When Calling for Assistance
The home generator system is designed for long term service as a backup generator. There is no need to take any storage
precautions. However, if it becomes necessary to take the system out of service for an extended period, call Technical
Services at 800 732-2989, between 8:00 AM and 5:00 PM CT for specific recommendations.
Storage
Clean Air Cooling System and Oil Cooler Fins
Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial engine disassembly.
Unobstructed air flow is critical for correct generator operation. For this reason, we recommend you have an authorized
service dealer clean the cooling system per recommended intervals (see Maintenance Schedule in the Maintenance
section). Equally important is to keep top of engine free from debris. Make sure the oil cooler fins are free of dirt and debris.
Also see Cleaning.
