Loading And Unloading A Dump Trailer 100 Dump Controller Return the dump body control to the battery box. Watch for and avoid obstructions such as tree limbs, overhead lines, potholes, etc. and SLOWLY drive the tow vehicle and trailer ahead to spread the material. DO NOT drive forward and stop quickly to “shock” the load out of the body. DO NOT “jerk” the control button up and down to dislodge the load. The proper procedure for a stuck load is to fully lower the dump and dislodge the material by hand. You may need to raise the dump body higher after a portion of the load has been spread to place the remaining material at the rear of the dump body. Stop tow vehicle after all material has exited the dump body. Press and hold button (4) to lower the dump body. (See previous figure.) Release the button when the dump body is fully lowered. Place dump body controller in the storage or travel location. Close and lock battery box. ! WARNING Fully raising the loaded dump body may result in the tow vehicle rear wheels loosing traction. Do not fully raise a loaded dump body or place the entire load at the rear of trailer.
