12. BLADE TRACK ADJUSTMENT
(1). Open the blade guard.
(2). Remove the blade guide assemblies (top and bottom)
(3). Loosen the hex head screw in the tilting machanism to a point where it is loose but snug.
(4). With the machine running, adjust both the set crew and blade tension knob simultaneously to
keep constant tension on the blade. The set screw and blade tension knob are always turned in
opposite directions, ie, when one is turned clockwise the other is turned counterclockwise.
The blade is tracking properly when the back side just touches the shoulder of pulley or a
slight gap appears near the center line of the pulley. Care should be taken not to over-tighten
the saw blade since this will give a false adjustment and limit life of the blade.
(5). Tighten the hex head screw in tilting mechanism. IMPORTANT: Sometimes in trying to
make this critical adjustment it is possible to cause the basic setting to be misaligned. Should
this occur, proceed as follows:
a. Loosen the set screw and back it out as far as it can go and still remain in the threaded hole.
b. Turn the hex head screw clockwise until it stops (do not tighten).
c. Turn the set screw clockwise until it bottoms, then continue for half a turn and check the
tracking by turning on the machine.
d. If further adjustment is required, go back to step 4.
(6). Turn off power to the machine.
(7). Replace the clade guide assemblies--it may be necessary to loosen the blade tension alightly.
(8). Adjust the vertical position of blade guide bearing assemblies so that the back side of the
blade just touches the ball bearing.
(9). Make a final run to check tracking. It required, touch up adjustment (See stop 4)
(10). Replace the blade guards.
Hydraulic Feed Adjustment
(1) To adjust the feeding rate when in cutting, Turn the volume valve (A) clockwise for faster
feeding, counterclockwise for slower feeding.
(2) When cutting feed is too fast, raise the saw arm, then slower the feed rate to prevent blade
damage.
BLADE SPEEDS FOR GEAR BOX:
When using your Band saw always change the blade speed to best suit the material being
cut the material Cutting Sheet givers suggested settings for several materials.
