Ensure that all of the safety messages are legible. Clean the safety messages or replace the safety messages if the words cannot be read or if the illustrations are not visible. Use a cloth, water, and soap to clean the safety messages. Do not use solvents, gasoline, or other harsh chemicals. Solvents, gasoline, or harsh chemicals could loosen the adhesive that secures the safety messages. The safety messages that are loosened could drop off of the engine.
Replace any safety message that is damaged or missing. If a safety message is attached to a part of the engine that is replaced, install a new safety message on the replacement part. Your Caterpillar dealer can provide new safety messages.

| |
| Illustration 12 | g00296943 |
|
|
Improper lift rigging can allow unit to tumble causing injury and damage. |
If improper equipment is used to lift the engine, injury and damage can occur. Use cables that are properly rated for the weight. Use a spreader bar and attach the cables according to the information on the safety message.
| |
| Illustration 13 | g00295926 |
The safety message for the barring device is located on the guard of the barring device.
| |
| Illustration 14 | g00296978 |
|
|
Guards must be in place prior to operating barring device motor. Remove all hand tools prior to operating barring device motor. |
The guard covers gears that rotate. Hands can be trapped in rotating gears. This can cause personal injury. Tools can be trapped in rotating gears. This can cause property damage. Ensure that no tools are in the barring device and ensure that the guard is secure before the barring device is operated.
| |
| Illustration 15 | g00123178 |
The safety message for coolant is located on the expansion tank or on the heat exchanger. The safety message for coolant is also located on the covers of the outlets for the cooling system.
| |
| Illustration 16 | g00123182 |
|
|
Drain coolant before removing covers. |
When the engine is at operating temperature, the engine coolant is hot. The engine coolant is also under pressure. The radiator and/or the heat exchanger contain hot coolant. All lines to the heaters or to the engine contain hot coolant. Contact can cause severe burns.
| |
| Illustration 17 | g00123184 |
The safety message for the crankcase covers is located on the crankcase covers.
| |
| Illustration 18 | g00123185 |
|
|
Flash fire may result in personal injury, if crankcase covers are removed within fifteen minutes after emergency shut down. Do not restart engine until cause for shutdown has been corrected. |
Electrical Distribution (Generator)
| |
| Illustration 19 | g00296979 |
The safety message for electrical distribution (generator) is located on the covers of the generator.
| |
| Illustration 20 | g00296980 |
|
|
Do not connect generator to a utility electrical distribution system unless it is isolated from the system. Electrical feedback into the distribution system can occur and could cause personal injury or death. Open and secure main distribution system switch, or if the connection is permanent, install a double throw transfer switch to prevent electrical feedback. Some generators are specifically approved by a utility to run in parallel with the distribution system and isolation may not be required. Always check with your utility as to the applicable circumstances. |
CSA Hazardous Atmosphere (Junction Box)
| |
| Illustration 21 | g00297179 |
A safety message for the Canadian Standards Association (CSA) hazardous atmosphere is located on the junction box.
| |
| Illustration 22 | g00297180 |
|
|
Do not disconnect equipment unless power has been disconnected or the area is known to be non-hazardous |
Approval by the CSA is a requirement for engines that operate in hazardous locations. Volatile flammable gases are present in these locations. The gases are normally confined within closed systems. The gases can only escape if the system accidentally breaks down. The CSA warning is intended to prevent a hazardous atmosphere from igniting.
Volatile flammable gas that is contacted by a spark will cause an explosion. This could result in personal injury or death. Also, property could be damaged.
Do not disconnect electrical equipment unless the power has been disconnected. Otherwise, ensure that the atmosphere is not hazardous. Electrical equipment includes the following components: ignition system, engine control system, wiring harnesses and sensors.
CSA Hazardous Atmosphere (Control Panel)

|
(1) safety message on transformer
(2) Flange (3) Tube | |
The safety messages for the Canadian Standards Association (CSA) installation of transformers are located on the transformers.
| |
| Illustration 26 | g00297178 |
|
|
Coil must be mounted without flange gasket. |
Approval by the CSA is a requirement for engines that operate in hazardous locations. Volatile flammable gases are present in these locations. The gases are normally confined within closed systems. The gases can only escape if the system accidentally breaks down. The CSA warning is intended to prevent a hazardous atmosphere from igniting.
Volatile flammable gas that is ignited will cause an explosion. This could result in personal injury or death. Also, property could be damaged.
If a fire should occur within tube (3), the flame could possibly burn through a gasket. This would create a gap under flange (2). The gap would enable the flame to ignite a hazardous atmosphere.
To meet the approval of the CSA, the transformer (coil) must be installed without a gasket under flange (2). This provides a connection that limits the potential for an explosion.
