Check the coolant level every 10 hours of operation oreach day. When the
coolant is cold, the coolant must be two inches (50 mm) below the level of the
radiator opening. Add coolant if necessary. Do not add coolant above the
correct level.
Ethylene Glycol Coolant
A mixture
0
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 (-3]0 C). If the ambient temperature is lower, adjust the mixture. It is
recommended that ethylene glycol and water be used in your machine all year.
IMPORTANT: Mix the ethylene glycol and water completely by running
the engine at operating temperature for approximately five minutes. This
procedure must be done before the machine is put outside in temperatures
below 32° F (0°
C).
Cleaning the System
Clean the cooling system every 2000 hours or at least once a year. Clean
more often in areas where hard water, containing scale forming minerals is all
that is available.
1. While the coolant is still hot, open the radiator drain valve and the engine
block drain valve. See photos, following page. Remove radiator cap to aid
draining. Drain coolant thoroughly and close drain valves.
2. Add a radiator cleaner to the system and refill with clean water. Use a
cleaner marketed by a reputable manufacturer. Follow directions pro-
vided with the cleaner.
3. Check hoses, elbows, pump and water manifold for leakage.
4. Drain the cleaning solution and water. Flush the system with clean water.
5. Clean dirt off exterior of radiator. Blowout dirt between fins with com-
pressed air.
6. Refill cooling system with the recommended coolant.
