4. Setup and Installation
This section outlines the steps for replacing the lower blade guard assembly on your Ryobi miter saw. Refer to your miter saw's original manual for specific disassembly instructions if needed.
- Power Disconnection: Ensure the miter saw is unplugged from the power outlet.
- Access the Guard Area: Depending on your specific miter saw model (TSS102L or TS1345L), you may need to remove the blade or other components to gain access to the existing lower blade guard. Consult your saw's manual for detailed steps.
- Remove Old Guard: Carefully unfasten any screws, pins, or clips securing the old lower blade guard assembly. Note the orientation and attachment points for reassembly.
- Install New Guard: Position the new RYOBI Lower Blade Guard Assembly (080016005704) into place. Ensure all mounting points align correctly.
- Secure New Guard: Fasten the new guard using the original screws, pins, or clips. Ensure all connections are tight and secure. Do not overtighten.
- Test Movement: Manually operate the guard to ensure it moves smoothly and freely without obstruction. It should retract fully when the saw head is lowered and return to cover the blade when the saw head is raised.
- Reassemble Saw: Reinstall any components that were removed to access the guard, such as the saw blade or blade cover.
- Final Check: Before plugging in the saw, perform a final visual inspection to ensure all parts are correctly installed and secured.

5. Operating Instructions
Once the new lower blade guard assembly is correctly installed, the operation of your miter saw remains unchanged. The guard is an integral safety feature that automatically retracts as the blade enters the workpiece and covers the blade when the saw is lifted. Always ensure the guard is functioning correctly before each use.
- Pre-Operation Check: Before each use, verify that the lower blade guard moves freely and fully covers the blade when the saw is in the resting position.
- Maintain Clear Path: Ensure no debris or obstructions hinder the guard's movement during operation.
- Never Bypass: Do not attempt to tie back, remove, or otherwise disable the lower blade guard. It is a critical safety device.
6. Maintenance
Regular maintenance of the lower blade guard ensures its longevity and proper safety function.
- Cleaning: Periodically clean the blade guard to remove sawdust, debris, and resin buildup. Use a soft brush or compressed air. Avoid harsh chemicals that could damage the plastic components.
- Lubrication: The pivot points of the guard should remain free-moving. If movement becomes stiff, apply a small amount of dry lubricant (e.g., silicone spray) to the pivot points, ensuring it does not interfere with the blade or motor.
- Inspection: Regularly inspect the guard for signs of wear, cracks, or damage. Pay close attention to the clear plastic shield for visibility issues. Replace the assembly if any damage is found.
