STEP 5
(Raising The Cross Tubes)
1. It is necessary to first raise the Cross Tubes off the
ground to facilitate Cable routing and final assembly.
ENSURE THAT THE FRONT POST UPPER AND LOWER
SLIDE BLOCKS ARE ORIENTED AS SHOWN IN FIGURE
3.3 ON PAGE 13. BEFORE PROCEEDING.
2. Manually raise the Cross Tubes until the primary Safety Locks
engage and rest on the lock position second down from the
top of the ladder or approximately 6’6” off the ground. It is
important that the SLACK SAFETY LOCK IS CLEARED. The
Slack Safety Lock must never rest on the Safety Ladder. See
Figs. 5.1.
3. The Columns and Cross Tubes will now be in position
and spaced properly for the Runways. (See Fig. 5.2)
