Blade Center
Tracking
Blade tracking is affected by the tilt of the upper wheel (known as center tracking) and the align- ment of both wheels (known as coplanar track- ing).
The wheels on this bandsaw were aligned at the factory, so center tracking is the only adjustment that needs to be performed when the saw is new (refer to the Wheel Alignment on Page 49 for detailed instructions on coplanar tracking).
Note: Changes in the blade tension may change the blade tracking. For best performance, regularly check and maintain the proper blade tracking.
To center track the blade:
1.DISCONNECT BANDSAW FROM POWER!
2.Adjust the upper and lower blade guides away from the blade (refer to Adjusting Blade Guide Bearings later in this manual for detailed instructions).
Note: When adjusting the blade tracking, the blade must have a reasonable amount of ten- sion to simulate operating conditions. After the Test Run is successfully completed, you will perform a thorough version of the follow- ing steps to correctly tension the blade.
3.Move the quick release lever up to the verti- cal position (see the following figure), then use the blade tension adjustment knob to bring the red marker to the correct mark on the tension scale for the blade installed.

4.To tension the blade, pull the tension quick release lever down to the horizontal position.
5.Open the upper wheel cover, then spin the upper wheel by hand at least three times and watch how the blade rides on the crown of the wheel. Refer to the figure below for an illustration of this concept.
—If the blade rides on the center of the crown, then the bandsaw is already tracked properly and no additional adjust- ments are needed. Skip to Step 9.
—If the blade does not ride on the center of the crown, then continue with the next step.
