Note: If your machine is equipped with the Machine Security System, refer to the "Machine Security System (If Equipped)" section below for more information.
Note: The engine will not start unless the direction control switch is in NEUTRAL.
Note: When the ignition switch is turned ON, the instrument cluster will perform a “self test”. Wait until completion before you start the engine.
Note: In applications for cold weather, pause until the indicator lamp for the starting aid turns off. The engine start switch in the ON position activates the glow plugs. Once the indicator light for the starting aid goes off, start the engine.
Note: If the machine is equipped with the Machine Security System, turn the engine start switch key to the ON position. Hold for 3 seconds before starting the machine.

Do not crank the engine for more than 10 seconds. Allow the starter motor to cool for 30 seconds before cranking again. Do not engage the starter when the flywheel is turning. |
 |
|
Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury. |

Keep the engine speed low until the engine oil fault alarm shuts off and the indicator light shuts off. Wait for ten seconds. If the indicator light stays on, stop the engine. Investigate the cause of the problem before you start the engine again. |
Warm up the engine at low idle for 5 minutes. Cycle the hydraulic cylinders in order to circulate the oil. Repeat this procedure until the hydraulic system is warm enough to operate the attachments.
Monitor the gauges while operating the machine controls.
The parking brake indicator will remain on until releasing the parking brake.
While the engine idles in order to warm up, the operator observes the following recommendations:
- If the temperature is greater than
0° C (32° F) , warm-up the engine for approximately 15 minutes. - If the temperature is less than
0° C (32° F) , warm-up the engine for approximately 30 minutes. - If the temperature is less that
−18° C (0° F) or hydraulic functions are sluggish, additional time may be required.
Machine Security System (If Equipped)

|
If equipped with a Caterpillar Machine Security System (MSS), this machine may not start under certain conditions. Read the following information and know your machine's settings. Your Caterpillar dealer can identify your machine settings. |
|
Machine Security System (MSS) - Machines that are equipped with a Caterpillar Machine Security System (MSS) can be identified by a decal in the operator station. MSS is designed to prevent theft of the machine or unauthorized operation. |
MSS may be programmed to read a standard Caterpillar key or an electronic key. The electronic key contains an electronic chip within the plastic housing of the key. Each key emits a unique signal to the MSS. The keys can be identified by a gray housing or a yellow housing. MSS can have programmed settings to require an electronic key or a standard Caterpillar key for starting during certain periods of time.
When the key start switch of the machine is turned to the ON position. The ECM will read the unique ID that is stored in the electronic key. The ECM will then compare this ID to the list of authorized keys.

The MSS LED is located on the front console this LED will illuminate either green or red. If the LED is red, the key is not authorized.
Note: MSS will not shutdown the machine after the machine has started.
Note: When the key start switch of the machine is turned to the OFF position, the indicator lights will continue to light for 30 seconds.
The MSS can allow the operator to program the system to automatically activate at different time periods with different keys. The MSS can also be programmed to reject a specific electronic key after a selected date and time. When the key is turned to the OFF position, the MSS is active. The operator has a 30 second interval in order to restart the machine with an unauthorized key. Also if the machine stalls, there is a 30 second interval for restarting the machine. This 30 second interval is counted from the time of turning the key to the OFF position.
Note: Know the machine settings because the use of an electronic key is no guarantee that the machine can be restarted.
An expiration date can be set for each electronic key that is contained in the list of keys for the machine. The key will no longer start the machine when the internal clock in the security system passes the expiration date. Each entry in the list of keys can have a different expiration date.
Spare keys are available from your dealer. Before a key can operate the machine, the MSS must be set to accept that particular key. Contact your Caterpillar dealer for information on additional features of the MSS.
