Blade Replacement

1.Disconnect machine from power source.

2.Raise the bow to vertical position.

3.Loosen the handle (A, Figure 10) and lower the blade guide and front cover (Figure 12) as far as possible.

4.Remove the back blade cover by unscrewing the knobs.

5.Release the blade tension by turning the blade tension knob (Figure 10) counter- clockwise.

6.Extract the blade from the guides and then remove it from around the wheels. (Wear gloves when handling blades to prevent injury.)

7.Inspect the new blade for flaws (cracks, broken teeth, bending) before installing. The blade should be sharp and have a proper set. Do not use a faulty saw blade.

8.Install the new blade through the guides and around the wheels, making sure the teeth are pointing in the proper cutting direction. See Figure 13.

9.The blade should be tensioned and tracked properly before proceeding. See “Blade Tension” and “Blade Tracking” above.

10.Install the back blade cover and re-connect band saw to power source.

11.The new blade must now be “run in.” A carefully run-in blade lasts longer and gives better performance. Let the blade run idle for about two minutes, then perform two or three cuts, preferably on a solid workpiece of .40 to .50 millimeter diameter. Use very light pressure on the blade, gradually increasing pressure with each cut. See under “Operation” for cutting procedures.

Vise Adjustment

Place the workpiece against the fixed jaw, and rotate the handle (Figure 14) clockwise to move the adjustable jaw against the workpiece.

The vise should be tight enough that round stock will not roll. For short workpieces, make sure enough of the workpiece is gripped within the vise to ensure a stable cut. For very long workpieces, use table extensions, roller stands, etc. to help support them.
