4. Setup

4.1 Connecting to Air Supply

1. Ensure your air compressor is off and depressurized.
2. Attach the threaded cap fitting to the air inlet of the chisel hammer.
3. Connect a suitable air hose (recommended diameter: 9mm) to the fitting.
4. Ensure all connections are secure to prevent air leaks.
5. Turn on your air compressor and adjust the pressure regulator to the recommended operating pressure (max 6.3 bar).

4.2 Installing Chisels

1. Disconnect the tool from the air supply.
2. Slide the retaining spring over the chisel shank.
3. Insert the 10mm hexagonal shank of the desired chisel into the tool's chuck. The hexagonal shaft prevents rotation during use.
4. Push the chisel firmly until it clicks into place and is held securely by the retaining spring.
5. Reconnect the air supply.

5. Operating Instructions

5.1 Basic Operation

1. Ensure the chisel is properly installed and the air supply is connected and at the correct pressure.
2. Hold the tool firmly with both hands, utilizing the rubberized grip for improved hold and reduced vibration.
3. Position the chisel tip against the material to be worked on.
4. Press the trigger to activate the hammer. The tool delivers 4500 impacts per minute for high impact power.
5. Apply steady, controlled pressure and guide the tool along the desired path.
6. Release the trigger to stop the operation.

5.2 Adjusting Power

The ABAC G-475 features an air regulation valve to adapt the impact power. Locate the valve (usually a knob or screw near the air inlet) and turn it to increase or decrease the airflow, thereby adjusting the tool's power output to suit the task.

Regular lubrication is crucial for the longevity and performance of your pneumatic tool. Use pneumatic tool oil (not included, but an empty bottle is provided for convenience).

1. Disconnect the tool from the air supply.
2. Add a few drops of pneumatic tool oil into the air inlet before each use.
3. Reconnect the air supply and run the tool for a few seconds to distribute the oil.
4. The included mini lubricator can be installed in-line with your air hose for automatic lubrication.

6.2 Cleaning and Storage

• After each use, disconnect the air supply and clean the tool and chisels of any debris, dust, or residue.
• Store the tool and accessories in the provided plastic carrying case in a dry, clean environment, away from direct sunlight and extreme temperatures.
