SECTION 5: ADJUSTMENTS

Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back.

Disconnect power to the machine when perform- ing any maintenance or assembly. Failure to do this may result in serious personal injury.

Wear safety glasses dur- ing the entire adjust- ments process. Failure to comply may result in serious personal injury.

NOTICE

Read through the entire manual before starting the table saw.

Blade Tension

To adjust the tension:

1.Loosen the upper and lower guide blocks and lower the upper guide block down to the table. With moderate tension already on the blade, turn the bandsaw ON.

2.Release the tension one quarter of a turn at a time. Do this very slowly. When you see the bandsaw blade start to flutter, stop decreasing the tension.

3.Now, slowly increase the tension until the blade stops fluttering. Tighten the tension one quarter of a turn.

G1073/G1073Z 16'' Bandsaw

If the tension seems correct, turn the bandsaw OFF and make the other adjustments, and test run. If the blade does not cut properly, the tension may be incorrect. Readjust the tension. New blades often stretch with use. However, it helps to always remove the tension from the blade when not in use.

Blade Tracking

There are two ways to track a bandsaw blade: Center Tracking and Coplanar Tracking. Center Tracking is the fastest and easiest, but not the most precise.

Center Tracking:

1.Disconnect the bandsaw from the power source and adjust the upper and lower guide assemblies away from the blade. Refer to Page 18 for adjustment details.

2.Loosen the lock collar on the tracking control knob shown in Figure 17. Turn the tracking control knob clockwise/counterclockwise while turning the upper wheel by hand until the blade stays centered on the rubber tire.
