SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts. HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material.
Additional Safety for Wood Lathes Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Rotating workpieces can come loose and strike operator or bystanders with deadly force if they are improperly secured, rotated too fast, or are not strong enough for the rotational forces required for turning. Improper tool setup or usage can cause tool kickback or grabbing, resulting in impact injury or entanglement.
SECTION 2: POWER SUPPLY Availability Circuit Requirements for 220V Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.
Grounding Instructions This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current. The power cord and plug specified under “Circuit Requirements for 220V” on the previous page has an equipment-grounding wire and a grounding prong.
SECTION 3: SETUP Needed for Setup Inventory The following are needed to complete the setup process, but are not included with your machine. The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them. Description Qty • Additional People.......................... At Least 1 • Safety Glasses................ 1 For Each Person • Cleaner/Degreaser...................... As Needed • Disposable Shop Rags................
Cleanup The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.
Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Moving & Placing Lathe The Model G0694 is a heavy machine (approx. 580 lbs.) Serious personal injury may occur if safe moving methods are not used. To be safe, get assistance and use power lifting equipment rated for at least 750 lbs. to move the shipping crate and remove the machine from the crate. 4. Figure 9. Lifting straps positioned to lift the lathe. 5. To move and place your lathe: 1. Remove the top crate from the shipping pallet. 2.
Anchoring to Floor Number of Mounting Holes............................. 8 Diameter of Mounting Hardware.................. 3 ⁄ 8" Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.
Test Run 4. Twist EMERGENCY STOP button clockwise until it springs out (see Figure 11). This resets the switch so the machine can start. Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly. If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again.
6. Turn the speed dial counterclockwise to set the spindle speed at zero. 7. Connect the lathe to power. 8. Verify that the machine is operating correctly by pushing the ON button, then use the speed dial to increase the spindle speed. —When operating correctly, the machine runs smoothly with little or no vibration or rubbing noises. —Investigate and correct strange or unusual noises or vibrations before operating the machine further.
SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide.
Workpiece Inspection Adjusting Tailstock Some workpieces are not safe to turn or may require modification before they are safe to turn. Before turning, inspect all workpieces for the following: The tailstock is equipped with a cam-action clamping system to secure it to the lathe bed. When the lever is tightened, a locking plate lifts up underneath the bed and clamps the tailstock in place. • • • • Workpiece Type: This machine is intended for turning natural wood products.
Adjusting Tool Rest Positioning Inboard Tool Rest on Bedway 1. The tool rest assembly consists of two components: the tool rest base (or banjo) and the tool rest. The tool rest base moves forward/backward along the length of the lathe bed. The tool rest rotates and moves up and down in the tool rest base. Locks for both components allow you to secure the tool rest in position after making these adjustments.
Outboard Tool Rest When the workpiece is larger than 20" in diameter, mount the workpiece on the outboard side of the lathe and use the outboard tool rest. Installing/Removing Headstock Center The included spur center installs into the headstock spindle with an MT#2 tapered fit. To use the outboard tool rest: 1. While firmly holding the tool rest support rod, loosen the lock levers shown in Figure 16. Installing Headstock Center 1. DISCONNECT MACHINE FROM POWER! 2.
Removing Headstock Center Tools Needed Qty Knockout Rod..................................................... 1 Installing/Removing Tailstock Center To remove the headstock center: 1. DISCONNECT LATHE FROM POWER! 2. Hold the center with a rag or a glove so the center does not fall to the floor when it pops free of the spindle. 3. Insert the knockout rod through the outbound end of the spindle and firmly tap the center to remove it, as shown in Figure 18.
Installing Faceplate/ Handwheel 3. Rotate the spindle by hand until the lock pin engages and keeps the spindle from rotating. 4. Apply a thin coat of light machine oil on the spindle threads, then thread the faceplate or handwheel onto the spindle until it is snug. 5. Tighten the four faceplate or handwheel set screws just behind the faceplate to secure it to the spindle (see Figure 21). Always disconnect the lathe from power before using the spindle lock feature.
Adjusting Spindle Speeds The Model G0694 has three speed ranges for maximum turning options. These ranges are selected by changing belt positions on the motor and spindle pulleys (see Figure 22). Refer to the chart in Figure 23 for help choosing the correct spindle speed. Note that both the diameter of the workpiece and the type of cutting determines the spindle speed.
3. Open the cabinet door, loosen the lock lever, pull up on the height lever to raise the motor to the highest position, then re-tighten the lock lever to secure the motor in place (Figure 25). Lock Lever Indexing Indexing on a lathe is typically used for workpiece layout and other auxiliary operations that require equal distances around the workpiece circumference, such as clock faces or inlays.
Selecting Turning Tools • Lathe tools come in a variety of shapes and sizes, and usually fall into five major categories. • Scrapers—Typically used where access for other tools is limited, such as hollowing operations. This is a flat, double-ground tool that comes in a variety of profiles (round nose, spear point, square nose, etc.) to match many different contours. Gouges—Mainly used for rough cutting, detail cutting, and cove profiles.
Spindle Turning Setting Up for Spindle Turning 1. Spindle turning is the operation performed when a workpiece is mounted between the headstock and the tailstock (see Figure 31 for an example). Find the center point of both ends of your workpiece by drawing diagonal lines from corner to corner across the end of the workpiece (See Figure 32). Workpiece Pencil Lines Marked Diagonally Across Corners Workpiece Center Figure 31. Typical spindle turning operation. Figure 32.
5. Making sure the spur center is aligned with the workpiece center you marked earlier, drive the spur center least 1⁄4" into the end of the workpiece (see Figure 33). ¼" Do not press the workpiece too firmly with the tailstock or the bearings will bind and overheat. Likewise, do not adjust too loosely or the workpiece will spin off the lathe. Use good reason and care, otherwise, serious personal injury could result. 10. Properly adjust tool rest to workpiece (see Adjusting Tool Rest on Page 21). 11.
Spindle Turning Safety Tips When turning the lathe ON, stand away from the path of the spinning workpiece until the lathe reaches full speed and you can verify that the workpiece will not come loose. • • Use the slowest speed when starting or stopping the lathe. • Select the right speed range and speed for the size of the workpiece and the type of cut (refer to Adjusting Spindle Speed on Page 25 for detailed instructions and guidelines). • Learn the correct techniques for the tools you use.
Using Backing Block If wood screws cannot be placed in the workpiece, then the faceplate can be mounted on a backing block that is glued to the workpiece (see Figure 36 for an example). Outboard Turning Keep the lathe chisel against the tool rest the ENTIRE time you are cutting or when feeding the chisel into the workpiece. Otherwise, the spinning workpiece could knock the chisel out of your hands or pull your hands into the workpiece, resulting in serious entanglement or impact injuries.
Sanding/Finishing After the turning operations are complete, the workpiece can be sanded and finished before removing it from the lathe (see Figure 38 for an example). Note: Whenever sanding or finishing, move the tool rest holder out of the way to increase personal safety and gain adequate working room. Sandpaper Workpiece Wrapping the sandpaper completely around the workpiece could pull your hands into the moving workpiece and cause serious injury.

SECTION 6: MAINTENANCE To reduce risk of shock or accidental startup, always disconnect machine from power before adjustments, maintenance, or service. Schedule For optimum performance from this machine, this maintenance schedule must be strictly followed. Ongoing To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations: • • • • Loose mounting bolts.
Lubricating Spindle Bearings 1. DISCONNECT LATHE FROM POWER! 2. Loosen the set screws closest to the faceplate on the inboard mounting hub and remove the faceplate. 3. Loosen the set screws on the inner face of the mounting hub, as shown in Figure 46, then remove the mounting hub. Faceplate 8. Wipe the outer and inner race of the spindle bearing to remove extra grease. 9. Reinstall the inboard mounting hub and the faceplate. 10.
12. Loosen the set screws on the spanner nut, and use a spanner wrench or a hammer and a punch to loosen and remove the nut, as shown in Figure 50. General Lubrication An essential part of lubrication maintenance is cleaning the components before lubricating them. This step is critical because dust and chips build up on lubricated components, which makes them hard to move. Simply adding more grease to builtup grime will not result in smooth moving parts.
5. Wipe off any excess oil and re-install the tailstock on the bed. 6. Loosen the quill lock handle and rotate the tailstock handwheel until the quill extends fully (approximately 31⁄2"). 7. Clean the outside and inside of the quill with a rag and mineral spirits. 8. Place a few drops of light machine oil on a rag and wipe down the inside and outside of the quill so only a minimal amount of oil remains. 9. Return the quill to the prior position.

Belt Adjustment For optimal power transmission from the motor to the spindle, the belt must be in good condition and properly tensioned. The belt should be checked for cracks, fraying and wear. Check belt tension every three months; more often if the lathe is used frequently. Tensioning Belt 1. DISCONNECT LATHE FROM POWER! 2. Loosen the motor lock lever shown in Figure 55, raise the motor up using the height lever, then let the motor hang down on its own weight to tension the belt. Checking Belt 1.
Changing Belt/ Bearing Service Removing the belt is a special procedure that should not be rushed. Only replace the belt if it is slipping/damaged or if you need to replace the spindle bearings. For this procedure you will remove the handwheel and mounting hub, hub adapter, spanner nut, outboard spindle bearing, end plate and speed sensor. You will also need to reset the spindle bearing preload and reinstall all of the components. Set aside approximately two hours to perform this procedure.
5. Unthread the lock nut on the spindle lock mechanism, then remove the unit (see Figure 59). 8. End Plate Spindle Lock Loosen the motor tension lock (see Figure 61), raise the motor up as far as possible using the height lever, tighten the tension lock, then remove the belt from the motor pulley. Motor Tension Lock Height Lever Figure 59. Removing spindle lock mechanism. 6. 7. Remove the end plate, then open the belt cover.
NOTICE Do not spin a spindle bearing while blowing it off with compressed air or it could fly apart. 14. Place a thick layer of grease on the bottom of your palm, and in a sweeping motion, use the large side of the bearing cage to scrape the grease off your palm and into the spaces between the rollers. Continue doing this while rotating the bearing 360º until the grease emerges from the other side of the bearing cage, as shown in Figures 63–64. 15. Place the belt around one of the pulley grooves.
19. While an assistant holds the metal rod through the faceplate to prevent the spindle from turning in the headstock, tighten the spanner nut until it is snug and seat the outboard bearing, as shown in Figure 66. 22. Put on a pair of leather gloves and remove the spanner nut. 23. Reinstall the speed sensor with the screws you removed earlier (see Figure 68). Make sure the cord does not touch the pulley sheaves or hang down near them.
28. Slide the mounting hub onto the adapter (see Figure 69), making sure the shoulder of the hub faces the headstock, then tighten the inner set screws on the hub. 29. Thread the handwheel onto the mounting hub, then tighten the outer set screws on the mounting hub (see Figure 70). Shoulder Adapter Figure 69. Threading on mounting hub. Figure 70.
