Hints for Cold Weather Operation
If the engine has started, run the engine until the coolant temperature gauge is within operating temperature range. Achieving operating temperature will help prevent the intake valves and exhaust valves from sticking.
Warm up the oil for each system. Warming the oil will help prevent damage to system components in each system. This also helps improve machine performance and response time.
The cooling system and the lubrication system for the engine do not lose heat immediately upon shutdown. This means that an engine can be shut down for a few hours and the engine can still have the ability to start readily. If the engine is shut down for at least eight hours, the engine should be considered cooled to outside temperature.
Install the correct lubricant in each compartment before the beginning of cold weather.
Check all rubber parts (hoses, fan drive belts, etc) weekly.
Check all electrical wiring and connections for any fraying or damaged insulation.
Keep all batteries fully charged and warm.
Fill the fuel tank at the end of each shift.
Check the air cleaners and the air intake daily. Check the air intake more often when you operate in snow.
Personal injury or property damage can result from alcohol or starting fluids.Alcohol or starting fluids are highly flammable and toxic and if improperly stored could result in injury or property damage.
The optional automatic ether injection system is the only starting fluid system that is recommended. Excessive starting fluid can cause piston and ring damage. Use starting fluid for cold starting purposes only.
For starting with ether in cold weather, refer to Operation and Maintenance Manual, "Starting Below 0° C (32°F) with Ether Starting Aid" for further information.
For jump starting with cables in cold weather, refer to the Operation and Maintenance Manual, "Starting with Jump Start Cables" for further instructions.
For jump starting with auxiliary starting receptacles in cold weather, refer to the Operation and Maintenance Manual, "Starting with Auxiliary Start Receptacles" for further instructions.
Several products for enhanced performance in cold weather are available. Consult your Caterpillar dealer for further information.Hints for Warm-Up
After the engine has started, perform the following tasks:
Run the engine without a load. Run the engine until the coolant temperature gauge is within operating range.
Extend the ejector blade and retract the ejector blade several times in order to warm the oil for the ejector system.
Turn the machine from the left to the right in order to warm the oil for the steering system.
Drive the machine without a load. Drive the machine for a sufficient time period in order to warm the final drive oil and the differential oil. Do not exceed a speed of 16 km/h (10 mph). Perform this task for a time period of approximately fifteen minutes to thirty minutes.Refer to Operation and Maintenance Manual, SEBU5898, "Cold Weather Recommendations for Caterpillar Machines" for further information.
