PREFACE

IMPORTANT: READ LUBRICATION INSTRUCTIONS ON PAGE 8

BEFORE USING THIS MACHINE

This machine is suitable for drilling, reaming or thread cutting in metal, wood or plastic. The reversing

feature allows the removal of a thread cutting tap. It is widely used for short part runs or high production.

Read the instruction manual carefully for the operation and maintenance of this machine. Keep the

machine in a good operational condition and keep it clean. The machine is powered by a 110-Volt single-

phase line voltage but the control box (4830) powers a 3-phase, 220-Volt electrical motor at innitely

variable speeds. Some machines are furnished with a control box (4831) for 220 Volt, single phase in

and 220 Volt 3-phase out. The control box was programmed at the factory. The program should not be

changed by the operator.

INSTALLATION INSTRUCTION

The Ellis Variable Speed Drill Press is crated and shipped completely assembled. Check for any transit

damage at the time you accept delivery. Surfaces that are not painted are protected with a lm of heavy

oil during shipment. Remove this oil after uncrating. It is VERY important to remove this oil from the

inside taper bore using mineral spirits or paint thinner by twisting a rag up into the bore.

1. After uncrating, place the drill press on a at, solid oor and within reach of the power cord to a 110-

Volt, 60 HZ Single Phase grounded power outlet. (Some machines are built for 220-Volt single phase.)

Make certain that the supply Voltage is 110 Volt (220-Volt). A long extension cord or a low supply

Voltage can cause serious problems. The wire connections at the terminals have to be reliably tight.

Do not plug into a power receptacle until the rest of the installation is nished.

Warning:

Adapters, extension cords and surge protectors should not be used with this product. Also a GFCI (Ground

Fault Circuit Interrupter) protected receptacle cannot be used. It is recommended to use a 20 amp, 115-

Volt, AC dedicated circuit.

2. If the oor is uneven and the drill press rocks, place shims under the base to remove any motion. For

light work the machine can stand on the oor by itself. It is advisable to bolt the machine to the oor

when large work pieces are drilled. Four openings are provided in the column base for foundation bolts.

3. For optimum performance the Variable Speed Control assembly is preset at the factory. The circuit is

protected by two fast blow ceramic fuses.

Do not tamper with the wiring or settings inside the Variable Speed Control Box.

SAFETY

DISCONNECT THE POWER CORD FROM THE WALL OUTLET BEFORE ANY MAINTENANCE.

CONTROL BOX AND MOTOR

1. Do not open the Control Box. Tampering with the wiring or setting will void the warranty. The circuit

board is not eld repairable. Do not touch or adjust anything without calling Ellis Manufacturing Co. for

instructions. The circuits in the control box are not isolated. Elements of the circuit board are at 230 Volt.

Direct contact with these circuits can cause serious injury.

2. The control circuit is not fail-safe. A disconnect at the wall outlet is the only way to reliably disable the control.

3. While power is ON or for some time after power-OFF, do not touch the inverter since the inverter will be

extremely hot. Doing so can cause burns.

WARNING

• While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an

electric shock.

• Do not run the inverter with the front cover or wiring cover removed. Otherwise you may access the exposed

high voltage terminals or the charging part of the circuitry and get an electric shock.

• Even if power is OFF, do not remove the front cover except for wiring or periodic inspection. You may access

the charged inverter circuits and get an electric shock.

• Before wiring or inspection, power must be switched OFF. To conrm that, LED indication of the operation

panel must be checked. (It must be OFF.) Any person who is involved in wiring or inspection shall wait for at

least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage

using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is

dangerous.

• This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national

and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable

standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN

standard must be used.

• Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.

• The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.

• Setting dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise

you may get an electric shock.

• Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an

electric shock.

• Do not change the cooling fan while power is ON. It is dangerous to change the cooling fan while power is ON.

• Do not touch the printed circuit board with wet hands. Otherwise you may get an electric shock.

• When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1s at powering

OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

OPERATING SAFETY

1. Always wear safety glasses

2. Do not wear gloves, necktie, loose clothing, jewelry or other items that may get caught in moving parts. Long

hair should be tied up and under a cap.

3. Do not hold the part to be drilled by hand. Clamp the work or brace it against the drill press column to prevent

rotation or use the Safety Drill Press Vise; see the enclosed installation sheet about the Safety Drill Press

Vise. Two T-Slots are provided in the table and column base to aid clamping.

4. Use recommended speeds that are proper for the drill, the material being drilled and accessories used.

5. Make a habit of removing the chuck key, drift key and other wrenches after their use.

6. Keep hands and ngers clear of the drill bit or cutter.

7. Shut off the power before removing the drill bit or cutting tool.

8. Do not try cutting or similar operations by moving the table or the head stock with respect to each other. Be

sure that the head stock and table are securely clamped to the column.

9. Be sure the drill bit or cutting tool is securely clamped in the chuck.

10. Keep belt guard in place and closed.

11. Do not operate the machine beyond its capacity and possibly overload the power train.

12. Maintain the machine regularly, keep it clean and keep a maintenance and lubrication log.

SPEED CHANGE

A quick Speed (Torque) Range change can

be accomplished with the Ellis HI-Lo Handle

on the right side of the machine. (See the

enclosed instruction sheet.) Note: The motor

must rotate at a moderate speed to change the

operating speed range selection. The variable

speed control can vary the speed innitely

within each speed (Torque) range setting

which is explained in the next paragraph.

LOW SPEED HIGH TORQUE OPERATION

It is highlly recommended to shift into low using

the “Ellis High/Low Shift” For big drills, tapping

and hole saws see pages 14 and 15 for more information.

ELECTRICAL CONTROL BOX

Set up

DO NOT PLUG INTO A GFI CIRCUIT.

Start Turn the BIG RED EMERGENCY button clockwise (in the direction of the arrows) so that the button will

pop out and the read out window will light up. Turn the Forward/Reverse switch to the reset position then to the

desired direction of forward or reverse.

Set Button The small (middle) white SET button changes the read-out display in the number window. When

the letter “A” lights up beside the window it shows the ampere draw of the motor. The voltage is shown when

there is no letter on display.

Speed Push the small white SET button until you see the letters “HZ”. Now the read-out window displays the

frequency in cycles/seconds. That feature controls the speed of the motor. This is NOT the RPM of the spindle

but represents a reference that is relative to the spindle speed. (120 HZ = 100% of the spindle speed)

Speed Change The BLACK button in the upper left hand corner regulates the spindle speed. It works in both

the forward and reverse mode. Spinning the black knob in the the upper left corner regulates the spindle speed.

A clockwise rotation of the knob increases spindle speed in both the forward and reverse directions.

Forward Switch Position Use the Forward Switch Position for standard drilling, tapping and hole saw cutting.

Reverse Switch Position Use the Reverse Switch Position to retract a tap or to tap a left hand thread. Keep

downward pressure on the feed handle when backing a tap out of the work piece.

Stop/Reset Switch Position This setting stops the motor from either forward or reverse rotation. Use this as

the STOP switch while operating the drill press during the day. Reset to the position after a power outage or

after hitting the BIG RED EMERGENCY BUTTON.

Stop The BIG RED button stops the machine and automatically disconnects the machine from electrical

power after a time delay of about twenty seconds. Use this as the Power Off switch at the end of the day.

Note: Avoid stalling the spindle and stopping the motor under

power; the resulting current surge can damage the electronic

components in the control box. Turn Power off immediately

in a stalled motor condition. Clear the jam mechanically.

Repeated stalling abuse is detectable and can lead to voiding

the warranty.

POWER TRAIN

Spindle Speed

The motor drives the middle pulley and the spindle pulley by a V-Belt. The spindle pulley drives the

spindle and the taper sleeve. The spindle speed is variable by means of the variable speed control box

or with Ellis Hi-Lo handle. Forward and reverse rotation of the spindle is selected on the control box

panel. If you have any problems with this, call the factory.

Power Feed and Manual Feed

Spindle feed can be accomplished in two modes: manual and by power. Manual Feed is accomplished

by turning the turn style (8474) at the right side of the head stock. Pulling any of the two turn styles

to the right engages the power feed and returning it to the left stops the power feed. The thumbscrew

(7027) must be loosened to engage the power feed, and tightening this thumbscrew prevents the

machine from actually engaging in the power mode. Use the power feed only when the spindle

rotates in the CW (clockwise) rotation. Do not use power feed in the tapping mode.

DEPTH OF DRILLED HOLE

Do not use the depth dial for through holes: unlock the locking clamp on the face of the depth dial.

Proceed as described in the following for drilling holes to preset depth:

1. Stop the spindle rotation. Loosen the locking handle on the depth scale hub. Lower the drill end to

the desired drill depth by turning the turn style. Turn the dial CCW (counter clockwise) as you face

the end of the turn style hub. Lock the locking clamp when the dial comes to a stop.

2. Note: When drilling through holes, place a block of wood or scrap piece of metal under the work

piece to prevent drilling into the table or use an Ellis Safety Drill Press Vise.

3. The machine is equipped with a power feed overload clutch. The overload clutch protects the feed

power train from damage if too high a feed rate or too high a spindle speed is used. The overload clutch

disengages when you hear a clicking noise. Reduce the feed rate or spindle speed when this occurs.

The overload torque at which the clutch disengages can be increased by turning the adjustment

screws clockwise and can be decreased by turning the adjustments screw counterclockwise. There

are two adjustment screws in the pulley groove at 180 degree from one another.

Note: Do not tighten the screws too far because

a solid spring cannot let the ball escape from

the groove in the shaft. In this case the overload

clutch would be rendered useless and damage

can occur. To set the maximum torque: turn each

set screw until tight and then back them out by two.

DRILL CHUCK AND TAPER SHANK DRILL ATTACHMENT

The size of the taper to be used with this machine is a Morse # 3 Taper. It is important to wipe the inside

taper in the spindle and the outside of the chuck taper or drill taper clean of oil or dirt. Insert the arbor

into the spindle and twist to align the tang with the slot in the spindle then thrust upward sharply to seat

the chuck. Follow the same procedure for a taper shank drill or accessory. A wood hammer can assist in

doing this.

REMOVING DRILL CHUCK OR DRILL FROM SPINDLE

Loosen the locking handle on the depth scale collar. Lower the quill until the slot is completely uncovered.

Grasp the locking handle and turn the collar CW (clockwise) as you face the end of the style handle body.

Lock the handle securely when the collar comes against a stop. Turn the spindle until its slot lines up with

the one in the quill. Insert the drift key into the slot. Hold the chuck or drill with one hand while tapping on

the drift key with a hammer.

DRILL SPEEDS AND USAGE

The speed at which the drill has to rotate for efcient cutting depends on the type of material being

worked and the diameter of the drill. Use a squirt bottle to add cutting oil (uid) to the drill. Retract the drill

often when deep holes are drilled; this removes chips. Use a low Spindle Speed (Torque) for tapping a

threaded hole. Use a heavy oil or thread cutting uid to lubricate the tap. Reverse the spindle rotation with

the reverse switch on the variable speed control panel to retract the tap.

ELEVATING, ROTATING AND CLAMPING THE TABLE

The table can rotate 360 degrees and move up and down on the column. Loosen both clamp screws,

rotate the table in the required position, elevate the table by means of the elevation handle and tighten

both clamp screws again.

LUBRICATION

The power feed gear box at the right side of the head stock has a grease tting. Another grease tting is

at the left side near the sight window, see next page.

LUBRICATION SCHEDULE

Location Suggested Lubricant Frequency

Grease Nipple Lithium Grease N.L.G.I. # 2 Daily or twice daily under heavy use

Under light use, grease at least every other day. It is much more important that you grease the

machine frequently than to worry about the type of lubricant used. Do not mix synthetic and

mineral base oils.

Maintenance

Keep table and sliding parts clean of dirt and chips. Every 3 months lower the quill, wipe clean and oil

lightly. If raising the table becomes difcult, clean and wipe the column with light machine oil. The ball

bearings in the motor, quill and V-Belt pulleys are lubricated for life. Keep the cooling ns of the speed

control box and the motor clean and free of dirt and dust.
