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 need a manual for a Pfaff Hobbylock Serger 4762, where can I find one


I can't find a manual for this model, however there is a general hobbylock book http://sewingonline.co.uk/library/know-your-pfaff-hobbylock.html which would certainly be a good start.

You may find best source is to contact Pfaff locally and source it from them direct.

You could also try www.diplodocs.com, I can't see this manual but if you go through similar model numbers manuals you may see one very similar. Overlockers/Sergers are very similar in many ways so once you've mastered one, the next one is pretty straight forward. Four tension knobs, 2 needles and 2 loopers is the norm - to get a three thread stitch you just don't thread one of the needles. Tension adjustments alter the stitch formation, and you should have a stitch length knob on the right side of the machine along with a flywheel and if it has it, differential feed (which controls the feed dogs so you can stretch, or compress the fabric as it goes under the foot).

There are some good general how to use a serger books in the marketplace too which should help. Threading up, many machines have a diagram inside the front flap, colour coded dots on the knobs, eyelets and loopers. And oiling points are often marked on this diagram too. But basically oil the two loopers where they slide/move on another metal part. Some good info here too http://sewing.about.com/od/sergersoverlock/Sergers_Overlock_Sewing_Machines.htm

Hope this assists you a little.

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 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!
