Clear all personnel from around the dump body. c. Squeeze the hydraulic control lever heed together (see fig. 2-5) and check operation of the body at low engine RPM’s to verify reasonably normal operation. Keep in mind that oil has not been circulated through the pilot valve and hoist cylinder. d. Lower the dump body, release the T-handle, and place the control lever in the N (neutral) position. 2-18
