Personal injury or death may result from failure to adhere to the following procedures. Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. Clean up all leaked or spilled fuel. Do not smoke while working on the fuel system. Turn the disconnect switch OFF or disconnect the battery when changing fuel filters. |
Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand. Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns. Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes. |
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool. |
- Drain the coolant. Refer to Operation and Maintenance Manual, "Cooling System Coolant (ELC) - Change" for the correct draining and filling procedure.
