Refer to the 3408 and 3412 Industrial Engine Troubleshooting Manual for more information.Below 12°C (55°F)
Caterpillar engines are designed to start at temperatures above 12°C (55°F) without using starting aids. If the temperature is below 12°C (55°F), a cylinder block coolant heater may be needed or crankcase oil may need to be heated.At temperatures below 0°C (32°F), it may be necessary to spray starting fluid into the air cleaner inlet. Additional injections of ether may be required to start and/or achieve low idle speed.
When using starting fluid, follow the manufacturer's instructions carefully, use it sparingly and spray it only while cranking the engine. Failure to do so, could result in an explosion and/or fire and possible personal injury.
Excessive ether can cause piston and ring damage. Use ether for cold starting purposes only. Do not use excessive starting fluid during starting or after the engine is running.
* Depress ether aid switch (if equipped with ether injection) and hold for three seconds, then release before performing step 3 above.* Begin cranking engine and depress ether switch and hold for three seconds then release. Additional injections of ether may be required to start and/or achieve low idle speed.The engine will run at low idle and will run smoothly as the electronic control system gradually increases the fuel flow to high idle in the Cold Mode procedure. Low Idle rpm - 600 - 750, Cold Mode rpm - 900 - 1000.Allow white smoke to clear up and proceed with normal operation.For starting below -18°C (0°F), use of optional cold weather starting aids are recommended. A jacket water heater or fuel heater may be required. Consult your Caterpillar dealer for additional information.Starting From External Electrical Source
Make initial determination as to failure of engine to crank. Refer to special instruction SEHS7768 on use of 6V2150 Starting/Charging Analyzer Group.If the installation is not equipped with a back-up battery system, then it may be necessary to start the engine from an external electrical source.Many batteries thought to be unusable, are still rechargeable. Severely discharged maintenance free batteries might not fully recharge from the alternator alone after jump starting. The batteries must be charged to the proper voltage with a battery charger. Refer to Special Instruction, SEHS7633, Battery Test Procedure, available from your Caterpillar dealer, for complete testing and charging information.
Be sure the main power switch is in the OFF position before attaching the booster cables to the engine being started. Turn OFF all electrical accessories.When boost starting an engine, follow the instructions to properly start the engine. This engine is equipped with a 24 volt starting system. Use only equal voltage for boost starting. The use of a welder or higher voltage will damage the electrical system and is not recommended.Do not allow the free ends of jumper cables to touch the engine. This helps avoid sparks. Do not reverse the battery cables. The alternator can be damaged. Attach ground cable last and remove first.
1. When using booster cables, be sure to connect in parallel: Connect
