the chuck as shown. Turn the chuck key clockwise to tighten the jaws, and
counterclockwise to open the jaws.
Important Note: Changing the chuck jaws is straight forward, but PARTICULAR
ATTENTION must be given to the sequence in which the jaws are installed. 2. First, remove all 3 jaws from the chuck. This can be done by inserting chuck key
(B) Fig.10 into chuck and turning it counterclockwise. Each jaw will move
towards the edge of the chuck, once they stop moving they can be removed by
hand.
3. Clean the jaws and each chuck slot to make sure there is no debris.
FIGURE 10
4. Locate the slot in the chuck (A) Fig.11 and the jaw (B) with the #1 markings as
shown and rotate the chuck key in the clockwise direction until you see the
beginning of the lead thread (C) on the scroll come into view through the slot,
then back it off slightly until it disappears again. The lead thread is still showing
in the slot in Fig.11. The jaw cannot be loaded until the lead thread for the scroll
is no longer seen in the slot.
5. Slide the #1 jaw into the slot and rotate the key clockwise a couple of turns.
6. Repeat step 5 for jaw #2 and #3 in sequence.
USING THE TAILSTOCk
1. Tailstock handwheel (A) Fig.12. Turning this handwheel moves the tailstock quill
in or out. The graduated dial (B) on the handwheel is adjustable.
2. Quill lock lever (C) Fig.12. This lever locks the tailstock quill.

ADJUSTMENTS & OPERATION
CARRIAGE CONTROLS
Compound Slide
1. The compound slide (A) Fig.14 can be adjusted to produce cuts at an angle
such as tapered cuts. Loosen hex. bolts (B) at the swivel base of the slide,
swivel slide to desired compound angle.
Cross Slide
1. The cross slide (A) Fig.14 moves across the Metal Lathe bed. Turning the cross
slide handwheel (C) clockwise moves the slide away from the operator. The
motion of this slide is used for facing a workpiece and when advancing a cut for
reducing a diameter.
Carriage
1. The longitudinal motion of the carriage (D) Fig.14 is controlled by the lower
handwheel (E) or the handle (F) at the end of the lathe bed. The handwheel will
be used most often, but when the handle is used, remember that the half nut
must be engaged and the handle must be pushed in before it will move the
carriage. The motion of this slide is used when cutting along the length of a
workpiece. This slide can also be operated with the power feed feature.
FIGURE 14
Graduated Dials
1. Each handwheel dial (A) Fig.15 can be rotated without turning the handwheel or
handle. This is helpful because the dial can be set to zero after the tool touches
the part. The graduated dial can be adjusted by holding the handwheel or
handle with one hand and turning the dial with the other.
Carriage Lock
1. The carriage lock lever (A) Fig.16 is located as shown in Fig.16. This allows the
carriage to be locked for precision facing operations while using the lathe or to
make a milling operation more rigid.
FOLLOW REST
FIGURE 15
The follow rest (A) Fig.17 is used on long workpieces supported by a dead centre
mounted in the tailstock. It helps keep deflection to a minimum. The cutter applies
some pressure to the part, in the case of thin parts there is a tendency for the part
to deflect away from the cutter. The follow rest prevents this from happening, the
brass fingers support the workpiece near the point of contact with the cutter.
1. The follow rest (A) Fig.17 gets installed to the leading edge of the carriage as
shown.
2. Loosen the adjusting knobs (B) of each brass finger (C) clockwise until they
stop.
3. Secure the workpiece in the 3-jaw chuck with a dead centre mounted in the
tailstock.
FIGURE 16
4. Lubricate the brass finger (C) surfaces with oil prior to seating them on the
workpiece and occasionally during use.
5. Adjust the brass fingers until they lightly touch the workpiece.
FIGURE 17
STEADY REST
METAL LATHE
ADJUSTMENTS & OPERATION
The steady rest (A) Fig.18 is used the same way as the follow rest. It is also used
to support workpiece when it can’t be supported by the fixed centre in the tailstock.
1. Position the steady rest (A) Fig.18 on the lathe bed in front or behind the
carriage.
2. Place the clamp shoe (B) under the steady rest and secure it using cap screw
(C).
3. Loosen the adjustment knobs (A) Fig.19 for each brass finger (B) and adjust the
brass fingers to allow plenty of clearance for the workpiece.
4. Loosen the knurled knob (C), and pivot the head out of the way.
FIGURE 18
5. Load the workpiece into the chuck as shown.
6. Oil each brass finger, then pivot the head back into place and secure with the
knurled knob (C).
7. Adjust the brass fingers until they lightly touch the workpiece.
METAL LATHE SPEEDS
The speed of the Metal Lathe is controlled by the positions of the V-belts on the
pulleys. The chart in Fig.20 shows the combinations of V-belt positions to achieve
the range of six Metal Lathe speeds.
FIGURE 19
To set speed for Metal Lathe/Changing position of V belts:
1. Unplug the machine from the power source.
2. Loosen the belt tension lock lever (A) Fig.21 on the back of the Metal Lathe belt
guard (B).
FIGURE 20
3. Slide the belt tension lock lever down along the slot so the middle pulley
releases tension on the belts.
FIGURE 21
METAL LATHE
ADJUSTMENTS & OPERATION
METAL LATHE SPEEDS continued...
4. To set the Metal Lathe spindle speed to 160 RPM, move the V-belts (A) Fig.22
to the A and F positions on the pulleys as shown in chart Fig.20.
5. Raise the middle pulley (B) Fig.22 up the slot to retension the V-belts.
6. Tighten the lock lever (A) Fig.21.
7. Check the tension of the V-belts. They should deflect 1⁄2” with moderate finger
pressure applied half way between the pulleys. If more deflection is present,
retension the V-belts as in Step 5. DO NOT over tension the V-belts.
FEED LEVER
The feed lever (A) Fig.23 turns the power feeding feature ON or OFF. When lever
is placed to the right, the feed lever engages power to the leadscrew, providing
power to the carriage and cross slide.
FIGURE 22
When lever is placed to the left as shown, the lever disengages the power feed,
enabling the carriage to be fed manually with the handle at the end of the lathe
bed. The handle cannot be turned manually unless the feed lever is placed to the
left.
FEED SELECTION
WARNING! NEVER MOVE THE FEED SELECTION LEVER WHILE MACHINE IS
RUNNING. SERIOUS DAMAGE WILL OCCUR. STOP MACHINE BEFORE
ADJUSTING FEED SPEED.
WARNING! NEVER FORCE THE FEED SELECTION LEVER, ROTATE CHUCK
BY HAND AND TRY AGAIN.
The feed selection lever (A) Fig.24 controls internal gears that change the feed
rate. The coarsest setting for the feed rate lever is in the “I” position. When the
lever is turned to the “II” position, the feed rate is reduced by one half of the feed
rate of position “I”. When this lever is turned to the “III” position, the feed rate is
reduced by one half the feed rate of position “II”.
FIGURE 23
Refer to Fig.25 for the powerfeed chart. This chart reflects approximate carriage
movement per revolution of the leadscrew. To read this chart:
1. The chart shows the required gears and their position required to accomplish
the available feed rates.
2. The chart shows the available feed rates in millimeters and in inches per
revolution.
3. The chart shows the feed lever position (I, II, III).
Setting a feed rate
FIGURE 24
Selecting gears for a feed rate of 0.002” per revolution:
1. Find 0.002” in the chart in Fig.25.
2. Locate the number in gear position A, which is above 0.002”. The number in this
case is 24, this represents a gear with 24 teeth.
3. Look at the column for the feed lever position and find the roman numeral next
to the 0.002”. In this case III.
4. Change the gears at the B, C, & D locations as necessary (see section
changing gears for more information).
To make a cut using a feed rate of 0.002” per revolution, install the 24 tooth gear
into position A, (see Fig.25) and move the feed selection lever (A) Fig.23 into
position III.
FIGURE 25
METAL LATHE
ADJUSTMENTS & OPERATION
HALF NUT
The half nut lever (A) Fig.26 may be engaged and disengaged while the machine
is running and while making a cut. Move the lever to the up position to engage the
half nut.
Because the threads of the nut and leadscrew will not always be aligned,
engaging the half nut may require waiting until they align, with the machine
running. Lift the lever upwards. DO NOT force the lever, apply light pressure to the
lever and when the threads are aligned the lever will engage.
CARRIAGE POWER FEED
The carriage power feed is designed to aid in cutting threads. Once the proper
gears have been installed, (see section Changing gears) and the feed rate have
been selected, power to the carriage and cross slide is provided by the leadscrew.
1. To activate the carriage power feed, engage the half nut lever (A) Fig.26 by
lifting it upwards.
FIGURE 26
2. To activate the cross slide power feed, pull on ring (B) Fig.26.
WARNING! Do not attempt to engage both the carriage and cross slide power
feeds at the same time, damage to the gears and leadscrew will occur.
CHANGING GEARS
Changing gears is straight forward. Refer to Fig.27 for proper gear selection while
following the example below. We will be changing the gears to those that would be
used to set the machine for a 0.002” per revolution feed rate. These instructions
assume that all of the gears need to be changed. The number of teeth are
stamped on each gear.
FIGURE 27
1. Remove the hex. nuts (A) Fig.28 on the end of the gear shaft of gears A & D.
2. Loosen cap screw (B), at the bottom of the gear support bracket (C) and allow it
to rotate downward.
3. Remove the cap screw (D) Fig.28 in the middle of the gears B/C. This will allow
removal of the gears and rear bushing (A) Fig.31 supporting them. Remove

7. Slide the gears (B) along the slot in the support arm until gear C engages with
gear D, and tighten cap screw (E).
8. Rotate the support arm (A) Fig.32 until gears B and A are engaged. Tighten the
cap screw (B) at the bottom of the gear support arm. Fig.32 shows the gears
properly aligned and engaged.
FIGURE 31
INCH TREADING
The inch threading gear chart is shown in Fig.33. This chart identifies the change
gears needed for cutting threads with inch pitches (TPI).
1. The numbers below A represent the number of teeth on the gears used in gear
position A— in this case 24 or 72 teeth.
2. The column of numbers to the right of D represents the number of teeth on
gears used in gear position D.
3. The column below D represents the feed lever position (I, II or III).
FIGURE 32
4. The gear used in gear position B and C will always be the 120/127 combination
gear. The 127 tooth side will be oriented so it is engaged with the gears in the A
and D position.
5. The remaining numbers represent the range of possible threads per inch (TPI).
Example: If 5 TPI inch threading is desired, set up the change gears as indicated
(120/127, 72, and 30 tooth gear set-up). Refer to Fig.33.
This above set-up has gearing for cutting a 5, 10, or 20 threads per inch (TPI)
screw thread. The feed lever set to the I position will allow 5 TPI. When the feed
lever is set to the II position, 10 TPI will be cut and when set to the III position 20 TPI will be cut.

ADJUSTMENTS & OPERATION
CUTTING THREADS
1. Make sure the thread dial indicator (A) Fig.34 is engaged with the leadscrew. If
not, use a hex. key to loosen the cap screw (B) and rotate the thread dial
indicator until the gear engages with the leadscrew, then tighten the cap screw
to hold the dial in place.
2. Select the RPM you want to use. A slower RPM will give you more time to react
especially if threading over a short distance or threading up to a shoulder.
3. Set the forward/reverse switch for either right or left-handed threads.
4. Examine the thread charts (inch or metric), see Fig.33 or 36, and then set the
gears to the appropriate settings.
5. Turn ON the spindle to verify settings. Check to see that the leadscrew is
turning and verify that the carriage moves in the correct direction by engaging
the half nut lever.
6. Once you are confident the settings are correct, disengage the half nut and turn
OFF the spindle.
7. Examine the thread dial indicator chart in Fig.35 to determine which numbers
(on the thread dial) to engage the half nut.
Note: There are a total of six marks on the thread dial indicator, ranging 1 to 6. To
maintain accuracy and consistency, engage the half nut on the same mark on
each pass. Failure to start on the same number each time may lead to cutting off
the thread made in the previous pass.
FIGURE 34
8. If cutting metric threads, you will not use the thread dial. Once the half nut is
engaged, you must leave it engaged until the threads are complete.
METRIC THREADS (MM)
Refer to metric threading gear chart in Fig.36. The chart lists threads in
millimeters.
1. The numbers to the right of A represent the number of teeth on gears used in
gear position A.
FIGURE 35
2. The column below A represent the feed lever position (I, II or III).
3. All other numbers show the range of possible metric thread pitches.
4. The 120/127 combination gear do not change and will be the intermediate to
gears A and D (24T).
5. Gear D will always have 24 tooth gear installed for metric threading.
FIGURE 36
Example: To cut a thread with a pitch of 1.25 mm. Install 60 tooth gear in position A, install 24 tooth gear in position D and make sure the
120/127 combination gear is installed in the middle. The 60 tooth gear gets engaged with the 127 tooth gear and the 120 tooth gear is
engaged with the 24 tooth gear.

MILL/DRILL SPEEDS
The speed of the Mill/Drill spindle is controlled by two V-belts mounted between
three pulleys. The belts and pulleys are accessed by removing the upper belt
guard as shown in Fig.38.
The spindle speed chart in Fig.39 shows various combinations of V-belt positions
for achieving one of the 16 speeds.
To change belt position (to obtain a spindle speed of 125 RPM):
FIGURE 38
1. Unplug the machine from the power source.
2. Remove the upper belt guard as shown in Fig.38 and loosen both hex. bolts (A).
3. Move the motor assembly (B) to release belt tension. Remove the belts (C) from
their current location and reposition them in the desired positions (to get 125
RPM, set belts in A/E positions as shown in chart Fig.39).
4. Move motor assembly to retension the belts and retightening both hex. bolts (A).
5. Reinstall the upper belt guard.

The height of the Mill/Drill spindle can be locked with the quill lock lever (A) Fig.41.
Set the desired height of the spindle, and then lock the spindle with the quill lock
lever.
FINE DOWNFEED
The up and down motion of the Mill/Drill spindle is controlled by the downfeed
handles (A) Fig.42 just like a drill press. But unlike most drill presses, this machine
is also supplied with a fine feed knob (B).
FIGURE 41
To use this feature, rotate the downfeed handles (A) Fig.42 while pressing the
knob (C) in the center of the hub (D). The knob will engage and the spindle will no
longer move using the downfeed handles. Rotating the fine feed knob (B) in a
clockwise direction will cause the spindle to go down slowly. To disengage this
feature, rotate the fine feed knob and pull on the knob in the center of the hub.
VISE & OPTIONAL ELEVATING BLOCk (kM-124)
This machine comes with a vise (A) Fig.43 that also serves as the compound slide
for Metal Lathe operation. The 4-way tool post and the tool post safety guard must
be removed before using the vise. To open or close the vise jaw, turn handwheel
(B).
An optional Elevating block (A) Fig.44 is available (model KM-124), the vise (A)

REMOVING/INSTALLING CHUCk
MILL/DRILL ADJUSTMENTS,
OPERATION & MAINTENANCE
The Mill/Drill chuck and arbor come installed on the spindle from the factory. To
remove and reinstall the assembly, follow these instructions:
1. Unplug the machine from the power source.
2. Remove the small plastic cap on top of the belt guard as shown. The draw bar
(A) screws into the arbor. Hold onto the outside of the chuck with your free
hand, unscrew the draw bar (A) 3 turns only. Three turns is all that you need,
any more and the threads on the draw bar and the arbor will be damaged when
hitting the end of the draw bar with a rubber mallet. Any less and the arbor does
not have enough room to pop loose from the spindle.
3. Tap the end of the draw bar with a rubber mallet. DO NOT use a steel hammer!
Damage to the draw bar and hammer, such as chipping, may occur.
4. Once the arbor is loose, hold the chuck with one hand and unscrew the arbor
with the other.
5. To reinstall the chuck, first clean the arbor thoroughly. Insert the arbor half way
into the spindle, then quickly slide it in place to seat the two tapers together.
6. Reposition the draw bar (A) Fig.45 and thread it into the arbor. DO NOT over
tighten! The draw bar only needs to be lightly tightened. The taper is what holds
the two parts together, the draw bar just keeps them from chattering loose.

LUBRICATION
This machine will function best when it is clean and well lubricated. Take the time
to wipe down and oil the machine before each use. We recommend using SAE
20W non-detergent oil unless otherwise specified.
Carriage and Cross Slide: Apply lubrication directly to the oil ports of the carriage
and cross slide. See Fig.46.
Motor: The bearings used in the motor are shielded and lubricated for life,
therefore, no lubrication is necessary.
Leadscrew: Be sure to clean and lubricate the leadscrew.
FIGURE 47
Headstock Gearbox: The oil in the headstock should be changed after the first 2
hours of use, then every 6 months, depending on usage. We recommend using a
light weight, non-detergent oil. Viscosity can range from 10W to 30W and may
include multi-viscosity oil in this same range.
To remove the oil in the gear box, remove the change gear directly under the
spindle, remove the cap screw (A) Fig.47, and place a can under the drain hole to
collect the waste oil. Remove oil fill cap (A) Fig.48 and fill gearbox until the oil level
reaches the centre point of the oil level (B).
