Adjusting the Blade Guides
Upper Guides: To adjust the upper blade guides, first
position the roller guides relative to the blade by
loosening the locking hex screw (A--Fig. 9) and moving
the guide carrier until the roller guides are approx. 1/16”
behind the gullets of the blade. Next set the roller guides
to within 1/32” of the blade by releasing the screw (B--Fig.
9) on each side of the blade. Do not set the guides too
close, as this will adversely affect the life of the blade.
Finally, adjust the thrust bearing to be just clear of the
back of the blade by unlocking the hex nut (C--Fig. 9).
When the correct adjustment is reached, lock the thrust
bearing in position with the hex nut (A--Fig. 9).
Lower Guides: To adjust the lower blade guides, first
loosen the hex nut (A--Fig. 10) then move the guide
carrier casting to allow the front to be approx. 1/16”
behind the gullets of the Bandsaw blade and tighten the
hex nut (A--Fig. 10). Next set the roller guides to within 1/
32” of the blade by releasing the screw (B--Fig. 10) on
each side of the blade. Adjust the thrust bearing to be just
clear of the back of the blade by unlocking the hex nut (C--
Fig. 10), and turning adjusting knob (D--Fig. 10). Finally,
tighten hex nut (C--Fig. 10).
Make sure doors are closed, turn the bandsaw on and
inspect that the upper, lower and thrust bearings are not
turning. All bearings should not turn unless pressure from
workpiece is applied to the blade. If bearings are turning
under no pressure, repeat steps to adjust the blade
guides.
Adjusting the Rip Fence Guide Scale
Slide the rip fence against the blade along the rail and
loosen the indicator screw (A--Fig. 11). Then move the
scale (B--Fig. 11) sideways and align the zero on the
scale with the line on the magnifying window (C--Fig. 11).
Retighten the indicator screw when the adjustment is
correct.
Adjusting the Cutting Height
Loosen the guidepost lock knob (Fig. 12) and turn the
guidepost handwheel (Fig. 12) to raise or lower the
guide post/upper blade guide assembly to the desired
height. Then tighten the guidepost lock knob. Note: The
bottom edge of the guide bearings should be
approximately 1/4”above the top surface of the work
piece.
