Adjusting Spindle Speed - Grizzly G0842 Owner's Manual

Adjusting Spindle
Speed
Spindle speed must be adjusted while lathe
is running. Adjusting spindle speed while
machine is not in operation could result in
permanent damage to the machine, which is
not covered under warranty.
Spindle Speed Range: 600–2400 RPM
users can select one of 10 speeds within this
range by pulling out the spindle speed lever and
moving it right to increase rpM or left to decrease
the rpM (see figure 41).

— When a lot of material must be removed
and a rough finish does not matter, use
low range (lever positioned left of center).
— When making light cuts or when a clean
finish is required, use high range (lever
positioned right of center).
— For general turning operations, or as a
compromise between the two ranges, use
mid range (lever in center position).
refer to the chart in figure 42 to choose the
appropriate rpM for your operation.
