2. Lower the bucket to the ground.
3. Turn the auto-idle switch off.
IMPORTANT: The turbocharger may be damaged if the
engine is not properly shut down.
4. Run the engine at slow idle speed without load for five
minutes.
5. Stop the engine. Remove the key from the key switch.
6. Pull the pilot control shut-off lever to the LOCK position.
