Performing Fuel System Leak Test
All products are factory-tested before shipping to verify
the performance and integrity of the fuel system. How-
ever, it is important to perform a final fuel system leak test
before starting the generator. The entire fuel system
should be tested from supply to regulator.
See Figure 4-12. Perform a final fuel system leak test
after generator installation. The test will identify possible
leaks at all connection points (A).
It is best practice to perform a fuel system leak test
during normally-scheduled maintenance.
Figure 4-12. Connection Points to Leak Check
Inspect for leaks by spraying all connection points with a
non-corrosive gas leak detection fluid. The solution
should not be blown away or form bubbles.
Attention After Submersion
DO NOT start or operate generator if it has been sub-
merged in water. Have an IASD thoroughly clean, dry,
and inspect generator following any submersion in water.
If the structure (home) has been flooded, it should be
inspected by a certified electrician to verify there will not
be any electrical problems during generator operation or
when utility power is returned.
Corrosion Protection
Regular scheduled maintenance should be conducted to
inspect unit for corrosion. Inspect all metal components
of generator, including base frame, brackets, alternator
can, the entire fuel system (inside and outside of the gen-
erator), and fastener locations. If there is corrosion found
on generator components (e.g. regulator, engine/alterna-
tor mounts, fuel plenum, etc.), replace parts as neces-
sary.
Periodically wash and wax enclosure using automotive
type products. Do not spray unit with a hose or power
washer. Use warm, soapy water and a soft cloth. Fre-
quent washing is recommended in salt water/coastal
areas. Spray engine linkages with a light oil such as WD-
40.
Remove From and Return To Service
Procedure
Remove From Service
If generator cannot be exercised monthly, at a minimum,
and will be out of service longer than 90 days, proceed as
follows to prepare generator for storage:
1. Start engine and allow it to warm up.
2. Close fuel shutoff valve in fuel supply line and
allow engine to stop.
3. Set generator MLCB (generator disconnect) to
OFF (OPEN) once engine has stopped.
4. Disconnect battery charger AC input T1/Neutral
cable (with white sleeve) at controller.
5. Remove 7.5A fuse from generator control panel.
6. Disconnect battery cables. Remove negative bat-
tery cable first.
7. Drain oil completely while engine is still warm, and
then fill crankcase with oil. See Changing the Oil
and Oil Filter.
8. Attach a tag to engine indicating viscosity and clas-
sification of the new oil in the crankcase.
9. Remove spark plug(s) and spray a fogging agent
into spark plug(s) threaded openings. Install and
tighten spark plug(s) to specification.
10. Remove battery and store in a cool, dry place.
11. Clean and wipe down generator enclosure.

DANGER
Explosion and fire. Fuel and vapors are extremely
flammable and explosive. No leakage of fuel is
permitted. Keep fire and spark away. Failure to do
so will result in death or serious injury.

Explosion. Batteries emit explosive gases.
Always disconnect negative battery cable
first to avoid spark. Failure to do so could
result in death or serious injury.
