-20- 24" & 27" Resaw Bandsaws
Blade Tension
Proper blade tension is essential to any cutting
operation on the bandsaw. Any time you change
blades or remove a blade, you must re-adjust the
tension.
To adjust the tension:
1. Loosen the upper and lower guide blocks.
Tighten them down and away from the blade
BEFORE turning
ON .
2. Lower the upper guide block assembly down
to the table and tighten.
3. With moderate tension already on the blade,
turn the bandsaw
ON .
4. If you see the blade start to flutter, increase
the tension until the blade stops fluttering,
then tighten the tension handle an additional
half turn.
If the blade does not flutter, decrease the
tension until it begins to flutter, then tighten
just to the point that it stops fluttering. Now
tighten the tension handle an additional half
turn.
5. Turn the bandsaw OFF and make the other
adjustments in this section. Also, check the
tracking and blade guides to make sure that
they did not change after tensioning the
blade.
If the blade does not cut properly, the tension
may be incorrect. Re-adjust the tension.
After setting the tension, make a note of what the
tension gauge reads. Use this to go back to your
tension setting during later tensioning and reten-
sioning with that particular blade.
Keep in mind that blades will last longer if you
release the tension after every use. Also, new
blades will often stretch with use. A tension that
worked well when a blade was new may not work
as well after the blade has been used.
Turn on the power supply at the main panel. Push
the
START button to turn on the bandsaw. Make
sure that your hand is poised over the switch in
case there is a problem. The bandsaw should run
smoothly with little or no vibration or rubbing nois-
es. If strange or unnatural noises are immediate-
ly apparent, press the
STOP button. Investigate
and correct before operating the machine further.
If you cannot easily locate the source of an
unusual noise or vibration, feel free to contact our
service department for help.
Test Run
The rest of the adjustments in this section
require you to start the bandsaw. Before
starting the bandsaw, make sure you have
performed the preceding assembly and
adjustment instructions, and you have read
through the rest of the manual and are
familiar with the various functions and safe-
ty issues associated with this machine.
Failure to follow this warning may result in
serious personal injury or even death!
