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.
