STANDARD TOOL REQUIREMENTS
The following are general practices regarding the use of tools:
Always use the proper tool kit and tools for the procedure being performed.
Ensure that tools are clean and lubricated to reduce wear and to prevent rust.
Keep track of tools. Do not be careless with them.
Return tools to toolbox when finished with repair or maintenance.
Return toolboxes and tools to tool storage when not in use.
Inventory tools before and after each use.
Some maintenance tasks may require special or fabricated tools. The "Initial Setup" of the procedure will specify
any special or fabricated tools needed to perform that procedure. Use these special tools only for the
maintenance procedures for which they are designed or called out. If you are unfamiliar with a required tool, see

TAGGING WIRES AND HOSES
Use marker tags to identify all electrical wires, lines, and any other parts which may be hard to identify or replace
later. Fasten tags to parts during removal by wrapping wire fasteners around or through parts and twisting ends
together. Position tags to be out of the way during cleaning, inspection, and repair. Mark tags with a pencil, pen,
Whenever possible, identify electrical wires with the number of the terminal or wire to which it connects. If no
markings can be found, tag both wires or wire and terminal, and use the same identifying mark for both. If you
cannot tag a wire because it must fit through a small hole or you cannot reach it, write down the description of the
wire and the point to which it connects or draw a simple diagram on paper. Be sure to write down enough
information so you will be able to properly connect the wires during assembly. If you need to identify a loose wire,
look for identifying numbers near the end of the wire, stamped on a permanent metal tag. Compare this number to
wire number on the appropriate electrical schematic.
Identify lines when you are taking off more than one line at the same time. Mark tags with points to which lines
and hoses must be connected. If it is not obvious which end of a line goes where, tag each end of the line.
Identify and tag other parts as required by name and installed location.
END OF TASK
Use low-wattage soldering gun when soldering electrical wires, connectors, terminal lugs,
and receptacles. High-wattage soldering guns may damage parts by overheating.
Solder connection must be bright and clean before soldering. Remove dirt and grease with a wire brush or a
pocket knife. Solder used must be of lead alloy with soldering flux. All wires, parts, and soldering gun must be
tinned for good connection and maximum transfer of heat.
To prevent overheating damage to electrical parts when soldering and unsoldering connections, hold bare wire,
lead, or terminal lug close to soldering point with long roundnose pliers. Pliers act as heat sink and absorb excess
