VALVE-EXHAUST 3287496 - Caterpillar

High Idle Start-Up Restriction (Later)
Applicable to excavators equipped with later power mode and work mode controls that retain initial settings from previous operation at start-up.To prevent accidental higher idle speeds (throttle positions 6 thru 10) at start-up, the engine will be regulated to 1300 rpm by the AEC. For throttle positions 1 thru 5, the engine speed will be regulated by the governor. This feature protects vital engine parts from damage that may occur when the rpm is too high for a cold or inadequately lubricated engine at start-up.Starting Above 0°C (32°F)
Key must be in run position with engine running to maintain electrical and hydraulic functions and prevent serious machine damage.If the engine does not start, return the key to OFF before returning it to START.Do not crank the engine for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking again.
1. Insert the key into the disconnect switch and turn the switch to the ON position. 2. Make sure the circuit breaker reset button remains depressed. 3. This machine is equipped with an engine neutral start system. The system allows engine starting only when the hydraulic activation control lever is in the LOCKED position. Move the hydraulic activation control lever to the LOCKED position.4. Move the implement control levers to the HOLD position. 5. Turn engine start switch (1) to the ON position. 6. All of indicators on the monitor panel should be activated for approximately 2.5 seconds and the action alarm should sound for one second. If any of the indicators are not activated or the action alarm does not sound, have the electrical system checked and all necessary repairs made before starting the engine.7. Turn engine speed dial (2) to position "1".8. Turn engine start switch (1) to the START position.9. Release the engine start switch key after the engine starts.Starting Below 0°C (32°F) (If Equipped with Ether Starting Aid)
Inject starting aid (ether), only while cranking the engine.Use sparingly, excessive ether without cranking can cause piston and ring damage.Wait approximately two seconds before injecting again.Use ether for cold starting purposes only.After every 30 seconds of engine cranking, allow two minutes for starting motor to cool before cranking again.
1. Repeat steps 1 through 8 in Starting Above 0°C (32°F). 2. Push the front of starting aid (ether) switch and release.3. Operate the start aid switch every two seconds while cranking the engine. Continue use until the engine starts and is running smoothly.4. Release the engine start switch key when engine starts. Ether start cylinder or bottle container is located in the radiator compartment. See Ether Starting Aid Cylinder in the When Required section for container information.For starting below -18°C (0°F), use of optional cold weather starting aids is recommended. A coolant heater, fuel heater, jacket water heater or extra battery capacity may be required.At temperature below -23°C (-10°F), consult your Caterpillar dealer, or refer to the Operation & Maintenance Manual for Cold Weather Operation Recommendations SEBU5898, available from your Caterpillar dealer.Starting
