To raise a stage of the HI-POD, start at the top.
(This makes sense because if you raise one of the lower stages first, you will never be able to extend the other stages because you won't be able to reach them)
Hold the tube with one hand
Grab the cam-lock with the other hand.
Open the cam-lock (extend it outward)
Now extend the tube with both hands.
(you are able to extend the tube because you have unlocked the cam-lock)
When you find the correct height, hold the tube with one hand (don't let go)
With the other hand lock the cam-lock (extend downward)
Test the lock to see if it is holding the tube.
If the tube is slipping, rotate the cam-lock so the threads tighten and lock.
If you are satisfied, then move to the next collar and start the process again.
To lower the HI-POD perform the above steps backward.
Hold the tube with one hand
Grab the cam-lock with the other hand.
Open the cam-lock (extend it outward)
Grab the tube with both hands. Let the tube slowly slip through your fingers.
(DO NOT LET THE TUBE GO. IT WILL COME DOWN VERY FAST, POTENTIALLY HARMING YOUR FINGERS OR ANYTHING IN ITS PATH)When the tube is contracted to your liking continue with the next stages. Repeat as necessary.
