4. Setup

4.1 Bit Installation (SDS-MAX)

1. Ensure the tool is unplugged from the power source.
2. Clean the bit shank and apply a small amount of bit grease to the shank.
3. Pull back the tool holder cover and insert the SDS-MAX bit into the chuck. Rotate the bit slightly until it engages.
4. Release the tool holder cover. Pull on the bit to ensure it is securely locked in place.

4.2 Handle Adjustment

The HR4013C comes with two types of auxiliary handles: a straight handle and a D-handle. Choose the handle that best suits your application.

1. Loosen the handle clamp.
2. Adjust the handle to the desired position for optimal control and comfort.
3. Tighten the handle clamp securely.

4.3 Power Connection

Connect the tool's power cord to a grounded power outlet. For optimal performance and safety, use a 10-gauge extension cord up to 50 feet in length if needed.

5. Operating Instructions

5.1 Selecting Operating Mode

The HR4013C offers two operating modes:

• Hammer Only: For chipping, breaking, or demolition work.
• Hammer Drill: For drilling into concrete or masonry with rotation and hammering action.

To select a mode, rotate the mode selector switch located on the top of the tool to the desired icon.

5.2 Variable Speed Control

The tool features a variable speed control dial, allowing you to match the speed to the application. Adjust the dial from 1 (lowest speed) to 5 (highest speed) as needed.

5.3 Proper Drilling/Chipping Technique

1. Hold the tool firmly with both hands, maintaining good balance and safe footing.
2. Turn the tool on and apply enough pressure to prevent it from bouncing uncontrollably. Do not press excessively hard, as this will not increase efficiency.
3. Allow the tool to do the work. Do not force it.
