Do not leave the machine unattended during this
procedure
1. Drawbar removed? Speed control at lowest setting
(counter-clockwise)?
2. Test the spindle motor by setting the motor switch,
Figure 2-7, to Forward and Reverse in turn. Viewed

when Forward is selected.
3. Run the spindle at 60 rpm for a few minutes, then
stop.
4. With the spindle running, check the Emergency Stop
function by pushing rmly on the orange button. This
should immediately stop the motor. (If not, service
attention is required.) Once the E-stop button is
pushed in, it stays in until twisted rmly clockwise.
5. Run the spindle at various speeds up to the maxi-
mum, about 3000 rpm. Check that the lower end of
the spindle remains cool or slightly warm to the touch.
The machine should now be ready for normal opera-
tions.
