Warning

For your own safety, read this instruction manual before operating the lathe.

Wear eye protection.

Do not wear gloves, necktie, or loose clothing.

Tighten all locks before operating.

Rotate the workpiece by hand before applying power.

Rough out the workpiece before installing on the faceplate.

Do not mount a split workpiece or one containing a knot.

Use the lowest speed when starting a new workpiece.

Keep guards in place and in working order.

Remove adjusting keys and wrenches. Form the habit of checking to see that keys and adjusting

wrenches are removed from the tool before turning it on.

Keep the work area clean. Cluttered areas and benches invite accidents.

Do not 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 child proof with padlocks, master switches, or by removing starter keys.

Don’t force the tool. It will do the job better and safer at the rate for which it was designed.

Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry

which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair

covering to contain long hair.

Don’t overreach. Keep proper footing and balance at all times.

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 you product will draw. An

undersize cord will cause a drop in the line voltage resulting in loss of power and overheating. For

runs up to 25 feet, use an 18 AWG or larger gauge cord. For runs up to 50 feet, use a 16 AWG

or larger gauge cord. For runs up to 100 feet, use a 14 AWG or larger gauge cord. For runs up

to 150 feet, use a 12 AWG or larger gauge cord. Runs over 150 feet are not recommended. If in

doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

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.

Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow

instructions for lubricating and changing accessories.

Reduce the risk of unintentional starting. Make sure the switch is in the OFF position before

plugging in the machine.

Use recommended accessories. Consult the owner’s manual for recommended accessories. The

use of improper accessories may cause a risk of injury.

Check damaged parts. Before further use of the tool, 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.

Direction of feed. Feed work into a blade or cutter only against the direction of rotation of the blade

or cutter.

Give your work undivided attention. Looking around, carrying on a conversation and “horse-play”

are careless acts that can result in serious injury.

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.

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.

Do not operate this lathe while tired or under the influence of drugs, alcohol or any medication.

Turn off the tool and disconnect from power before cleaning. Use a brush or compressed air to

remove chips or debris — do not use your hands.

Never leave the tool running unattended. Turn the power off and do not leave the tool until it

comes to a complete stop.

Electrical Requirements

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric

current to reduce the risk of electric shock. This tool is equipped with an electric cord having an

equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet

that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified

electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The

conductor, with insulation having an outer surface that is green with or without yellow stripes, is the

equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not

connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely

understood, or if in doubt as to whether the tool is properly grounded.

Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles

that accept the tool’s plug.*

Repair or replace a damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet that looks the one illustrated in Figure A below.

The tool has a grounding plug that looks like the grounding plug as illustrated in Figure A below. A

temporary adapter, which looks like the adapter as illustrated in Figure B below, may be used to connect

this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet is not available.**

The temporary adapter should only be used until a properly grounded outlet can be installed by a

qualified electrician. The green colored rigid ear or tab, extending from the adapter, must be connected to

a permanent ground such as a properly grounded outlet box.

* Canadian electrical codes require extension cords to be certified SJT type or better.

** Use of an adapter in Canada is not acceptable.

2. Inspect contents for shipping damage and

report damage, if any, to your distributor.

3. Be sure to keep the box and packing

material should you need to pack the lathe

for moving.

4. Do not clean the lathe with anything other

than a damp cloth or a mild solvent. Use of

heavy solvents, paint thinner, gasoline, etc.

Assembly

The JML-1014I is fully assembled and comes

ready to use right out of the box. However, it is a

good practice to thoroughly check the machine

for loose fasteners, handles, etc. before use.

The JWL-1220 requires minor assembly: Install

the tool caddy using the two pan head screws,

as shown in Figure 1. The JWL-1220 is provided

with a lifting handle on each end. These can be

pushed in when not in use.

If desired, the lathe can be bolted to a work

table or stand by removing the rubber feet and

inserting screws through the holes in the base.

IMPORTANT: The table or stand should have

an opening directly beneath the motor to prevent

build-up of shavings around the motor’s fan

housing.

Figure 1 – Model JWL-1220 only

A stand specifically made for the lathe is

available from WMH Tool Group. See stock

numbers on page 6 for ordering.

Operations

Tailstock Movement

Tailstock Handwheel (A, Figure 2) – Turn

clockwise to move tailstock spindle forward.

Turn counterclockwise to retract tailstock

spindle.

Tailstock Spindle Lock (B, Figure 2) – Locks

tailstock spindle. Release to adjust with

handwheel.

Tailstock Lock (C, Figure 2) – Locks tailstock in

position on the bed. Release to move the

tailstock assembly closer to or farther from the

headstock.

Figure 2

The tailstock spindle is hollow. This can be

useful for inserting a long bit to drill a hole in the

center of a workpiece on the face plate.

The clamping device on the tailstock has been

factory adjusted; however, if further adjustment

should be needed, slide the tailstock off the end

of the bed, and tighten or loosen the nut (D,

Figure 3) beneath the tailstock.

On/Off Switch

The switch, shown in Figure 4, has a safety

feature to prevent unauthorized use; pull out the

upper piece of the switch and store in a safe

place. The piece must be re-inserted to operate

the lathe.

Figure 3

Work Lamp (JWL-1220 only)

The 20” lathe is provided with a flexible work

lamp which uses a 40-watt bulb (not provided).

Position the work lamp so that wood chips

do not accumulate inside the lamp shade

and pose a fire hazard.

Use only a 40-watt or smaller

bulb in the work lamp.

Figure 4

Spur Center (Figure 5)

–

Slides into

headstock and holds the workpiece during

spindle turning.

Thoroughly clean the taper

on the spur center and the inside of the

headstock spindle before mounting the spur

center. Failure to do so may result in

separation of the two and possible injury or

tool damage.

Face Plate (Figure 6) – Screws on to the

headstock and is used in face plate turning

operations. Mount your workpiece onto the

faceplate with brass screws (not provided).

Make sure the screws are not so long that they

will enter the area of the workpiece where the

material is to be removed.

To remove the face plate from the spindle, place

the drift rod into hole (A, Figure 6) and let the

drift rod contact the bed of the lathe for

leverage. Then unscrew the face plate.

Drift Rod (Figure 7) – Slides into the

headstock to tap the spur center free. Stored in

the hole in the base below the headstock (JML-

Figure 6

1014I) or in the tool caddy (JWL-1220).

NOTE: Always hold on to the spur center while

tapping it free, to prevent it from falling.

Tool Rest (Figure 8) – Attaches to the bed.

Used to steady the cutting tool during spindle

turning or face plate operations.

Adjusting the Tool Rest

Position the tool rest (Figure 8) as close to the

workpiece as possible. It should be 1/8” above

the centerline of the workpiece.

Figure 7

Position the tool rest base on the bed by

releasing the locking rod (A, Figure 8) and

sliding base to the desired position. Tighten

locking rod to fix the position of the tool rest

base.

Adjust the height of the tool rest by loosening

the handle (B, Figure 8) and raising or lowering

tool rest.

Should adjustment of the tool rest clamping

device become necessary, turn off the machine,

reach under the bed, and adjust the clamping

nut.

NOTE: The lock handles (B, Figure 2 and B,

Figure 8 for example) are adjustable. Simply pull

up on the handle, rotate it on the pin, and then

release. Make sure the handle seats itself

properly upon the pin.

Figure 8

5. Loosen the two set screws in handwheel (G,

Figure 10). Unscrew the handwheel while

holding the spindle stationary.

6. Remove handwheel and pull the spindle out

while holding onto the spindle pulley.

Figure 11

7. Place the new belt on the spindle pulley.

Place the spindle pulley back into the

headstock the same way it was removed.

8. Insert the spindle into the spindle pulley

aligning the key.

9. Thread the handwheel onto the spindle

leaving

little space between the

handwheel and headstock. Tighten set

screws (G, Figure 10).

10. Center the spindle pulley and tighten set

screw (F, Figure 10).

11. Wrap the belt around the motor (lower)

pulley. Be sure the belt is aligned with

spindle pulley and motor pulley.

12. Tension the belt and tighten the motor plate

lock handle (C, Figure 11).

Removing and Installing Live Center

1. Loosen tailstock lock handle (B, Figure 12).

2. Turn the tailstock handwheel (A, Figure 12)

counterclockwise until the live center (C,

Figure 12) ejects from the spindle. NOTE:

Do not allow the live center to fall.

3. Before installing the live center into the

spindle, the spindle must be extended out

from the tailstock body far enough to allow

the live center to “seat” in the spindle.

Index Pin

The index feature allows you to cut evenly

spaced features in a workpiece while keeping

the Lathe headstock spindle locked; for

example, when cutting flutes on a spindle blank

with a router, while the spindle blank is secured

within the Lathe centers. There are 24 index

positions on the lathe.

1. To use the index pin (Figure 13), screw it

farther into the headstock until it engages a

hole in the spindle pulley.

2. Make your first flute cutting.

Figure 13

3. Unscrew the index pin just enough so that it

frees the spindle. Carefully rotate the

spindle to the next index position. (If you

push inward on the index pin while rotating

the spindle, you can feel when it tries to

enter the next index position.)

4. Screw in the index pin completely and

perform the second flute cutting.

NOTE: Back out the index pin completely to

free the spindle before turning on the lathe.

Maintenance

Disconnect machine from power source before

performing any maintenance.

Blow out dust and accumulation inside the

motor, the housing and the bed assembly

frequently. If the tailstock has been used as a

guide for drilling through the center of a

workpiece, also blow sawdust or shavings out of

the center of both spindles.

A coat of paste wax applied to the bed will help

keep the surface clean and maintain smooth

movement of the tool rest and tailstock.
