1.0 VISUAL INSPECTION. Complete the following inspections prior to applying power to the CMU or the rear enclosure. Remove the CMU side and front guards to aid in visual inspection. Record the results of this inspection in the data sheet. If item is satisfactory without adjustment or repair, check the SAT box on the data sheet; if repair or adjustment is required, check the “SAT w/Repair” box on the data sheet.

1.1 CMU. Note: Part numbers given without accompanying reference drawing are from reference (1)

a. Verify that the safety cover assembly (pc 48) sits entirely within the 25.50/25.44 width of the upper frame top plate (pc 59). Recycled safety covers shall be allowed to extend beyond the top plate by no more than

p. Open the door to the 45° position and verify that both detent rods reengage the holes in the hinge pin brackets and hold the door in the open position when the latch handle is released.

q. Verify that the door assembly does not hit the safety cover in the open position.

r. Cycle the door one or more times from open to close to open. Observe the hoses and wires on top of the door to assure there is no kinking or pulling.

s. Verify visually that the cables and hoses under the ram are properly routed and secured as shown on reference (1), section 46-A. Verify the following:
