9. Bandsaw Blade Set Up
CAUTION!
Before carrying out any adjustments or
maintenance ensure that the machine is isolated and
disconnected from the electricity supply.
Tensioning the Blade
The blade tensioning knob (Fig. 9.1, A) should be used to
increase or decrease tension.
The only accurate way to check a blade is with a tension
meter, these are very expensive so most users may need
another method. We suggest testing the tension by the
amount the blade will deflect sideways. First set the guides
to 6” above the table, ensuring the saw is turned off push
the blade sideways with a reasonable amount of pressure
using the index finger. When pushing with the index finger
a correctly tensioned blade should not move more than a
1/4” sideways (See Fig. 9.2)
However perhaps the most tried & tested way of blade
tensioning is simply: if the bandsaw is cutting accurately
then the blade is tensioned correctly, if the blade tends to
wander & an accurate cut cannot be achieved then the
blade tension needs adjusting.
If the machine is to stand idle for a period it is good
practice to slacken tension & re-tension when next using.
