9-4. ADJUSTING UPWARD AND DOWNWARD TRAVEL OF SAW ARM
The downward travel of the saw arm should be adjusted so that when the
saw arm is in the extreme downward position, the teeth of the blade will
not touch the table surface. The stop screw (N) is used to adjust the
distance between blade and table surface. After the distance is adjusted,
tighten lock nut.
The screw (M) is used to adjust the saw arm upward angle, tighten lock
nut.

9-5. ADJUSTING BLADE TENSION AND BLADE TRACKING
To tension the blade, turn the blade tension handle (fig. 1)(A)
clockwise. The scale is graduated to indicate blade tension of
20,000, 30.000 and 35,000 pounds per square inch (psi). For
carbon blades, the blade should be tensioned at 20,000 psi. For bi-
metal blades (similar to the one supplied with the machine), the
blade should be tensioned at 30,000 or 35,000 psi. Always release
blade tension at the end of each working day to prolong blade life.
Make sure the blade is tensioned correctly before checking or
adjusting tracking. The blade is tracking properly when the back of
the blade is just lightly touching the wheel flanges of both wheels
while the machine is running.
9-6. ADJUSTING CUTTING WIDTH
First loosen screw (A) (fig.2). Move the left blade guide bar
to the suitable position. Then tighten screw (A).
