Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly.
Improper operation, lubrication, maintenance, or repair of this product can be dangerous and could result in injury or death.
Do not operate or perform any lubrication, maintenance, or repair on this product until you have read and understood the Tool Operating Manual.
Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons.
The hazards are identified by the "Safety Alert Symbol" and followed by a "Signal Word" such as "DANGER","WARNING", or "CAUTION". The Safety Alert "WARNING" label is shown below.
A non-exhaustive list of operations that may cause product damage are identified by "NOTICE" labels on the product and in this publication.
Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this publication and on the product are, therefore, not all inclusive. If a tool, procedure, work method, or operating technique that is not recommended by Caterpillar is used, the operator must be sure that the procedures are safe. The operator must also be sure that the product will not be damaged or made unsafe by any unspecified procedures.
The information, specifications, and illustrations in this publication are based on information that was available at the time that the publication was written. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete and most current information before you start any job.
When replacement parts are required for this product Caterpillar recommends using Caterpillar replacement parts or parts with equivalent specifications including, but not limited to, physical dimensions, type, strength, and material.

Safety Warnings
 |
Dry nitrogen is the only gas approved for use in the accumulator. Charging the accumulator with oxygen gas will cause an explosion. This danger will not happen if nitrogen cylinders with standard CGA (Compressed Gas Association, Inc.) Number 580 connections are used. When you order nitrogen gas, be sure that the cylinders are equipped with CGA No. 580 Connections. Do not use color codes or other methods of identification to tell the difference between nitrogen and oxygen cylinders. |
 |
|
At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure. |

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. 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 Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |
| NOTICE |
|---|
To prevent dirt and contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. This action also lessens the chance of oil spills. |

| NOTICE |
|---|
The 175-5507 Nitrogen Charging Group is not recommended for tire inflation because of the associated higher pressures and increased flow restrictions. |
Note: The 361-3889 Nitrogen Charging Group is the same as 175-5507 Nitrogen Charging Group without the 8T-0849 Pressure Gauge (0 TO 2,000-KPA (0 TO 290-PSI)) and 162-4146 Regulator . The 361-3889 is intended for use in Australia. Purchase Gauges and Regulator that are certified for use in Australia.
To charge a single cylinder, assemble the 175-5507 Nitrogen Charging Group as shown in Illustration 1. The maximum operating pressure for these parts is 20666 kPa (3000 psi).
