Equipment operation is allowable with minor leak (Class I or II). Consideration must be given to the fluid capacity in the item/system being checked/inspected. When in doubt, notify the supervisor. When operating with Class I or II leaks, continue to check fluid levels as required in the PMCS. Class III leaks should be repaired using tools available, if possible. If not, use "Not Fully Mission Capable" column criteria.

Failure to fully retract the articulator cylinders prior to stowing can result in serious damage to the cylinders and launch frame. Always ensure the articulators are fully retracted before stowing.

The crane stabilizer feet and spreader pads should not be deployed on uneven ground, which would cause the feet to rotate to an angle greater than 1:8 locally.

Operate the control levers in a smooth and considered manner. The speed of the working movements is determined by the degree to which the control lever is moved.

When operating the crane, heed the symbols on the control levers.

Chapter 3, GENERAL DRILLS, contains operating procedures and practices for various facilities of the DSB, e.g. tail-lift, crane, launcher, bridge modules, etc. These detailed procedures should be practiced and understood by appropriate members of the crew, so that they have become second nature by the time that an actual bridge is being built.

Chapter 4, BRIDGE BUILDING, contains all the procedures necessary to build a DSB bridge.

Procedures covered include: the positioning of launch vehicle and trailers at the bridge site, setting up the launch vehicle, building the launch beam, building the bridge roadway and retrieving the launch beam. It also covers post-build activities, such as bridge inspection and equipment stowage.

Chapter 5, BRIDGE RETRIEVAL, contains all the procedures necessary to retrieve a bridge after use.

Chapter 6, BUILD SEQUENCE FOR 40 METER BRIDGE, is a tabulated sequence of instructions for all the critical tasks necessary for constructing a DSB bridge, 40 meters long.

Chapter 7, OPERATION IN BACK-UP MODE, provides an overview of the facilities available to the bridge crew in the event of loss of electrical power. It also includes procedures for manual operation of hydraulic controls.

Chapter 8, PREVENTIVE MAINTENANCE CHECKS (PMCS), contains illustrated tables detailing the sequences of checks to be carried out before, during and after DSB operation. It also contains general procedures for lubrication and fluid top-up operations.

Chapter 9, FAULT-FINDING & OPERATOR TROUBLE-SHOOTING, Introduces the Built-in-Test Equipment (BITE) facilities on the launch vehicle and contains other miscellaneous procedures, which can be used by the crew to isolate and diagnose faults.

Chapter 10, OPERATOR MAINTENANCE, contains procedures for replacing simple electrical or mechanical components and adjustments.

Chapter 11, DSB TRANSPORTATION AND LOADING PLANS, contains procedures for loading and securing the DSB components on the launch vehicle and trailers.

Chapter 12, OPERATION IN UNUSUAL CONDITIONS, contains procedures for operating the launch vehicle and bridge in severe conditions.
