Changing Blade Speed - Grizzly G0948 Owner's Manual

Changing
Blade Speed
The Model G0948 offers blade speeds of 1520
and 2620 FPM. Speed changes are made by re-
positioning the V-belt in different pulley grooves.
Keep in mind, cutting results are not just related
to blade speed. Other factors include the type of
workpiece, the blade being used for the operation,
and the feed rate.
Use the chart below as a general guide for which
blade speeds to use for various operations:
