A materials handling vehicle is provided comprising: a support structure including a fixed member (230); a movable assembly (300) coupled to the support structure; a hydraulic system (401); and a control system. The support structure further comprises lift apparatus (222) to effect movement of the movable assembly relative to the support structure fixed member. The lift apparatus includes at least one ram/cylinder assembly (222). The hydraulic system includes a motor (301), a pump (302) coupled to the motor to supply a pressurized fluid to the at least one ram/cylinder assembly, and at least one electronically controlled valve (420) associated with the at least one ram/cylinder assembly. The control structure may monitor a pressure of hydraulic fluid within the hydraulic structure and to implement a response routine if the monitored pressure of the hydraulic fluid within the hydraulic structure falls below a threshold pressure. The control structure only implements the response routine if said support structure is determined to be lowering at a speed equal to or above a predetermined speed.
