1. Power Connection: Plug the machine into a 220V / 50HZ power outlet. Ensure the water pump is also plugged in and submerged in water.
2. Starting the Machine: Hold the machine firmly with both hands using the main and auxiliary handles. Press the power switch to start the motor. Allow the blades to reach full idling speed (7500 r/min) before beginning the cut.
3. Making a Cut: Gently guide the machine along the marked line on the wall. Apply steady, even pressure. Do not force the machine; let the blades do the work. The water pump will automatically supply water to the cutting area to reduce dust and cool the blades.
4. Cutting Technique: For optimal results, make multiple shallow passes rather than one deep cut, especially in hard materials. This reduces strain on the motor and blades. The 360° slotted design allows for efficient cutting without dead ends.
5. Stopping the Machine: Release the power switch to stop the motor. Wait for the blades to come to a complete stop before setting the machine down or performing any adjustments.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your wall chaser.

• Cleaning: After each use, unplug the machine and clean off any dust or debris from the housing, ventilation slots, and blade area. Use a damp cloth; do not use solvents.
• Blade Inspection: Regularly inspect saw blades for wear, damage, or dullness. Replace worn blades promptly to maintain cutting efficiency and safety.
• Carbon Brush Replacement: The machine features accessible carbon brush replacement. Check carbon brushes periodically and replace them when they are worn down to their limit marks. Refer to the labeled diagram for the carbon brush access point.
• Water Pump Care: Clean the water pump after each use to prevent clogging from debris. Ensure the water pipe is clear.
• Storage: Store the machine and its accessories in the provided carrying box in a dry, secure location, out of reach of children.
