WARNING

MODIFICATION HAZARD

Unauthorized modifications, alterations or installations of or to this equipment are prohibited and are in violation of AR 750-10. Any such unauthorized modifications, alterations or installations could result in death, injury or damage to the equipment.

HIGH PRESSURE HYDRAULIC SYSTEM HAZARDS

Hydraulic systems can cause serious injuries if high pressure lines or equipment fail.

Never work on hydraulic systems or equipment unless there is another person nearby who is familiar with the operation and hazards of the equipment, and who can give first aid. A second person should stand by controls to turn off hydraulic pumps in an emergency.

MOVING MACHINERY HAZARDS

Be very careful when operating or working near moving machinery.

Running engines, rotating shafts, and other moving machinery parts could cause personal injury or death.

ELECTRICAL HAZARDS

Do not be misled by the term 'low voltage." Potentials as low as 50 volts may cause death under adverse conditions. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce the hazard of current flowing through the body.

High pressure exists inside lamps of searchlights and certain floodlights, especially when hot, and under certain conditions could explode causing injury from flying glass and metal particles.

When performing maintenance on the RT-1600/U Receiver/Transmitter and the HF Communication Antennas, safety harness must be worn.

FLAMMABLE LIQUID AND COMBUSTIBLE VAPOR HAZARDS

Gasoline, fuel oil, lubricating oil, grease, paint, paint thinner, cleaning solvents and other combustible liquids present a serious fire hazard. Always store combustible liquids in approved containers and in their designated compartments or deck storage locations. Ensure exhaust and ventilation fans are operating while using cleaning solvents or paint products. Never store or charge batteries in a confined space without ventilation or near operating electrical equipment.

When refueling and defueling the vessel, ensure appropriate signs are posted in visible locations and warnings are announced over the vessel's public address system. Smoking, welding and any operation which involves open flames must be prohibited throughout the vessel.

CAUSTIC AND CORROSIVE CHEMICAL HAZARDS

Battery acid and water purification chemicals such as bromine and chlorine can cause serious burns to eyes or exposed areas of skin. Always wear eye protection and protective clothing when working with caustic and corrosive chemicals. If chemicals accidentally contact skin or eyes, immediately flush with large quantities of water and seek medical attention.

COMPRESSED AIR HAZARDS

High pressure compressed air tanks, piping systems and air operated devices possess potential for serious injury to eyes and exposed areas of skin due to escaping air pressure.

ELECTROMAGNETIC RADIATION HAZARDS

Electromagnetic radiation from the searchlight, radar, and radio antennas has the potential for serious radiation burns. Do not stand in the path of radiation emission.

Change 2 a

FIRE SUPPRESSANT HAZARDS

Fire suppressant chemicals displace oxygen and can cause suffocation. Immediately evacuate areas where they will be used.

For Artificial Respiration, refer to FM 21-11.

HOW TO USE THIS MANUAL

GENERAL. This manual contains description, technical principles of operation, and operating instructions for the Landing Craft, Utility (LCU). The manual is divided into three chapters:

CHAPTER 1, INTRODUCTION, provides general information about the vessel, identifies the major components and systems by deck and compartment, and describes how the components or systems work.

CHAPTER 2, OPERATING INSTRUCTIONS, ide ntifies operating controls and indicators and explains how to use them. Most of the information is organized by the compartment in which it is located. This chapter covers preventive maintenance checks and services (PMCS), how to operate the vessel and its equipment during usual and unusual conditions, and how to respond to certain emergency conditions.

CHAPTER 3, MAINTENANCE INSTRUCTIONS, references the user to the applicable Department of the Army Technical Manual that explains what to do when something goes wrong with the vessel.

WARNINGS, CAUTIONS, AND NOTES. Information is provided throughout the manual which does not fit into a procedural step. This information is in the form of WARNINGS, CAUTIONS, and NOTES. WARNINGS are provided where injury may occur to personnel on or near the equipment. WARNING headings are boxed, as shown below:

WARNING

RADIO FREQUENCY HAZARD

• Electromagnetic radiation has the potential for serious injury or death.

• Avoid placing your body in the path of radiation emissions.

There are also a number of general WARNINGS listed in the Warning Page which should be read before operating the vessel.

CAUTIONS are provided where equipment may be damaged but no personal injuries should result. The word CAUTION is underlined, as shown below:

CAUTION

Do not hold in START position any longer than necessary to start equipment or the starter will overheat.

NOTES highlight or amplify information to operate the vessel or equipment, but no equipment damage or personnel injury is involved, as shown below:

iii

HOW TO USE THIS MANUAL - continued

NOTE

Engine should start within 10 seconds.

WARNINGS, CAUTIONS, AND NOTES SHOULD NEVER BE IGNORED.

INTERNAL REFERENCING. In this manual, internal referencing is done by paragraph number. For example:

Align fuel oil transfer piping system (see para. 2-9.a.).

The note (see para. 2-9.a.) refers you to Chapter 2, paragraph 9.a., of this manual. If the paragraph is less than 10 lines or 200 words, the information will be repeated and not referred to.

For quick reference to a vessel item or procedure, use the alphabetical index in the back of this manual.

Operating procedures that involve valves will contain the valve number, followed by the valve name, followed by the illustration callout number in parenthesis.

EXTERNAL REFERENCING. Referencing outside this manual will be by the military publication number. For example: Clean and lubricate (see LO 55-1905-223-12). The note (see LO 55-1905-223-12) refers you to the lubrication order for the Landing Craft, Utility (LCU) vessel.

PROBLEMS AND MALFUNCTIONS. The vessel may not work properly during operation. When malfunctions occur, the operator should go to the appropriate page of the equipment technical manual (TM 55-1905-223-24-series) and look for the problem in the symptom (malfunction) index of the troubleshooting section. This index will direct the operator to identify exactly what is wrong and correct it. The procedure may direct the operator to other sections of the manual, such as Maintenance. When the operator has done all that can be done and the problem still exists, the operator will be directed to notify higher maintenance. If there is no procedure provided in the symptom (malfunction) index to correct the problem, then the operator should notify higher maintenance.

APPENDIXES. There are six appendixes that provide additional information needed to operate the vessel.

Various lists of equipment and supplies, sounding tables, and other general information are provided. The appendixes are lettered A through F.

SECTION INDEXES. Section indexes are provided for each section in chapter 2 to assist you in locating the desired information.

ALPHABETICAL INDEX. Items and operations are listed in alphabetical order by paragraph number.

LOCATION TERMS. The terms starboard (STBD), port, forward, and aft are used to describe areas of the vessel. The location terms refer to the right side (STBD), left side (PORT), front (FORWARD), or rear (AFT) standing in the pilothouse facing the bow ramp of the LCU.

ILLUSTRATIONS AND TEXT. Locator views are included wherever necessary. An arrow is used to show the general location of the equipment referred to in the text. An arrow connects the point of interest to an overall view of the equipment. Callout numbers identifying parts appear on the art and in parentheses in the text.

PIPING DIAGRAMS. Piping diagrams show the general location of valves, diverters, pumps, etc. Piping between these locations is functional and may not reflect the "as installed" piping. In small areas where a number of items are located, you will see a circle with a note (for example, SEE DETAIL A).

The detailed diagram will be found after the first sheet and will be labeled to match the note. See the table below for a legend of piping symbols used.

SECTION I. GENERAL INFORMATION

1-1. Scope. This is an operator's manual for the 2000 Class Landing Craft, Utility (LCU) (See FIGURE 1-1).

The LCU is designed to transport cargo from ships offshore to shore and to transport cargo to areas that cannot be reached by ocean going vessels. The LCU can carry rolling stock (trucks, tanks, and other vehicles) and dry cargo. The vessel can operate in coastal waters and on the open ocean. It can beach and retract itself on remote coastlines and undeveloped port areas. Because of its shallow draft, the LCU can carry cargo from deep drafted ships to shore in ports or areas too shallow for larger ships. The LCU is also capable of deploying overseas under its own power.
