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.
Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury.
For jump starting with cables in cold weather, refer to the Operation and Maintenance Manual, "Starting with Jump Start Cables." for instructions.Viscosity of the Engine Lubrication Oil
Correct engine oil viscosity is essential. Oil viscosity affects lubrication properties and wear protection that the oil provides for the engine. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended viscosity of oil.Recommendations for the Coolant
Provide cooling system protection for the lowest expected outside temperature. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for the recommended coolant mixture.In cold weather, check the coolant often for the correct glycol concentration in order to ensure adequate freeze protection.Engine Block Heaters
Engine block heaters (if equipped) heat the engine jacket water that surrounds the combustion chambers. This equipment provides the following functions:
Startability is improved.
Warm up time is reduced.An electric block heater can be activated once the engine is stopped. A block heater can be 110 V or 240 V. The output can be 750/1000 W. Consult your Cat dealer for more information.Idling the Engine
After starting the engine, the engine speed will be governed for a maximum period of 25 seconds. When idling after the engine is started in cold weather, increase the engine rpm from 1000 to 1200 rpm. This idling will warm up the engine more quickly. Maintaining an elevated low idle speed for extended periods will be easier with the installation of a hand throttle. The engine should not be “raced” in order to speed up the warm-up process.While the engine is idling, the application of a light load (parasitic load) will assist in achieving the minimum operating temperature. The minimum operating temperature is 80° C (176° F).Constant speed engines should be allowed to operate at low idle for 3 minutes before used at operational speed. If the low idle option is not available, then operate the engine at operational speed with no load for 2 minutes.Recommendations for Coolant Warm Up
Warm up an engine that has cooled below normal operating temperatures due to inactivity. This warn-up should be performed before the engine is returned to full operation. During operation in very cold temperature conditions, damage to engine valve mechanisms can result from engine operation for short intervals. This damage can happen if the engine is started and the engine is stopped many
