INTRODUCTION

The single and three phase Low Voltage Control

(LVC) motor starters have been designed exclusively for

use on stationary power tools.
The basic function of a definite purpose starter

is to provide ON-OFF motor control.
to providing ON-OFF control, every motor starter
offers the following features:

MOTOR OVERLOAD PROTECTION ­All starters are supplied with thermal overload

relays which protect the power tool motor from

burnouts due to excessive heat resulting from a

sustained motor overload, extended motor cycling
or stalled rotor.

In addition

NO VOLTAGE OR LOW VOLTAGE PROTECTION (LVP) -

No voltage or low voltage protection prevents the
dangerous restarting of a power tool following

a temporary power failure. Upon a loss of voltage
or a reduction of voltage, the magnetic contactor
in the starter will open. When power is restored,
the motor will not automatically restart, but must
be manually restarted by pushing the start button
of the ON-OFF switch.

LOW VOLTAGE CONTROL (LVC) -

The definite purpose motor starters provide low

voltage control as a unique safety feature.

pushbutton ON-OFF switch operates at a 24 volt

level, not at line voltage.

control eliminates the possibility of electrical

shock to the operator.

SAFETY RULES FOR ALL TOOLS

1. KNOW YOUR POWER TOOL. Read the own­er’s manual carefully. Learn the tools applications
and limitations, as well as the specific potential

hazards peculiar to it.

2. KEEP GUARDS IN PLACE and in working

order.

3. GROUND ALL TOOLS. If tool is equipped

with three-prong plugs, it should be plugged into a
three-hole electrical receptacle. If an adapter is

used to accommodate a two-prong receptacle, the
adapter lug must be attached to a known ground.
Never remove the third plug.

4. REMOVE ADJUSTING KEYS AND WRENCH­ES. Form habit of checking to see that keys and

adjusting wrenches are removed from tool before

turning it on.

5. KEEP WORK AREA CLEAN. Cluttered areas

and benches invite accidents.

cause hazards.

18. AVOID ACCIDENTAL STARTING. Make
sure switch is in “OFF” position before plugging
in cord.

19. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the cutting
tool is accidentally contacted.

20. CHECK DAMAGED PARTS. Before further

use of the tool, a guard or other part that is dam­aged should be carefully checked to ensure 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.

USE RECOMMENDED ACCESSORIES.

The use of improper accessories may

blade or cutter against the direction of rotation
of the blade or cutter only.

22. NEVER LEAVE TOOL RUNNING UN­ATTENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.

23. DRUGS, ALCOHOL, MEDICATION. Do not

operate tool while under the influence of drugs,

alcohol or any medication.

24. BE SURE drill bit or cutting tool is securely
locked in the chuck.

25. BE SURE chuck key is removed from the
chuck before turning on power.

26. ADJUST the table or depth stop to avoid dril­ling into the table.

27. SHUT OFF the power, remove the drill bit or

cutting tool, and clean the table before leaving the

machine.

28. CAUTION: When practical, use clamps or a

vise to secure workpiece to keep the workpiece
from rotating with the drill bit or cutting tool.

29. WARNING: For Your Own Safety – Don’t
wear gloves when operating a drill press.

SETTING UP

The head and table of your drill press have been
lowered on the column for convenience in packaging.
To raise the head, proceed as follows:

1. Place a block of wood, about 7“ long, between the
drill press head and the table, as close to the column
as possible.

2. Make sure the collar at the bottom of the raising
mechanism rack is tight on the column and unlock
the table clamp.
right hand side of the head, that locks the head to the
column.

3. Turn the raising mechanism hand crank clockwise
to raise the table and head simultaneously.

4. When the table approaches the top of the raising
mechanism rack, lock the table and head to the col-

umn. Then loosen the raising mechanism collar and
turn the raising mechanism hand crank counterclock-

wise. This will slide the rack of the raising mecha­nism further up the column.

5. Repeat STEPS 2, 3 and 4 until the top of the head
is at the desired height. Be sure not to raise the top
of the head casting beyond the top end of the col­umn.

6. With the head and table still loose, visually line up
the spindle with the center of the base and lock the
head to the column. Make sure the safety collar is
locked in place underneath the head.

Then loosen the nut located on the

RAISING MECHANISM

All models are furnished with a rack and pinion type
raising mechanism. The single spindle floor models
use the unit in conjunction with the table, and all
other models have it attached to the head.

If on single spindle floor models, a raising mechanism
is desired in the head also, it will be necessary to pur­chase the 20-761 Accessory Head Raising Mechanism.

CLEANING THE MACHINE

The table and all other machined or unpainted sur­faces of the drill press are protected with a coating of

rust preventive. This coating may be removed with a
soft cloth moistened with kerosene (do not use ace­tone, gasoline or lacquer thinner for this purpose.)
After cleaning, cover all unpainted surfaces with a

light film of good machine oil.

7. Position the table and raising mechanism to the
desired position on the column and lock them in
place.

MULTIPLE SPINDLE MODELS

In the case of multiple spindle models, the legs are
not attached to the table, they are packed separately.
To assemble the legs to multiple spindle models, care­fully support machine on wooden horses or other
temporary supports and bolt legs securely into posi­tion. The tables of multiple spindle models should be
carefully leveled. Use a precision level on the table
and place wedges under legs of the machine where re­quired. Riser blocks, Cat. No. 50-400, one or two
sets per leg, may be used if it is desired to have the

table two or four inches higher.

ELECTRICAL CONNECTIONS

If the motor on your machine is wired for 230V single

phase, the power cord is equipped with a plug that has
two flat, current-carrying prongs in tandem, and one
round or “U’’-shaped longer ground prong. This is used
only with the proper mating 3-conductor grounding
type receptacle, as shown in Fig. 1. When the three-

prong plug on your machine is plugged into a ground­ed, 3-conductor receptacle, the long ground prong on
the plug contacts first so the machine is properly
grounded before electricity reaches it.

If the motor on your machine is wired for 200V, 230V

or 460V three phase, the necessary wiring from the
starter to the power source should be completed by a
competent electrician.

IMPORTANT: Make sure the electrical characteristics

are the same between the motor nameplate and the
power source and make sure the power circuit the drill
press will be used on is properly fused and that the

wire size is correct, as shown in Fig 2. MAKE SURE

THE DRILL PRESS IS PROPERLY GROUNDED.

SPINDLE SPEEDS

With the Step Pulley
you get eight selected speeds with full HP at the spin-

dle at all speeds. The speeds available with your dril­ling machine are 375, 600, 900, 1275, 1800, 2400,
3075 and 4250 RPM. The highest speed is obtained
when the belt is on the largest step of the motor
pulley and the smallest step of the spindle pulley.

CHANGING SPEEDS

When changing speeds on your drilling machine, pro­ceed as follows:

1. DISCONNECT MACHINE FROM POWER

SOURCE.

2. Loosen wing nut located on the opposite end of the
plate (A) Fig. 3. (This wing nut is shown at (D) Fig.

6). The motor and motor plate can then be tilted

forward, as shown in Fig. 3, releasing the belt tension.

3. Open the door (B) Fig. 3, tilt the motor pulley (C)
forward, and move the belt to the desired steps on the
motor and spindle pulleys, as shown in Fig. 3.

4. After the belt is positioned on the pulleys, close
the door (B) Fig. 3, and tighten the wing nut located
on the opposite end of the plate (A) to keep the motor
pulley, motor and motor plate in the vertical position.

CHANGING SPINDLES

To change the spindle for any reason, proceed as fol­lows:

1. Remove the two nuts and washer (A) Fig. 4.

2. Carefully pull out the return spring and housing
(B) Fig. 4 about 1/4” until roll pin (C) disengages
with the groove in the return spring housing and care­fully rotate the return spring housing to release ten­sion on the return spring or refer to the instructions
on page 7 under ADJUSTING SPINDLE RETURN
SPRING to release spring tension.

3. Disengage the return spring from the screw (D)
Fig. 6, in the pinion shaft, and remove the return
spring and housing from the pinion shaft.

4. Loosen screw (E) Fig. 4 and move retainer (F) up
out of the groove (G) in the pinion shaft.

5. Remove screw (D) Fig. 4, from pinion shaft and

while holding the quill with your left hand, remove
the pinion shaft (H) by pulling it straight out. The
quill assembly can then be easily removed from the
head casting.

6. Loosen the two set screws (A) in collar (B) Fig.
5 and remove collar.

7. With a hard rubber mallet, tap spline end of spin-

dle (C). The spindle (C) with bearing (D) and flinger
collar (E) will come out of the quill (F) Fig. 5.

8. Using an arbor press, remove bearing (D) and

flinger collar (E) from spindle (C) Fig. 5.

9. To replace spindle, reverse above procedure mak­ing sure the bearing (D) and flinger collar (E) have
been pressed tight against the shoulder on the spindle
(C) Fig. 5, before replacing spindle in quill.

10. After replacing collar with set screws (A & B)
Fig. 5, on the spindle, be sure there is not end play
between spindle and quill. Play is eliminated by
seating both bearings in quill.

11. When replacing quill in head casting, rotate spin-

dle if necessary to engage spline in pulley.

12. After the quill is replaced, adjust the spindle re-

turn spring.

ADJUSTING BELT TENSION

The correct belt tension is determined by the center to
center distance of the motor pulley (A) and the spindle

pulley (B) Fig. 6. If it ever becomes necessary to ad­just belt tension, proceed as follows:

1. Disconnect the machine from the power source.

2. Loosen the three screws (C) Fig. 6, and while mak­ing sure the motor pulley (A) is in parallel alignment
with the spindle pulley (B), move the motor and motor
plate (E) in or out until the center to center distance

between the motor and spindle pulley is 20”, as shown

in Fig. 6. NOTE: For clarity Fig. 6 is shown with the

belt guard removed.

QUILL ADJUSTMENTS

ADJUSTING SPINDLE RETURN

The quill can be locked at any desired point it its
travel, by tightening the quill locking handle (B) Fig.

7. This is an especially desirable feature for set-up of

tooling for production type operations.

After considerable use, play may develop between the
quill and the head casting due to wear. To compensate

for wear between the quill and head, proceed as fol­lows:

1. Make sure the quill locking handle (B) Fig. 7 is
loose.

2. Remove two screws and washers (E) Fig. 7. Only
one of the screws and washers (E) can be seen in Fig.

7. The other screw and washer is located on the left
front side of the head casting.

3. Tighten the two quill adjusting screws which are
located directly underneath the two screws and wash­ers (E) Fig. 7. It is not necessary to tighten these
screws too much.

4. Rotate pilot wheel to test movement of quill and
play. If there is a slight “drag”, quill adjusting screws
have been adjusted too tight. Back off quill adjusting
screws slightly. If the quill still has play, slightly

tighten quill adjusting screws.

5. After proper adjustment has been made, replace
screws and washers (E) Fig. 7.

SPRING

For the purpose of automatically returning spindle
upward after a hole has been drilled, a spring is pro­vided enclosed in a case and is located on the left side
of the drill press head. This spring has been adjusted
at the factory and should not be disturbed unless abso­lutely necessary. If it should become necessary to ad­just it, proceed as follows:

1. Remove the Micro-nut

sleeve (A) Fig. 7. and make sure the quill locking

handle (B) is loose.

2. Rotate the pilot wheel and lower the quill (C)
Fig. 7, until the rack on the back of the quill disen-

gages with the pinion shaft (D). A special design is
incorporated into the quill to prevent it from dropping
out of the head casting.

3. When the quill (C) Fig. 7. is lowered as far as pos-

sible, turn the pilot wheel counterclockwise to in­crease or clockwise to decrease the return spring
tension.

4. When the desired tension is obtained push up the

quill (C) until it engages with the pinion shaft (D) Fig.

7. The spring tension will then return the quill to the
up position.

5. Replace the

DRILLING HOLES TO DEPTH

SAFETY SUGGESTIONS FOR

When drilling one or two holes to a predetermined
depth, the calibrations on the face of the depth stop

rod (F) Fig. 7 can be used.

When drilling a number of holes to a predetermined
depth, or if a more exact setting is required, proceed
as follows:

1. Raise the locking sleeve (A) Fig. 7, and turn the

micro-nut (G) to the desired position on the stop rod

(F).

2, Lower the locking sleeve (A) so it will engage
micro-nut (G) Fig. 7. Lock sleeve (A) in place with
thumb screw if drill press is mounted in other than
vertical position. When the drill press is mounted with
the chuck pointing “up”,
micro-nut (G) Fig. 7, should be reversed on the stop
rod (F).

3. When locking sleeve (A) is in place on the micro­nut (G) Fig. 7, the micro-nut cannot be turned. When
a change in depth is required, the locking sleeve (A)
must be raised, and while it is raised, turn the micro­nut (G) the necessary calibration marks. Each mark
represents .002”. Then lower the locking sleeve (A).

4. The use of the micro-set stop nut will maintain the

24 VOLT LVC LOW VOLTAGE CONTROL

MAGNETIC MOTOR CONTROL SYSTEMS

INTRODUCTION - 24 VOLT LVC (LOW VOLTAGE
CONTROL) MAGNETIC MOTOR CONTROL SYS­TEMS

SAFETY RULES

1. Installing and servicing should always
plished by qualified electrical personnel.

be accom-

The single and three phase definite purpose Low
Voltage Control (LVC) motor starters have been de-

signed exclusively for use on stationary power tools.

The basic function of a definite purpose starter is to
provide ON-OFF motor control. In addition to pro­viding ON-OFF control, every motor starter offers the
following features:

MOTOR OVERLOAD PROTECTION - All starters
are supplied with thermal overload relays which pro­tect the power tool motor from burnouts due to ex-

cessive heat resulting from a sustained motor over-

load, extended motor cycling, or stalled rotor.

NO VOLTAGE OR LOW VOLTAGE PROTECTION
(LVP) - No voltage or low voltage protection pre-

vents the dangerous restarting of a power tool follow-

ing a temporary power failure. Upon a loss of voltage
or a reduction of voltage, the magnetic contactor in

the starter will open. When power is restored, the

motor will not automatically restart, but must be
manually restarted by pushing the start button of the
ON-OFF switch.

LOW VOLTAGE CONTROL (LVC) - The definite

purpose motor starters provide low voltage control
as a unique safety feature. The pushbutton ON-OFF
switch operates at a 24 volt level, not at line voltage.
The 24 volt low voltage control eliminates the possi­bility of electrical shock to the operator.

2. Read the instruction manual before wiring and
operating this motor starter. Failure to follow in­structions can cause injury.

Always disconnect the electrical power before

3.
removing the cover of the starter.

4. Operate the motor starter only with the cover of
the starter in place.

Do not operate the machine unless the motor

5.
starter is properly grounded as specified in the in­structions.

6. Follow national and local electrical codes when
wiring the motor starter.

7. Always use proper heater coils as specified in the
heater coil chart located on the inside of the starter

cover.

8. Make sure the motor starter is disconnected from
the electrical power source before the primary con­nections of the control transformer are changed.

9. Occasionally inspect the starter to ensure that it
is securely mounted, clean and dry.

This section includes a description of the basic LVC

motor starters, instructions for wiring the starters to
the power source, and instructions for changing the
voltage of a LVC motor starter.

THREE PHASE LVC MAGNETIC MOTOR STARTER

Fig. 13 illustrates the standard three phase LVC mo-

tor starter.

The three phase starter consists of four basic compo-

nents:
contactor, (3) transformer, (4) start/stop station.
The start/stop station is not shown in Fig. 13. Nei­ther are the input connections from the start/stop
station and the input connections from the three
phase motor or power supply.

A wiring diagram and schematic diagram of the three

phase LVC magnetic motor starter is shown in Fig. 12.

(1) overload block with heaters, (2) magnetic

FIG. 13 –STANDARD THREE PHASE MOTOR

STARTER

The wiring diagram indicates the relative physical
location of each component, wire, and terminal;
whereas, the schematic diagram does not show the
physical relationship of the components. The sche­matic diagram does show in straight line form the cir­cuit functions of the various components.
The three phase LVC motor starter is comprised of a
power circuit and a control circuit. The diagrams in
Fig. 12 illustrates the power circuit with heavy lines
to represent heavy gage wire sized for the motor cur­rent; whereas, the control circuit is shown with light
lines in the diagrams to represent light gage wire sized
for control current. In the motor starter, the power
circuit is wired with black wires, and the control cir­cuit is wired with red wires.

INSTRUCTIONS FOR CONNECTING THE THREE PHASE

MOTOR STARTER TO THE POWER SUPPLY

All three phase motor starters must be wired in the
field as follows: Refer to Fig. 10 and remove and dis­card the plastic plug covering the entrance hole in the

bottom of the starter enclosure. Bring the three
phase power lead through the entrance hole.

Connect three input power leads in terminals L1-L2-L3.

L2-L3 and the green ground lead to the ground strip
in the lower left-hand corner of the starter enclosure.

tor is turned on, simply interchange any two of the

Fig 12 - Connections for

(LVC) Motor Starter

Several points must be stressed and closely followed
when connecting the input power to the motor start­er.

1. To preserve the dust-tight integrity of the motor
starter, an oil-tight box connector should be used for
fastening the input cable to the starter enclosure at
the entrance hole.

2. If copper stranded wires are used for the input
leads, the wires must be soldered, dipped, or tinned
before they are connected to terminals L1-L2-L3 and
the ground strip.

3. The wires must be connected to terminals L1-L2­L3 through the front face of the terminal block as
shown in Fig. 11. The screws on the top of the termi­nal block are used for clamping the wires in the ter­minal block.

4. The ground strip has provisions for three ground
leads. The input power, start/stop station, and motor
must be grounded via the ground strip. Two ground
wires must never be inserted in the ground strip under
one screw.

5. If metal conduit is used in place of cable, the
green ground wire from the three phase input power
system is omitted.

SPECIAL THREE PHASE MAGNETIC MOTOR STARTER FOR

OPERATION FROM 575 VOLT THREE PHASE POWER SYSTEMS

Fig. 9, illustrates the special LVC starter which has
been designed for use exclusively on 575 volt, three

phase power systems.

The only difference between the 575 volt three phase

LVC starter and the standard three phase starter,

shown in Fig. 13, is the control transformer.

The control transformer in the standard three phase
starter, shown in Fig. 13, has a multi-tapped primary
which enables the starter to be used from either a

115, 200, 230, 400 or 460 volt three phase power
system. In the special 575 volt three phase starter,
the control transformer has a 575 volt primary so
that the starter will only function from a 575 volt
three phase power system.

The instructions for connecting the power supply to
the special 575 volt starter are identical to the in­structions for connecting the power supply to the
standard three phase motor starter. See instructions
for connecting the power supply to the three phase
motor starter on page 15.

CHANGING V0LTAGE OF LVC MOTOR STARTERS

If it ever becomes necessary to operate a stationary
power tool from a line voltage other than the voltage
for which the tool was originally wired, three steps
must be followed to modify the electrical package for
operation from the new line voltage.

Motor Starter from power source and proceed as fol­lows:

STEP 1 - Remove the motor junction box cover and
change the motor lead connections for the proper line
voltage as shown on the motor nameplate.

Disconnect

STEP 2 - Change the primary of the control trans­former for the proper line voltage, as follows:

The control transformer supplied with all starters,

except the 575 volt three phase starter, has a multi­tapped primary for operation from either a 115, 200,
230, 400 or 460 volt power system.

When changing voltage of an LVC motor starter, the

transformer primary pigtail must be changed corre­sponding to the new input voltage. See Fig. 8.

NOTE:

For 208 volt power systems, connect the

transformer primary to the 200 volt tap, not the 230

volt tap.

Fig 15

Fig 15

16

Fig 16

Fig 17

STEP 3 - Change the heater elements in the overload
block, Fig. 8, for the proper voltage/ampere rating
shown on the motor nameplate.

For every LVC motor starter, a heater coil chart is

located on the inside cover of the motor starter enclo­sure. See Fig. 14.

Note from the motor nameplate, the full load current

for the new line voltage. Select the heater or heaters

one code number lower than specified in the table of

the heater coil chart which will give a maximum trip

rating of approximately 115% of the motor name­plate current.

For example, on three phase starters, assume it is nec­essary to pick a heater for a motor with a nameplate
rating of 10.6 amperes.

Reference to the heater coal
chart in Fig. 14, shows that a 10.6 full load motor
ampere rating corresponds to a heater code number,
E-56. Thus, heater number E-55, should be specified
which will give a maximum trip rating of approxi­mately 1.15 x 10.6 = 12.2 amperes.
