Important Safety Information

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

• Work Area Safety: Keep your 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.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not expose power tools to rain or wet conditions. A corded electric drill requires a proper power source.
• Personal Safety: Always wear eye protection. Use hearing protection when operating for extended periods. Dress properly; avoid loose clothing or jewelry. Secure long hair.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
• Service: Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Setup

Attaching the Side Handle

The side handle provides improved control and stability, especially during hammer drilling or when drilling larger holes.

• Loosen the side handle by rotating it counter-clockwise.
• Slide the handle onto the front of the drill body, positioning it to your preferred angle for comfortable operation.
• Tighten the handle by rotating it clockwise until it is securely fastened.

Inserting and Changing Drill Bits

The 1/2-inch keyless chuck allows for quick and easy bit changes without the need for a chuck key.

1. Ensure the drill is unplugged from the power source.
2. Grip the rear collar of the chuck with one hand and rotate the front collar counter-clockwise with the other hand until the chuck jaws are open wide enough to accept the drill bit.
3. Insert the drill bit fully into the chuck.
4. Tighten the chuck by gripping the rear collar and rotating the front collar clockwise until the bit is securely clamped. A firm hand-tightening is usually sufficient for the keyless chuck.

Setting the Depth Rod

The depth rod helps to drill holes to a consistent, predetermined depth.

• With the drill bit inserted, loosen the side handle.
• Slide the depth rod through the hole in the side handle.
• Adjust the rod so that the tip of the drill bit is the desired distance from the end of the rod.
• Tighten the side handle to secure the depth rod in place.

Operating Instructions

Powering On/Off and Variable Speed

• To start the drill, depress the variable speed trigger. The speed of the drill is controlled by how far the trigger is pressed.
• For continuous operation, depress the trigger fully and then press the lock-on button. To release, depress the trigger again.
• To stop the drill, release the trigger.

Selecting Drill Mode or Hammer Drill Mode

The DR670 features a mode selector to switch between standard drilling and hammer drilling functions.

• Drill Mode: Use for drilling into wood, metal, plastics, and other non-masonry materials. Set the mode selector to the drill icon.
• Hammer Drill Mode: Use for drilling into masonry materials such as brick, concrete, and stone. Set the mode selector to the hammer icon. This mode combines rotary action with a hammering action for faster penetration into hard materials.

• Cleaning: After each use, wipe the tool with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep ventilation openings clear of dust and debris.
