Daily before starting the engine, check the coolant level the coolant reserve bottle. The coolant level should be between the "FULL" and "LOW" lines when the engine is cool.

Pressure Cooling System

Check and service cooling system according to maintenance instructions. Hot coolant can spray out if radiator cap is removing while system is hot. To remove radiator cap, let system cool, turn to first notch, and then wait until all pressure is released. Scalding can result from fast removal of radiator cap.

1.The pressure cap on a pressure cooling system has a control valve

that operates as a SAFETY RELIEF VALVE to keep the pressure within the system operating range.

Operating the engine without a pressure cap or with a pressure cap that has a control valve that is not set to operate at the correct pressure can cause damage.

2.A pressure cooling system decreases the loss of coolant caused by evaporation or boiling. The system must have good seals at the radiator cap, hoses and hose connections. It is important that you stop ALL LEAKS OF ANY SIZE as soon as the leaks are found. A small leak can become a large flow when pressure is increased in the cooling system. While the tractor is in operation, a weak hose can break and cause injury or damage. Check all hoses and hose connections with frequency. KEEP HOSES, HOSE CONNECTIONS AND PRESSURE CAP IN GOOD CONDITION.
