Maintenance
During periods of extended storage:
1. Add a diesel fuel additive to the chassis fuel tank to prevent algae growth (only with a
diesel fueled generator).
2. Completely fill the chassis diesel fuel tank to prevent water condensation and rust in the
tank (only with a diesel fueled generator).
3. Cover the end of the generator exhaust pipe with screen to prevent bug and rodent
intrusion.
With the exception of simple items, such as normal maintenance (i.e., oil changes, etc.),
all service work should be done by an authorized repair facility. Improper adjustments can
damage the generator and electrical appliances and can result in a safety hazard. Follow the
generator owner’s manual for maintenance intervals and recommendations.
Exercising Your Generator
– When storing the generator for extended periods of time, it is
important to run the generator regularly to keep it in good working order. Lack of exercise
can cause moisture build-up in the fuel system resulting in poor performance.
For more information on generator operation and maintenance, refer to the generator own-
er’s manual.
CARBON MONOXIDE IS DEADLY! Do not run the generator when
your motorhome is indoors or in a confined space. Asphyxiation or carbon
monoxide poisoning hazards exist whenever generator exhaust gasses can ac-
cumulate.
MOVING PARTS AND ELECTRICITY can cause severe personal injury
or death. To reduce exposure to these hazards, always disable AGS (if so
equipped) before:
 Sleeping in vehicle, unless vehicle has a working CARBON MONOX-
IDE detector.
 Parking vehicle in garage or confined space.
 Parking vehicle for storage.
 Servicing vehicle for storage.
 Servicing generator.
 Servicing batteries.
 Servicing appliances or electrical systems.
 Fueling the vehicle.
DO NOT run the generator or use the AGS AUTO ON or QUIET ON
modes (if so equipped) when your RV is indoors or in a confined space.
Asphyxiation or carbon monoxide poisoning hazards exist whenever genera-
tor exhaust gasses can accumulate.
Excessive usage can overheat and damage the generator starter motor. Do not
engage the starter motor for more than 20 seconds at a time. If the generator
doesn’t start after the first attempt, wait at least two minutes before beginning
another start sequence. If the generator does not start after a third attempt,
refer to the generator owner’s manual for additional information.
