The gasoline powered generator provides up to 2800 watts of power, enough to run all your appliances. MP
➜ Please be sure to operate the generator at half load or more (at least 1200 watts, either the heat pump or an electric
heater) for one hour every month. Failure to do this can lead to internal corrosion, gumming up of the float bowl, and
eventual failure. MP62
➜ The generator is NOT compatible with E-85 fuel. If the vehicle is equipped with a generator, avoid the use of
E-85 fuel. MP7
Use clean, fresh unleaded gasoline having a minimum octane rating (Anti-Knock Index) of 87.
Ethanol Blend - Not more than 10'
Methanol Blend - Not more than 5' corrosion inhibitors.
CAUTION: Using gasoline or gasoline additives containing more than 5% methanol can be corrosive to
fuel system components.

Hold the switch in its Start position to crank and start the generator set.
Press the switch to the Stop position to stop the generator set.
Hold the switch in its Stop position to prime the fuel system.
2 Status Indicator - LED in the control switch that blinks rapidly during preheat and cranking. Stays on continuously after
generator set is running. If the generator set shuts down abnormally, the indicator flashes a numerical code to indicate the
cause of the shutdown (see Chapter 5 on page 31).
3 Hour Meter - Records the total running time of the generator set. Cannot be reset.

Setting up the Generator, GenManual 14
Park the vehicle so that genset exhaust gases disperse away from the vehicle. Barriers such as walls, snow banks, high
grass, brush and other vehicles can cause exhaust gases to accumulate in and around the vehicle.
Do not operate power ventilators or exhaust fans while the vehicle is standing with the genset running. The ventilator or fan
can draw exhaust gases into the vehicle.
Always close the rear windows of the vehicle and turn off the roof ventilation fan to avoid exhaust
entering the vehicle's interior. MP?
Check all CO monitors to assure proper operation.
See below Generator Switch on Monitor Panel.

Wait 5 seconds for the control to reset before trying again. GenMan 14
After five tries, let the starter motor cool down for 30 seconds before trying again.GenMan 14
Allow the generator to run for a couple of minutes before turning on heavy loads such as the air
For top performance and engine life, especially in colder weather, let the engine warm up for two
minutes before connecting appliances. GenMan14
To STOP the generator, first shut down all heavy loads, let the generator run for a few minutes to cool down, then press the
STOP (bottom) side of the rocker switch. MP93 and GenManual14
Restarting the Genset, GenManual14 - If the genset shuts down, disconnect or turn off as many appliances as possible
and try restarting the genset. Reconnect only as many appliances as will not overload the genset or cause the circuit breaker
Loading the Genset, GenManual15
The genset can power AC motors, air conditioners, AC/DC converters and other appliances. How much appliance load* can
be powered depends upon the genset power rating. The genset will shut down or its circuit breakers will trip if the sum of the
loads exceeds genset power.
See Load Chart.

Monitor Panel - The hour meter keeps track of how many hours your generator has been running. This is important for
such as oil changes, etc. See your Cummings/Onan generator service manual for details. There is a break-in oil change after
the first 20 to 50 hours of use. You also need to exercise your generator every month by running it for an hour under
moderate load. MP93
In order to check the generator oil every 8 hours, you have to crawl under RV to check generator oil every 8 hours of use;
