Exterior; Alternator - Kohler APM402 Operation

3.11.4.1 Internal Engine Components
If you have access to a fogging agent or SAE 10 oil prepare the pistons and cylinders for storage as follows:
1. While the engine is running, spray a fogging agent or SAE 10 engine oil into the air intake for about two minutes until
the engine stops.
2. Place the generator set master switch in the OFF/RESET position.
If a fogging agent is not available perform the following:
1. Remove the spark plugs.
2. Pour 15 cc (0.5 oz.) of engine oil into each spark plug hole.
Ignition System Damage. Refer to the engine operation manual for ignition system precautions before cranking the engine
while the spark plug wires are disconnected.
3. Toggle the generator set master switch to crank the engine two or three revolutions to lubricate the cylinders.
4. Reinstall the spark plugs and torque them to specifications.

3.11.5 Exterior

1. Clean the exterior surface of the generator set.
2. Seal all engine openings except for the air intake with non absorbent adhesive tape.
3. To prevent impurities from entering the air intake and to allow moisture to escape from the engine, secure a cloth over
the air intake.
4. Mask electrical connections.
5. Spread a light film of oil over unpainted metallic surfaces to inhibit rust and corrosion.

3.11.6 Alternator

WARNING
Combustible materials. A fire can cause severe injury or death. If using generator heaters during storage, remove
combustible materials such as covers from contact with the heater or from areas where heat could potentially cause a fire.
Humidity, moisture, and dust can damage the alternator during storage. Store the generator set in a clean, dry area and protect
the alternator from inclement weather. Keep room temperatures relatively constant to prevent condensation on the windings.
Cover ventilation and other entry points to prevent damage by rodents, birds, and insects.
Before returning the alternator to service, have an authorized service distributor/dealer, perform the following alternator service:

Clean the ventilation circuit.

Blow dust off the windings.

Check the rotor and stator winding insulation.

Check the rotor and stator winding resistance and continuity.

On units with regreasable bearings, grease the bearings and rotate the shaft to distribute grease on the bearings.
110
Risk of fire.
Can cause severe injury or death.
Do not smoke or permit flames or sparks near fuels or the fuel system.
