STEP 3
Gently remove the air filter by pressing the blue / green
rubber seal to the right, which will unseat it from
the filter housing. Pull it towards you to remove the
old filter;
STEP 4
Inspect the carburetor to make sure it is clean� If it is
coated with oil and dirt, use a carburetor cleaner spray
to remove any oil and dirt residue;
If the batteries will be removed, this should be accomplished by a
qualified technician. We do not recommend battery removal by the
owner / operator as the batteries installed in the coach are very heavy
and require special handling for their safe and proper removal and
re-installation�
DANGER
Do not smoke or allow any fire, flame, spark, or other
ignition sources around the battery area. Do not disconnect
battery cables while the generator set is cranking or running.
Batteries gasses are explosive, which can result in severe
burns and physical injuries or death.
WARNING
When working with batteries wear the proper personal
protection equipment (rubber gloves, goggles, and a protective
apron). The battery electrolyte solution if spilled / splattered
can cause severe eye damage and burns to the skin.
■ Spark Plug
Replace the generator’s spark plug after 200 hours or prior to storage
as specified in the Onan QG 2500 LP Generator Manual’s Periodic
Maintenance Schedule� Once the spark plug is removed be sure to
inspect it for wear. Verify the spark plug gap (0.0250 in. (0.64 mm)
and adjust if necessary, prior to re-installation� Note the following:
1. Black deposits indicate a rich mixture�
2. Wet spark plugs indicate misfiring and possible oil fouling.
3. Badly or frequently fouled spark plugs indicate the need for
a major tune-up�
■ Carburetor Governor Linkage
Inspect and ensure the carburetor governor linkage is free to move
through its entire range of travel� The governor linkage should be
cleaned and adjusted by an ONAN Service Center as specified in the
Periodic Maintenance Schedule (monthly or after 100 hours).

GENERATOR SET STORAGE
When the generator set is not in use greater than 120 days, the
generator performance may degrade and effect the life of the engine�
The following procedure is recommended to keep the generator
set running efficiently after periods of storage:
STEP 1
Disconnect the load, switch the generator’s AC breaker
off and stop the generator;
STEP 2
Close the fuel supply valve and remove the air filter.
Restart the generator set at the set control� As the
generator set starts to run out of fuel (noticeable
stumble or surge), spray a storage fogger, such
as OnaGard™, into the carburetor intake and then
replace the air filter. Follow the manufacturer’s
instructions for using the fogger. (See air filter
procedure above for filter removal and replacement);
STEP 3
Replace the air filter after the engine stops. Remove
the spark plug and ground the spark plug lead to
prevent arcing� Spray OnaGard™ or engine oil into
the spark plug hole while cranking the engine for 3
seconds� Wipe away any excess oil and re-install the
spark plug and the spark plug wire� (See spark plug
procedure); and,
STEP 4
Drain the crankcase oil when the exhaust system
has cooled following the procedures above. Refill the
crankcase with clean oil�
RETURNING THE GENERATOR SET TO OPERATION
Follow these steps to place the generator back into service
following long term storage:
STEP 1 Inspect and clean the generator set;
STEP 2
Check the engine oil and viscosity to ensure it is
correct for the existing environment and temperature�
Replace the oil if necessary;
STEP 3
Inspect and clean the battery terminals and connectors
if necessary;
STEP 4
Inspect the air filter for cleanliness and replace if
necessary;
STEP 5 Turn on the fuel supply;
