Blackout Conditions

TM 5-3810-307-10

Place superstructure cab IGNITION Switch (56, Figure 5-2) to 3 (accessory)

and turn on the APU. Then operate the FRONT AXLE STEERING Control

(55) to straighten the front wheels.

Place superstructure cab IGNITION Switch (56) to 0 (off) and turn off the

APU. Close the APU control box.

Verify that both superstructure and carrier cab IGNITION Switches (56,

Figure 5-2) and (50, Figure 5-1) are in the 0 (off) position. Also verify that

the battery disconnect switch is off.

Blackout Conditions. When driving the crane under blackout conditions, all

normal carrier-controlled lighting, horn, and alarm circuits are disabled by placing the Blackout

Lighting Control (16, Figure 5-1) in either blackout mode. When in the blackout mode, only the

blackout park lights, blackout tail lights, blackout stop lights, blackout driving light, and carrier cab

panel/instrument lights are lit. It is not possible to perform any craning operations in blackout

conditions since all power to the superstructure cab is shut off.

NUCLEAR, BIOLOGICAL, AND CHEMICAL DECONTAMINATION PROCEDURES.

NOTE

The crane is equipped with a bracket for storing

decontamination materials. The bracket is located on

the left side of the vehicle just forward of the hydraulic

tank.

The crane is capable of being operated by personnel wearing nuclear, biological, or

chemical (NBC) protective clothing without special tools or support equipment.

Refer to FM 3-5, NBC Decontamination for information on decontamination

procedures. Specific procedures for the crane consist of the following:

All sealing gaskets, rubber sleeves, sound attenuation materials in the cabs, door

and window gaskets, rubber tubing, coverings for electrical conduits, etc., will

absorb and retain chemical agents.

Replacement of these items is the

recommended method of decontamination.

Lubricants and fuel may be present on the external surfaces of the crane or

components due to leaks or normal operation. These fluids will absorb NBC

agents. The preferred method of decontamination is removal of these fluids using

conventional decontamination methods in accordance with FM 3-5.

Continued decontamination of external crane surfaces with supertropical bleach

(STB) and decontaminating solution number 2 (DS2) will degrade clear plastic

indicator coverings to a point where reading indicators will become impossible. This

problem will become more evident for soldiers wearing protective masks. The use

of STB and DS2 decontaminants in these areas should be minimized. Indicators

should be decontaminated with warm, soapy water.
