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. To reduce the risk of operator (or bystander) injury or death, anyone operating this machine MUST completely heed the hazards and warnings below.
CHECK WORKPIECE INTEGRITY. Verify each
workpiece is free of knots, splits, nails, or foreign material to ensure it can safely rotate on spindle without breaking apart or causing tool kickback.
PROPERLY PREPARE WORKPIECE. Before mounting, cut off waste portions to balance workpiece for safe rotation and remove large edges that can catch on tooling.
SECURE LOCKS. Verify tool rest, headstock, and tailstock are secure before turning lathe ON.
SECURE WORKPIECE. Use proven setup techniques and always verify workpiece is well-secured before starting lathe. Only use high-quality fasteners with non-tapered heads for faceplate attachment.
ADJUST TOOL SUPPORT. An improperly sup­ported tool may be grabbed or ejected. Adjust tool rest approximately
1
8" above workpiece center line to provide proper support for turning tool. Firmly hold turning tool with both hands against tool rest.
1
4" away from workpiece and
WEAR PROPER PPE. Always wear a face shield and safety glasses when operating lathe. Do not wear gloves, necktie or loose clothing. Keep long hair away from rotating spindle.
USE CORRECT SPEEDS. Select correct spindle speed for workpiece size, type, shape, and condition. Use low speeds when roughing or when turning large, long, or non-concentric workpieces. Allow spindle to reach full speed before turning.
AVOID TOOL KICKBACK. This occurs when turning tool is grabbed or ejected from workpiece with great force. Commonly caused by poor workpiece selection/preparation, improper tool usage, or improper machine setup or tool rest adjustment.
SAFELY PERFORM ROUGHING. Use correct tool. Take light cuts, use low speeds, and firmly support tool with both hands.
USE SHARP TOOLS. Sharp tools cut with less resistance than dull tools. Using dull tools increases the risk of tool kickback or grabbing.
TEST NEW SETUPS. Test each new setup by starting spindle rotation at lowest speed and standing to side of lathe until workpiece reaches full speed and you can verify safe rotation.
REMOVE ADJUSTMENT TOOLS. Remove all chuck keys, wrenches, and adjustment tools before turning lathe ON. These items can become deadly projectiles when spindle is started.
CHECK CLEARANCES. Before starting spindle, verify workpiece has adequate clearance by hand-rotating it through its entire range of motion.
-10 -
SAFELY STOPPING ROTATION. Always allow rotating workpiece to stop on its own. Never put hands or another object on workpiece to stop it.
SAFELY MEASURE WORKPIECE. Only measure workpiece after it has stopped. Trying to measure a spinning workpiece increases entanglement risk.
SANDING/POLISHING. To reduce entanglement risk, remove tool rest before sanding. Never completely wrap sandpaper around workpiece.

SECTION 2: POWER SUPPLY

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.
Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power
The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.
The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.
If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid over­loading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.
For your own safety and protection of
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, con­sult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power sup­ply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)
This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is nec­essary, do not connect the equipment-grounding wire to a live (current carrying) terminal.
Check with a qualified electrician or service per­sonnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, discon­nect it from power, and immediately replace it with a new one.
We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.
Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:
Grounding Requirements
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.
This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug!

Site Considerations

Weight Load
Refer to the 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.
Space Allocation
Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the main­tenance and service described in this manual.
See below for required space allocation.

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a con­crete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Anchoring to Floor

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.
If the machine will be installed in a commercial or workplace setting, or if it is permanently connect­ed (hardwired) to the power supply, local codes may require that it be anchored to the floor.
If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we rec­ommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Workpiece Inspection Adjusting Headstock

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:
Workpiece Type: This machine is intended for turning natural
wood products. Never attempt to turn any composite wood materials, plastics, metal, stone, or rubber workpieces; turning these materials can lead to machine damage or severe injury.
Foreign Objects: Nails, staples, dirt, rocks and other foreign
objects are often embedded in wood. While cutting, these objects can become dislodged and hit the operator, cause tool grab, or break the turning tool, which might then fly apart. Always visually inspect your workpiece for these items. If they can't be removed, DO NOT turn the workpiece.
The Model G0766 headstock 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 secures the tailstock in place. The headstock can be positioned anywhere along the lathe bed.
To position headstock along length of bed:
1. DISCONNECT MACHINE FROM POWER!
2. Loosen headstock lock lever (see Figure 16).
Large/Loose Knots: Loose knots can become dislodged during
the turning operation. Large knots can cause a workpiece to completely break in half during turning and cause machine damage and injury. Choose workpieces that do not have large/loose knots.
Excessive Warping: Workpieces with excessive bowing or twist-
ing are unstable and unbalanced. Never turn these workpieces at high speed, or instability will be magnified and the workpiece can be ejected from the lathe causing injury. Only turn concentric workpieces!
Headstock Lock
Lever
Figure 16. Headstock lock lever location.
3. Slide headstock to desired location on bed,
and use headstock lock lever to secure head­stock in position.
Note: The large clamping hex nut underneath
the headstock will require occasional adjust­ing to ensure proper clamping pressure of the headstock to the bed. Turn this hex nut in small increments to fine tune the clamping pressure as needed.
Always operate lathe with headstock firmly locked to bed. Otherwise, serious personal injury may occur, as workpiece or faceplate could shift during operation or be ejected from lathe.

Tool Rest

Adjusting Tailstock

The tailstock adjusts in the same manner as the headstock.
To position tailstock along length of bed:
1. Loosen tailstock lock lever and move tailstock
to desired position along bed, as shown in Figure 17.
Tailstock Lock
Lever
Figure 17. Tailstock lock lever location.
2. Re-tighten tailstock lock lever to secure
tailstock to bed.
Note: The large clamping hex nut underneath
the tailstock will require occasional adjusting to ensure proper clamping pressure of the tailstock to the bed. Turn this hex nut in small increments to fine tune the clamping pres­sure as needed.
Always operate lathe with tailstock firmly locked to bed. Otherwise, serious personal injury may occur by tailstock moving during operation and workpiece being ejected at high speed.

Adjusting Tool Rest

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 and 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 as needed after making these adjustments.
When adjusting the tool rest, position it as close as possible to the workpiece without actually touching it. This maximizes support where the cutting occurs and minimizes leverage, reducing the risk of injury if a "catch" occurs.
Many woodturners typically set the height of the tool rest workpiece, depending on their height, the type of tool they're using, and the type of operation they're performing. As a rule of thumb: For most (spindle) turning operations, the cutting tool should con­tact the workpiece slightly above centerline. For most inside (bowl) turning operations, the cutting tool should contact the workpiece slightly below centerline.
Keeping all these factors in mind, your main goal when adjusting the tool rest should be providing maximum support for the type of tool being used, in a position that is safe and comfortable for you.
Improperly supported or positioned cutting tools can "catch" on workpiece, ejecting tool from your hands with great force. To reduce this risk, always ensure tool rest is properly positioned for each type of opera­tion, cutting tool is firmly supported against tool rest BEFORE cutting, and cutting tool is properly positioned to cut at the correct angle for tool and operation type.

To position tool rest forward/backward and along the length of the bed:
2. Re-tighten tool rest base lock lever to secure
tool rest assembly in position.
1. Loosen tool rest base lock lever and move tool rest assembly to desired position on lathe bed, as shown in Figure 18.
Note: To maximize support, the tool rest
base should always be locked on both sides of the bed. Never pull the tool rest so far back that it is only secured on one side.

Note: The large clamping hex nut under-
neath the tool rest base will require occa­sional adjusting to ensure proper clamping pressure of the tool rest assembly to the bed. Turn this hex nut in small increments to fine tune the clamping pressure as needed.
Always operate lathe with tool rest assem­bly firmly locked in position. Otherwise, serious personal injury may occur by tool being pulled from operator's hands.
To adjust angle or height of tool rest:
1. Loosen tool rest lock handle (see Figure 18).
2. Position tool rest in desired location.
3. Re-tighten tool rest lock handle to secure tool
rest in position.

Page 32
Spindle Turning Tips:
When turning the lathe ON, stand away from the path of the spinning workpiece until the spindle 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 for the size of workpiece that you are turning (refer to Figure 25 on Page 26).
Keep the turning tool on the tool rest the ENTIRE time that it is in contact with the workpiece.
Learn the correct techniques for each tool you will use. If you are unsure about how to use the lathe tools, read books or magazines about lathe techniques, and seek training from experienced and knowledgeable lathe users.

Faceplate Turning

Faceplate Turning
Faceplate turning is when a workpiece is mounted to the faceplate, which is then mounted to the headstock spindle, as shown in Figure 36. This type of turning is usually done with open-faced workpieces like bowls or plates.
Figure 36. Typical faceplate turning operation.
Eye injuries or respiratory problems can occur while operating this tool. Wear per­sonal protective equipment to reduce your risk from these hazards.
Mounting Workpiece on Faceplate
1. Mark workpiece center in same manner as
described in Spindle Turning (see Page 28).
Note: Cut off corners of workpiece to make it
as close to "round" as possible, as described in Spindle Turning, Step 5 (see Page 29).
2. Center faceplate on workpiece and attach it (see Figure 37) with wood screws.

NOTICE
Only use screws with non-tapered heads (see Figure 38) to attach faceplate to the workpiece. Screws with tapered heads can split faceplate or snap off during operation.
Correct Incorrect
Mounting Workpiece to Backing Block
1. Make backing block from a suitable size
piece of scrap wood.
Note: Faces of backing block must be flat
and parallel to each other, or uneven surfac­es will cause workpiece to spin eccentrically, causing unnecessary vibration and runout. It is best to mount backing block to faceplate and turn other surface flat prior to mounting.
2. Locate and mark center of workpiece and backing block.

3. Drill a
4" hole through center of backing block.
Figure 38. Correct and incorrect screw types.
3. Thread and secure faceplate onto headstock spindle (refer to Installing Faceplate on Page 26).
— If wood screws cannot be placed in
workpiece, faceplate can be mounted to a backing block attached to workpiece (see
Mounting the Workpiece to a Backing Block).
4. Look through hole in backing block to line up
center with workpiece and glue and clamp backing block to workpiece.
Note: Allow glue to cure according to manu-
facturer's instructions.
5. Follow Steps 1–3 under Mounting Workpiece on Faceplate (see Page 30) to
attach backing block to faceplate.

Outboard Turning

Outboard turning is a variation of faceplate turning and is accomplished with the headstock positioned so the faceplate is not directly over the bed, allowing a larger turning capacity than the swing specification of the lathe.
The only way to rotate the headstock on this machine is to remove it from the bed first, which can be a heavy and cumbersome task. A much simpler alternative to removing the headstock is to remove the tailstock and slide the headstock to the other end of the bed. This will position the spindle so it is not directly over the bed whereby outboard turning can safely be accomplished.

To outboard turn:
1. DISCONNECT MACHINE FROM POWER!

Sanding/Finishing

2. Remove tailstock and tool base from machine
by removing hex nuts and clamp washers located underneath assemblies, then lifting them from lathe bed.
3. Loosen headstock, then move it all the way to tail end of lathe bed, as shown in Figure 39.
Figure 39. Example of lathe prepared for
outboard turning.
After the turning operations are complete, the workpiece can be sanded and finished before removing it from the lathe, as shown in Figure 40.
Figure 40. Typical sanding operation.
Note: Whenever sanding or finishing, move tool
rest holder out of the way to increase personal safety and gain adequate working room.
4. Re-tighten headstock to bed.
When outboard turning, ALWAYS use a floor-mounted tool rest and keep tool in contact with rest during all turning opera­tions. Failure to do so could cause tool to be pulled out of operator's control and ejected at high speed.
Sandpaper
Workpiece
Wrapping sandpa­per completely around workpiece could pull your hands into mov­ing workpiece and may cause serious injury. Never wrap sandpa­per or finishing materi­als completely around workpiece.

Selecting Turning
Tools
Lathe tools come in a variety of shapes and sizes, and usually fall into five major categories.
Gouges—Mainly used for rough cutting, detail cutting, and cove profiles. The rough gouge is a hollow, double-ground tool with a round nose, and the detail gouge is a hol­low, double-ground tool with either a round or pointed nose.
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.
Figure 43. Example of a round nose scraper.
Parting Tools—Used for sizing and cut­ting off work. This is a flat tool with a sharp pointed nose that may be single- or double­ground.
Figure 41. Example of a gouge.
Skew Chisel—A very versatile tool that can be used for planing, squaring, V-cutting, beading, and parting off. The skew chisel is flat, double-ground with one side higher than the other (usually at an angle of 20°–40°).
Figure 42. Example of a skew chisel.
Figure 44. Example of a parting tool.
Specialty Tools—These are the unique, special function tools to aid in hollowing, bowl making, cutting profiles, etc. The Swan Neck Hollowing Tool shown on Page 34 is a good example of a speciality tool.

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical com­ponents!
MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpre­dictable results, including serious injury or fire. This includes the installation of unapproved after­market parts.
WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires dis­connected or connected during any wiring task to ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious per­sonal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.
MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.
CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.
EXPERIENCING DIFFICULTIES. If you are expe­riencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.
