I own a manual jack version of this excellent lift, but this procedure will work for the air version as well.
Problem: Jack has gotten rather spongy when lifting a bike and won't go as high as it did when new. It also slowly goes down after you raise it. There are no signs of hydraulic fluid leaking.
Solution - To purge the air out of the jack:

Solution - To purge the air out of the jack:
- Manually raise the lift platform to disengage the jack from the upside-down "U" shaped neck that runs across the top of the jack ram.
- With the valve closed, manually grab the top of the ram and pull it up as far as it will go. You may need to unscrew the top of the ram some to give you a better grip.
- Push the ram back down and then when you feel resistance, open the valve until the ram is fully down. You'll hear a hiss as the air is pushed out.
- Close the valve (important).
- Repeat steps 2-4 six to eight times.
