Diesel engine exhaust contains products of combustion which may cause personal injury. Always start and operate the engine in a well ventilated area, and, if in an enclosed area, vent the exhaust to the outside. |
|
|
Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts. Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified. The machine must be parked on a level surface and the engine stopped. Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine. |
|
|
Personal injury or death can result from sudden machine movement. Sudden movement of the machine can cause injury to persons on or near the machine. To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine. |
|
|
Injury to personnel can result if they are not in the operator's view. Allow only essential personnel near the machine, and make sure the personnel are in the operator's view when testing, to prevent injury. Make sure checks are done in an open area. |
|
|
To prevent injury or death, never work under a machine while a test is being performed. |
|
|
Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of all fluids according to local regulations and mandates. |

To prevent damage to the eccentric weight shaft bearings, do not operate the vibratory system for more than 5 minutes without rotating the drums. Do not operate the vibratory system when the machine is on a hard surface, such as concrete. |
Note: Park the machine on soft dirt or place tires under the drums. Alternately, the machine can be lifted onto jacks, or the machine drums may be supported by air bags. The weight of the machine is approximately
- Drive the machine to a smooth, horizontal surface.
