Blade Guides
(G0613)
The blade guides have a basic factory adjust- ment, but due to shipping and storage we recom- mend that you readjust the blade guides yourself to ensure the cuts will to be your standards.
CUTTING HAZARD! Blades are sharp! Put on heavy leather gloves when handling a blade or making adjustments near a blade or cutter!
To adjust the blade guides:
1.Make sure the blade is oiled, tensioned, and tracking correctly.
2.DISCONNECT THE BANDSAW FROM POWER!
3.Raise and lock the bow in place and slide the guides together as close as you can and lock into place.
4.Loosen the two cap screws and the blade guide guard shown in Figure 39.

5.Loosen the cap screws (Figure 41), and adjust the blade guide housing so the back of the blade slightly touches the bearing and the guide housing is not tilted.
6.Tighten the cap screws.
Note: To access the cap screws on the other blade guide, you will have to remove the two Phillips head screws (Figure 40) and move the limit switch and its bracket out of the way.

7.Loosen the 14mm jam nuts and rotate the 7mm hex on top of the bearing eccentrics (Figure 41), and adjust the bearings against the side of the blade.
Tip: There should be no gap between the blade and the bearings. To set this clearance to zero without fighting the twist of the blade, remove the blade guide assemblies, set this clearance to the blade thickness, then rein- stall the blade guide assemblies.
