Blade Speed - Grizzly G0640X Owner's Manual

Blade Speed

This bandsaw features a variable blade speed
between 100–3600 FPM. There are two blade
speed ranges. A fast range for wood cutting and
a slow range for metal cutting.
The variable speed dial controls the blade speed
within each range. The position of the V-belts
behind the lower wheel cover control which speed
range is activated. A disc with a spiral shape is
located near the motor as a reminder to the oper-
ator which blade speed range is engaged. The
disc spins when the metal cutting speed range is
engaged.
The V-belt tension is controlled in two ways,
depending on which position it is in. When in the
"wood" position, the V-belt tension is controlled
by the position of the motor, which pivots to ten-
sion/loosen the belt.
At "metal" position, the V-belt tension is controlled
by the hand crank located between the dust
ports.

Note: If one belt is used more than the other
belt, it will stretch slightly under normal condi-
tions. This means that one belt may be looser
than then other when both belts are installed.
This is normal. Overtightening one belt in
attempt to tighten the other will decrease the
lifespan of the bearings in the pulleys.
