Step 1 of 6
Understand Your Saw
Learn the parts: blade guard, depth adjustment, bevel adjustment, base plate (shoe), trigger, and blade lock. The blade guard automatically covers the blade when not cutting.
Warning
Never disable or remove the blade guard. It's a critical safety feature.
Step 2 of 6
Set Blade Depth
Unplug the saw. Set the blade depth so it extends about ¼" below the material you're cutting. Too deep increases kickback risk and wastes energy.
Step 3 of 6
Support the Material
Place lumber on sawhorses or a work surface. Ensure both sides are supported — the cutoff piece should be free to fall away without binding the blade.
Common Mistake
Unsupported material pinches the blade during cutting, causing kickback.
Step 4 of 6
Mark and Guide Your Cut
Mark your cut line with a pencil. For straight cuts, clamp a straight edge as a guide. The base plate rides along the guide for consistent, accurate cuts.
Step 5 of 6
Make the Cut
Hold the saw firmly with both hands. Start the saw before contacting the wood. Push steadily forward at a moderate pace — don't force it. Let the blade do the work.
Tip
If the saw bogs down, you're pushing too fast. Ease up and let the blade spin freely.

Safety Summary
Always: wear safety glasses and hearing protection, keep both hands on the saw, wait for the blade to stop before setting down, inspect the blade for damage, and keep cords away from the cutting path.
Pro Tip
Score your cut line with a utility knife first to prevent splintering on the show face.
