Alpha HW615/Ambassador C14 Bandsaws: Aligning the Upper Guide and Thrust Bearing Bracket to the Blade

Modified on Thu, 5 Mar at 12:16 PM

Important Safety Precautions

⚠️ CAUTION:
Before performing any maintenance or adjustments:

Ensure the saw is powered OFF.
Unplug the machine from the power source.
Confirm all moving parts have come to a complete stop.
Discharge any stored electrical energy if applicable.

Failure to follow these precautions can result in serious injury or electrical hazards.

Overview

Proper alignment of the blade bearing guides is critical to the safe and efficient operation of your Alpha HW615 or Ambassador C14 band saw. Following the correct procedure will ensure:

Accurate cutting performance
Extended blade life
Reduced risk of blade breakage or machine damage

If the upper guide bearing bracket assembly needs to be realigned to the blade, performing the following steps to realign the rotation and shift of the upper guide bearing bracket.

1. Start by tightening the lock handle for the post:

2. Next, loosen the two set screws on each side of the circular guide bearing bracket:

3. The whole bracket assembly will now be able to pivot. If the bearings are on an angle front to back no matter how the bracket is pivoted, loosen the two screws on the back of the bracket and shift the guide over until the thrust bearing and guide bearings at their widest setting appears centered to the blade.

4. Before fully tightening the two bracket set screws on the sides and the two cap screws at the back, rotate the guide bearing shafts so they evenly pinch the blade tightly maintaining being centered to the blade. Then tighten the bracket screws tight.

5. When done, loosen the lock nuts for the bearing shafts and rotate them outwards from the blade slightly and confirm that the gaps are even front to back on both sides. You should have a setup where the blade is centered to both the thrust and guide bearings and even gaps front to back between the guide bearings and the blade.

6. Perform the bearing roller calibration steps on p.15 (HW615) of the manual or use the video link below to complete the realignment process or refer to the video link.
