2. General Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools.

2.1 Work Area Safety

  • Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
  • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2.2 Electrical Safety

  • Power tool plugs must match the outlet. Never modify the plug in any way.
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

2.3 Personal Safety

  • Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
  • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
  • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to battery pack, picking up or carrying the tool.
  • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

4. Setup

The DCD800B is a bare tool, meaning the battery pack and charger are sold separately. Ensure you have a compatible DEWALT 20V MAX battery and charger before proceeding.

4.1 Battery Installation and Removal

  1. To install the battery pack (sold separately), align the battery pack with the rails inside the tool's handle. Slide the battery pack firmly into the handle until it latches into place.
  2. To remove the battery pack, press the release button on the front of the battery pack and pull the battery pack out of the handle.

4.2 Chuck Operation

  1. To open the chuck jaws, rotate the chuck collar counter-clockwise until the jaws are wide enough to accept the bit.
  2. Insert the drill bit or driver accessory into the chuck. Ensure the bit is centered and fully seated.
  3. Rotate the chuck collar clockwise to tighten the jaws firmly around the bit. Hand-tighten securely.

4.3 Belt Hook Attachment

The DCD800B includes a belt hook. To attach it, align the hook with the designated screw hole on either side of the tool's base and secure it with the provided screw.

5. Operating Instructions

5.1 Powering On/Off and Variable Speed Trigger

The tool is activated by pressing the trigger switch. The speed of the tool is controlled by the amount of trigger depression; the further the trigger is pressed, the higher the speed.

5.2 Speed Settings

The DCD800B features a 2-speed transmission. Use the speed selector switch located on top of the tool:

  • Position 1 (Low Speed): For high-torque applications, such as driving large fasteners or drilling large holes. (0-650 RPM)
  • Position 2 (High Speed): For fast drilling or driving smaller fasteners. (0-2,000 RPM)

5.3 Clutch Settings

The adjustable clutch collar allows you to select the appropriate torque setting for driving screws. Rotate the collar to align the desired number with the arrow on the tool body. Lower numbers are for smaller screws and softer materials, while higher numbers are for larger screws and harder materials. The drill symbol setting bypasses the clutch for maximum torque when drilling.

5.4 Forward/Reverse Control

The forward/reverse button is located above the trigger. Push the button to the left for forward rotation (drilling/driving) and to the right for reverse rotation (removing screws or backing out bits). Center position locks the trigger for safety.

5.5 LED Work Light

The integrated LED light illuminates the work surface. It has 3 positions and 3 modes, providing up to 70 Lumens. The spotlight mode includes a 20-minute shutoff function for extended illumination.
