Note: Steps 3 and 4 may be unnecessary if you’ve just removed a blade. (If needed, refer back to page 14.)
3. Remove the table alignment pin from the table slot and the red circular insert from the center of the table.
4. 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.
5. Feed the blade into the left blade guard and around the
wheels. Make sure the blade teeth point forward
A and
down B .
With the blade properly installed, proceed to blade tension
adjustments and blade tracking adjustments, as per instruc-
tions on the next few pages.
ADJUSTING BLADE TENSION
Note: To prolong the life of the blade whenever the bandsaw is not in use for prolonged periods (more than 24 hours),
release the blade tension lever to remove tension from the blade, Over time, maintaining tension on a blade that is not
in use will cause the blade to deform, by taking the shape of the wheels at both extremities. This can weaken the blade
and cause premature breakage.

2. With the saw turned off and the tension lever
lowered
, press against the side of the blade to test
the tautness of the blade C . For ideal results with
most blade widths and cutting applications the
blade should flex in no more than 1/4" to 3/8".
3. Make a test cut on a sample piece of wood and if
needed re-adjust the blade tension
B
Do Not Over-Loosen Blade Tension Mechanism! To avoid inadvertently unseating/disconnecting the ten-
sion mechanism, do not loosen the blade tension beyond the range shown on the tension scale. Loosen
the tension gradually, in increments, and retighten the tension lever periodically as you go to verify on the
tension scale and avoid loosening too much.
1. Refering to the blade tension scale A , set the blade
tension to correspond with the width of the blade
installed on your bandsaw. Adjust the blade ten-
sion by lifting the blade tension handle
B , then by
turning it:
- Clockwise to tighten
- Counter-clockwise to loosen the blade tension.
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
This model 90-170B M1 bandsaw is equipped with a blade tension scale, which can be used as a reference for the
ideal setting with various blade widths.
