fasteners.

To adjust the Model G8146Z upper wheel:

1.Complete all steps in the Checking Wheel Coplanarity subsection on Page 43.

2.Use a 17mm wrench to loosen the locking hex bolts and a 12 mm wrench to loosen the jam nuts on the upper wheel (see Figure 52).

Note: Threading an adjusting hex bolt in will force that part of the wheel forward. Conversely, threading an adjusting hex bolt out will pull that wheel section to the rear of the machine when the locking hex bolt is re- tightened.

3.Re-tighten the locking hex bolts and jam nuts to secure the settings of the adjusting hex bolts.

4.Re-check the wheels for alignment and repeat the steps above if necessary.

5.Re-install the table and check its alignment with the blade.

Aligning Table To

Blade

To ensure the angle accuracy of the cut, the table must be 90° to the blade from front-to-back and side-to-side. If the table is not square to the blade, it needs to be adjusted.

To adjust the table square to the blade:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the wheels are coplanar (Page 43) and the blade is properly tensioned (Page 29).

3.Set the angle of the table to "0".

4.Use a square to check table alignment with the blade, as shown in Figure 53.
