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.
