5 - OPERATING INSTRUCTIONS
84
COLD TEMPERATURE OPERATION
IMPORTANT: During cold ambient temperatures
never run the engine at low idle speed for long
periods of time. Never run the engine for long periods
of time when the coolant temperature is below
normal.
To start and operate your Combine during cold
ambient temperatures:
1. BATTERIES - Must have a full charge.
2. FUEL - Must be clean and with no water. See
Fuel Specifications in this manual.
3. ENGINE OIL - Must have the correct viscosity for
the ambient temperature range.
4. TRANSMISSION HYDRAULIC FLUID - Use
Case IH HY-TRANĀ® ULTRA.
5. COOLING SYSTEM - Must have a minimum of
50 percent Ethylene Glycol solution for
protection.
6. STOPPING THE ENGINE - Permit the engine
temperature to decrease before stopping.
7. CONDENSATION IN FUEL TANK - To prevent
condensation in the fuel tank and water entering
the fuel system, fill the fuel tank after each
operating day.
8. FUEL FILTER WATER TRAP - During cold
ambient temperatures, make sure to remove
water from the water trap each day or damage
will occur.
During cold ambient temperatures, the engine will not heat to or keep the rated operating temperature at slow
engine speeds. Slow engine speeds in cold temperatures can cause damage to the engine. Use the following
procedures to warm the engine and hydraulic fluid and to keep the correct operating temperatures.
1. WARMING THE ENGINE AND HYDRAULIC
FLUID
A. Start the engine using the procedure shown
in this manual.
B. Warm the hydraulic fluid to operating
temperature, run the engine at intermediate
speed range for approximately five (5)
minutes.
IMPORTANT: Operating the Combine with cold
hydraulic fluid can cause rough operation with
possible injury to the operator.
2. KEEP ENGINE AT CORRECT OPERATING
TEMPERATURE - When the engine is operating
in cold ambient temperatures without a load,
keep the engine warm by running the engine at
intermediate speed range.
3. STOPPING THE ENGINE - Run the engine at
slow speed for 3 to 5 minutes. This will permit the
engine temperature to decrease gradually before
stopping the engine.
WARNING: DO NOT use ether starting fluid. Serious engine damage and death or serious personal injury
may occur.
