of the safety instructions starting on Page 6
of this manual, and verify the machine is set
up properly.
2. Do NOT install the chuck before completing
the Test Run.

4. Make sure all tools and objects used dur-
ing the setup are cleared away from the
machine.

6. Use the speed control to reduce the speed
to 300 RPM and let the drill press run for a
minimum of 10 minutes.
7. Listen and watch for abnormal noises or
vibrations. The machine should run smooth-
ly.
— Unusual noises or vibrations should be
investigated and corrected before operat-
ing the machine further. Always disconnect
