DUE TO IMPROPER MATERIAL CONSTRUCTION THE HYDRO-BOOST FLUID RETURN HOSE MAY NOT BE CAPABLE OF WITHSTANDING THE TEMPERATURES AND/OR PRESSURES EXPERIENCED WITH THE HYDRO-BOOST SYSTEM. ALSO, THE HYDRO-BOOST FLUID HIGH PRESSURE HOSE ASSEMBLY MAY HAVE BEEN MISLOCATED, ALLOWING THE ASSEMBLY TO CONTACT THE FRAME SIDE RAIL. ABRASION RESULTING FROM CONTINUED CONTACT ALONG WITH IMPROPER MATERIAL CONSTRUCTION MAY CAUSE PRESSURE HOSE FAILURE. EITHER OF THESE CONDITIONS MAY CAUSE HYDRO-BOOST FLUID LEAKAGE, RESULTING IN THE LOSS OF POWER ASSIST FOR THE STEERING AND BRAKING SYSTEMS. COMPLETE LOSS OF STEERING OR BRAKING WILL NOT OCCUR SINCE BOTH SYSTEMS WOULD REVERT TO MANUAL OPERATION.
