How to replace power cord and switch on Shop Smith 10 ER?

Replacing the power cord and switch on a Shop Smith 10 ER, a versatile combination woodworking tool, is a task that can be done with some basic electrical skills and tools. Here's a step-by-step guide on how to replace the power cord and switch on your Shop Smith 10 ER:

1. Safety Precautions:
Safety is paramount when working with power tools and electrical components. Before starting any work, ensure the Shop Smith 10 ER is unplugged and disconnected from the power source. Also, wear appropriate safety gear, including safety glasses and gloves.
2. Gather the Necessary Tools and Materials:
You'll need several tools and materials for this task, including a screwdriver set, wire strippers, wire connectors (wire nuts), electrical tape, a replacement power cord with a plug, a replacement switch (if necessary), and a continuity tester or multimeter.
3. Identify the Problem:
Before proceeding, diagnose the issue with your Shop Smith 10 ER. Determine if the power cord, switch, or both need replacement. If the power cord is frayed, damaged, or has exposed wires, it likely needs replacement. If the switch is malfunctioning or damaged, it may also require replacement.
4. Disconnect the Old Power Cord:
Locate the old power cord, which is typically connected to the rear of the Shop Smith 10 ER near the motor. Carefully disconnect the old cord from the motor terminals. Take note of the wire connections to ensure proper reconnection later.
5. Remove the Old Switch (if necessary):
If you're replacing the switch, disconnect the old switch from the power cord and motor wires. Label the wires or take a photo to remember the correct connections.
6. Prepare the New Power Cord:
If you are replacing the power cord only, cut the damaged cord near the point of damage and strip the insulation from the wire ends to expose about 1/2 inch of bare wire.
7. Prepare the New Switch (if necessary):
If you're replacing the switch, prepare the new switch by connecting the wires to the appropriate terminals as per the manufacturer's instructions. Typically, there will be terminals labeled "Line" or "Power In" and "Motor" or "Power Out." Connect the wires accordingly, ensuring they are securely tightened.
8. Connect the New Power Cord:
If you are replacing the power cord, connect the stripped wire ends to the motor terminals following the same configuration as the old cord. Typically, one wire is connected to the "Line" or "Power In" terminal, and the other goes to the "Motor" or "Power Out" terminal. Use wire connectors (wire nuts) to secure the connections and wrap them with electrical tape for added protection.
9. Connect the New Switch (if necessary):
If you replaced the switch, connect the wires from the new switch to the corresponding wires on the power cord and motor. Secure the connections with wire connectors (wire nuts) and electrical tape.
10. Test the Connections:
Before reassembling the Shop Smith 10 ER, use a continuity tester or multimeter to ensure that the electrical connections are secure and there are no short circuits. Check for continuity between the plug and the motor to confirm proper wiring.
11. Secure the New Power Cord:
Route the new power cord through the appropriate channels or clamps to secure it in place and prevent it from getting tangled or damaged during operation.
12. Reassemble the Shop Smith 10 ER:
Reattach any covers or panels that were removed during the process. Ensure that all components are properly secured.
13. Plug In and Test:
Plug the Shop Smith 10 ER into a properly grounded electrical outlet, and turn on the switch to test its operation. Verify that the motor runs smoothly, and the tool functions as expected.
14. Final Checks:
After testing, inspect the entire assembly to ensure there are no loose connections, exposed wires, or safety hazards. Make any necessary adjustments to secure components or wires.

By following these steps, you can replace the power cord and switch on your Shop Smith 10 ER safely and effectively. If you are not confident in your electrical skills or encounter any difficulties during the process, it's advisable to seek the assistance of a qualified electrician or technician to ensure the job is done correctly and in compliance with safety standards. Proper maintenance and repair of your Shop Smith 10 ER can help prolong its lifespan and ensure safe operation for your woodworking projects.
