Maintenance
Perform Leak Test
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.
All products are tested at the factory before shipping to
ensure the performance and integrity of the fuel system.
However, 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
4-7. 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 4-7. Connection Points to Leak Check
Check 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 the generator if it has been
submerged in water. Have an IASD thoroughly clean, dry,
and inspect the 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
perform a visual inspection of the unit for corrosion. Inspect
all metal components of the generator, including the base
frame, brackets, alternator can, the entire fuel system
(inside and outside of the generator), and fastener
locations. If there is corrosion found on generator
components (e.g. regulator, engine/alternator mounts, fuel
plenum, etc.), replace parts as necessary.
Periodically wash and wax the enclosure using automotive
type products. Do not spray the unit with a hose or power
washer. Use warm, soapy water and a soft cloth. Frequent
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 the generator cannot be exercised monthly, at a
minimum, and will be out of service longer than 90 days,
proceed as follows to prepare the generator for storage:
1. Start the engine and allow to warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the engine to stop.
3. Once the engine has stopped, set the generator
MLCB (generator disconnect) to OFF (OPEN).
4. Disconnect battery charger AC input T1/Neutral
cable (white sleeve) at controller.
5. Remove the 7.5 A fuse from the generator's control
panel.
6. Disconnect the battery cables. Remove the
negative cable first.
WARNING
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.
7. Drain the oil completely while the engine is still
warm, and then refill the crankcase with oil. See
Changing the Oil and Oil
8. Attach a tag to the engine indicating the viscosity
and classification of the new oil in the crankcase.
9. Remove the spark plug(s) and spray a fogging
agent into the spark plug(s) threaded openings.
Install and tighten the spark plug(s) to specification.
10. Remove the battery and store it in a cool, dry
place.
11. Clean and wipe down the entire generator
enclosure.
