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.25) and
moving the guide carrier until the roller guides are
approximately 1/16” behind the gullets of the Bandsaw
blade and tighten the hex nut (A-Fig.25). Next set the
roller guides to within 1/32” of the blade by releasing
the screw (B-Fig.25) 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.25). When the correct adjustment is
reached, lock the thrust bearing in position with the hex
nut (C-Fig.25).
Lower Guides: To adjust the lower blade guides, first
loosen the hex nut (A-Fig.26) then move the guide
carrier casting to allow the front to be approximately
1/16” behind the gullets of the Bandsaw blade and
tighten the hex nut (A-Fig.26). Next set the roller guides
to within 1/32” of the blade by releasing the screw
(B-Fig.26) 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.26), and turning adjusting
knob (D-Fig.26). Finally, tighten hex nut (C-Fig.26).
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 Cutting Height
Loosen the guidepost lock knob (A-Fig.27) and turn the
guidepost handwheel (B-Fig.27) 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. (Fig.28)
