Never add coolant to an overheated engine. Allow the engine to cool first.
Measure the specific gravity of antifreeze solution frequently in cold weather to ensure adequate protection.
When permanent type antifreeze and water solutions are used in the cooling system, drain and replace the
solution EVERY 2000 SERVICE HOURS OR YEARLY.
If the machine is shipped to, or stored in an area with freezing temperatures, the cooling system must either be
protected to the lowest expected temperature or drained completely.
The engine cooling system is protected to -20°F (-30°C), with permanent type antifreeze, when shipped from the factory.
Pure undiluted antifreeze will freeze at -10°F (-23°C).
Use clean water that is low in scale forming minerals--not softened water.
When refilling the cooling system, always check the coolant level when the engine reaches normal operating temperature.
Filling the cooling system at over a 5 gpm (19 liters/min) rate can cause air pockets in the cooling system.
When measuring the coolant level inspect the filler cap gasket. Replace the gasket if it is damaged.
Premix antifreeze to provide protection to the lowest expected temperature.
Operate with a thermostat in the cooling system all year round. Cooling system problems can arise without a thermostat.
Engine Air Cleaner
Inspect the air cleaner precleaner daily for accumulation of dirt and debris.
Service the air cleaner when the red band is visible in the air cleaner indicator.
