5. Turn the speed dial counterclockwise to set the spindle speed at zero. 6. Connect the lathe to power. 7. 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 Basic Controls To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes and lungs could result from using this machine without proper protective gear. Always wear a face shield and respirator when operating this machine. See Figure 11 and refer to the list of controls below to familiarize yourself with the lathe controls.
Operation Overview This overview gives you the basic process that happens during an operation with this machine. Familiarize yourself with this process to better understand the remaining parts of the Operation section. To complete a typical operation, the operator does the following: 1. Examines the workpiece to make sure it is suitable for turning. No extreme bows, knots, or cracks should exist. 2. Prepares and trims up the workpiece in a jointer or table saw to make it roughly concentric.
Tailstock Inboard Tool Rest 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. The tool rest holder is equipped with a camaction clamping system to secure it to the lathe bed. When the tool rest holder lock lever is tightened, a locking plate lifts up and secures the tool rest assembly to the bed.
Outboard Tool Rest Adjusting Tool Rest Height 1. Loosen the tool rest lock handle and adjust the angle or height of the tool rest. 2. Position the tool rest approximately 1⁄4" away from the workpiece and approximately 1⁄8" above the workpiece center line (Figure 14). 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. To use the outboard tool rest: 1.
Installing/Removing Headstock Center Removing Headstock Center Tools Needed Qty Knockout Rod..................................................... 1 To remove the headstock center: The included spur center installs into the headstock spindle with an MT#2 tapered fit. 1. DISCONNECT LATHE FROM POWER! 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. 2.
Installing/Removing Tailstock Center The included live center installs into the tailstock quill with an MT#2 tapered fit. To install the center into the tailstock quill: 1. Loosen the quill lock handle and rotate the tailstock handwheel until the quill extends about 1" (see Figure 18). To remove the center from the tailstock quill: 1. Loosen the quill lock handle. 2. Hold the center with a rag or a glove so the center does not fall to the floor when it is pushed free of the tailstock. 3.
Installing Faceplate/ Handwheel Always disconnect the lathe from power before using the spindle lock feature. Never resume turning operations without making sure that the spindle lock is disengaged and the spindle turns freely by hand. Otherwise personal injury or property damage could result. 3. Rotate the spindle by hand until the lock pin engages and keeps the spindle from rotating. 4.
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 (Figure 21). Spindle A = Low Range 100-1000 RPM B = Mid Range 1000-2000 RPM A B C = High Range 2000-3000 RPM C Motor Figure 21. Speed ranges for each belt position. When turning a workpiece where a lot of material must be removed and a rough finish does not matter, low range, which has more torque, is best.
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 24). 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 30 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 (Figure 31). Workpiece Pencil Lines Marked Diagonally Across Corners Workpiece Center Figure 30. Typical spindle turning operation. Figure 31.
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 (Figure 32). 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. 1/4" 10.
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.
ACCESSORIES SECTION 5: ACCESSORIES G1194—3-Jaw Chuck A "must have" for the serious wood turner. This 3-jaw chuck is a self-centering style chuck used mostly for round work. All three jaws tighten together at the same time. Jaws are reversible for expanded work holding capacity. Threaded insert required for mounting! G3167—1 1⁄4" x 8 TPI RH Threaded Insert This threaded insert is required to mount a 3- or 4-jaw chuck to your wood lathe.

SECTION 6: MAINTENANCE Cleaning Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily Check: • Loose mounting bolts. • Worn or damaged wires. • Worn control panel buttons or dials. • Any other unsafe condition.
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 47, 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 51. 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. Lubrication Locations Figure 54. Locations to lubricate bottom of tool rest holder. 4.

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. Checking Belt Loosen the motor lock lever shown in Figure 56, raise the motor up using the height lever, then let the motor hang down on its own weight to tension the belt.
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 60). 8. End Plate Spindle Lock Loosen the motor tension lock (see Figure 62), 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 60. Removing spindle lock mechanism. 6. Remove the end plate, then open the belt cover. 7.
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 64–65. 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 67. 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 69). 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 70), making sure the shoulder of the hub faces the headstock, then tighten the inner set screws on the hub. 30. Reinstall the belt on the appropriate motor pulley groove. 31. Properly re-tension the belt (refer to Tensioning Belt on Page 41 for detailed instructions). Shoulder Hub Adapter Figure 70. Threading on mounting hub. 29. Thread the handwheel onto the mounting hub, then tighten the outer set screws on the mounting hub (see Figure 71).
