4. Hold the handle firmly and depress the trigger to start the motor. Allow the blade to reach full speed before cutting.
5. Slowly lower the blade through the workpiece, maintaining a steady, controlled motion.
6. Once the cut is complete, release the trigger and allow the blade to stop completely before raising it from the workpiece.

Miter and Bevel Cuts

The DWS771 allows for quick and accurate adjustment of miter and bevel angles. Refer to the markings on the miter table and bevel scale for precise settings. Always ensure locking levers are tightened before making a cut.

Maintenance

Regular maintenance ensures the longevity and safe operation of your DEWALT DWS771 Miter Saw.

• Cleaning: After each use, disconnect the saw and clean off dust and debris from the motor vents, blade guard, and table. Use a soft brush or compressed air.
• Blade Inspection: Regularly inspect the saw blade for sharpness, cracks, or missing teeth. Replace dull or damaged blades immediately.
• Lubrication: Periodically lubricate moving parts as indicated in the detailed service manual (not provided here).
• Carbon Brushes: Check carbon brushes periodically. Replace them when they are worn down to approximately 6mm (1/4 inch) or if the motor sparks excessively.
