Deactivation of the hydraulic controls does not prevent the blade, boom swing, or auxiliary circuit functions from moving under gravity or other external forces. Gravity or other external forces can move the blade, boom swing, or auxiliary circuit functions suddenly if a hydraulic control lever is moved.Personal injury or death may occur from sudden machine movement.
Park on a level surface. If it is necessary to park on a grade, chock the tracks.
