Remove the two drive rail hanger
nuts from the bolts, and locate the
two lengths of punched angle iron
into position as shown in Figure 31.
Secure them in position with the two
drive rail hanger nuts.
Ensure that the punched
angle iron does not
protrude further than
the SDO4 SMART drive

interfere with the
