Additional Safety Instructions For The Lathe

1.MAKE SURE ALL GUARDS are in place and that the lathe sits on a flat, stable surface.

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.

3.ADJUST TOOL HOLDER to provide proper support for the turning tool you will be using. Test tool holder clearance by rotating workpiece by hand before turning lathe on.

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.

5.NEVER CHANGE FEED RATE or spindle speeds while the lathe is turning.

6.NEVER REVERSE MOTOR DIRECTION while the lathe is running.

7.DO NOT STOP LATHE USING YOUR HAND against the workpiece.

8.DO NOT LEAVE LATHE RUNNING UNATTENDED for any reason.

9.NEVER OPERATE THE LATHE WITH DAMAGED OR WORN PARTS. Maintain your lathe in proper working condition. Perform routine inspections and maintenance promptly when called for. Put away adjustment tools after use.

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 maintenance procedure.

11.KEEP LOOSE CLOTHING ARTICLES such as sleeves, belts or jewelry items away from the lathe spindle.

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.

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.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment or poor work results.

Like all power tools, there is danger associated with the Model G4000 Metal Lathe. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this tool with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored serious personal injury may occur.

SECTION 2: CIRCUIT REQUIREMENTS

110V Operation

Grounding

The Model G4000 is wired for 110 volt, single phase operation only. The 3⁄4 HP motor will safely draw 12 amps at 110V. A 15-amp fuse or circuit breaker should be used when connecting this metal lathe. Circuits rated any higher are not adequate to protect the motor.

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 service department.

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 G4000, 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.

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This tool is equipped with a power cord having an equipment-grounding conductor. See Figure 1. The outlet must be properly installed and grounded in accordance with all local codes and ordinances.

This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. 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.

Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser. Avoid chlorine-based solvents as they may damage painted surfaces should they come in contact. Always follow the usage instructions on the product 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.

Do not use gasoline or other petroleumbased 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.

1.Floor Load: The Model G4000 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 bolting the G4000 to the stand are already in place. If you are using your own bench, ensure that it is strong enough to handle the G4000 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.

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 location for your lathe.

3.Lighting and Outlets: Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle amperage 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.

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 youngsters 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

Mounting

Chucks

This lathe model should be securely mounted to a stand or benchtop. An accessory stand is available from Grizzly, please see our current catalog for pricing. There are two holes at each end of the lathe base which can be used to secure machine to the base.

The lathe does not require a great deal of assembly. This section details the installation of the various 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.

DO NOT attempt to start this machine until you have completed all of the assembly and control familiarization steps. When performing the assembly steps, ensure that the switch is off and the power is disconnected. Failure to comply with this could cause inadvertent starting of the machine which can result in serious operator injury.

Lubrication

The G4000 is shipped from the factory pre-lubri- cated. 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.

The Model G4000 Metal Lathe comes equipped with a 4'' 3-jaw chuck (already installed), a 7'' 4- jaw chuck and a face plate.

The 3-jaw chuck is a scroll-type chuck, meaning that all three jaws move in unison when adjustments 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 3 and 4-jaw chucks have a setscrew in the hub of the back plate. Figure 2. This setscrew prevents the chucks from unscrewing when rotating the lathe in the reverse direction. Prior to removing the chuck, loosen the setscrew in the hub of the back plate.

Setscrew

Figure 2. Typical chuck mounting.

ALWAYS place a piece of plywood over the ways of the lathe before removing or installing a chuck. This helps in providing a flat surface for the chuck to land on, thereby avoiding a potential finger pinch situation.

Use the chuck removal bars supplied to remove the 3 or 4-jaw chucks. Figure 3. Use one bar to hold the spindle stationary, the other to unscrew the chuck. Turn the chuck counter-clockwise to remove.

Figure 3. Chuck removal bars in place.

To mount one of the standard chucks, line up the desired chuck (or face plate) with the threaded spindle. Thread the chuck in place. Take care to ensure that the threads on both the headstock and the chuck are clean and free of obstructions before mounting.

Never leave a chuck key or chuck removal bar in the chuck or spindle when they are not in use. If the machine is accidentally started with these in place, they can become projectiles and cause serious injury.

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 diameter should be supported by the live center.

The tailstock barrel and live center have a Morse taper #2. Before assembling these, insure that the mating surfaces are “white glove” clean. These parts will last longer and remain accurate when properly maintained. Insert the end of the live center into the tailstock 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 1⁄2'' and not more than 3''.

See Figure 4.

To remove the live center, back the tailstock barrel 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.

Figure 4. Live center installed in tailstock.

Steady Rest

Follow Rest

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 locking plate.

2.A single M8-1.25 x 55mm cap screw, along with a nut and washer, holds the steady rest in place. See Figure 5.

3.The sliding fingers on the center steady rest should receive periodic lubrication while in use to prevent premature wear.

Sliding Fingers

Cap Screw

Figure 5. Steady rest in place.

The follow rest is normally used with small diameter stock to prevent the workpiece from ''springing'' under pressure from the turning tool. To install the follow rest:

1.The follow rest is secured to the saddle with two cap screws. See Figure 6.

2.The sliding fingers on the follow rest are similar to those on the steady rest, and should be lubricated to prevent premature wear.

SECTION 5: CONTROLS

Spindle Speeds

The rotating speed of the headstock is controlled by the positioning of the belts on the pulleys. See Figure 7. These are accessed by removing the cover on the end of the headstock. Refer to the chart at the end of this manual or the plate on the headstock (Figure 8) to determine which belt combinations produce what speeds. The speed settings available on this machine are 130, 300, 400, 600, 1000 and 2000 RPM.

Figure 8. Spindle speed portion of machine plate.

This belt tensioning lever on the top of the headstock loosens the drive belt to enable the operator to change speeds. See Figure 9. The tension release lever can also be used as a clutch while the machine is in operation.

NEVER reach across a rotating chuck or plate. The use of the Belt Tension Release Lever as a clutch should be restricted to those times when starting a heavier part turning and then at very low speed.

Figure 9. Belt tensioning lever.

-12-	G4000 9'' x 19'' Lathe

Feed Rate

The lever at the bottom of the headstock changes the feed rate, or the number of threads- per-inch. See Figure 9. The lever can be engaged in any of nine different positions. When used in conjunction with the interchangeable gears supplied it is possible to achieve a wide variety of feed or threading rates.

Figure 10. Feed rate selector lever.

The machine plate describes some of the more typical settings which might be used. Figure 11 shows the feed rate portion of the machine plate. Looking at the first column, this means that a feed rate of .0023'' can be achieved by putting the feed lever in position 9 with a 28 tooth gear installed at A, and 80 tooth gears at B and C.

Threading feed rates are described in Figures 12 and 13. An 8 thread per inch feed is the result of having a 60 tooth gear at A, a 30 tooth gear at B, and the lever in position 1.

A metric 2mm pitch requires the lever to be in position 7 and would use the same A and B gears installed above. However the gear between them changes from a 120 tooth to a 127 tooth. Also note that the alignment of gears A and B are offset so that A now engages the 127 tooth gear and B engages the 120 tooth gear. The shaft for position B is provided with a spacer which can be installed behind the gear to change its position.
