9. USE PROPER EXTENSION CORD. Make

sure your extension cord is in good condi-

tion. Conductor size should be in accor-

dance with the chart below. The amperage

rating should be listed on the motor or tool

nameplate. An undersized cord will cause a

drop in line voltage resulting in loss of

power and overheating. Your extension

cord must also contain a ground wire and

plug pin. Always repair or replace exten-

sion cords if they become damaged.

13. DON’T OVERREACH. Keep proper foot-

ing and balance at all times.

14. MAINTAIN TOOLS WITH CARE. Keep

tools sharp and clean for best and safest

performance. Follow instructions for lubri-

cating and changing accessories.

and that the lathe sits on a flat, stable sur-

face.

9. NEVER OPERATE THE LATHE WITH

DAMAGED OR WORN PARTS. Maintain

your lathe in proper working condition.

Perform routine inspections and mainte-

nance promptly when called for. Put away

adjustment tools after use.

2. BEFORE STARTING THE MACHINE be

certain the workpiece has been properly

engaged in the chuck and tailstock center

(if in use) and that there is adequate

clearance for full rotation.

10. MAKE SURE YOUR METAL LATHE IS

TURNED OFF, disconnected from its

power source and all moving parts have

come to a complete stop before starting

any inspection, adjustment, or mainte-

nance procedure.

3. ADJUST TOOL HOLDER to provide prop-

er support for the turning tool you will be

using. Test tool holder clearance by rotat-

ing workpiece by hand before turning lathe

on.

11. KEEP LOOSE CLOTHING ARTICLES

such as sleeves, belts or jewelry items

away from the lathe spindle.

4. SELECT THE TURNING SPEED which is

appropriate for the type of work and the

type of material. Allow the lathe to gain its

full speed before beginning turning.

12. ALWAYS USE THE PROPER CUTTING

TOOLS for the material you are turning,

make certain they are sharp and that they

are held firmly in the tool holder.

5. NEVER CHANGE FEED RATE or spindle

speeds while the lathe is turning.

13. ALWAYS PLACE A BOARD OR PIECE

OF PLYWOOD ACROSS THE BEDWAY

when removing or installing chucks to

avoid the possibility of a finger pinch point

occurring between a loose chuck and the

edges of the bedway.

6. NEVER REVERSE MOTOR DIRECTION

SECTION 2: CIRCUIT REQUIREMENTS

220V Operation

Grounding

The Model G4002/3 is wired for 220 volt, single

phase operation. The 2 HP motor will safely draw

9 amps at 220V. A 10-amp fuse or circuit break-

er should be used when connecting this metal

lathe. Circuits rated any higher are not adequate

to protect the motor.

In the event of an electrical short, grounding

reduces the risk of electric shock by providing a

path of least resistance to disperse electric cur-

rent. This tool is equipped with a power cord hav-

ing an equipment-grounding conductor. See

Figure 1. The outlet must be properly installed

and grounded in accordance with all local codes

and ordinances.

If you operate this lathe on any circuit that is

already close to its capacity, it might blow a fuse

or trip a circuit breaker. However, if an unusual

load does not exist and a power failure still

occurs, contact a qualified electrician or our ser-

vice department.

This equipment must be grounded. Verify

that any existing electrical outlet and circuit

you intend to plug into is actually ground-

ed. If it is not, it will be necessary to run a

separate 12 A.W.G. copper grounding wire

from the outlet to a known ground. Under

no circumstances should the grounding pin

from any three-pronged plug be removed.

Serious injury may occur.

Equipment returned to us for service that shows

evidence of being over-fused will be repaired or

replaced totally at the customer’s expense,

regardless of the present warranty status.

Extension Cords

If you find it necessary to use an extension cord

with the Model G4002/3, make sure the cord is

rated Hard Service (grade S) or better. Refer to

the chart in the standard safety instructions to

determine the minimum gauge for the extension

cord. The extension cord must also contain a

ground wire and plug pin. Always repair or

replace extension cords when they become worn

or damaged.

Site Considerations

Clean Up

1. Floor Load: The Model G4002/3 can be

mounted on your existing workbench or on

an optional cabinet stand which is listed in

our current Grizzly catalog. If you choose to

use the stand, you will find the holes for bolt-

ing the G4002/3 to the stand are already in

place. If you are using your own bench,

ensure that it is strong enough to handle the

weight of the G4002/3 lathe. Keep in mind,

whichever way you choose to mount the

lathe, it’s essential that the mounting surface

be perfectly flat. Use an accurate carpenter’s

level to ensure that your bench is properly

leveled.

The unpainted surfaces are coated with a waxy

oil to protect them from corrosion during ship-

ment. Remove this protective coating with a sol-

vent cleaner or citrus-based degreaser, like

Grizzly’s G7895 Citrus Engine Degreaser. Avoid

chlorine-based solvents as they may damage

painted surfaces should they come in contact.

Always follow the usage instructions on the prod-

uct you choose for clean up.

Many of the solvents commonly used to

clean machinery can be highly flammable,

and toxic when inhaled or ingested. Always

work in well-ventilated areas far from

potential ignition sources when dealing

with solvents. Use care when disposing of

waste rags and towels to be sure they do

not create fire or environmental hazards.

Keep children and animals safely away

when cleaning and assembling this

machine.

2. Working Clearances: Consider existing and

anticipated needs, size of material to be

processed through each machine, and

space for auxiliary stands, work tables or

other machinery when establishing a loca-

tion for your lathe.

3. Lighting and Outlets: Lighting should be

bright enough to eliminate shadow and pre-

vent eye strain. Electrical circuits should be

dedicated or large enough to handle amper-

age requirements. Outlets should be located

near each machine so power or extension

cords are clear of high-traffic areas. Observe

local electrical codes for proper installation

of new lighting, outlets, or circuits.

Do not use gasoline or other petroleum-

based solvents to remove this protective

coating. These products generally have low

flash points which makes them extremely

flammable. A risk of explosion and burning

exists if these products are used. Serious

personal injury may occur.

All die-cut metal parts have a sharp edge

(called “flashing”) on them after they are

formed. This is generally removed at the

factory. Sometimes a bit of flashing might

escape inspection, and the sharp edge may

cause cuts or lacerations when handled.

Please examine the edges of all die-cut

metal parts and file or sand the edge to

remove the flashing before handling.

Make your shop “child safe”. Ensure that

your workplace is inaccessible to young-

sters by closing and locking all entrances

when you are away. Never allow visitors in

your shop when assembling, adjusting or

operating equipment.

SECTION 4: ASSEMBLY & SETUP

Chucks

Mounting

The Model G4002/3 Metal Lathe comes equipped

with a 6'' 3-jaw chuck (already installed), a 8'' 4-

jaw chuck and a face plate.

This lathe should be securely mounted to a stand

or bench top. An accessory stand is available

from Grizzly, please see our current catalog for

pricing. There are 2 holes in the base at the tail-

stock end of the lathe and four holes on the gear-

head end which can be used to secure the

machine to a stand.

The 3-jaw chuck is a scroll-type chuck, meaning

that all three jaws move in unison when adjust-

ments are made. The 4-jaw chuck, on the other

hand, features independent jaws. The 4-jaw

chuck is used for square or unevenly-shaped

stock.

The lathe does not require a great deal of assem-

bly. This section details the installation of the var-

ious accessory holding devices. The following

section will familiarize you with the controls for

your new lathe. After you have completed both of

these sections we will do a test run of the

machine. Do not attempt a test run until you have

become familiar with both of these sections.

The 3 and 4-jaw chucks have a D-1 Camlock

mount. Please note that there are lines stamped

into the cam and on the chuck body. A chuck key

is used to turn the locking cams as in Figure 2.

DO NOT attempt to start this machine until

you have completed all of the assembly and

control familiarization steps. When per-

forming the assembly steps, ensure that

the switch is off and the power is discon-

nected. Failure to comply with this could

cause inadvertent starting of the machine

which can result in serious operator injury.

Figure 2. Key positioned to remove chuck.

Lubrication

The G4002/3 is shipped from the factory pre-

lubricated. However, it is recommended that you

go through the entire lubrication sequence before

operating the machine. Review Section 7:

Maintenance for lubrication instructions.

Lubrication must be completed before you

start your new lathe.

ALWAYS place a piece of plywood over the

ways of the lathe before removing or

installing a chuck. This helps by covering

the sharp corners of the bed, protecting

your hands and fingers. Use extreme care

when removing or installing a chuck so

that your hands do not become trapped

between the chuck and the plywood.

G4002/3 Gear Head Lathes

To remove a chuck:

3. Turn the other cams in the same way. Make

sure to support the chuck with one hand as

you align the last cam. The chuck may

come off at this point so it is important you

are ready to support its weight.

1. Place a piece of plywood across the lathe

bed and position it just under the chuck.

The board should be at least 8" wide and

10" long.

4. Remove the chuck key.

If the chuck is still tight on the spindle:

Tap the back of the chuck with a rubber or wood-

en mallet while supporting the bottom of the

chuck with your free hand. If the chuck does not

immediately come off, rotate the spindle approxi-

mately 60˚ and tap again. Make sure all the

marks on the cams and spindle are in proper

alignment.

Never leave a chuck key in the chuck when

it is not in use. If the machine is acciden-

tally started with this in place, it can

become a projectile and cause serious

injury.

To install a chuck:

1. Place a piece of plywood across the lathe

bed and position it just under the spindle.

2. Lift the chuck up to the spindle and align

the pins in the back with the holes on the

spindle’s face and insert the pins.

3. While supporting the weight of the chuck,

turn one cam with the chuck key until the

cam line is between the two vees on the

spindle. Do not tighten at this time.

4. Rotate the spindle and repeat step 3 on the

Figure 3. Cam lines aligned to spindle line.

last two cams.

2. Turn a cam, with the chuck key, in the lathe

spindle in a counter-clockwise rotation until

the line on the cam is aligned with the line

going across the spindle housing as in

Figure 3.

5. Return to the first cam and snug it up.

Repeat with the rest of the cams.

6. Finally, tighten all three cams.

The chuck is heavy and can be awkward to

handle. Be aware that when removing or

installing a chuck a finger pinch situation

exists.

Steady Rest

Live Center

The live center is used to support stock which is

too long to be supported by the chuck alone.

Stock protruding more than three times its diam-

eter should be supported by the live center.

The steady rest supports long, small diameter

stock that otherwise could not be turned. The

steady rest can also replace the tailstock to allow

for cutting tool access at the outboard end of your

workpiece.

To mount the steady rest:

1. Secure to bedway from below with the lock-

ing plate.

2. A single hex bolt, along with a nut and

washer, is used to hold the steady rest in

place. See Figure 5.

3. The bearing surfaces on the steady rest

should receive periodic lubrication while in

use to prevent premature wear.

Figure 4. Live center installed in tailstock.

The tailstock barrel and live center have a Morse

taper #3. Before assembling these, insure that

the mating surfaces are “white glove” clean.

These parts will last longer and remain accurate

when properly maintained. Morse tapers will not

interlock when oil is present on the mounting sur-

faces. Insert the end of the live center into the tail-

stock bore until it seats. The force of a mounted

workpiece will fully seat the taper.

When using a live center, the tailstock barrel

should protrude about ⁄2'' and not more than 3''.

See Figure 4.

Figure 5. Steady rest in place.

To remove the live center, back the tailstock bar-

rel all the way into the tailstock casting. The live

center will pop out. Be sure to catch it when it

comes out to avoid damaging the tip.

2. Mount the back plate on the spindle.

Follow Rest

3. Accurately measure the inside of the back

relief bore on the 4-jaw chuck. This

dimension is critical, .001''.

The follow rest is normally used with small diam-

eter stock to prevent the workpiece from “spring-

ing” under pressure from the turning tool. To

install the follow rest:

4. Face the back plate to true it. Make pass-

es across the face until its entire surface

has been cut.

1. The follow rest is secured to the saddle with

two cap screws. See Figure 6.

5. Turn a shoulder into the face ¹⁄8'' deep and

.001" to .002'' larger than the back relief

bore diameter. Chamfer the corner a

small amount.

2. The bearing surfaces on the follow rest are

similar to those on the steady rest, and

should be lubricated to prevent premature

wear.

6. Set the chuck on the back plate aligning

the shoulder with the relief bore. Use a

transfer punch to mark the back plate. If a

transfer punch is not available, a drill bit of

the same size as the mounting holes in

the chuck can be used. Lightly tap on the

bit, rotate it 90° and tap it again.

7. Remove the chuck from the back plate

and center punch the marks. Drill and tap

the holes for ³⁄8''-16.

8. Set the chuck on the back plate. Line up

the mounting holes and thread in the cap

screws supplied. Remember that this is a

.001" to .002" press fit. Snug up the first

cap screw then alternate to the cap screw

across the chuck. Alternating the tighten-

ing process insures the chuck will go on

straight. This step should be repeated

until the back plate fits snugly against the

chuck. If the chuck fits loosely on the back

plate, or is crooked on the shoulder, it will

be necessary to face and shoulder the

back plate again.

Figure 6. Follow rest secured to saddle.

4-Jaw Chuck

The 4-jaw chuck supplied with the G4002/3 is not

mounted to the back plate. Assembly of the back

plate components is also required.

1. Make note of the reference lines on each

of the 3-jaw chuck studs. Thread each of

the 4-jaw chuck cam lock studs into the 4-

jaw chuck back plate to the exact same

depth as the 3-jaw studs. Screw in the

locking cap screws.

SECTION 5: CONTROLS

Spindle Speeds

Never change speeds while spindle or motor

is in motion.

The speed of the spindle is controlled by the

positions of the speed control knobs. See Figure

7. By positioning the knobs using the chart in

Figure 8, you can achieve all of these speed

ranges: 70, 200, 220, 270, 360, 600, 800, 1000

and 1400 RPM.

Figure 8. Speed chart.

The chart above shows the various combinations

of knob positions for achieving a desired speed.

Example:

To select a spindle speed of 600 RPM, move the

left-hand selector knob until the indicator arrow

on its hub is pointing to the “C”. Move the right-

hand selector knob until its indicator arrow is

pointed at the “3”.

Feed Direction

Selecting the Feed Rod

Never move selection levers while machine is

running.

The feed rod can be selected by rotating the han-

dle to the left as in Figure 10. Use this position for

all feeding operations. When the lever is posi-

tioned straight up, no drive device is selected and

the gear train is in neutral after this point.

The G4002/3 Metal Lathe can cut left or right while

feeding or threading and across both ways for fac-

ing operations. This feed direction is controlled by

the selection knob as shown in Figure 9.

Figure 10. Feed rod selected.

Figure 9. Directional control lever.

Quick Change Selection

When the selection knob is positioned as depict-

ed in Figure 9, the apron will move to the right

along the bed or the cross feed will travel away

from the operator. The cross feed and longitudi-

nal feed selection is controlled on the apron and

will be discussed later.

The two levers at the bottom of the headstock

change the feed rate, or the number of threads-

per-inch. This section of the machine is com-

monly known as the Quick Change Gear Box.

See Figure 11. The left-hand lever can be

engaged in any of five different positions and are

listed on the charts as A, B, C, D, and E. The

right-hand lever has 8 positions and are listed on

the charts as 1 through 8.

To reverse the direction of the feeding or thread-

ing operation, rotate the selection knob to the

right. It should be noted that when the lever is

positioned in the middle, no direction is selected

and all of the drive mechanisms after this point

are in neutral.

The machine label describes some of the more

typical settings which might be used. Figure 12

shows the feed rate chart located on the gear

cover of the lathe. The chart is divided into met-

ric feed rates and inch feed rates.

Important:

Do not force any selection lever on the machine.

If the lever will not engage, rotate the chuck by

hand while keeping light pressure on the selec-

tor. As the chuck rotates it aligns the gears and

the selector will engage.

Important:

Do not force any selection lever on the machine. If

the lever will not engage, rotate the chuck by hand

while keeping light pressure on the selector. As the

chuck rotates, it aligns the gears and the selector

will engage.

Figure 12. Feed rate selection.

This symbol indicates longitudinal feed.

This symbol indicates cross feed rates.

To change the position of the feed selector, pull the

knurled handle. This disengages a pin which is

inserted into a selection hole. Position the lever in

the down position and slide to the right or left until

it is positioned below the desired selection hole.

Raise the lever with one hand while pulling the

handle with the other. The pin at the end of the

lever should align with the selection hole. If it does

not, rotate the feed rod or chuck by hand while

maintaining gentle pressure on the lever.

Feed Lever - Longitudinal and cross slide pow-

ered motions are controlled by the feed lever.

The lever pivots through two stops which require

moving the lever left and right as well as up and

down. Moving this lever upward activates the

automatic longitudinal feed. Moving the lever

down activates the cross slide. See Figure 13.

Feed Rate Chart

To perform a longitudinal cut in inches, use the

bottom portion of the chart. If the desired feed

rate is 0.0062"/revolution, look at the longitudinal

ranges. According to the chart we would put the

left-hand lever in the “C” position and the right-

hand lever in the “4” position. Metric calculations

would be done the same way. To perform a cross

feed cut with a feed rate of 0.0013" move the left-

hand lever to the “D” position and the right-hand

lever to the “1” position.

Please note that when either of the two selector

levers are left in the down position, the drive train

after this point is in neutral.

While other thread pitches may be achieved, the

G4002/3 comes with a chart that requires no gear

changes for cutting inch threads.

Thread Selection

To achieve a desired thread pitch in inches, it is

necessary to determine the quick-change lever

positions. Refer to Figure 15 and find the desired

thread.

Inch thread selection:

To cut threads with inch pitches, a selection must

be made for feed direction, pitch and lead screw.

Example:

Select the desired direction of cut as described in

the section titled Feed Direction.

The thread to be cut has 20 threads per inch

(TPI). Looking at the chart we find that the left

hand lever would be positioned at “C”. The right

hand lever would be positioned at “4”.

Rotate the Feed/Lead Screw selection lever to

the position shown in Figure 14. If the lever does

not readily engage, rotate the lead screw or the

chuck by hand while maintaining gentle pressure

on the lever.

These rest in a housing that pivots so that the

gear can be engaged or disengaged. An Allen^®

head cap screw is located on the side of the

housing. Loosen this screw to change the posi-

tioning of this housing.

NOTICE

The threading dial cannot be used when cut-

ting metric threads. Once the half nut has been

engaged, it must remain engaged throughout

the threading process.

When engaged, the dial will turn when the spin-

dle is turning. If the dial does not turn, readjust

the housing.

Half Nut Lever - This lever compresses and

releases the half nut that engages the leadscrew.

See Figure 16. The lever is only engaged while

turning threads in stock. A lockout device fea-

tured in the lever mechanism engages when the

feed selector is used.

When the half nut is engaged the dial stops turn-

ing. By carefully engaging the half nut as the

appropriate line or number passes by the indica-

tor mark, a thread can be established and the

lead maintained through the multiple passes that

are required to cut a thread to the finished depth.

The chart listed in Figure 16b shows a system

for using the threading dial indicator while cutting

inch threads.

NOTICE

Do not simultaneously engage the feed lever

and the threading lever. Doing so will damage

the lathe.

Example:

To cut 11 threads per inch engage the half nut

when the 1 or the 3 is on the indicator mark.

Determine the length of the thread to be cut.

Make a cut along the part and disengage the half

nut. Return the carriage to the beginning of the

cut. Watch the dial and when the 1 or the 3

comes around to the indicator mark engage the

half nut. Repeat this process until the desired

depth of cut has been achieved.

Dial

Threading Dial Indicator - The indicator tells

you when to engage the half nut to begin the

threading process. See Figure 16.

The Threading Dial Indicator has 8 lines and four

numbers printed on the dial. An indicator mark is

positioned near the rim of the dial. The dial is

mounted on a shaft that has a worm gear mount-

ed at its opposite end.

3. To the left of the desired pitch is a small

column with a letter. This letter indicates

placement of the left hand quick change

lever. Move the lever to the corresponding

location.

Metric thread selection:

The chart in Figure 17 lists 29 metric threads

that can be cut on the G4002/3. Five ranges are

used on the left hand quick change selector and

6 on the right hand quick change selector.

Additionally, 5 gear changes are necessary to

accomplish all of the available metric threads.

These gear changes take place on the left hand

end of the machine. See Figure 18.

4. In the “Combination of Gears” column are 3

small columns. Please note the “F” and “G”

at the top. The numbers below F and G

represent the number of gear teeth of a

gear included with the lathe. Find the gears

that have the corresponding number of

teeth as stated in the chart to the left of the

desired pitch.

The chart is divided into 3 main sections or

columns. Starting from the left: Gear diagram,

Combination of Gears and ^m/m Per Pitch.

Example:

To use the chart:

The desired metric pitch is 1.25 mm. Find this

number in the chart and find the number of teeth

of the two gears to the left. The F gear will need

to have 47 teeth and the G will need 60 teeth. A

diagram on the left side of the chart on the

machine tells us the 47 tooth gear goes on top of

the middle gear and the 60 tooth gear goes on

the bottom.

Find the desired pitch in the chart.

2. Below the ^m/m Per Pitch label are numbers.

Find the corresponding number above the

desired pitch and change the right hand

quick change lever to that position.

Cross Slide Handwheel - The Cross Slide

Handwheel moves the top slide toward and away

from the work. Turning the dial clockwise moves

the slide toward the workpiece. The graduated

dial can be adjusted by holding the handwheel

with one hand and turning the dial with the other.

Carriage Controls

The carriage handwheel allows the cutting tool to

move along the length of the lathe bed. The

cross slide allows the cutting tool to travel per-

pendicular to the bed. The carriage features a top

slide which allows linear movement of the cutting

tool at any preset angle. This section will review

the individual controls on the carriage and pro-

vide descriptions of their uses. See Figure 20.

Carriage Handwheel

The Longitudinal

Handwheel moves the carriage left or right along

the bed. The control is helpful when setting up the

machine for turning or when manual movement is

desired during turning operations.

Compound Slide Handwheel - The Top Slide

Handwheel controls the position of the cutting

tool relative to the workpiece. The top slide is

adjustable for any angle. The graduated dial is

adjustable using the same method as the dial on

the cross slide. Angle adjustment is controlled by

hex nuts on the base of the top slide.

Tailstock Controls

Tool Post and Holder

The tailstock serves many functions. The prima-

ry use is for holding centers and drill chucks. The

barrel has a Morse taper ^#3 bore and is imprinted

with graduations in millimeters and inches.

Please refer to Figure 23.

Tool post - A quick change tool post and 2 tool

holders are supplied with the Model G4002/3.

Figure 22 shows tool post and a holder with

optional bit. Cutting tools can be secured and

removed by tightening or loosening the clamping

screws in the top of the holder. A threaded stud

is mounted in the top of the holder and has a

knurled thumb wheel. Rotating the thumb wheel

allows for adjustment of the tool holder so the

cutting tool can be centered. The handle on the

tool post can be rotated to lock and unlock the

tool holder onto the dovetail ways. The tool post

may be rotated by loosening the nut at the top of

the tool post.

Tailstock Handwheel - Turning the handwheel

advances or retracts the barrel in the tailstock.

The graduated dial on the handwheel is

adjustable.

If the direction is reversed, contact our service depart-

ment for further instructions.

Test Run

5. If the lathe is running correctly, lift the spindle con-

trol lever to the neutral position, wait for the

machine to come to a complete stop and take

some time to become familiar with the various

controls.

Always make sure the power switch is in the

“OFF” position and the spindle control lever

is in the neutral position before plugging in

power cord.

Now that the lathe is securely in place and

you’ve read the safety guidelines, it’s time to give

the machine a test run.

Before starting the machine:

1. Make sure the machine is properly ground-

ed, the Power Switch is in the “OFF” position

and the spindle control lever is in the neutral

position. See Figure 24.

2. Inspect the machine to ensure that all hand

tools are out of the way, guards are in place

and nothing is impeding the movement of

the chuck. Check this by rotating the chuck

by hand.

Figure 24. Carriage control lever in neutral.

3. Rotate the stop switch, on the headstock of

the lathe, in the direction indicated by the

arrows imprinted on the button.

4. Lower the control lever on the apron. The

spindle should start turning in a counter

clockwise direction.

SECTION 6: ADJUSTMENTS

Gibs

There are three main gib adjustments for the

Model G4002/3. They are: the cross-slide gib, the

compound slide gib and the saddle gib.

Cross-slide Gib - The gib on the cross-slide is

adjusted by the two screws located at each end.

See Figure 25. To adjust, loosen the setscrew

located along the edge of the cross-slide.

This setscrew is provided for locking the slide for

certain operations. After making the adjustments

detailed below, tighten the setscrew until it just

Figure 25.Adjusting the cross-slide gib.

touches the gib.

The gib is wedge shaped and by loosening the

screw closest to the operator and then tightening

the opposite screw, the slide will become looser.

Conversely, loosening the screw furthest away

from the operator and tightening the closer screw

will tighten the gib. Do not over tighten. Adjust the

gib so that it creates a slight drag when the slide

is in motion. Test the ease of motion with the gib

slightly loose. Begin tightening the gib and test

after making small adjustments. When a slight

drag is detected the gib is properly adjusted.

Compound Gib - The gib on the compound is

adjusted by the same method as the gibs on the

cross-slide, except the screw closest to the oper-

ator (when the compound slide is aligned with the

cross slide) must be loosened and the screw fur-

thest from the operator tightened to make the gib

tighter. See Figure 26.

NOTICE

When adjusting gibs, keep in mind that the

goal of gib adjustment is to remove unneces-

sary sloppiness from the slide’s movement

without causing them to bind. Loose gibs may

cause poor finishes on the workpiece. Over

tightening may cause premature wear.

Figure 26. Tightening this screw tightens gib.

Download from Www.Somanuals.com. All Manuals Search And Download.

Saddle Gib - The saddle is supplied with a

square head bolt on the front right hand side of

the slide. Before making adjustments to the sad-

dle gib, ensure that this bolt is loose by turning it

counter clockwise. See Figure 26b.

Steady/Follow Rest

To adjust the Steady Rest:

It is important that the apron gib be properly

adjusted. A loose gib will cause finish problems

in a workpiece. A gib adjusted too tightly will

cause premature wear.

1. Loosen the lock nuts. See Figure 27.

2. Open the sliding fingers by turning the

knurled screws until they fit around the

workpiece. Secure the steady rest in posi-

tion.

The gib for the saddle is located on the bottom

of the back edge of the slide. The tension on this

gib is maintained by four setscrews with jam

nuts. By loosening the jam nuts and tightening

the setscrews, the gib will tighten. Loosening the

setscrews will loosen the gib. The gib strip is

properly adjusted when a slight drag is detected

while moving the apron. Do not over tighten.

3. Tighten the knurled screws so that the fin-

gers are snug, but not tight against the

workpiece. Tighten the setscrews and the

lock nuts.

4. Lubricate the brass points with machine oil.

It is important the 4 setscrews are tightened

evenly. When tightening the jam nuts, hold the

setscrew’s position using an Allen^®wrench.

The Follow Rest is setup in the same manner

except that the place of the third finger is taken up

by the tool bit. The follow rest prevents long,

small diameter pieces from flexing under the cut-

ting pressure from the tool bit.

Tailstock

The tailstock on the Model G4002/3 is aligned at

the factory with the headstock. It is recommend-

ed that you take the time to ensure that the tail-

stock is aligned to your own desired tolerances.

To align the tailstock:

1. Center drill a 6'' long piece of bar stock on

both ends. Set it aside for use in step 4.

2. Make a dead center by turning a shoulder

to make a shank. Flip the piece over in the

chuck and turn a 60° point. See Figure 28.

As long as it remains in the chuck, the point

of your center will be accurate to your spin-

dle’s axis. Keep in mind that the point will

have to be refinished whenever it is

removed and returned to the chuck.

Figure 29. Bar stock mounted on centers.

TIP

Before making adjustments to the tailstock,

mount a dial indicator so that the dial’s plunger

is on the tailstock barrel. See Figure 30.

Viewed from above.

Figure 28. Finished dead center.

Figure 30. Adjusting for headstock end taper.

3. Place the live center in your tailstock.

6. Measure the stock with a micrometer. If the

stock is fat at the tailstock end, the tailstock

needs to be moved toward you the amount

of the taper. See Figure 30.

4. Attach a lathe dog to the bar stock and

mount it between the centers. See Figure

29.

5. Turn approximately .010" off the diameter.

If the stock is thinner at the tailstock end, the

tailstock needs to be moved away from the

operator by at least the amount of the

taper. See Figure 31.

NOTICE

Do Not forget to lock down the tailstock after

each adjustment.

SECTION 7: MAINTENANCE

ALWAYS disconnect the electric power to

the machine before servicing. NEVER lubri-

cate your lathe while it is running.

Lubrication

Your Model G4002/3 will function best when it is

clean and well lubricated. Take the time to wipe

down and oil the machine after use. We recom-

mend using ISO 68 or SAE 20W non-detergent

oil unless otherwise specified.

Figure 34. External gears and port.

Apron - Apply lubrication to the apron through

the 2 ball fittings on the top face of the apron and

one near the apron handwheel. See Figure 33.

Figure 33. Viewed from behind for clarity.

Cross-Slide and Compound - These slides are

also supplied with ball fittings in their top surfaces

and should be oiled the same as the apron. See

Figure 33.

Quick Change Gearbox - Lubrication for the

Gearbox is provided through 3 oil points, labeled

oil nipple. Add a squirt or two of oil after every

three-to-four hours of use. See Figure 35.

Motor - The bearings used in the motor are

shielded and lubricated for life.

G4002/3 Gear Head Lathes

Download from Www.Somanuals.com. All Manuals Search And Download.

Tailstock - The tailstock is fitted with one oiling

port. The tailstock barrel may be oiled directly.

Apply oil each week, or after every five uses

(depending on the frequency of operation). Be

sure to clean the slide ways for the tailstock and

lift the tailstock and squirt a few drops of oil on

the ways. It is a good idea to remove the tailstock

once a month and wipe the bottom thoroughly

and replace. See Figure 37.

Slides and Ways - Apply oil to the ways and

slides after each use. Wipe the ways with a clean

rag prior to lubrication to ensure that no grime is

carried along with your lubricant into friction-sen-

sitive areas. Applying oil to the bedways and

other bare metal parts also protect the lathe from

rust and pitting.

Lead Screw and Feed Rod - Be sure to clean

and lubricate the leadscrew, feed rod and switch

control rod. The lead screw and feed rod have a

bearing on the tail stock end support that will

require one to two squirts of oil. See Figure 36.

Headstock Gearbox - The oil in the headstock

should be changed after the first 2 hours of use.

Then, every 6 months, depending on usage. It is

recommended that a light weight, non detergent

oil be used. Viscosity can range from 10W to

30W and may include multi-viscosity oil in this

same range.
