 14" Steel Frame Band Saw features two 

upper and lower side bearings and two upper and 

lower rear bearings that can be adjusted in order to 

ensure straight and consistent cuts. It is recommended 

that you periodically check the position of all bearings 

and adjust if necessary.

The upper and lower side bearings (A) should be 

positioned so that there is approximately 1/64" gap on 

either side of the blade. To adjust the position of the 

bearings, side-to-side, do the following:

See “Adjust Blade Tracking" in the Assembly section of 

this manual on page 10.

•  Use a 3MM Allen wrench to loosen the bearing 

screws (B).

•  Reposition the bearings and tighten the bearing the 

screws.

The upper and lower side bearings also adjust back 

and forth and should be positioned so that the front 

edge of the bearings is just behind the blade gullet. To 

adjust the position of the bearings, front-to-back, do 

the following:

•  Use a 13MM open wrench to loosen the top retaining 

nut and a 10MM open wrench to loosen the bottom 

retaining nut. (The bottom retaining nut can be made 

more accessible by tilting the table slightly.)

•  With the retaining nut loosened, both upper side 

bearings or both lower side bearings will move back 

and forth as a unitPosition them so that the front edge 

of the bearings are just behind the blade gullet. 

•  Re-tighten the retaining nuts. 

NOTE: The upper and lower side bearings must both be 

set in place prior to adjusting the upper and lower rear 

bearings.
The upper and lower rear bearings should be 

positioned so that they nearly touch the blade. 

•  To adjust, use a 3MM Allen wrench to loosen the 

bearing screws.

•  Reposition the bearings and tighten the bearing the 

screws.
