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.
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.
WARNING:
Failure to turn the saw off, remove the switch key, and unplug the saw could result in accidental starting causing possible serious personal injury.
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.
