The lifter lever on my hobblock 794 will not lift up the pressure foot. It still sews but cannot get the pressure foot to raise.
Screw on pressure foot near the lifter is slack. adjust and retighten.

If you can remove the cover on the left side you will see the presser foot bar. On the bar there will be a screw that may be loose. Turn the handwheel until the needle is all the way down and lift the foot manually until just before it makes contact with the needle clamp and tighten the screw on the presser foot bar.
That should do it.

You have a timing problem which needs a technician to repair. to do this properly, you need some special gauges which, generally , are not found just anywhere. Take it a technician and get an estimate before you leave it.

The needles are changed by inserted the hex wrench into what looks to be holes on the front and left side where the needles go into the machine.I'm not sure what size the hex wrench is but it's pretty small. From the manual,
"Removing Needle: Unplug the machine. Turn the handwheel
counterclockwise to raise the needle bar to its highest position.
Loosen the needle clamp with the allen wrench and pull the needle out."
and
"Inserting needle: When the neddle bar is at the highest position, insert a new needle in the needle holder, making sure that the groove of the needle faces you. Push the needle as far up as it will go and tighten the needle clamp screw." "Removing Needle: Unplug the machine. Turn the handwheel counterclockwise to raise the needle bar to its highest position. Loosen the needle clamp with the allen wrench and pull the needle out."
The machine takes DB x 1, or 1738 needles, and a size 14 needle is recommended.
Hope this helps!

That's the problem seized up use a penetrating oil from the top and work it up and down and it should free up
SOURCE: When I raise the lever the presser foot only lifts
yes, pressure foot lever should stay raised, this sounds like the spring has broken in your machine. if you are comfortable with delving into the machine you could open it up and take a look. alternatively take it to a sewing repair man and get it serviced as well as clean and lube.
