Understanding Technical Definitions
Cross Cut Capacity
Cross cut capacity refers to the maximum width of material that a miter saw can cut at a 90-degree angle.
Bevel Angle Range
The range of angles that the saw blade can tilt to the left or right of a vertical axis. This allows for angled cuts on the workpiece.
Miter Angle Range
The range of angles that the saw blade can rotate to the left or right of a horizontal axis. This allows for angled cuts across the width of the workpiece.
Cutting Capacity (at 90 degrees)
The maximum width and height of the workpiece that the saw can cut when the blade is set at a 90-degree angle.
Cutting Capacity (at 45 degrees)
The maximum width and height of the workpiece that the saw can cut when the blade is set at a 45-degree angle.
XPS Cross-Cut Alignment System
A laser or LED light system that casts a shadow on the workpiece to provide a precise cut line. It helps to increase accuracy and reduce errors.
Blade Diameter
The size of the circular saw blade that is used on the saw. A larger blade diameter allows for larger cuts and higher cutting capacity.
Position Stops
Pre-set stops that allow the user to quickly and easily set the blade to specific angles for common cuts, such as 45 degrees or 90 degrees. They help to save time and improve accuracy.
Safety Tips
- Always wear eye protection, hearing protection, and a dust mask when using the saw. Flying debris and loud noise can be dangerous to your health.
- Keep your work area clean and free from clutter. This reduces the risk of accidents and allows for better visibility when cutting.
- Never touch the blade while it’s still spinning or in motion. Wait for the blade to come to a complete stop before making any adjustments.
- Always use the appropriate blade for the material you’re cutting. Using the wrong blade can be dangerous and cause the saw to malfunction.
- Keep your hands and fingers away from the blade at all times. Use clamps or other tools to hold the workpiece in place while cutting.
- Make sure the blade guard is in place and functioning properly before starting the saw. The guard helps to protect you from the blade while cutting.
- Always use the saw on a stable and level surface. Unstable or uneven surfaces can cause the saw to tip over or shift during use.
- Keep the power cord away from the blade and the workpiece. Accidentally cutting the cord can cause electric shock or damage the saw.
- Always read the owner’s manual and follow all safety guidelines and instructions. Proper use and maintenance of the saw are essential for safety and performance.
