2. Safety Information
Always prioritize safety when operating power tools. This miter gauge system is an accessory for a table saw. Adhere to all safety guidelines provided in your table saw's instruction manual in addition to the following:
- Wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and dust mask.
- Ensure your table saw is unplugged before making any adjustments or installing accessories.
- Keep hands clear of the saw blade at all times. Use push sticks or push blocks when necessary.
- Verify that all components of the miter gauge system are securely fastened before operation.
- Do not force the workpiece through the saw. Allow the blade to cut at its own pace.
- Maintain a clean and well-lit work area.
3. Package Contents

4. Setup and Installation
Follow these steps to properly set up your miter gauge system:
4.1. Miter Gauge Compatibility
The miter gauge is designed to work with standard 3/4" x 3/8" miter slots, with or without T-slots. It will not work with smaller saws or tools featuring 5/8" miter slots. Ensure your table saw's miter slots match these dimensions.

4.2. Attaching the Multi-Track Fence
- Align the Multi-Track Fence with the miter gauge.
- Secure the fence to the miter gauge using the provided hardware. Ensure it is firmly attached and square to the miter gauge body.

4.3. Installing the T-Track Flip Stop
- Slide the T-Track Flip Stop into the T-slot of the Multi-Track Fence.
- Position the flip stop as needed for your cut length. The flip stop can be adjusted to work on either the left or right side of the blade.
- Tighten the locking mechanism to secure the flip stop in place.

4.4. Inserting into Table Saw Miter Slot
Carefully slide the assembled miter gauge system into your table saw's miter slot. Ensure it slides smoothly without excessive play or binding. The miter gauge features 4 expansion discs that can be adjusted to remove side play within the miter slot.

5. Operating Instructions
5.1. Setting Angles
The miter gauge features 27 angle indexing stops, with 1-degree step spacing and positive stops at common angles (0°, 10°, 22.5°, 30°, and 45°), both left and right. To set an angle:
- Loosen the locking knob on the miter gauge.
- Rotate the miter gauge head to the desired angle, aligning the indicator with the scale.
- For positive stops, the mechanism will click into place. For intermediate angles, carefully align and then tighten the locking knob securely.

5.2. Using the Flip Stop for Repeat Cuts
The T-Track Flip Stop allows for precise, repeatable cut lengths:
- Measure and position the flip stop on the Multi-Track Fence to the desired cut length. The laser-engraved scale on the fence assists with accurate measurement.
- Tighten the flip stop's locking mechanism.
- Place your workpiece against the fence and the flip stop.
- Make your cut. For subsequent pieces, simply place them against the flip stop for consistent length.
5.3. Making Cross-Cuts and Miter Cuts
- Ensure the miter gauge is securely set to the desired angle.
- Place the workpiece firmly against the fence.
- Hold the workpiece and the miter gauge firmly.
- Turn on the table saw and slowly push the miter gauge and workpiece through the blade. Maintain consistent pressure.
- Once the cut is complete, turn off the saw and wait for the blade to stop before removing the workpiece and offcut.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your miter gauge system:
- Cleaning: After each use, wipe down all components to remove sawdust and debris. A dry cloth is usually sufficient. For stubborn residue, a mild cleaner can be used, ensuring all parts are thoroughly dried afterward.
- Lubrication: Periodically apply a dry lubricant (e.g., silicone spray) to the miter bar to ensure smooth sliding in the table saw slot. Avoid oil-based lubricants that can attract sawdust.
- Inspection: Regularly inspect all fasteners and components for wear or damage. Tighten any loose screws. Replace damaged parts immediately.
- Storage: Store the miter gauge system in a clean, dry place to prevent corrosion and damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Miter gauge binds or sticks in the slot. | Expansion discs are too tight; sawdust buildup in the slot. | Loosen the expansion discs slightly. Clean the miter slot and miter bar. Apply dry lubricant. |
| Excessive play in the miter slot. | Expansion discs are too loose or not properly adjusted. | Adjust the expansion discs to remove side play. |
| Inaccurate angle cuts. | Miter gauge not locked securely; fence not square to the miter gauge. | Ensure the locking knob is tightened. Check and adjust the fence for squareness. |
| Flip stop does not hold position. | Locking mechanism is loose or damaged. | Tighten the flip stop's locking mechanism. Inspect for damage and replace if necessary. |
