COMPRESSED AIR USED FOR CLEANING AND DRYING PURPOSES CAN CREATE AIRBORNE
PARTICLES THAT MAY ENTER THE EYES. PRESSURE SHALL NOT EXCEED 30 PSIG AND USE
ONLY WITH ADEQUATE CHIP GUARDS AND CHIPPING GOGGLES.
2-8. CLEANING. Components may be cleaned with low pressure compressed air, then wiped clean with a dry, lint-free
cloth. Components may also be cleaned with a cloth dampened in cleaning solvent, Federal Specification P-D-680.
2-9. WIRING. Tag all wires and cables during removal procedure for correct identification during replacement
procedures. Before a part is unsoldered, note the position of the leads. If the part has several leads, tag each of the
leads before unsoldering any of them. If wiring must be replaced, use leads of the same length and gauge. Never use
replacement wire with a higher gauge number (smaller diameter).
2-10. SOLDERING. On printed circuit boards, use a pencil-type soldering iron with a 25-watt maximum heating
capacity. Make well-soldered connections, using no more solder than is necessary. Do not allow drops of solder to fall
into the unit. Do not allow a soldering iron to come into contact with insulation or other parts that may be damaged by
excessive heat. Do not disturb the setting of any
