Introduction
This manual provides essential information for the safe and efficient operation, setup, and maintenance of your Generac GP6500 portable generator. The GP6500 is designed to provide reliable power with PowerRush Advanced Technology, offering increased starting capacity for various applications.
Consignes de sécurité
Always operate the generator outdoors in a well-ventilated area, away from windows and doors, to prevent carbon monoxide poisoning. Never operate the generator indoors, including garages or sheds.
- COSense Technology: This generator is equipped with COSense Technology, which automatically shuts down the engine if hazardous carbon monoxide levels are detected.
- Arrêt pour niveau d'huile bas : The engine will automatically shut down if the oil level drops below a safe operating threshold, protecting the engine from damage.
- Disjoncteurs: Integrated AC circuit breakers protect the generator from overload. Reset them by pressing the button after resolving the overload condition.
Installation
1. Déballage et montage
Carefully remove the generator and all components from the packaging. Assembly typically involves attaching the wheels and the easy fold-down handle. Refer to the included assembly guide for detailed steps.

2. Ajout d'huile moteur
The generator is shipped without engine oil. Locate the oil fill cap/dipstick. Using the provided funnel, carefully add the recommended engine oil (typically 10W-30, a quart is often included with the generator) until it reaches the 'Full' mark on the dipstick. Do not overfill.

3. Ajouter du carburant
Fill the large-capacity steel fuel tank with fresh, unleaded gasoline. Ensure the fuel cap is securely tightened after filling. The built-in fuel gauge allows for easy monitoring of fuel levels.
Mode d'emploi
1. Démarrage du générateur
- Assurez-vous que le générateur est placé sur une surface plane et que toutes les charges électriques sont déconnectées.
- Tournez le robinet d'essence sur la position « ON ».
- Move the choke lever to the 'CHOKE' position (if starting a cold engine).
- For electric start models, press and hold the 'START' button until the engine starts. For manual start, pull the recoil starter handle firmly.
- Une fois le moteur démarré, déplacez progressivement le levier de starter en position « MARCHE ».
2. Connexion des charges électriques
Once the generator is running smoothly, you can connect your electrical devices to the appropriate outlets (120V, 240V). Do not overload the generator. The control panel features multiple outlets with protective covers.

- Débranchez toutes les charges électriques du générateur.
- Laisser tourner le moteur à vide pendant quelques minutes pour le refroidir.
- Mettez l'interrupteur du moteur sur la position « ARRÊT ».
- Tournez le robinet d'essence sur la position « ARRÊT ».
Entretien
Regular maintenance ensures the longevity and optimal performance of your generator. Always refer to the complete owner's manual for detailed maintenance schedules and procedures.
- Changements d'huile : Change the engine oil at recommended intervals, typically after the first 20 hours of operation, and then every 50-100 hours or annually, whichever comes first. Use the hour meter to track usage.
- Filtre à air : Inspectez et nettoyez régulièrement le filtre à air. Remplacez-le s'il est endommagé.
- Bougie d'allumage: Inspect and clean the spark plug annually or every 100 hours. Replace if necessary.
- Système d'alimentation en carburant : Use a fuel stabilizer if storing the generator for extended periods to prevent fuel degradation.
- Nettoyage général : Gardez le générateur propre et exempt de débris.
Dépannage
If your generator experiences issues, consult the following basic troubleshooting steps. For complex problems, contact qualified service personnel.
| Problème | Cause possible | Solution |
|---|---|---|
| Le moteur ne démarre pas | No fuel, low oil, choke not set, battery low (electric start) | Add fuel, add oil, adjust choke, charge battery. |
| Aucune puissance de sortie | Disjoncteur déclenché, surcharge, connexion défectueuse | Réarmez le disjoncteur, réduisez la charge, vérifiez les connexions. |
| Le moteur s'arrête pendant le fonctionnement | Low oil, COSense activation, overload | Check oil level, move to well-ventilated area, reduce load. |
