There are two holes running vertically inside the needle arm.........the needles are held firm by very small screws or hex allen keys.........they may have worked loose over time, if they have fallen out and been lost, it is a call to your  local Pfaff dealer for advice......be sure to quote model number.
Your User manual may have a diagram to assist.

Have you ever changed the needles since buying this machine ??
Needles ought to be changed every 6 - 8 hrs of sewing, and more often with heavy or abrasive fabric.

I can't find the way to change the left needle.


You can order a manual here - http://www.sewusa.com/Sewing_Machine_Manuals/Pfaff_Manuals/794_796_Hobbylock_Instruction_Manual.htm

In the meantime, contact your local Pfaff dealer. Ask if someone can help you if you bring the serger in.

Price of hobbylock 794 in todays market.


Price depends upon how much the machine has been used & what condition it is in. My hobbylock 794 has barely been touched since it was first made and they advised I just throw it out instead when I took it in for a little 'freshening up' at Quality sewing & vacuum in Washington! Everywhere else I've had great feedback that this is a good serger, so check out what similar machines are selling for on Ebay... you could get $100~$400 for your trusty serger {depending on supply & demand}.

How do you get the blades to cut on a hobbylock 794 serger


It should just cut. Don't know too much about this machine as I'm new owner, but from what I can gather, either you need a new blade, or the upper knife is disengaged. The metal knob inside the threading area should be turned downwards, engaging the upper knife. The upper knife doesn't usually need replacing unless damaged, apparently. Hope this helps somewhat.

The best I can say is to change all your threads to different colors and get light colored material. Start with tenstion for all set to N - normal and experiment from there. Change one thread's tension at a time, sew a long strip and check out both sides and adjust as needed. Remember to start with new serger needles and a oiled machine. I'm not an expert - I just have had a serger for 15 years.

Pfaff serger stuck


your needle bar has been pushed up and is out of adjustment. You need to take off the side cover, there should be a screw on the back of your machine holding it on. Remove this screw, and remove the cover.You may have to remove the light assembly to reach the screw on the needle bar. Once you can see the needle bar, rotate the handwheel until you can see the screw on the needle bar. Loosen this screw SLIGHTLY until you can turn the needle bar. Hold and rotate the needle bar back and forth as you push down slightly. This will lower the bar.Lower it about 1/4 inch. Adjust the needles by turning the bar so that they are straight across. Tighten the needle bar screw so that the bar doesn't move. Turn the handwheel to see if the threads will be picked up. If not, adjust until they are. Tighten the needle bar screw tightly,reinstall the side cover ,and tighten the screw. Change your needles.Rethead and sew.

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!
