ADJUSTING THRUST BEARINGS, BLADE
GUIDE SUPPORT, AND BLADE GUIDES
See Figures 14 - 16.
WARNING:
Never operate saw without blade guard
secured in place. To do so could result in possible
serious personal injury.
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.
n Remove the blade guard by loosening the two set
screws with the 4 mm hex key.
n Turn the lock lever counterclockwise to unlock the
blade guide assembly. Turning the blade guide knob
(clockwise raises the blade guide assembly, counter-
clockwise lowers it), position the blade guide assembly
about halfway between the saw table and saw housing.
Retighten the lock lever.
