TM 5-4210-233-14&P-1 4-205.  AERIAL LADDER TENSION CABLES This task covers: a. Adjustment TOOLS REQUIRED EQUIPMENT CONDITION Tool Kit, General Mechanics, Automotive Outriggers Extended (see para 2-14 .) (Appendix B, Section III, Item 1) a. Adjustment. WARNING When tightening the cables do not allow the cable take-up to rotate as this will cause the cable to unwrap and damage the cable and may cause serious personal injury or death. CAUTION Do not overtighten cables.  Overtightening of the cables will cause excessive wear on the cable, sheaves, bushings, and pins. NOTE The ladder must be adequately lubricated before any cable adjustments are made. To check cable alignment, extend the ladder, raise it to 60 degrees elevation, and fully retract it, then lower it back down to 0 degrees elevation.  There should be 114" to 3/4" (6.35 to 19 mm) gap between the front of the base section front crossmember and the back of the lower mid section water pipe flange mounting bracket.  This gap should be maintained for all the ladder sections and should not be any larger or smaller than recommended. Any adjusting or retensioning of the extension cables should start on the base section extension cables. If the ladder is retracted too far back, the front cables on the base section should be tightened as this will draw all the above sections outward. (1) Extend, elevate, the ladder, then retract and lower to see if an alignment problem still exists. (2) If  the  ladder  is  still  misaligned  the  cables  should  again  be  adjusted  accordingly  and  the  test redone to check alignment. (3) Once all adjustments are made to the base section the rear cables should have any excess slack taken out of them with care not to overtighten the cables 4-514
