3. Setup and Assembly

Follow these steps to set up your RUBI DC-250 Python 850 saw for operation.

1. Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
2. Leg Assembly: Unfold the legs and ensure they are securely locked into position. The integrated wheels facilitate moving the saw to your desired location.
3. Table Installation: Place the removable cutting tables onto the main frame. Ensure they are properly seated and stable.
4. Water Reservoir: Fill the water reservoir with clean water. Ensure the C3 Python cooling system hose is properly connected to the pump and directed towards the blade.
5. Blade Installation (if not pre-installed): Refer to the blade manufacturer's instructions for proper installation. Ensure the blade is securely fastened and the blade guard is in place.
6. Power Connection: Connect the saw to a 120 V - 60HZ power supply. Ensure the power outlet is grounded and capable of handling the saw's power requirements.
7. Adjusting the Square: Adjust the aluminum square to the desired angle (0° to 60°) for your specific cutting needs. Use the lateral stop for repetitive cuts.

4. Operating Instructions

This section details the procedures for operating your electric cutter and miter saw.

4.1. General Cutting Procedure

1. Preparation: Ensure the saw is on a stable, level surface. Verify the water reservoir is filled and the cooling system is ready.
2. Material Placement: Place the tile or material to be cut firmly against the adjustable square. Ensure the cutting line is aligned with the blade's path.
3. Power On: Turn on the saw using the main power switch. Allow the blade to reach full speed before beginning the cut.
4. Engage Cooling System: Activate the C3 Python cooling system. Adjust the water flow to ensure direct impact on the cutting point, optimizing cooling and dust suppression.
5. Making the Cut: Slowly and steadily guide the motor assembly along the sliding bearings through the material. Do not force the cut. Maintain a consistent feed rate.
6. Completion: Once the cut is complete, retract the motor assembly. Turn off the saw and the cooling system. Wait for the blade to stop completely before removing the cut material.

4.2. Miter Cuts (45° Angle)

The motor assembly can be folded at 45° for miter cuts. To perform a miter cut:

1. Adjust Motor Assembly: Unlock and pivot the motor assembly to the 45° position. Securely lock it in place.
2. Adjust Square: Position the adjustable aluminum square to guide the material for the desired miter angle.
3. Cutting: Follow the general cutting procedure, ensuring the material is stable and the blade clears the table at the adjusted angle.

4.3. ZERO DUST System

The patented ZERO DUST system significantly reduces respirable dust particles. Ensure the C3 Python cooling system is properly engaged and water flow is optimized to maximize the effectiveness of this system.

5. Maintenance

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

5.1. Cleaning

• After Each Use: Disconnect power. Remove the removable tables and clean off all debris, slurry, and water residue.
• Water Reservoir: Regularly drain and clean the water reservoir to prevent buildup of sediment and algae, which can clog the cooling system.
• Sliding Bearings: Keep the motor assembly's sliding bearings clean and free of debris to ensure smooth operation.
• Blade Guard: Clean the blade guard to maintain visibility and ensure proper function.

5.2. Blade Care and Replacement

• Inspection: Regularly inspect the blade for wear, cracks, or damage. A dull or damaged blade can affect cutting performance and safety.
• Replacement: When replacing the blade, always disconnect the saw from power. Follow the blade manufacturer's instructions and ensure the new blade is compatible with the saw.

5.3. General Inspection

• Cables and Connections: Check power cords and water hoses for any signs of wear or damage.
