2. Sigurnosne informacije
Operating a generator safely is paramount. Failure to follow safety instructions can result in serious injury or death. Always prioritize safety during setup, operation, and maintenance.
- Opasnost od ugljičnog monoksida: Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas. Never operate the generator indoors or in partially enclosed areas. Always operate outdoors in a well-ventilated area, far from windows, doors, and vents.
- Opasnost od požara: Fuel is highly flammable. Never refuel while the engine is running or hot. Avoid spilling fuel on hot engine parts. Store fuel in approved containers in a well-ventilated area away from ignition sources.
- Opasnost od električnog udara: Ensure the generator is properly grounded before use. Do not operate the generator in wet conditions. Always use appropriate extension cords rated for outdoor use and the generator's power output.
- Zaštita od preopterećenja: The generator is equipped with overload protection. Do not exceed the generator's rated wattage. Overloading can damage the generator and connected devices.
- Low Oil Shut-off: The engine will automatically shut down if the oil level is too low to prevent damage. Regularly check and maintain the oil level.
3. Postavljanje
3.1 Raspakiranje i sklapanje
Carefully remove the generator and all components from the packaging. The wheel and handle kit is included for easy transportation. Attach the wheels and handles according to the assembly instructions provided in the full manual.
3.2 Dodavanje motornog ulja
The generator is shipped without engine oil. Locate the oil fill cap/dipstick. Using the included bottle of oil and a funnel, carefully add the recommended amount of SAE 10W-30 engine oil. Do not overfill. Refer to the oil alert indicator on the control panel.

Figure 2: Fuel tank and oil fill location.
3.3 Spajanje baterije
For electric start functionality, connect the battery terminals. Ensure connections are secure and correct polarity is observed (red to positive, black to negative).
3.4 Priključak goriva
- Benzin: Fill the 8.2-gallon fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not overfill.
- Propan (LPG): Connect the included 6-foot LPG hose to a propane tank and to the generator's propane inlet. Ensure all connections are tight to prevent leaks.
- Prirodni plin (NG): Connect a natural gas line to the generator using the included NG quick-connect adapter. An NG hose is not included and sold separately (part no. TF1450X-1431).

4. Upute za rad
4.1 Pokretanje generatora
- Provjerite je li generator na ravnoj površini i pravilno uzemljen.
- Turn the fuel valve to the ON position for gasoline or open the propane/natural gas supply.
- Select the desired fuel type using the fuel switch on the control panel.
- For electric start, insert the key and turn it to the START position. Hold until the engine starts.
- As a backup, a recoil starter is available. Pull the recoil cord firmly and steadily until the engine starts.
- Allow the generator to run for several minutes to warm up before connecting any devices.

6. Rješavanje problema
If your generator experiences issues, consult the following basic troubleshooting steps:
| Problem | Mogući uzrok | Otopina |
|---|---|---|
| Motor se ne pokreće | No fuel, low oil, spark plug issue, choke position | Check fuel level, add oil, inspect spark plug, adjust choke. |
| Nema izlazne snage | Isključen prekidač, preopterećenje, neispravan spoj | Resetirajte prekidače, smanjite opterećenje, provjerite spojeve. |
| Motor radi grubo | Ustajalo gorivo, prljavi filter zraka, problem sa svjećicom | Use fresh fuel, clean/replace air filter, inspect spark plug. |
For more complex issues or if troubleshooting steps do not resolve the problem, contact WEN customer support or a qualified service technician.
