DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
To test run machine:
1. Clear all setup tools away from machine.
2. Connect machine to power supply.
3. Turn machine ON, verify motor operation,
then turn machine OFF.
The motor should run smoothly and without
problems or unusual noises.
4. Remove key, as shown in Figure 23.

Tensioning Blade

A properly tensioned blade is essential for mak-
ing accurate cuts, maximizing the blade life, and
making other bandsaw adjustments. However, a
properly tensioned blade will not compensate for
cutting problems caused by excessive feed rate,
hardness variations between workpieces, and
improper blade selection.
Optimal cutting results for any type of workpiece
are achieved through a combination of correct
blade selection, proper blade tension, properly
adjusted blade guides and other bandsaw compo-
nents, and using an appropriate feed rate.
Improper blade tension is unsafe, produces inac-
curate and inconsistent results, and introduces
unnecessary wear on bandsaw components.
Over-tensioning the blade increases the chance
of the blade breaking or wheel misalignment.
Under-tensioned blades wander excessively
while cutting and will not track properly during
operation.
The method used to tension the blade is often
a matter of preference. This manual describes
two methods: the flutter method and the deflec-
tion method. Either method will help you properly
tension the blade. Experience and personal pref-
erence will help you decide which method you
prefer.
Note: Tensioning the blade before the Test Run
was an approximate tension. The following proce-
dures fine-tune the blade tension.
