Positioning Guide Post

The guide post assembly is used for two purposes: 1) To properly position the blade guard to protect the operator from the exposed blade between the workpiece and the upper wheel housing, and 2) to position the upper blade guides close to the workpiece for maximum blade support.

To properly position the guide post:

1.DISCONNECT BANDSAW FROM POWER!

2.Hold the guide post knob with one hand and loosen the guide post lock knob with the other (Figure 17).

3.Position the bottom of the upper blade guides approximately 1⁄4" above the workpiece, then re-tighten the lock knob to secure the setting.

All saw blades are dangerous and may cause personal injury. To reduce the risk of being injured, wear leather gloves when handling saw blades.

Adjusting Blade

Guides

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

If the blade guides rub the blade at either the top or bottom of the blade, follow the guide post alignment procedure on Page 36 for adjusting the guide post parallel with the blade.

To properly adjust the upper and lower blade guides:

1.DISCONNECT BANDSAW FROM POWER!

2.Make sure the bandsaw blade is properly tensioned (Page 23) and the guide post is locked.

3.Use a Phillips head screwdriver to remove the flange screws that secure the lower blade guide cover, then remove the cover to access the cap screws in the next step.

4.Use a 5mm hex wrench to loosen the cap screws that secure the blade guide bracket and blade support (see Figures 18–19).
