WARNING: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

NOTICE: Mixing ELC with other products will reduce the effectiveness of the coolant. This could result in damage to cooling system components.

Note: The machine was shipped from the factory with Extended Life Coolant (ELC) in the cooling system.

Drain the coolant whenever the coolant is dirty or whenever the coolant is foaming.

Machine cooled down before coolant change?
