9-4.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.

9-7.BLADE AND COOLING SYSTEM
The use of proper cutting fluid is essential to obtain maximum efficiency
from a band saw blade. The main cause of tooth failure is excessive heat
build-up. This is the reason that cutting fluid is necessary for long blade
life and high cutting rates. cutting area and blade wheels should be kept
clean at all time.
The rate of coolant flow is controlled by the stop valve lever (A) (fig. 4),
which directs the coolant onto the blade. The lever (A) is shown in the
off position.
Always keep the floor dry to prevent slip or any accident.
