4. Setup

Follow these steps to prepare your rotary hammer drill for operation:

1. Attaching the Auxiliary Handle:

   Slide the auxiliary handle onto the tool's neck. Rotate it to your desired working position for optimal control and comfort. Tighten the handle securely by twisting its base until it is firm.

   

2. Inserting SDS-Plus Accessories:

   Pull back the SDS-Plus chuck sleeve. Insert the desired SDS-Plus drill bit or chisel into the chuck until it clicks into place. Release the sleeve. Gently pull on the accessory to ensure it is securely locked and cannot be easily removed.

   

3. Setting the Depth Gauge:

   Insert the depth gauge into its designated holder on the auxiliary handle. Adjust the gauge to the required drilling depth. Secure it in position to ensure consistent drilling depth.

5. Operating Instructions

Understand the different functions and controls of your rotary hammer drill for effective use.

1. Function Selection:

   Rotate the 4-function knob located on the side of the tool to select the appropriate operating mode:

   • Drilling Mode: For drilling into wood, steel, and other non-masonry materials.
   • Hammer Drilling Mode: Combines rotation and hammering action for efficient drilling into concrete, masonry, and stone.
   • Chiseling Mode: Provides hammering action without rotation for chiseling, chipping, or breaking concrete and brick.
   • Chisel Position Adjustment Mode: Allows you to rotate and lock the chisel into the desired working angle before engaging chiseling mode.

   

2. Variable Speed Control:

   The tool features a variable speed trigger and a 6-level speed adjustment dial. Press the trigger to start the tool, and vary the pressure for different speeds. Use the dial to set a maximum speed limit for specific applications.

   

3. Lock Button:

   For extended periods of operation, press the lock button while the trigger is engaged to maintain a constant speed. This reduces user fatigue. To release, simply press the trigger again.

4. Safety Clutch:

   The integrated safety clutch is a protective feature. If the drill bit or chisel jams during operation, the clutch will disengage the drive to prevent excessive torque feedback to the user, protecting your wrist and the tool.

   

5. Working with the Auxiliary Handle:

   The auxiliary handle provides additional stability and control, especially during heavy-duty tasks or when working in awkward positions. Always use it for two-handed operation.

   

6. Lightweight Design for Overhead Work:

   The tool's lightweight design (3.3 kg) facilitates overhead tasks, such as drilling into ceilings, reducing user fatigue during prolonged use.

   

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your tool.

• Cleaning: Regularly clean the tool's exterior and especially the ventilation slots to prevent dust and debris buildup. A clean tool dissipates heat more efficiently.
• Anti-Dust Structure and Heat Exhaust: The tool features a double-layer bottom structure for anti-dust protection and an efficient heat exhaust system to protect the motor. Keep these areas clear.



• Carbon Brushes: The tool includes replaceable carbon brushes. If the tool's performance decreases or it stops working, the carbon brushes may need inspection or replacement. Refer to the detailed product manual for specific instructions on how to access and replace them.
• Storage: Store the tool and all accessories in the provided storage case in a dry, secure location, away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your ENEACRO Rotary Hammer Drill, refer to the following common troubleshooting tips:

• Tool Not Starting:
  • Check if the power cord is securely plugged into a functional outlet.
  • Ensure the ON/OFF switch is in the 'ON' position.
  • Inspect the power cord for any visible damage.
• Reduced Performance or Lack of Power:
  • Verify that the correct function mode (Drilling, Hammer Drilling, Chiseling) is selected for the task.
  • Check if the drill bit or chisel is properly inserted and secured in the SDS-Plus chuck.
  • Inspect the carbon brushes for wear. Worn brushes can lead to intermittent power or reduced motor efficiency.
• Excessive Vibration or Unusual Noise:
  • Ensure the accessory (drill bit/chisel) is not bent, damaged, or improperly installed.
  • Check for loose components on the tool.
• Overheating:
  • Ensure the heat vents are clear of dust and debris.
  • Avoid continuous heavy-duty operation without allowing the tool to cool down.
  • Reduce the load on the tool if it consistently overheats.

If these steps do not resolve the issue, please contact customer support.
