Operating Procedure
| Step | Procedure |
|---|---|
| 1 | Place the suction hose into water and move it up and down until filled with water, then connect it to the pump inlet. |
| 2 | Connect the check valve to the outlet (arrow pointing toward the hose), then connect the hose. |
| 3 | Connect the auxiliary fuel line to the carburetor fuel line. Squeeze the fuel bladder until fuel reaches about 5 cm from the carburetor. |
| 4 | Start the engine according to the cold-start or hot-start procedure. |
Cold Start
| Setting | Position |
|---|---|
| Power Switch | ON |
| Choke | Half open |
| Throttle | 1/3 open |
Pull the starter rope gently 5–10 cm, then pull sharply until the engine starts.
Hot Start
| Setting | Position |
|---|---|
| Power Switch | ON |
| Choke | Fully open |
| Throttle | 1/3 open |
Pull the starter rope gently 5–10 cm, then pull sharply until the engine starts.
III. Common Faults and Troubleshooting
| Problem | Solution |
|---|---|
| Flooded cylinder, difficult starting | Remove spark plug, clean oil from electrode, pull starter until fuel is cleared, reinstall spark plug. |
| Carbon buildup on the spark plug | Remove the spark plug and gently scrape off carbon deposits. |
| Incorrect spark plug gap | Adjust the gap to 0.7–0.9 mm using a flat screwdriver. |
| Magneto no spark | Replace the ignition coil or adjust the magneto gap with a feeler gauge. |
IV. Precautions
| No. | Precaution |
|---|---|
| 1 | Stop for 5–10 minutes after every 4 hours of continuous operation. |
| 2 | During cold start, keep choke half open for about 3 minutes before fully opening. |
| 3 | Gently squeeze the fuel bladder; stop when the fuel is 5 cm from the hose end. Excessive squeezing may flood the cylinder. |
| 4 | Never run the pump dry without water; it may damage internal seals and cause leakage. |
| 5 | Carburetor adjustment: Tighten high/low-speed needles clockwise, then back both out about 1¾ turns, fine-tune during operation. |
