3.Tighten the lock collar and check the track- ing.

For the best performance from your saw, regular- ly maintain proper tracking of the blade.

For Coplanar Tracking, see the ÒWheel AlignmentÓ instructions.

Blade Guides

You must check the upper and lower support bearings and guide blocks each time before start- ing your bandsaw.

Always adjust the assemblies away from the blade before installing a new blade or making blade tracking adjustments. After blade tension and tracking are set correctly, readjust the upper and lower support bearings and guide block assemblies into position. See Figure 18A control locations.

Always disconnect power to the machine when making adjust- ments. Failure to do this may result in serious personal injury.

Support Bearing

Support Bearing

The support bearings back-up the blade during the sawing operation. To adjust the support bearings:

1.Loosen guide blocks and loosen the setscrew that holds the guide block assem- bly to the guide post. Remove the guide block assembly.

2.Loosen the thumbscrew that secures the support bearing shaft and unscrew the adjustment knob that controls the support bearing shaft. See Figures 18A/B for loca- tions.

3.Remove the support bearing shaft from the guide block assembly. Rotate the the shaft so the blade will ride off-center against the support bearing as shown in Figure 18B. Install the shaft, tighten the mounting setscrew and replace the adjustment cap.

4.Turn the adjustment cap so that the upper and lower support bearings are approxi- mately .016" (thickness of a dollar bill x 4) behind the blade. Tighten the thumbscrews.

5.To adjust the lower support bearing, remove the lower guide block assembly by taking out the two setscrews that mount it to the band- saw body. Make the same adjustments described in steps 2-4 and mount the guide block assembly back to the bandsaw body.
