Setup
Battery Installation and Charging
The DCD796P3 uses DEWALT 18V XR Lithium-Ion battery packs. Ensure the battery is fully charged before first use.
- To install the battery: Align the battery pack with the tool's handle and slide it in until it clicks securely into place.
- To remove the battery: Press the battery release button and pull the battery pack out of the tool.
- To charge the battery: Insert the battery pack into the DEWALT charger (included). Refer to the charger's instruction manual for specific charging procedures and indicators.
Installing and Removing Drill Bits/Accessories
The drill features a keyless chuck for easy accessory changes.
- Rotate the front collar of the chuck counter-clockwise until the chuck jaws are open wide enough to accept the bit.
- Insert the drill bit or accessory fully into the chuck.
- Rotate the front collar clockwise to tighten the chuck jaws securely around the bit. Ensure the bit is centered and firmly gripped.
- To remove the bit, reverse the tightening procedure.
Operating Instructions
Selecting Operating Mode
The mode selector allows you to choose between three operating modes:
- Screwdriving Mode (⚙ icon): For driving screws. Use the torque adjustment collar to set the desired clutch setting. The clutch will disengage once the set torque is reached, preventing overtightening or stripping.
- Drilling Mode (★ icon): For drilling into wood and metal. The clutch is bypassed in this mode, providing maximum torque.
- Hammer Drilling Mode (⚒ icon): For drilling into masonry and concrete. This mode combines rotary action with a hammering action.
Rotate the mode selector collar to align the desired icon with the indicator mark on the drill body.
Setting Torque (Screwdriving Mode Only)
The torque adjustment collar has settings from 1 to 15, plus a drill icon. Select a lower number for smaller screws or softer materials, and a higher number for larger screws or harder materials. Experiment on scrap material to find the appropriate setting.
Selecting Speed
The speed selector switch is located on top of the drill. It has two settings:
- Speed 1 (Low Speed): Provides higher torque for heavy-duty screwdriving and large diameter drilling. (0-550 RPM)
- Speed 2 (High Speed): Provides higher speed for fast drilling with smaller bits. (0-2000 RPM)
Ensure the tool is stopped before changing speed settings.
Operating the Trigger Switch and Forward/Reverse Control
- Trigger Switch: Squeeze the trigger to start the tool. The speed is variable; press further for higher speed.
- Forward/Reverse Button: Push the button from the left side for forward rotation (drilling/driving). Push from the right side for reverse rotation (removing screws/bits). Center position locks the trigger to prevent accidental starting.
