Drill Changes
To insert or change a bit, care must be taken to
secure the bit firmly in place. When changing bits,
proceed as follows:
1. Disconnect the machine from the power
source.
2. Open the chuck wide enough to accept the
bit.
3. Install the bit so the chuck jaws will grab the
major portion of the bit shank. Do not allow
the chuck to grab the fluted body of the drill
bit.
4. Tighten the chuck with the chuck key using all
three key locations.
5. Remove the chuck key and reconnect to the
power source.
6. Reverse steps to remove drill bit.
SECTION 6: OPERATIONS
Once the assembly is complete and the adjust-
ments are done to your satisfaction, you are
ready to test the machine.
Turn on the power supply at the main panel.
Press the START button. Make sure that your fin-
ger is poised on the STOP button, just in case
there’s a problem. The drill press should run
smoothly, with little or no vibration or rubbing
noises. Strange or unnatural noises should be
investigated and corrected before operating the
machine further.
WARNING: DO NOT attempt to investigate or
adjust the machine while it is running. Wait until
the machine is turned off, unplugged and all
working parts have come to a rest before you do
anything!
