do not force tool. It will do the job better and more safely at the rate for which it
was intended. Do not use inappropriate attachments in an attempt to exceed the tool
capacity.
use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this tool
was designed. Do not modify this tool and do not use this tool for a purpose for which
it was not intended.
7.
8.
dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear restrictive hair covering to contain long hair.
use eye and ear protection. Always wear ANSI approved impact safety goggles.
Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI
approved dust mask or respirator when working around metal, wood, and chemical
dusts and mists.
9.
do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by an authorized technician.
The handles must be kept clean, dry, and free from oil and grease at all times.
11. disconnect power. Unplug when not in use.
12. remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.
13. avoid unintentional starting. Be sure the switch is in the Off position when not in
use and before plugging in.
14. stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. take caution as some woods contain preservatives such as copper chromium
arsenate (cca) which can be toxic. When cutting these materials extra care should
be taken to avoid inhalation and minimize skin contact.
16. check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified technician.
Do not use the tool if any switch does not turn On and Off properly.
17. guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
18. replacement parts and accessories. When servicing, use only identical

replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.
19. do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
20. use proper size and type extension cord. If an extension cord is required, it must
be of the proper size and type to supply the correct current to the tool without heating
up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the tool. This tool requires use of an extension cord of 0 to 12 amps
capability (up to 50 feet), with wire size rated at 16 aWg. Longer extension cords
require larger size wire (smaller AWG number). If you are using the tool outdoors, use
an extension cord rated for outdoor use. (Signified by “WA” on the jacket).
21. secure Workpiece. Use clamps or a vise to hold workpiece, if possible. Never hold
workpiece with your hands.
22. never leave drill press running unattended. Turn the power OFF.
23. Maintenance. For your safety, service and maintenance should be performed
regularly by a qualified technician.
note: Performance of this tool may vary depending on variations in local line voltage. Exten-
sion cord usage may also affect tool performance.
Warning:the warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. it must be under-
stood by the operator that common sense and caution are factors which cannot be built
into this product, but must be supplied by the operator.

3.
Secure the Drill Press Base to the floor using 7/16 inch bolts (not supplied).
Locate the Drill Press in an area where you walk around it unhampered.
Avoid kickback and grabbing by clamping the workpiece to the table, or use a vise that
is secured to the table. If the workpiece begins to spin, do not attempt to stop it with
your hands. Turn the motor OFF, and wait until it stops spinning before attempting to
remove it.

7.
Avoid being caught and pulled into the spinning chuck. Do not wear gloves, long
sleeve shirts, ties, or jewelry. Long hair must be bundled behind the head.
Never place hands and arms near the workpiece to avoid the possibility of the
workpiece coming loose and striking you.
Before drilling, turn on the motor and check for bit wobble or machine vibration. If this
is found, correct the problem before drilling.
Set the proper spindle speed for the specific drilling operation.
