1. Unlock the gate (see Figure 1 & 2).
Open the manual jack access cover located at the middle of the gate and remove the handle

the handle onto the jack nut and crank the jack all the way to unlock the gate. (Turn clockwise.)

Open the manual drive cover on the capstan drive enclosure, release the catch on the lid, and
lay the lid back. Remove the guard on the manual drive crank. Insert the manual jack handle
