NOTICE

When starting from another machine, make sure that the machines do not touch. This could prevent damage to engine bearings and electrical circuits. Turn on (close) the battery disconnect switch prior to the boost connection to prevent damage to electrical components on the stalled machine. Severely discharged maintenance free batteries do not fully recharge from the alternator after jump starting. The batteries must be charged to 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 the same voltage for jump starting. Use of a higher voltage damages the electrical system.

Some Caterpillar machines may be equipped with auxiliary starting receptacles. All other machines can be equipped with a receptacle from parts service. A permanent receptacle is always available for jump starting.

There are two cable assemblies that can be used to jump start the stalled machine. You can jump start the stalled machine from another machine that is equipped with an auxiliary starting receptacle or with an auxiliary power pack. Your Caterpillar dealer can provide the correct cable lengths for your application.

Move the transmission control lever on the stalled machine to the NEUTRAL position. Engage the transmission neutral lock. Engage the parking brake. Lower all attachments to the ground. Move all controls to the HOLD position.
Turn the start switch key on the stalled machine to the OFF position. Turn off all accessories.
Turn ON the battery disconnect switch on the stalled machine .
Move the machine that is being used as a power source close to the stalled machine. The jump start cables should reach the batteries on both machines. DO NOT ALLOW THE MACHINES TO CONTACT EACH OTHER.
Stop the engine on the machine that is being used as a power source. If you use an auxiliary power source, turn off the charging system.
Connect the appropriate jump start cable to the auxiliary starting receptacle on the stalled machine.
Connect the other end of the jump start cable to the auxiliary starting receptacle of the machine that is being used as a power source.
Start the engine on the machine that is being used as a power source or energize the charging system on the auxiliary power source.
Allow the machine that is being used as a power source to charge the batteries for two minutes.
Attempt to start the stalled engine.
Immediately after the stalled engine starts, disconnect the jump start cable from the power source.
Disconnect the other end of the jump start cable from the stalled machine.
Conclude the failure analysis on the starting charging system of the stalled machine, as required. Check the machine while the engine is running and the charging system is in operation.
