3. Setup and Assembly
Unpacking and Inspection
Carefully remove the miter saw and all accessories from the packaging. Inspect for any damage that may have occurred during shipping. Ensure all components listed below are present.
Figure 2: Miter Saw and Included Components
Included Components
Your Makita LS1019L miter saw typically includes the following items:
- 10" x 5/8" 60T Micro-Polished Miter Saw Blade
- Dust Bag
- Hex Wrench 6 (Part No. 781044-6)
- Triangular Rule (Part No. 762001-3)
- Vertical Vise (Part No. 122854-6)
Blade Installation
- Ensure the saw is unplugged from the power source.
- Refer to the saw's specific instructions for removing the blade cover and arbor nut.
- Place the 10-inch blade onto the arbor, ensuring the teeth are oriented correctly for cutting.
- Reinstall the arbor nut and blade cover securely.
Dust Bag Attachment
Attach the included dust bag to the dust port on the saw. Ensure it is securely fastened to optimize dust collection during operation.
Adjusting Fences and Angles
Before operation, verify that the fences are properly aligned and secured. Adjust miter and bevel angles as needed for your specific cuts. The saw features a dual-bevel system for flexibility.
Laser Calibration
The integrated laser assists in precise cutting. Consult the detailed instructions in the full manual for calibrating the laser to ensure it accurately indicates the cut line.
4. Operating Instructions
Powering On/Off
Connect the saw to a 120V power outlet. The 15 amp direct drive motor features a soft start for smooth power-ups. To start, depress the trigger switch. Release the switch to engage the electric brake and stop the blade quickly.
Making Miter Cuts
Adjust the miter table to the desired angle (up to 60 degrees right and 47 degrees left). Secure the workpiece against the fence and table using the vertical vise. Lower the blade slowly through the material.
Making Bevel Cuts
Unlock the bevel adjustment and tilt the saw head to the required angle (up to 45 degrees left or right). Lock the bevel angle securely before making the cut.
Making Compound Cuts
For compound cuts, set both the miter and bevel angles simultaneously. Ensure the workpiece is stable and properly supported.
Using the Sliding Function
The unique 2-steel rail sliding system allows for increased cutting capacity. For wider materials, pull the saw head forward, start the cut, and push the saw head back through the workpiece. This enables cutting of materials like 4x4 dimensional lumber in one pass and crown molding up to 6-5/8 inches (nested).

Using the Laser Guide
Activate the laser guide to project a line onto your workpiece, indicating the precise path of the blade. This aids in accurate alignment before cutting.

5. Maintenance
Cleaning and Dust Collection
- Regularly empty the dust bag to maintain effective dust collection.
- Use a brush or compressed air to clean sawdust and debris from the motor vents, blade guard, and sliding rails.
- Ensure all moving parts are free from obstruction.
Blade Inspection and Replacement
- Inspect the blade regularly for sharpness, cracks, or missing teeth. A dull or damaged blade can cause kickback and inaccurate cuts.
- Replace worn blades with a new 10-inch blade suitable for your application.
General Inspection
- Check all screws and fasteners for tightness.
- Inspect the power cord for damage.
- Ensure the blade guard operates smoothly and returns to its closed position.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate or rough cuts | Dull or damaged blade; improper blade/rail alignment; loose fence; workpiece not secured. | Replace blade; check and adjust fence alignment; ensure workpiece is clamped; if blade/rail alignment is suspected, contact service. |
