EXPLANATION OF SCHEDULED MAINTENANCE
Check the structual integrity of the water injected exhaust elbow casting. Check the integrity
of the exhaust system attached to the elbow. All hose connections should be secure. No
chaffing. No exhaust leaks. Hoses and muffler are in good serviceable condition.
