Grizzly G0659 owner manual Blade Tracking, Upper Blade Guide Assembly Adjustment

8.While still holding the blade guide assembly in position as described in Step 6, slide the blade guide assembly in or out as necessary so the roller guide flange is directly behind, but not touching the back of the blade, then tighten set screw B (Figure 40).

Upper Blade Guide Assembly Adjustment

Adjusting the upper blade guide assembly follows the same procedure as adjusting the lower blade guide assembly. The additional consideration is that the upper blade guide assembly must also hold the blade square to the table.

To position the upper blade guide assembly:

1.DISCONNECT BANDSAW FROM POWER.

2.Loosen set screws A, B, and C on the upper blade guide assembly.

3.Wearing gloves, hold the blade square to the table. Rotate the eccentric shaft (Figure 39) so the blade guide assembly is centered over the blade, as shown in Figure 41, then tighten the cap screw located in the bottom of the guide post.

Blade Tracking

"Blade Tracking" refers to how the blade rides on the wheels. When tracking correctly, the blade rides just next to, but not touching the wheel flange. Blade tracking is primarily controlled by adjusting the upper wheel tilt.

Another way to track the blade is known as "Coplanar Tracking." Coplanar tracking involves aligning the wheels so they are parallel and aligned (see Wheel Alignment on Page 40). When wheels are coplanar, vibration and heat are reduced during operation.

Blade tracking on the Model G0659 must be adjusted with the saw running. To reduce the risk of serious injury, keep hands clear from all moving parts and touch only the parts indicated in the following instructions. In addition, wear eye protection whenever the machine is running.

To adjust the blade tracking:

1.Open the upper wheel cover and familiarize yourself with the wheel, the wheel flange, the blade, and the relationship between the blade and wheel flange (Figure 42).
