Understanding Thread & Feed Rate Chart
Figure 45 shows the con
fi
gurations of gearbox levers that are required to set the available feed rates.
This same chart can also be found on the machine.

Positioning Gearbox
Levers
To cut a particular thread or establish a particular feed
rate, you may need to
fi
rst swap the gearbox drive
gear, depending on where it is currently set.
Once you have con
fi
rmed that the end gear is set up
properly, you can then move the gearbox levers to
the required positions. The arrows going from Figure
50 to Figure 51 show which gearbox levers must be
moved to achieve an example feed rate.
