How to Use the Dewalt DWS779 Miter Saw
Once you have set up your workspace and are familiar with your tool, you can begin the cutting process. Below is a step-by-step guide to using the DWS779 effectively.
Preparing for a Cut
Before making any cuts, take the following steps:
- Select the Right Blade: For general woodworking, a 10-inch 40-tooth carbide blade is ideal. If you’re working with specialized materials (like composite or aluminum), ensure you have the appropriate blade.
- Adjust the Miter Angle: Depending on your project, use the miter scale to set the desired angle. The DWS779 allows for adjustments from 0 to 60 degrees on the left and 0 to 50 degrees on the right.
- Adjust the Bevel Angle: For bevel cuts, engage the bevel adjustment lever and set the desired angle, typically ranging from 0 to 49 degrees.
Making a Crosscut
Crosscuts are the most common cuts made with a miter saw. Follow these steps:
- Position Your Material: Place your piece of wood flat against the saw’s base, ensuring it’s aligned with the blade.
- Secure Your Material: Ensure your hands are clear of the cutting path and use a clamp if necessary to keep the wood stable.
- Pull the Handle Down: Grasp the saw handle firmly and pull down to lower the blade onto the workpiece, rather than dropping it abruptly.
Making a Bevel Cut
For a bevel cut, ensure that the bevel angle is set correctly:
- Follow the Same Positioning Steps: Make sure the material is positioned securely.
- Execute the Cut: Lower the blade as you would for a regular crosscut. Be cautious with the additional angle the blade will create.
- Complete the Cut: Once the cut is made, raise the handle and retrieve your piece carefully.
Momentary Stop Technique
A valuable technique with the DWS779 is using the momentary stop feature. By releasing the trigger just before the blade exits the material, you can achieve a cleaner finish without tearing out the wood fibers.
Maintaining Your Dewalt DWS779 Miter Saw
Regular maintenance ensures the longevity and efficiency of your miter saw. Here are some key maintenance tips:
Cleaning the Miter Saw
After completing your projects, take the time to clean the weapon:
- Unplug the Saw: Always ensure the tool is disconnected from power before cleaning.
- Dust Extraction: Utilize a vacuum or blower to remove sawdust from the work area and the saw itself.
- Wipe the Surface: Use a damp cloth to clean any residue from the base and table.
Checking the Blade
Regularly inspect the blade for wear:
- Sharpening: If you notice dullness, consider sharpening or replacing the blade.
- Alignment: Ensure the blade remains square to the table, and make adjustments if necessary.
Advanced Tips for Optimal Use
To truly master your Dewalt DWS779 miter saw and achieve professional results, consider these advanced tips:
Use a Stop Block
For repeated cuts of the same length, utilize a stop block. This fixture can help ensure consistency and accuracy across multiple pieces, reducing the likelihood of error.
Practice with Scrap Material
Before starting on your project, practice cutting with scrap wood similar to your project material. This will help you gauge the necessary settings and refine your technique.
Visualize Your Cuts
Before making any cut, visualize the blade’s path to avoid accidental mishaps. Create a clear mental picture of the cuts needed and visualize the final outcome.
