How do I adjust the speed and mode settings on my DEWALT DWD520 hammer drill?

Adjusting the speed and mode on your DEWALT DWD520 Heavy-Duty Dual Speed Hammer Drill is straightforward. Here's how:

1. Locate the Selector: Find the speed/mode selector collar (often marked as 'D' on the tool). It's positioned near the chuck, where the drill bit is inserted.
2. Changing Speed: To select the speed, rotate the collar. Align it with the drill bit symbol for drilling at speed position 1 (lower speed) or position 2 (higher speed).
3. Switching Modes: To toggle between drilling and hammerdrilling modes, simply turn the collar to the corresponding symbol. The drill bit symbol signifies drilling mode, while the hammer symbol indicates hammerdrilling mode.

Important Note: The gear system is designed to shift only when the drill is turned off. If you encounter any resistance, slightly rotate the chuck by hand to help align the gears while turning the collar.

Always consult the DEWALT DWD520 instruction manual for detailed safety information and optimal operating procedures.
