Starting

WARNING

Explosion.

Gasoline vapors can cause explosion and severe injury or death.

Before starting generator set, operate blower 4 minutes and check engine compartment for gasoline vapors.

NOTE

For reliable starting, allow at least 30 seconds after shutdown before restarting a hot engine.

Ensure that the manual fuel shutoff valve (if equipped) is open. Then rock the master Start/Stop Switch on controller (or use Start/Stop Switch on remote panel) to the Start position for a maximum of 7 seconds or until the engine starts.

NOTE

Do not crank the engine continuously for more than 7 seconds at a time. Allow a 5-second period between starting attempts if the engine does not start. If the engine fails to start after three attempts, contact an authorized Kohler dealer/distributor for repair. Failure to follow these guidelines may result in burn-out of the starter motor from overheating.

If the engine fails to start after the first attempt, close the seacock before a second start-up attempt. This action will help prevent seawater from entering the engine cylinders through the exhaust valve. Once the engine starts, the seacock must be re-opened to allow passage of cooling water.

NOTE

Failure to open the seacock after the generator set is running will result in serious engine damage due to overheating.

NOTE

Ensure that the marine ship-to-shore transfer switch, if used, is in proper position.

Stopping

Disconnect the load from the generator set and allow the generator set to run at no-load for 5 minutes to cool down the engine. Then rock the master Start/Stop switch on the controller (or the Start/Stop Switch on a remote panel) to the Stop position and hold it in the Stop position until the generator set comes to a complete stop.

NOTE

Allow unit to come to a complete stop before attempting to start the generator set again.
