HOSE ASSEM. 3P4825 - Caterpillar

Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury.
The ability to start the engine will be improved at temperatures below −18 °C (0 °F) from the use of a jacket water heater or extra battery capacity.When Group 2 diesel fuel is used, the following items provide a means of minimizing starting problems and fuel problems in cold weather: Engine oil pan heaters, jacket water heaters, fuel heaters and fuel line insulation.Use the procedure that follows for cold weather starting.Note: Do not adjust the engine speed control during start-up. The electronic control module (ECM) will control the engine speed during start-up.
Disengage any driven equipment. Note: During key ON, the indicator lamps will be illuminated for 2 seconds in order to check the lamp operation. If any of the indicator lamps do not illuminate check the bulb. If any indicator lamps stay illuminated or flash, refer to Troubleshooting, "Indicator Lamp Circuit - Test".
Turn the keyswitch to the RUN position. Leave the keyswitch in the RUN position until the warning light for the glow plugs is extinguished.
When the warning light for the glow plugs is extinguished, turn the keyswitch to the START position in order to engage the electric starting motor and crank the engine. Note: The operating period of the warning light for the glow plugs will change due to the ambient air temperature.
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
Allow the keyswitch to return to the RUN position after the engine starts.
Repeat step 2 through step 4 if the engine fails to start. Note: The engine should not be “raced” in order to speed up the warm-up process.
Allow the engine to idle for 3 to 5 minutes, or allow the engine to idle until the water temperature indicator begins to rise. When idling after the engine has started in cold weather, increase the engine rpm from 1000 to 1200 rpm. This operation 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. Allow the white smoke to disperse before proceeding with normal operation.
Operate the engine at low load until all systems reach operating temperature. Check the gauges during the warm-up period.
