Be careful not to split the work- piece. See Figure 6B. Wood with splits along the grain may fly off during the operation. With dense wood, drill a hole at the centers and score lines with a saw blade for the spur. -12- G8690 Variable Speed Wood Lathe 1/4" Figure 6B. Spur center set into wood stock. 4. Once the spur center is firmly attached to the workpiece, insert the spur center (with the attached workpiece) into the headstock spindle. Be certain the hex nut is threaded onto the spindle before tapping the spur center in. 5. While supporting the workpiece, slide the tail- stock close to the end of the workpiece and lock it into place. 6. Line up the live center with the workpiece center. Turn the handwheel to press the point of the live center into the workpiece. 7. Lock the tailstock in place. Do not press too firmly or the bearings will bind and overheat. Likewise, do not adjust too loosely or the workpiece will spin off the lathe. Use good judgement. Serious personal injury could result if care is not taken. Speed Selector The variable speed selector allows the adjustment of the spindle R.P.M. Before turning the lathe on, make sure the speed selector knob is set at the lowest R.P.M. (turn counterclockwise). See Figure 7. Once the lathe is turned on, slowly increase the R.P.M. of the lathe by turning the speed selector knob clockwise. Make sure that your finger is poised on the STOP button, just in case there’s a problem. The lathe should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further. If you cannot easily locate the source of an unusual noise or vibration, contact our service department for help. Remember to choose the correct speed for your particular turning project. As a general rule, the larger the workpiece diameter, the slower the speed. Always start at the slowest speed. Speed Selector Knob Figure 7. Operating controls. G8690 Variable Speed Wood Lathe -13 Tool Rest Adjust the tool rest as close to the workpiece as possible without actually coming into contact with the workpiece. Test by hand-turning the work- piece before turning the lathe on. Ensure that the lathe chisel is fully supported by the tool rest. Support the lathe chisel on the tool rest with one hand, while the other hand controls the chisel. See Figure 8. Figure 8. Correct hand placement for operation. Wear a face shield during the test run and operation of this wood working lathe. Failure to do so could result in serious injury. -14-G8690 Variable Speed Wood Lathe SECTION 7: MAINTENANCE General Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Wear safety glasses during the entire maintenance process. Failure to comply may result in serious personal injury. Regular periodic maintenance on your Model G8690 will ensure its optimum performance. Make a habit of inspecting your lathe each time you use it. Check for the following conditions and repair or replace when necessary: 1. Loose mounting bolts. 2. Worn switch. 3. Worn or damaged cords and plugs. 4. Damaged cog tooth belt. The non-painted surfaces on the Model G8690 should be protected against rust and pitting. Wiping the lathe clean after every use ensures that wood dust isn’t allowed to trap moisture against bare metal surfaces. Some woodworkers recommend using automotive paste wax on exposed steel and cast iron surfaces. The wax provides a layer of protection. Avoid waxes that contain silicone or other synthetic ingredients. These materials can find their way into lumber that’s being worked, and can make staining and finishing difficult. If you use paste wax, make sure that it’s 100% Carnauba wax. Lubrication Since all bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them.

If you need parts or help in assembling your machine, or if you need operational information, we encourage you to call our Service Department. Our trained service technicians will be glad to help you. If you have comments dealing specifically with this manual, please write to our Bellingham, Washington location using the address in Section 3 Introduction. We have included some important safety measures that are essential to this machine’s operation. While most safety measures are generally universal, Grizzly reminds you that each workshop is different and safety rules should be considered as they apply to your specific situation. Operating this equipment creates the potential for flying debris to cause eye injury. Always wear safety glasse...
