• Variable Speed Dial and Trigger: Allows matching the impact rate to the application.
• L.E.D. Service Light: Indicates when carbon brushes require replacement.
• L.E.D. Power Light: Illuminates to indicate switch failure or cord damage.

Setup

1. Unpacking and Inspection

Carefully remove the demolition hammer and all accessories from the packaging. Inspect the tool for any signs of damage. Ensure all included components are present: 12" Bull Point SDS-MAX bit, Hammer Bit Grease, wiping cloth, and tool case.

2. Attaching the Side Handle

Loosen the clamp on the side handle and slide it onto the tool's barrel. Adjust the handle to a comfortable position for your application and tighten the clamp securely.

3. Installing an SDS-MAX Bit

1. Clean the bit shank and apply a small amount of hammer bit grease (provided) to prevent premature wear.
2. Pull back the tool holder cover and insert the bit into the chuck.
3. Rotate the bit slightly until it engages with the locking mechanism.
4. Release the tool holder cover. Pull on the bit to ensure it is securely locked in place. A slight amount of play is normal for SDS-MAX systems.

The tool features 12 bit angle settings, allowing the bit to be set at different positions for optimal operator comfort and access to various work angles.

Operating Instructions

1. Power Connection

Connect the tool to a standard 120V AC power outlet. Ensure the power cord is not damaged and is routed safely to avoid tripping hazards.

2. Adjusting Speed

Figure 3: Variable speed control dial. This image shows the dial used to adjust the impact rate of the demolition hammer, allowing users to match the speed to the specific application.

The HM1213C features a variable speed control dial and trigger. Rotate the dial to select the desired impact rate. Lower speeds are suitable for delicate work or starting holes, while higher speeds are for maximum demolition power. The constant speed control automatically applies additional power to the motor to maintain speed under load.

3. Starting and Stopping

To start the tool, press the power trigger. The soft start feature suppresses start-up reaction for more precision. For continuous operation, engage the lock-on button. To stop, release the trigger or press the lock-on button again if engaged.

4. Demolition Operation

Hold the tool firmly with both hands, utilizing the main handle and the adjustable side handle. Apply steady, downward pressure. Allow the tool to do the work; excessive force is not necessary and can reduce efficiency and increase user fatigue. The Anti-Vibration Technology (AVT) system, with its internal counterbalance and vibration-absorbing rear handle, significantly reduces felt vibration during operation.

Maintenance

1. Carbon Brush Replacement

Figure 6: LED service light indicator. This image shows the LED light that illuminates approximately 8 hours before the carbon brushes need replacement, ensuring timely maintenance.

The L.E.D. service light will illuminate approximately 8 hours before the carbon brushes need replacement. Replace both carbon brushes simultaneously. Refer to the detailed instructions in the full user guide for the correct procedure or contact an authorized service center.

An automatic brush cut-off feature protects the commutator from damage, extending tool life.

2. Cleaning and Lubrication

Regularly clean the tool's ventilation openings to prevent overheating. Wipe down the exterior with a damp cloth. Apply hammer bit grease to the SDS-MAX bit shanks before each use to ensure smooth operation and reduce wear.

3. Storage

Store the tool in its case in a clean, dry place, out of reach of children and unauthorized users.

Troubleshooting

For issues not listed or if solutions do not resolve the problem, contact a Makita authorized service center.
