CONE 1C3970 - Caterpillar

Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking again.Turbocharger (if equipped) damage can result, if the engine rpm is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient.
Engine Starting Below 0°C (+32°F) (If Equipped with Ether Starting Aid)
Inject starting aid (ether), only while cranking the engine, or after initial start-up, until the engine is running smoothly.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.Turbocharger (if equipped) damage can result, if the engine rpm is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient.
1. Follow Steps 1 through 5 in Engine Starting Above 0°C (+32°F). Then proceed with the following steps.2. Turn the start switch key to start the engine. 3. Push the starting aid (ether) switch and release.4. Operate the start aid switch every two seconds while cranking the engine. Continue use until the engine starts and is running smoothly.5. Release the start switch key when the engine starts.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 temperatures below -23°C (-10°F), consult your Caterpillar dealer, or refer to the Operation & Maintenance Manual for Cold Weather Recommendations, SEBU5898, available from your Caterpillar dealer.Engine Starting with Jump Start Cables
Batteries give off flammable fumes that can explode resulting in personal injury.Prevent sparks near the batteries. They could cause vapors to explode. Do not allow jump start cable ends to contact each other or the machine.Do not smoke when checking battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.Always wear eye protection when starting a machine with jump start cables.Improper jumping procedures can cause an explosion resulting in personal injury.Always connect the battery positive (+) to battery positive (+) and the battery negative (-) to battery negative (-).Jump only with a battery source with the same voltage as the stalled machine.Turn off all lights and accessories on the stalled machine. Otherwise, they will operate when the jump source is connected.
When starting from another machine, make sure the machines do not touch. This could prevent damage to engine bearings and electrical circuits.Turn on (close) the disconnect switch prior to the electrical source connection to prevent damage to electrical components on the stalled machine.Severely discharged maintenance free batteries will not fully recharge from the alternator alone after jump starting. The batteries must be charged to the proper voltage with a battery charger. Many batteries thought to be unusable, are still rechargeable.This machine has a 24 volt starting system. Use only equal voltage for jump starting. Use of a higher voltage will damage the electrical system.Refer to Special Instruction, Battery Test Procedure,
