TM 5-4210-233-14&P-1 2-15.  EMERGENCY AERIAL PROCEDURES - Continued c. Rotating Ladder Turntable. WARNING The   ladder   must   be   secured   to   prevent rotation    of    turntable    in    either    direction before     the     hydraulic     motor     and     brake assembly  are  removed.    This  prevents  the ladder   from   rotating   out   of   control   when brake is removed.  The guy ropes should be placed   on   the   lower   chords   of   the   ladder sections. (1) Secure ladder with guy ropes to prevent turntable rotation when brake is removed. (2) Remove the hydraulic motor and brake assembly from planetary drive. (3) Use the hand crank provided (located under the ladder control panel) to align ladder with bed locks. NOTE Be  sure  to  position  ladder  in  line  with  bed locks;  ladder  cannot  conveniently  be  lifted manually. d. Lowering Ladder. (1) Turn the black knob on the hydraulic hoist manifold block, located under the step at the base of the aerial ladder.  Turn the knob counterclockwise. This will slowly lower the ladder. (2) To stop lowering the ladder, tighten the black knob. e. Raising Outriggers. (1) Remove cover on each jack stand.  Loosen the two bolts slowly and evenly, one revolution at a time. This breaks the seal on the cylinder inlet and allows oil to be released. (2) The outriggers can now be lifted manually. (3) Tighten the two bolts.  This will keep the outriggers raised after a vacuum forms in the cylinders. NOTE The   outriggers   can   be   manually   retracted   by   engaging   the hydraulic   valve   and   pushing   in   the   corresponding   outrigger beam. 2-62
