Sikkerhedsoplysninger
Prioritér altid sikkerheden, når du bruger generatoren. Manglende overholdelse af sikkerhedsinstruktionerne kan resultere i alvorlig personskade eller død.
- Kuliltefare: Never operate the generator indoors or in partially enclosed areas. Generators produce carbon monoxide, an odorless, colorless, and deadly gas. Use a battery-powered carbon monoxide alarm.
- Brandfare: Fuel is highly flammable. Do not refuel while the engine is running or hot. Store fuel in approved containers away from ignition sources.
- Fare for elektrisk stød: Brug ikke generatoren i våde forhold. Sørg for, at alle forbindelser er sikre og korrekt jordforbundet.
- Varme overflader: Generatorens motor og lyddæmper bliver meget varme under drift og forbliver varme i et stykke tid efter nedlukning. Undgå kontakt.
- Korrekt ventilation: Always operate the generator in a well-ventilated outdoor area.
Opsætning og indledende forberedelse
Sørg for, at generatoren er korrekt forberedt før første brug.
1. Udpakning og montering:
Carefully remove the generator from its packaging. Inspect for any shipping damage. Attach wheels and handles if not pre-assembled, following the instructions in the included quick start guide.
2. Påfyldning af motorolie:
The generator is shipped without engine oil. It is crucial to add the correct type and amount of oil before starting. Refer to the specifications section for oil type and capacity.
- Placer generatoren på en plan overflade.
- Find oliepåfyldningsdækslet/målepinden.
- Using a funnel, slowly add the recommended engine oil until it reaches the upper mark on the dipstick. Do not overfill.
- Sæt oliepåfyldningsdækslet sikkert på igen.

3. Tilslutning af batteriet:
Connect the battery terminals, ensuring correct polarity. Use the included battery tender to charge the battery fully before the first start and to maintain charge during storage.
4. Tankning af generatoren:
The XP4500iH operates on either gasoline or propane.
- Benzin: Use fresh, unleaded gasoline with an octane rating of 87 or higher. Fill the fuel tank carefully, avoiding spills. Do not fill past the fuel filter.
- Propan: Connect a standard 20lb (or larger) propane tank to the generator's propane inlet using the provided hose and regulator. Ensure all connections are tight.

- Parallelle porte: For connecting two XP4500iH units.
2. Start af generatoren:
Ensure the generator is on a level surface outdoors, away from windows and doors.
- Ensure the main breaker is in the "OFF" position.
- Select your desired fuel source (gasoline or propane).
- Press and hold the "ENGINE START" button, or use the remote start feature.
- Once the engine starts, allow it to warm up for a few moments.
- Flip the main breaker to the "ON" position to supply power to the outlets.
3. Connecting Electrical Devices:
Plug in your devices to the appropriate outlets. Do not overload the generator. Monitor the load level on the digital control center.

Opretholdelse
Regular maintenance ensures optimal performance and extends the life of your generator.
Vedligeholdelsesplan:
| Punkt | Frekvens | Handling |
|---|---|---|
| Motorolie | Hver 25 timer eller årligt | Check level before each use. Change oil. |
| Luftfilter | Hver 50 timer eller årligt | Rengør eller udskift. |
| Tændrør | Hver 100 timer eller årligt | Inspect and clean. Replace if necessary. |

Opbevaring:
Til langtidsopbevaring skal generatoren klargøres som følger:
- Drain the gasoline from the fuel tank and carburetor. Run the engine until it stops from lack of fuel.
- If using propane, disconnect the propane tank. Propane can be stored indefinitely in its tank.
- Skift motorolien.
- Remove the spark plug and add a small amount of engine oil into the cylinder. Pull the recoil cord a few times to distribute the oil, then reinstall the spark plug.
- Store the generator in a clean, dry area, covered to protect from dust and moisture. Keep the battery connected to the battery tender.
