POWER TAKE OFF 00-9 Hydraulic Operating Fluid (Turbine Oil) If the Dump Rise Operation is Disabled by Itself If the body (cargo deck) is kept being dropped and the “Rise” operation of the body (cargo deck) is disabled by itself, inspect the cause of rise disabled, fully identify the status, and execute maintenance and repair in accor- dance with the flowchart of the “Defect 1”. Dump body rise disabled” of Chapter “Troubleshooting”.
After maintenance and repair, if there is a hindrance in subsequent work advance because the “Rise” operation is disabled by itself or when the hydraulic circuit is in the following states (1) and (2) after maintenance and re- pair, raise the body (cargo deck), take safety measures for preventing drop, and continue the work according to the following (item of the existence of hoist or crane equipment) methods. 1. The body (cargo deck) rise is disabled due to the air mixture into the hydraulic circuit resulting from insufficient hydraulic operating fluid immediately after repair for oil pump replacement. 2.
The body (cargo deck) rise is disabled due to the air mixture into the hydraulic circuit resulting from insufficient hydraulic operating fluid immediately after repair for leak of hydraulic operating fluid. When hoist or crane equipment is provided 1. Firmly actuate the parking brake and apply a scotch to the rear tire. 2. Set the engine to the stopped state. 3. Set the dump lever to the “Up” position and apply a wire with ample strength to the front of the body (cargo deck). 4. Slowly hang a wire (tensile strength of 1,000 kg (9,807 N)) by a hoist or crane. 5.
After having drawn up the body (cargo deck) to the most raised position, prevent the drop of the body (cargo deck) by the safety rod and the safety strut and check safety. NPA0020E Legend 1.
