Tensioning Blade
Proper blade tension is essential to avoid blade
vibration, twist, or slippage on the wheels. A
correctly tensioned blade provides long blade life,
straight cuts, and efficient cutting.
The three major signs of incorrect blade tension
are: 1) The blade stalls in the cut and slips on the
wheels, 2) the blade frequently breaks, and 3) the
bandsaw does not make straight cuts.
Loosen blade tension when bandsaw is not in
use to prolong blade life.

5.
Check blade placement by sliding fingernail
between end of blade and wheel shoulder.
— If there is just enough space to fit
fingernail, then blade is properly placed.
Proceed to Step 6.
— If there is too little or too much space to
fit fingernail, adjust blade on wheels until
blade placement is correct.
6.
Loosen top blade guide lock handle, adjust
top blade guide as far up as possible, then
tighten top blade guide lock handle to secure
(see Figure 38).
7.
Adjust blade tension handwheel clockwise to
tighten blade or counterclockwise to loosen
blade (see Figure 38).
— Adjust blade tension handwheel until
indicator on belt tension gauge (see
Figure 38) moves to required tension
for blade (about 20,000 PSI for carbon
blades and 30,000–35,000 PSI for bi-metal
blades).
