— If the deflection is correct and the V-belts
are in good condition, no further action is

" or the V-belts need to be replaced, then
continue to Step 5.

6. If it is necessary to replace the V-belts, slide
the motor toward the wheel pulley to relieve
the tension, then replace the V-belts with a
new matched set.
7. Position the motor to adjust the V-belt tension
until they have the correct deflection, then re-
tighten the hex bolts.
When the wheels are coplanar (in the same
plane), the bandsaw cuts straighter, with much
less vibration, heat, and blade wear because the
blade is continuously balanced on the wheels.
