Blade Guide Adjustment
Proper guide adjust is important to the proper opera-
tion of the bandsaw and will extend the life of the
bandsaw blade.
In general the guide bearings should be close
enough to guide the bandsaw blade to control deflec-
tion during the cut but not tight against the blade.
Positioning the bearings too close against the blade
causes too much friction and can work
-harden the
blade causing premature blade failure.
Upper Blade Guide
The set screws on the back of the upper guide A, B,
and C are used to position the guide assembly along
a shaft.
A moves the entire bearing block and B & C are used
to center the bearing block to the blade.
 First make sure the shaft is flush with the block.
Loosen A make flush and lock.
 To center the thrust bear behind the back of the
blade loosen set screws B & C center bearing
block and tighten.
 To adjust the thrust bearing loosen the cap screw
and move the bearing so it is approximately .015”
away from the back of the blade and tighten.
(Folding a piece of paper 4 times is close).
 Adjust the side bearings by loosening the corre-
sponding cap screws and by moving the adjust-
ment pins (D), to position the bearings
within .004” of the blade and tighten. (Single pa-
per thickness is fairly close).
Lower Blade Guide
The lower blade guide adjustments work in similar
fashion as the upper guide. The block holds the bear-
ing block in place along a shaft.
 The bear block assembly can be adjusted along
the shaft by loosening the set screw G position-
ing and then re-tightening.
 Loosen the set screws E & F. Center the bearing
block to the blade and tighten.
 Adjust the side blade bearings by loosening the
corresponding cap screws and slide the bearings
to within .004” of the blade and tighten. (Single
paper thickness is fairly close).
Make sure the bandsaw is disconnected from the
power source before making any adjustments.
