Drill Bit Changes
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 a
new bit.
3. Install the bit so the chuck jaws will grab as
much of the bit shank as possible. Do not
allow the chuck to grab the fluted body of the
drill bit. Make sure small drill bits do not get
trapped between the edges of two jaws.
4. Tighten the chuck with the chuck key using
any of the three key end locations.
5. Remove the chuck key and reconnect the
power source.
6. Reverse steps to remove the drill bit.
Once assembly is complete and adjustments are
done to your satisfaction, you are ready to test run
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 paddle switch, just in case
there’s a problem. The drill press should run
smoothly, with little or no vibration or rubbing nois-
es. Strange or unnatural noises should be investi-
gated and corrected before operating the
machine further.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.
Disconnect power to the
machine when perform-
ing any maintenance,
assembly or adjust-
ments. Failure to do this
may result in serious
personal injury.
Wear safety glasses
during the entire opera-
tion process. Failure to
comply may result in
serious personal injury.
Keep loose clothing
rolled up and out of the
way of machinery and
keep hair pulled back.
