The clutch mechanism is an integral part of the stand shaft. The inner tube is a "friction fit" with the outer tube. Just place your foot on the base of the stand to keep it on the floor, grab the desk portion of the stand and pull it up or down to raise or lower it.

There is only one adjustment, as far as I can see: the height, which works by pulling up on the lever with the concave disk handle. To lower the seat, you need to be sitting on it (or applying downward pressure). I don't see what that big knob under the seat does.

The one that I received from Amazon is not like in the photo. Mine has a small round knob on the extension. The knob at the elbow looks to be like the photo. I don't have any complaints about it.

It's very easy to adjust. My 6 year old can do it. To make it raise, all you need is a broom handle or something like it and push up anywhere on the unit. To make it go down, you still use a broom handle but there is a catch lever you have to push on to release the unit.

The foot pedal raises the chair, it does go up in short increments, but it works great.I have been very happy with the chair.

It should go up and down without too much effort. Did you put the lever correct way?

I think you can loosen the screw that holds the knob and adjust it. I had the same issue. Kind of a goofy design.

With a broom, you can raise or lower the hoop. There is a spring loaded lever that clicks and then go up or down. It's very easy and fast to do. Great.

I am not sure what you are asking Angela. So if you are talking about lifting and lowering the vehicle you just turn the to the right to lift and to the left to lower. If you are talking about holding it in place there is a little round knob at the base where the handle is inserted. when you insert the end of tube into the hole there is a square piece that goes inside the end of the handle tube. After that goes in a little bit, pull the knob straight back. it is spring loaded and you will feel the tension on it as you pull it back. Then push the handle in the rest of the way and let the knob go back in. it will lock the handle in. I hope this helps you. I am not sure what you are asking Angela.

it only raises it a couple of inches. i actually used wood blocks to raise it higher so the bike would level out and relive pressure on my arms.

There are screws in the back of the unit that u need to loosen then u can raise the unit and tighten the screws.

It is screwed down with two plastic clamps that are shaped like the Greek Omega. It raises and lowers easily. The only problem we have with the commode is that it's heavy, which makes moving it a little difficult.

Raise it all the way up, and then it will release and allow you to lower it.. Hope this helps �

you can order a stem riser from amazon. I ordered and installed one - it raised the handle bar height by about 5-6 inches. If you don't like it you can always return it (for free if you're a "prime" customer and the item is prime eligible, which i'm pretty sure it was). I ordered the Delta stem raiser for about $28.

I forgot one important detail....if you look at the left hand cable you'll see a piece of 4" long black plastic under that is the plate where you can adjust your clutch cable...good luck...easy fix.

If you place one foot at the base, pull the pin and pull up on the head rest, it lifts up. To put it down do it the reverse way. Hold the base in place, pull the pin and push the head rest/ seat down
