BAND SAW ALIGNMENT (continued)
back. Adjust the guide bar up and down and note whether the backup bearing and guide bar are parallel to the
back of the band. If it is not, the bracket will have to be adjusted with the jackscrews to bring the post into line with
the band. Check also on the side parallelism of the side of the guide bar to the band. With one of the inserts
slightly clearing the band and the other well clear of the band, raise the guide post up and down to see if it moves
parallel with the band. If it is not parallel, the bracket must be pivoted into alignment using the bottom jackscrews.
Use care in adjusting all jackscrews so that proper locations are maintained and the wheels remain parallel. Note
the back of the band should lightly contact the backup bearing over it's full travel.
7. the transmission and upper wheel bracket in place. Note prior to locking the extreme right hand screw of the
upper wheel bracket, adjust the two set screws above and below it to be in light contact with the backup plate.
8. the four mounting screws holding the trunnion to the frame cross member. Reinstall the lower guide and table.
Locate the trunnion so that the band overlaps the backup by approximately .093" and is centered in the insert slot.
Using a combination square, check the squareness of the table to the back of the guide bar and square the table
to the back of the guide post using the jackscrews provided in the trunnion support bracket. Position the trunnion
so that there is good contact between the back of the band and the backup bearing. Lock the trunnion bracket to
the cross member.
9. the combination square on the table and against the side of the guide post, using the table stop at the left hand
side of the table, square the table sidewise to the post. Lock the stop screw with the jam nut provided.
10. Tilt the table at 450 to the right and check to be sure the band clears the insert. If it does not clear, loosen the four
screws that mount the table to the trunnion and readjust the table. Re-tighten the mounting screws and recheck
both the 00 and 450 points for band clearance.
