Adjusting the speed and mode on your DEWALT DWD520 Heavy-Duty Dual Speed Hammer Drill is straightforward. Here's how:
- Locate the Speed/Mode Selector Collar: Find the collar (often labeled 'D') near the chuck of your drill.
- Changing Speed: To select a speed, rotate the collar. Position 1 (indicated by a drill bit symbol) provides lower speed, ideal for tasks requiring more torque. Position 2 (also with a drill bit symbol) offers higher speed for faster drilling.
- Switching Modes: To change between drilling and hammer drilling modes, turn the collar to the corresponding symbol. The drill bit symbol represents standard drilling mode. The hammer symbol activates the hammer drilling function for use on masonry or concrete.
Important Note: The gear train is designed to shift when the tool is off. If you encounter any resistance while turning the collar, ensure the drill is switched off, and you may need to rotate the chuck slightly by hand to align the gears. Always consult the DEWALT DWD520's instruction manual for detailed safety information and optimal usage practices.
