Adjusting Blade

Guides & Supports

The blade guides and supports provide side-to- side and rear support to keep the blade straight while cutting. These devices have tungsten steel facing to reduce wear on the surfaces. Properly adjusted blade guides and supports are essential to making accurate cuts.

To properly adjust the upper and lower blade guides and supports:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the bandsaw blade is properly ten- sioned (refer to Page 25) and the blade post is in the correct position and locked.

3.Use a 6mm hex wrench to loosen the cap screws that secure the blade guide bracket and blade support (see Figures 20–21).

The bandsaw blade is sharp and can easily cut your hand or fingers. Always disconnect the power and wear heavy leather gloves when making adjustments to or near the blade.

NOTICE

The blade guides must be adjusted far enough back so that they are behind the tooth gullets when the blade is deflected back against the blade support during oper- ation. Otherwise, the teeth will be damaged as they come in contact with the blade guides.
