Director,
The replacement of just the Z-lock lever entails the total removal of the Z-lock from the awning tube. You can replace just the lever, but there is probably either an obstruction, jam or corrosion inside the lock that caused the breakage in the first place.
I would recommend replacing the entire Z-lock, as the labor is actually less to do so than just replacing the lever.
Here are the abreviated steps:
*fully extend awning and set the rear rafter arm
*remove and discard the bolt assembly holding the casting to the lock.
*rest the forward end of the awning on a ladder and let the front arm rest on the ground
*drill and remove 4 rivets holding Z-lock to the roller tube, then remove the lock
*insert new lock into roller, align holes and replace rivets
*open Z-lock (downward position), rotate the roller so the lock lever is facing down
*bring up head casting, align hole and insert new screw with lock nut and tighten
*your DONE!
PS: IT helps (a lot!) to have a second person help you with this!
Operation:
Z-lock should be in open (down) position to deploy awning and should
STAY
in that position until you want to roll up the awning. DO NOT LOCK IT WHEN DEPLOYED
To retract the awning, close Z-lock (forward and up position) and close the awning
Be sure to spiral the pull strap and not allow it to wrap straight up on the roller.
That's it!!! Have fun.........................
