FRS Cchannels of the flatrack must NOT be in contact with the terrain or any object to
prevent altering the critical reaction points of the FRS. Failure to comply could result in
personnel injury or death.
Lower outrigger jacks individually as necessary to level the FRS side-to-side and
front-to-back. The FRS is level when the black ball is under the 0 indicator (a portion of
the ball must be under the 0) before the crane is loaded. Perform a final check of all
three level indicators before placing a load on the crane.
Ensure that both outrigger jacks are taking load.
If FRS is being leveled on unstable/uneven ground, refer to Operating FRS on Unstable or
Uneven Ground (Para 2-39).
(14) Using both RH O/R JACK and LH O/R JACK levers (19) and (20), lower jack cylinders (17) until rear of

(15) Using both RH O/R JACK and LH O/R JACK levers (19) and (20), adjust jack cylinders until
front-to-back level gage (23) shows FRS (24) is level.
