For your own safety, read the owner’s manual before operating the drill press.
This drill press is designed and intended for use by properly trained and experienced personnel
only. If you are not familiar with the proper and safe operation of a drill press, do not use until
proper training and knowledge has been obtained.
•KEEP GUARDS IN PLACE and in working order.
•KEEP ALL BODY PARTS AWAY FROM MOVING PARTS. Avoid placing any part of your body
near belts, cutters, gears, etc.
•REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit of checking to see that keys and
adjusting wrenches are removed from the machine before turning it on.
•KEEP THE WORK AREA CLEAN. Cluttered areas and work benches invite accidents.
•DON’T USE IN A DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet locations,
or expose them to rain. Keep work area well lighted.
•KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area.
•MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
•DON’T FORCE THE MACHINE. It will do the job better and more safely at the rate for which it was
designed.
•USE THE RIGHT MACHINE. Don’t force a machine or attachment to do a job for which it was not
designed.
•USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough to carry the current your machine will
draw. An undersized cord will cause a drop in the line voltage resulting in power loss and
overheating. If in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the
heavier the cord.
•WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective
hair covering to contain long hair.
•ALWAYS USE SAFETY GLASSES. Also use face or dust masks if the cutting operation is dusty.
Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.
•DON’T OVERREACH. Keep proper footing and balance at all times.
•MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for the best and safest performance.
Follow instructions for lubricating and changing accessories.
•ALWAYS DISCONNECT THE MACHINE FROM THE POWER SOURCE BEFORE SERVICING.
•REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure the switch is in the off position
before plugging in.
•NEVER STAND ON A MACHINE. Serious injury could occur if the machine tips or if the drill bit is
unintentionally contacted.
•CHECK DAMAGED PARTS. Before further use of the machine, a guard or other part that is
damaged should be carefully checked to determine that it will operate properly and perform its
intended function - check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced.
•NEVER LEAVE THE MACHINE RUNNING UNATTENDED. TURN POWER OFF. Don’t leave the
machine until it comes to a complete stop.
•SOME DUST created by power sanding, sawing, grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
•Lead from lead based paint.
•Crystalline silica from bricks, cement and other masonry products.

5
•Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area and work with approved safety
equipment, such as face or dust masks that are specifically designed to filter out microscopic
particles.

Read and understand the
entire contents of this manual before
attempting set-up or operation. Failure to
comply may cause serious injury.
Unpacking and Clean-Up
1. Remove the shipping crate.
2. Remove the protective coating from all rust
protected surfaces with a soft cloth moistened
with kerosene or a mild solvent. Do not use
acetone, gasoline, or paint thinner, as these
may damage painted surfaces.
3. To prevent rust, apply a thin coat of metal
sealer to the table.
Lifting the JDP-20EVS
Keep people a safe distance
away from the drill press while it is being
moved. Failure to comply may cause damage
to property and/or serious bodily injury.
1. Make sure the two head locking bolts (refer to
A, Fig. 4) are tight prior to lifting.
4. Position the JDP-20EVS next to the area that
will be used for the machine.
5. The “Lifting Point” should be used to raise the
drill press off of the shipping pallet.
6. Lift the machine at the “Lifting Point” with a
forklift. Use a 2x4 on the fork to protect the
head.
NOTE: You should remove the coolant hose
holder so that it is not damaged during lifting.
Installation
The drill press must be located in a dry, well-lighted
area with adequate room on all sides of the
machine. The floor must be level and the drill press
must rest solidly on the floor. The most accurate
and vibration free operation will require the drill
press to be bolted to the floor. While this is not
absolutely necessary, it is highly recommended.
Place shims near the four bolt holes to level the
drill press, if necessary. Figure 2 shows the hole
dimensions of the base. Equal pressure should be
applied to all four nuts when tightening to prevent
distortion of the base.
Figure 1
Figure 2

7
Electrical Connections
A qualified electrician must
complete all electrical connections. All
adjustments or repairs must be done with the
drill disconnected from the power source.
Failure to comply may result in serious injury.
The motor for the JDP-20EVS/230 is rated at 2HP,
3PH 230V only. The machine can also be run on
1-Phase power by hooking up the ground, L1 and
L2 wires, as explained below.
The motor for the JDP-20EVS/460 is rated at 2HP,
3PH, 460V only.
The JDP-20EVS Drill Press is not supplied with a
power cord. To connect power, you may either
install a power cord with a UL/CSA listed plug, or
hard wire the machine directly to a service panel.
If the drill press is to be hard-wired to a panel,
make sure a disconnect is available for the
operator. (During hard-wiring of the machine, make
sure the fuses have been removed or the breakers
have been tripped in the circuit to which the drill
press will be connected.)
If using a power cord, strip back the cord until
about 3 to 4 inches of the lead wires are exposed.
Slide a grommet onto the cord to be installed later
in the control box hole, to prevent stress to the
power cord.
1. Bring the lead wires through the hole in the
side of the control box and connect as follows
(refer to Figure 3):
2. If your incoming power is single phase,
connect the two leads to L1 and L2, and the
green ground wire to the grounding screw.
3. If your incoming power is three phase,
connect the three leads to L1, L2 and L3, and
the green ground wire to the grounding screw.
This drill press must be properly grounded.
Make sure the green ground wire is secured to the
grounding screw as described.
Make sure the power available matches the power
requirement of the drill. When the drill is connected
properly, the spindle turns clockwise in a
conventional drilling rotation. If the spindle does
not turn clockwise, disconnect the drill from the
power supply and reverse two of the three power
leads (except ground wire green).

Raising the Head
The drill press head is lowered on the column for
crating and transportation. Before operating the
drill press, the head will need to be raised to the
operational level.
To raise the head:
1. Loosen the two head locking bolts (A, Figure
4) by turning counterclockwise. Make sure the
two screws (C, Figure 4) in the lock collar (B)
are tight.
2. Take the head and turn it slightly from side to
side (Figure 5) to loosen the rust prevention
solution on the column
3. Loosen the table lock by placing the handle on
the crankshaft (A, Fig. 7) and rotating the
handle counter-clockwise
4. Cut a 2x4 approximately 16” in length.
5. Raise the table by placing handle on
crankshaft (B or C, Figure 7) and rotating
clockwise. Snug the 2x4 between the table
and the head as close to the column as
possible. Caution: Do not place the 2x4 under
the lock collar (B, Fig. 6).
6. Use the table lift crank on a shaft (B or C, Fig.
7) to raise the head and 2x4 until the head
bore and the column are flush. CAUTION:
When the head bore and the column cap are
flush, the head cannot be raised anymore. Use
a ladder to observe the column through the top
of the belt cover.
7. Tighten the two head locking bolts (A, Fig. 4).
This will hold the head in place until the lock
collar can be moved into position. The 2x4 can
now be safely removed.
8. After the head is set at the desired height,
loosen two set screws (C, Fig. 4) on the lock
collar.
9. Slide the lock collar up the column until it is
flush with the head.
10. Firmly tighten the two setscrews on the lock
collar (C, Fig. 4).
To lower the head, reverse the steps above. Do
not loosen the head locking bolts without
supporting the head.

NOTE: The Electronic Variable Speed unit is
designed to shut down, to prevent harm to the
system, in the event of overloading the spindle.
Make sure the Speed Control Knob and the High-
Low Handle are in the matching ranges for the
work being done. Drilling large holes requires the
High-Low Handle to be in ‘Low’ mode and the
Speed Control Knob to be selecting a speed that is
high enough to power the large bit.
Adjusting the Depth Stop for Drilling
Place the drill/tap switch (7, Fig. 10) in the drill
mode. Adjust the zero reading on the scale as
follows:
1. Lower the quill to the bottom of its stroke by
turning the handle (A, Fig. 10) counter-
clockwise until it stops, and hold in that
position.
2. To set the zero, loosen lock knob (B, Fig. 10).
Turn the knurled knob (C, Fig. 10) until the
pointer reads zero.
3. To set the depth stop, turn the knurled knob
(C, Fig. 10) to the desired setting. Tighten
lock knob (B, Fig. 10). The quill will now
advance to this setting.
Adjusting the Depth Stop for Tapping
Place the drill/tap switch in the tap mode. To adjust
the depth stop for tapping, follow the instructions
for adjusting the depth stop for drilling. The major
differences in the tap mode are two micro-
switches.
1. Advance the quill, releasing the upper limit
switch for tapping.
2. The spindle will reverse directions upon
triggering the lower limit switch.
Spindle Preparation
Thoroughly clean the inside of the spindle with a
soft dry cloth. Also clean any taper or arbor to be
used in the spindle. If these are not kept clean, the
taper or arbor will not “seat” properly in the spindle
and may drop out unexpectedly.
Figure 9
Figure 10

Installing Tools into the Spindle Bore
1. Disconnect the machine from the power
source.
2. Make sure the spindle bore and the tool are
clean and free of oil.
3. Place a protective piece of scrap wood on the
table.
4. Raise the table to approximately 8” to 10”
below the spindle.
5. Insert the Morse Taper #3 tool into the spindle.
6. Lower the spindle, with the handle assembly,
and seat the tool against the wood.
Removing Tools from Spindle Bore
1. Disconnect the machine from the power
source.
2. Place a protective piece of scrap wood on the
table.
3. Raise the table to approximately 8” to 10”
below the spindle.
4. Lower the spindle to expose the slots in the
spindle wall.
5. Insert the drift key (A, Fig. 11) into the spindle
slots and tap gently until the drill bit or chuck
arbor loosens.
Coolant Pump
The coolant tank should be filled with 2 gallons of a
cutting coolant. Fill by pouring coolant into the
base of the machine. Add coolant in the same
manner when coolant is low. To drain coolant,
remove hex cap screw located on the lower
backside of the base. Follow all coolant
manufacturer’s instructions for safety, mixing
disposal, etc.
Make sure the drain hose has a good tight
connection into the table and that the coolant flows
into the base.
Make sure the hose leaving the pump and entering
the ball valve has good tight connections.
The flexible nozzle enables the user to adjust the
coolant for each job. There is one ball valve that
turns the coolant to the nozzle on, or off.
Figure 11
Figure 12
Adjusting the Spindle Return Spring
The spindle return comes pre-set from the factory
and should not need adjustment. If future attention
is ever required, proceed as follows:
1. Do NOT remove the spring cap (B, Fig. 12).
2. Loosen knob (A, Fig. 12) just enough to rotate
the spring cap past the notch (C, Fig. 12).
3. Rotate the spring cap clockwise to decrease
spring tension. Rotate the spring cap counter-
clockwise to increase spring tension.
4. Re-tighten the knob (A, Fig. 12).
