Tracking The Blade; Adjusting Upper Blade Guide Assembly - Delta 28-190 Instruction Manual

TRACKING THE BLADE

For accurate work and maximum blade life, it is
important that the blade be centered on the upper band
saw wheel. When this adjustment is properly made, the
blade will "track", that is, it will run steady in the same
line. To "track" the blade, proceed as follows:
1. DISCONNECT THE SAW FROM THE POWER
SOURCE.
2. Make sure the correct blade tension is applied to the
saw blade and make sure the blade guides and blade
support bearings are clear of the blade so as not to
interfere with the tracking adjustment.
3. Rotate the upper wheel (A) Fig. 18, slowly by hand to
determine if the blade is riding on the center of the
wheel.
4. If the blade is not riding on the center of the wheel,
loosen wing nut (B) Fig. 19, and while turning the upper
wheel by hand, turn tracking knob (C) slightly clockwise
or counter-clockwise. You will notice that the saw blade
will move to the right or left on the wheel. NEVER RUN
THE SAW TO TRACK THE BLADE.
5. When the blade is tracking properly, tighten wing nut
(B) Fig. 19.
6. Close both upper and lower wheel covers.
ADJUSTING UPPER
