Belt Alignment

If the drive belt is not aligned properly, it can be aligned with one or more of the four set screws located behind the steel plate. Figure 25 shows two of the set screws.

1.Loosen the four hex nuts (A, Figure 23)

2.Rotate clockwise one of the set screws (Figure

25)with a 4mm hex wrench, to push out the motor plate at that point. This will shift slightly the angle of the motor. Use whichever set screw is most effective in adjusting the angle of the motor until the drive belt is aligned.

3.Confirm the alignment of the drive belt by placing a straight edge against the faces of both pulleys, as shown in Figure 26. If the straight edge lies flush against both pulleys, then the pulleys and belt are aligned.

4.Re-tighten the four hex nuts (A, Figure 23).

Blade Speed Adjustment

The bandsaw will operate at 2,000 or 4,000 SFPM (surface feet per minute). Figure 27 shows the appropriate belt position to achieve each speed.

To change the speed:

1.Disconnect machine from power source.

2.Loosen the four hex nuts (A, Figure 23) and rotate the tension screw (B, Figure 23) counterclockwise to release tension on the belt.

3.Slide the belt onto the appropriate set of pulleys (Figure 27). Make sure the belt is aligned properly.

4.Re-tension the belt (see under “Belt Tension”) and securely tighten all four hex nuts on the motor plate (A, Figure 23).

Operating Controls

The START (green) and STOP (red) control buttons are mounted to the column (Figure 28).

After the STOP button has been pushed, it remains engaged. Rotate the STOP button clockwise to release it. The Band Saw can now be restarted with the START button.

After the machine is shut off, allow the wheels and blade to come to a complete stop before opening the doors, making adjustments, or leaving the area.
