Note: Steps 3 and 4 may be unnecessary if you’ve just removed a blade. (If needed, refer back to the previous page.)
3. Remove the table alignment pin from the table slot and the red circular insert from the center of the table.
4. Remove the right hand side blade guard by loosening
the two Phillips head screws, just enough to slide it out.
5. With the blade perpendicular to the wheels, guide it
through the table slot, then rotate the side of the blade
nearest you back toward the left side of the wheels.
6. Feed the blade into the left blade guard and around
the wheels. Make sure the blade teeth point forward
and down . (See Fig. 25)
With the blade properly installed, proceed to blade tension adjustments and blade tracking adjustments, as per
instructions on the next few pages.
To install a blade:
1. Turn off the bandsaw and unplug the power cord.
Beware of the blade popping open.
Note: You may want to use a thick shop towel to
handle the loose blade or wear a pair of heavy
duty work gloves for the following steps.
2. If you are installing a new blade, carefully remove the
blade from its package. Hold it firmly with one hand as
you remove the twist ties. Slowly separate the coils of
the blade until it unravels into one hoop.

Determining ideal blade tension is somewhat subjective. It is learned through practice and experience and is some-
what dependant on personal preference and individual work habits.
A properly tensioned blade is critical to obtaining maximum performance from any bandsaw. A properly tensioned
blade will last longer and be much less likely to break prematurely. If the blade tension is too loose you will notice
that the blade will have a tendency to drift or slip off-line when cutting and you will have more difficulty controlling
your cuts. A blade that is tensioned too tightly will break prematurely and will be difficult to work with when making
tighter radius cuts.
The following information can be used as a guideline or starting point to assist you in determining ideal blade ten-
sion for your needs:
•
When working with wider blades, re-sawing taller stock, making straight cuts or wide sweeping curves tight-
er blade tensions will provide better results.
•
When working with narrower blades, sawing shorter stock and making tighter curved cuts are best per-
formed using less tension
