ADJUSTMENTS
ADJUSTING THRUST BEARINGS, BLADE GUIDE SUPPORT, AND BLADE GUIDES
See Figures 20 - 22.
The upper and lower blade guides and thrust bearings support the band saw blade during cutting operations. The adjustment of the guides and bearings should be checked whenever a different blade is installed.
To Adjust Thrust Bearings:
The thrust bearings support the back edge of the blade during cutting. The blade should not contact the thrust bearings when you stop cutting. It is important that both upper and lower thrust bearings be adjusted equally.
NOTE: The thrust bearing screw is the upper cap screw located on the right side of the blade guide assembly. It is the lower cap screw on the right side of the saw housing below the saw table for the lower bearing. See Figures 20
and 21.
Remove the blade guard by loosening the two phillips screws.
Turn the lock knob counterclockwise to unlock the blade guide assembly. Turning the blade guide knob clockwise, raise the blade guide assembly as far as it will go. Turn the lock knob clockwise to retighten.
Adjust the thrust bearings first. Using the 4 mm hex key, loosen the thrust bearing screw.
Move the thrust bearing to within 1/64 in. (0.4 mm) of the blade. Tighten the thrust bearing screw securely. Repeat this procedure on the lower thrust bearing located below the saw table.
Replace the blade guard if no additional adjustments are to be made.
To Adjust Blade Guide Support:
NOTE: The lower blade guide support screw is the top screw located on the right of the saw housing under the table. See
Figure 21.
WARNING:
Never operate saw without blade guard secured in place. To do so could result in possible serious personal injury.
