supply while servicing.
- Always follow instructions in Operating Instructions
and Parts Manual when changing accessory tools
or parts.
- Never modify the machine without consulting JET
Corporation.
You—the stationary power tool user—
hold the key to safety.
Read and follow these simple rules for best results
and full benefits from your machine. Used properly,
JET’s machinery is among the best in design and
safety. However, any machine used improperly can
be rendered inefficient and unsafe. It is absolutely
mandatory that those who use our products be
properly trained in how to use them correctly. They
should read and understand the Operating Instruc-
tions and Parts Manual as well as all labels affixed to
the machine. Failure in following all of these warnings
can cause serious injuries.
1. Always wear protective eye wear when operating
machinery. Eye wear shall be impact resistant,
protective safety glasses with side shields which
comply with ANSI Z87.1 specifications. Use of
eye wear which does not comply with ANSI Z87.1
specifications could result in severe injury from
breakage of eye protection.
2. Wear proper apparel. No loose clothing or
jewelry which can get caught in moving parts.
Rubber soled footwear is recommended for best
footing.
3. Do not overreach. Failure to maintain proper
working position can cause you to fall into the
machine or cause your clothing to get caught —
pulling you into the machine.
4. Keep guards in place and in proper working
order. Do not operate the machine with guards
removed.
5. Avoid dangerous working environments. Do not
use stationary machine tools in wet or damp
locations. Keep work areas clean and well lit.
6. Avoid accidental starts by being sure the start
switch is “OFF” before plugging in the machine.
7. Never leave the machine running while unat-
tended. Machine shall be shut off whenever it is
not in operation.
8. Disconnect electrical power before servicing.
Whenever changing accessories or general
maintenance is done on the machine, electrical
power to the machine must be disconnected
before work is done.
9. Maintain all machine tools with care. Follow all
maintenance instructions for lubricating and the
changing of accessories. No attempt shall be
made to modify or have makeshift repairs done to
the machine. This not only voids the warranty but
also renders the machine unsafe.
10. Machinery must be anchored to the floor.
11. Secure work. Use clamps or a vise to hold work,
when practical. It is safer than using your hands
and it frees both hands to operate the machine.
12. Never brush away chips while the machine is in
operation.
13. Keep work area clean. Cluttered areas invite
accidents.
14. Remove adjusting keys and wrenches before
turning machine on.
15. Use the right tool. Don’t force a tool or attach-
ment to do a job it was not designed for.
16. Use only recommended accessories and follow
manufacturers instructions pertaining to them.
17. Keep hands in sight and clear of all moving parts
and cutting surfaces.
18. All visitors should be kept at a safe distance from
the work area. Make workshop completely safe
by using padlocks, master switches, or by
removing starter keys.
19. Know the tool you are using — its application,
limitations, and potential hazards.
- Misuse of this machine can cause serious injury.
- For safety, machine must be set up, used and
serviced properly.
- Read, understand and follow instructions in the
Operating Instructions and Parts Manual which
was shipped with your machine.
When setting up machine:
- Always avoid using machine in damp or poorly
lighted work areas.
- Always be sure the machine support is securely
anchored to the floor or the work bench.
When using machine:
- Always wear safety glasses with side shields (See
ANSI Z87.1)
- Never wear loose clothing or jewelry.
- Never overreach—you may slip and fall.
When servicing machine:
- Always disconnect the machine from its electrical

General electrical cautions
This drill press should be grounded in accordance with the National Electrical Code and local codes and
ordinances. This work should be done by a qualified electrician. The saw should be grounded to protect the
user from electrical shock.
Wire sizes
Caution: for circuits which are far away from the electrical service box, the wire size must be increased in
order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and
burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is
recommended.

Safety Instructions for Drill Presses
1. All work shall be secured using either clamps or
a vise to the drill press table. It is unsafe to use
your hands to hold any workpiece being drilled.
2. Drill press head and table shall be securely
locked to the column before operating the drill press.
This must always be checked prior to starting the
machine.
3. Always use the correct tooling. Tooling shall
always be maintained and properly sharpened. All
tooling must be run at the proper speeds and feeds
as they apply to the job. Use only recommended
accessories and follow those manufacturers instruc-
tions pertaining to them. Tooling shall be not be
forced in to any workpiece but fed according to the
proper specifications. Failure to follow these
instructions will not only ruin the tooling as well as
the machine, but can cause serious injury.
4. Never brush away any chips while the machine
is in operation. All clean up should be done when
the machine is stopped.
5. Keep hands in sight. Do not put hands or fingers
around, on, or below any rotating cutting tools.
Leather safety gloves should be used when handling
any sharp objects or cutting tools. See Figure A.
6. Always wear protective eye wear when operating,
servicing or adjusting machinery. Eyewear shall be
impact resistant, protective safety glasses with side
shields complying with ANSI Z87.1 specifications.
Use of the eye wear which does not comply with
ANSI Z87.1 specifications could result in severe
injury from breakage of eye protection. Figure B.
7. When drilling in material which causes dust, a
dust mask shall be worn. See Figure C.
8. Avoid contact with coolant, especially guarding the
eyes.
9. Non-slip footwear and safety shoes are recom-
mended. See Figure D.
10. Wear ear protectors (plugs or muffs) during
extended periods of operation. See Figure E.

Feeds for Drilling
The feed of a drill is governed by the size of the tool
and the material drilled. Because the feed rate
partially determines the rate of production and also is
a factor in tool life, it should be chosen carefully for
each job. In general, the most effective feeds will be
found in the following ranges:
Diameter of Drill Feed per Revolution
(inches) (inches)
Under 1/8 .....................0.001 to 0.002
1/8 to 1/4 ...................... 0.002 to 0.004
1/4 to 1/2 ...................... 0.004 to 0.007
1/2 to 5/8 ...................... 0.007 to 0.015
Indication of Extreme Speeds and Feeds
A drill that splits up the web is evidence of too much
feed or insufficient tip clearance at the center as a
result of improper grinding. The rapid wearing away
of the extreme outer corners of the cutting edges
indicates that the speed is too high. A drill chipping
or braking out at the cutting edges indicates that
either the feed is too heavy or the drill has been
ground with too much tip clearance.

In cases where carbon steel drills are applicable, the
drill should be run at speeds of from 40 to 50 percent
of those given above.
Operating Precautions
The following operating and safety precautions must
be observed in order to avoid harm to the operator or
damage to the drill press.
1. The head assembly must be locked to the
column so the thrust produced by drilling will not
force the head assembly up the column.
2. The work table must be locked to the column so
it will not be forced down the column.
3. Before drilling, release the quill lock nut to
permit free travel of the quill.
4. Be sure the belt is tightened to the proper
tension.
5. DO NOT start to drill the workpiece until making
certain the workpiece is held down securely.
6. MAKE SURE THE DRIVE MOTOR IS RUN-
NING BEFORE turning the speed control
handwheel in either direction.
7. Point of operation protection is required for
maximum safety. This remains the responsibil-
ity of the user/purchaser since conditions differ
between jobs.
8. Make sure the drill is secured in the spindle or
check before attempting to use the drill press.
9. Make sure the spindle taper is clean and free of
burrs, scoring, and galling to assure maximum
gripping.
10. Lock the quill in position when using and side-
loaded tool.
Drilling Recommendations
Speeds for Drilling
The speed of a drill is usually measured in terms of
the rate at which the outer periphery of the tool
moves in relation to the work being drilled. The
common term for this is Surface Feet per Minute
(SFM). The relationship of SFM is expressed in the
following formulas:
SFM = 0.26 X rpm X Drill Diameter (in inches)
RPM = 3.8 x ________SFM__________
Drill diameter (in inches)
In general, the higher the speed the shorter the drill
life. Operating at the low end of the speed range for
a particular material will result in longer life. The most
efficient speed for operating a drill depends on many
variables:
1. Composition and hardness of material.
2. Depth of the hole.
3. Efficiency of the cutting fluid.
4. Type and condition of the drilling machine.
5. Desired quality of the hole.
6. Difficulty of set-up.
