Setup

Follow these steps to prepare your concrete saw for operation.

1. Blade Installation

1. Ensure the saw is turned off and the spark plug cap is disconnected to prevent accidental starting.
2. Loosen the bolts securing the blade guard and remove it if necessary to access the blade arbor.
3. Place the circular saw blade onto the arbor, ensuring the rotation direction indicated on the blade matches the arrow on the saw.
4. Secure the blade with the appropriate washers and nut. Tighten firmly using the provided wrench.
5. Reattach and secure the blade guard, ensuring it covers the blade adequately for safety.

2. Fuel Mixing and Filling

1. This is a 2-stroke engine. Mix unleaded gasoline with 2-stroke engine oil at a ratio of 25:1 (Gasoline:Oil). Use the provided fuel mixing barrel for accurate measurement.
2. Shake the mixture thoroughly before pouring.
3. Using the priming funnel, carefully pour the fuel mixture into the fuel tank. Do not overfill.
4. Securely close the fuel tank cap.

3. Water Hose Connection

1. Connect the provided water hose to a water source and to the saw's water inlet.
2. Ensure the water valve is easily accessible to control water flow during operation.

Operating Instructions

Familiarize yourself with the controls and follow these steps for safe operation.

1. Starting the Engine

1. Place the saw on a flat, stable surface.
2. Ensure the ignition switch is in the "ON" position.
3. Engage the choke lever (if cold start).
4. Press the primer bulb several times until fuel is visible in the return line.
5. Pull the starter rope firmly and steadily until the engine attempts to start.
6. Once the engine fires (or after a few pulls), disengage the choke.
7. Continue pulling the starter rope until the engine runs smoothly.
8. Allow the engine to warm up for a few moments before beginning work.

2. Cutting Procedure

1. Before cutting, open the water valve to ensure a steady flow of water to the blade. This is crucial for blade cooling and dust suppression.
2. Hold the saw firmly with both hands, maintaining a balanced stance. The wrap-around front handle and rubber grip are designed for comfort and control.
3. Engage the throttle to bring the blade up to full operating speed.
4. Slowly and steadily guide the blade into the material. Do not force the saw; let the blade do the work.
5. The saw features two directional rubber wheels on the bottom to assist with movement and reduce effort during long cuts.
6. Adjust the cutting depth as needed. The maximum cutting depth is 12 cm (4.7 inches).
7. For continuous operation, it is recommended to idle the saw for 30 seconds after 30 minutes of continuous work, then stop it for 30 seconds. This helps extend the product's service life.
8. After completing the cut, release the throttle and allow the blade to stop rotating completely before setting the saw down.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your concrete saw.

• Cleaning: After each use, clean the saw thoroughly, removing dust and debris from the engine cooling fins, air filter, and blade area.
• Air Filter: Inspect and clean the air filter regularly. A clogged air filter can reduce engine performance and lead to overheating.
• Spark Plug: Check the spark plug periodically for wear and proper gap. Replace if necessary.
• Blade Inspection: Regularly inspect the saw blade for wear, cracks, or damage. Replace worn or damaged blades immediately.
• Fuel System: If storing the saw for an extended period, drain the fuel tank to prevent fuel degradation and carburetor issues.
• General Inspection: Check all nuts, bolts, and fasteners for tightness. Ensure all safety features are functioning correctly.

Troubleshooting

This section addresses common issues you might encounter. For problems not listed here, consult a qualified service technician.

• Engine Fails to Start:
  • Check if the ignition switch is in the "ON" position.
  • Ensure there is fresh, correctly mixed fuel in the tank.
  • Verify the choke is engaged for cold starts and disengaged after the engine fires.
  • Check the spark plug for fouling or damage.
  • Ensure the primer bulb is properly primed.
• Loss of Power / Engine Stalling:
  • Inspect the air filter for clogging and clean or replace if necessary.
  • Ensure the fuel mixture is correct (25:1 gasoline to oil).
  • Check for proper blade rotation and ensure the blade is not dull or damaged.
  • Allow the engine to cool down if it has been running continuously for an extended period.
• Excessive Vibration:
  • Check if the blade is properly installed and tightened.
  • Inspect the blade for damage or warping.
  • Ensure all mounting bolts are secure.
• Blade Breaking (Dry Use Warning):
  • The blade is susceptible to breaking if used without water. Always ensure a continuous water supply during cutting operations.
