Six Essential Tips for Proper Use of Small Gasoline Generators  

To ensure safe and efficient operation, here are six key recommendations for using small gasoline generators:  

1. Starting and Stopping the Engine  

Starting:  

- Turn the fuel valve to "ON."  

- Adjust the choke.  

- Gently push the throttle lever to the left.  

- Start the engine:  

  - Recoil start: Turn the engine switch to "ON," pull the starter handle until resistance is felt, then pull quickly. Avoid sudden rebounds.  

  - Electric start: Turn the switch to the start position (hold for ≤5 seconds). If unsuccessful, wait 10 seconds before retrying. After starting, move the choke to "OPEN" and adjust the throttle.  

Stopping:  

- For emergencies, turn the engine switch to "OFF."  

- Normal shutdown:  

  1. Close the throttle (push lever to the right).  

  2. Turn the engine switch to "OFF."  

  3. Turn the fuel valve to "OFF."  

Always refer to the manual for model-specific instructions.*  

2. Ignition System  

- Battery ignition: Use a 12V/35A+ battery. Connect positive first, then negative; disconnect in reverse. Ground the generator properly.  

- Magneto ignition: Check breaker point gap (0.02–0.05mm). Clean contacts with sandpaper if dirty. Test spark (6–8mm, blue-white preferred).  

3. Generator Wiring  

- Avoid overloading or connecting to household circuits.  

- If no output due to lost residual magnetism, briefly apply ~6V DC to the exciter winding (remove once voltage restores).  

4. Air Intake & Exhaust  

- Air filter: Never run the engine without it. Clean/replace:  

  - *Paper filter:* Replace if dirty or damaged.  

  - *Oil-bath filter:* Wash with detergent, dry, and re-oil (avoid excess oil to prevent smoke).  

- Throttle: Adjust for optimal air-fuel mix (lean = unstable; rich = smoke/sluggishness).  

- Exhaust: Remove carbon deposits from the muffler periodically.  

5. Fuel & Lubrication  

- Fuel: Use automotive gasoline. Filter while refueling (e.g., with medical gauze). Refuel only when the engine is cool in a ventilated area.  

  - *Carburetor adjustment:* Main jet (base) and idle jet (top). Turn in to lean, out to enrich. Ideal mixture (α = 0.4–1.4).  

- Oil: Use 4-stroke or SG/SF-grade oil (e.g., SAE 10W-30). Check levels with the dipstick; change oil regularly.  

6. Cylinder & Piston Maintenance  

- Clean carbon deposits from the spark plug. Adjust gap per manual (e.g., 0.7–0.8mm for KIPOR, 0.3–0.4mm for LD75). Tighten securely to prevent overheating.  

*Follow these guidelines to extend your generator’s lifespan and prevent accidents.*
