head in this position and slide the forward
stop back until it firmly contacts the contact block.
4. During normal cutting, when the contact block (O, Fig. 14)
contacts the forward stop (Q, Fig. 14), the cutting head
will automatically stop its forward movement, the blade
will shut off, and the saw head will retract to the start
position.
5. The retract stop should be adjusted so that the saw head
stops at a position that has the blade retracted out of the
cut area and before it reaches the full retracted physical
limits.
10.6 Blade Speed Adjustment
1. Always set the feed force to “0” before adjusting the blade
speed.
2. Push the START button on the control panel.
3. If the carriage still moves forward, adjust the feed
force knob counterclockwise (CCW) until it remains
stationary.
4. Push the STOP button. You are now ready to adjust the
blade speed.
5. The blade speed readout on the control panel displays
the blade speed in surface feet per minute. Choice of
blade speed depends on the type and thickness of metal
being cut. Reference Table 1 for the recommended blade
speeds.

To adjust:
1. Loosen the forward travel adjustment handle (Q, Fig. 14)
and slide the adjustment block forward to allow the saw
head to travel forward to simulate the complete cut plus
1/8" - 1/4".
2. Using the manual saw head feed handwheel, move the
saw head forward until the teeth of the blade are forward
far enough to have cut the material plus
1/8" - 1/4". This
will ensure that the material is cut complete.
6. Push the START button on the control panel. Twist the
blade speed control knob clockwise (CW) to increase the
blade speed, counterclockwise (CCW) to reduce blade
speed.
7. Once the proper blade speed is obtained, push the STOP
button on the control panel. Both blade speed and feed
force may be adjusted as necessary while the blade is
cutting.

Twist the feed force knob to increase or decrease the feed
force setting.
10.8 Upper Blade Guide Adjustment
The upper blade guide assembly should be adjusted down
as close to the workpiece as possible without interfering
with the workpiece or vice clamps.
1. To adjust the arm up or down, grasp the handwheel of the
upper blade guide.
2. Loosen the locking handle (R, Fig. 15) and rotate the
handwheel (S, Fig. 15) to lift or lower the guide to the
desired height.
3. Hold the guide in this position and tighten the locking
handle (R, Fig. 15).
