Setup

Before operating the hammer drill, ensure it is properly set up for your task.

1. Attach Auxiliary Handle: Loosen the auxiliary handle clamp, slide the handle onto the tool's neck, and tighten it in a comfortable position for two-handed operation.
2. Install Depth Stop: Insert the metal depth stop into the designated hole on the auxiliary handle. Adjust its length according to your desired drilling depth and secure it.
3. Insert SDS-Plus Bit:
   • Clean the shank of the drill bit.
   • Apply a thin layer of grease to the bit shank.
   • Push the bit into the SDS-Plus chuck until it locks into place. Pull on the bit to ensure it is securely seated.
4. Select Function: Use the function selector switch to choose the appropriate mode:
   • Drilling: For drilling in wood, metal, or plastic without impact.
   • Hammer Drilling: For drilling in concrete, masonry, or stone with impact.
   • Chiseling (with lock): For light chiseling work where the chisel position needs to be fixed.
   • Chiseling (without lock): For chiseling work where the chisel can rotate freely.

Operation

Follow these steps for safe and effective operation of your Einhell rotary hammer drill.

1. Connect to Power: Plug the tool into a suitable 230V power outlet.
2. Adjust Speed: Use the speed control dial to set the desired rotation speed. Lower speeds are suitable for larger diameters or harder materials, while higher speeds are for smaller diameters or softer materials.
3. Start Drilling/Chiseling:
   • Position the tool firmly against the workpiece.
   • Press the trigger switch to start the tool.
   • For continuous operation, press the trigger and then engage the continuous operation lock button. To disengage, press the trigger again.
   • Apply steady, even pressure. Do not force the tool.
4. Stopping the Tool: Release the trigger switch. If the continuous operation lock is engaged, press the trigger briefly to release it, then release the trigger.
5. Changing Direction: The tool features a rotation direction switch, typically located near the trigger. Ensure the tool is stopped before changing the direction of rotation.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your rotary hammer drill.

• Cleaning: After each use, clean the tool housing with a soft, damp cloth. Do not use harsh cleaning agents or solvents. Keep ventilation openings clear of dust and debris.
• Chuck Maintenance: Regularly clean the SDS-Plus chuck and apply a small amount of grease to the moving parts to ensure smooth bit changes and prevent wear.
• Carbon Brushes: If the motor sparks excessively or the tool's performance decreases, the carbon brushes may need inspection or replacement. This should ideally be done by qualified personnel.
• Storage: Store the tool in its E-Box M40 transport and storage case in a dry, secure place, out of reach of children.
