N O T I C E
Never shift the gears of the machine while the machine is in operation and make sure
that both the shift lever tapping (lock nut) and the engaging lever cross feed -
longitudinal feed are disengaged before putting the machine into operation!
Otherwise the carriage may be pushed forward into the chuck or tailstock and cause
serious damage.

Before starting the machine, make sure that you have followed all assembly and
adjustment instructions, that you have read the instructions and that you are familiar
with the various functions and safety features of this machine. Disregarding this
warning may result in serious injury or even death!
After assembly is complete, test the machine to ensure that it is functioning properly and ready
for regular operation. This is done without a clamped workpiece. Perform the test as described
below.
