Service Specifications

Every 10 hours of operation........................................Check radiator coolant level Every 250 hours of operation....................Check and tighten coolant hose clamps Every 2000 hours or once each year.................................Change system coolant Coolant capacity.................................7.0 U.S. quarts (1.5 U.K. gallons, 6.6 litres) Thermostat...........................................................181°F to 203°F (83°C to 95°C) Radiator cap.................................................................15 PSI (103 kPa, 1.02 Bar) Fluid type........................................................50% water and 50% ethylene glycol

Coolant Solution

A mixture of 50% ethylene glycol and 50% water must be used in this machine. This mixture is used if the lowest ambient temperature is above -34°F (-37°C). If the temperature is lower, adjust the mixture to 60% ethylene glycol, 40% water. It is recommended that ethylene glycol and water be used in your machine all year. NOTE: NOTE: After you fill the cooling system, mix the ethylene glycol and water completely by running the engine at operating temperature for approximately five minutes. This procedure must be done when the machine is in temperatures below 32°F (0°C).

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

1.RADIATOR CAP Check the radiator coolant level when the coolant is cold and the engine is stopped. Open the rear door and remove the radiator cap. The coolant level must be up to the radiator cap opening. IMPORTANT: Only add the correct mixture of ethylene glycol and water to the radiator.

Cleaning Cooling System

Drain, flush, and refill the engine coolant every 2000 hours of operation or each year, whichever occurs first. Clean the system and replace the coolant if the coolant becomes dirty or has the color of rust.

DO NOT remove the radiator cap if the coolant is hot.

3.Add cleaning solution to the cooling system and fill the cooling system with clean water. Follow the directions included with the cleaning solution. 4.After you drain the cleaning solution, flush with clean water. 5.Check the hoses, elbows and water pump for leaks. 6.Make sure that the outside of the engine and radiator is clean. 7.Fill the cooling system until the coolant level is up to the top of the radiator cap opening. 8.Fill the coolant reservoir up to the

FULL mark on the reservoir. 9.Start the engine and increase the temperature of the engine coolant.

When the coolant is at operating temperature, stop the engine and allow to cool. Check the coolant level at the coolant reservoir only.

Do not remove the radiator cap. 10.Dispose of drained coolant responsibly. Do not pour on ground or down drain.
