Refit all the guards and close the doors. Replace the table insert and check that the blade
moves freely through the table insert. Check that all wrenches and loose parts are removed
from the machine.
Plug the machine into the power. Turn the machine on for a second and switch off. Watch
how the blade runs. If the blade tracks well, then run the machine at full power. If the blade
tracking needs adjustment, repeat adjustment.
Method 2.
Tension the blade as described in method 1.
Close all the doors and ensure that all the guards are fitted.
Start the bandsaw and look at the blade from the front of the machine. Start to distension
the blade very slowly until the blade starts to flutter (wobble from side to side). Then start to
tension the blade until the blade stops fluttering and is running true. Increase the tension on
the blade by one complete turn on the tension handle. You may find that each size and type
of blade will need more or less additional tension. For example, a 1/16" blade will need less
additional tension than a 1 1/2" blade. Again, experience is the key, and with a little
practice, it will become second nature.
The key to all tensioning is to get the blade to cut straight and true with the minimum
amount of tension. The less tension you put on the blade, the longer the blade and the
machine will last.
Note. The upper flywheel has a spring that is used to keep a constant pressure on the
blade during use. As the blade cuts, heat is generated, which causes the blade length to
expand. The spring compensates for the change in length, and you must never bottom out
the spring while tensioning the blade.
Note. If you are not using the bandsaw for extended periods of time (overnight), remove the
tension on the blade. This will increase the life of your blade and the machine. If tension is
left on the machine, flats or grooves can be formed in the rubber of the wheels, which will
detract from the performance of the machine and in extreme cases cause vibration.
Removing the tension will greatly enhance the life of the machine, bearings and tires.
Label the machine “de-tensioned.” On the label mark the number of turns that you de-
tensioned; this way you will know how many turns that you have to put back on to have your
blade correctly tensioned.
Removing the blade from the bandsaw
1.
Disconnect the power to the bandsaw.
2. Remove the table split clamp that aligns the two table halves.
3. Remove all the guards.
4. Remove the table insert.
5. Remove the tension on the upper flywheel.
6. Open the doors and remove the blade from the wheels (use gloves and eye protection)
and gently slide the blade through the table slot.
