Where can I find a tension knob assembly for a Pfaff 295-1?

many presser foot shafts have a adjuster knob around the top that increases the spring tension that pushes the foot down
check around the top and turn that ring

nothing to do with bobbins
A lot to do with insufficient needle thread tension

This machine has an electronic thread tension control. You'll only be able to adjust the tension for the current stitch, until you turn off the machine or change your stitch selection. Press the Setting button and use the Up/Down arrows on the wheel to get the move the setting selection box on the Thread tension line, if needed. Use the Left/Right arrows on the wheel to increase or decrease the tension. Press OK (the center of the wheel) to save this tension. Test the tension on a scrap of your project and repeat the steps until the thread tension is appropriate for the project. Press Info when in the sewing mode to see the current thread tension.

The manual for the Pfaff Quilt Expression 4.0 (and a couple of other models in the Expression line) is available from Pfaff here: http://www.pfaff.com/SiteMedia/PFAFF/Products/Machines/Support-manuals/expression_2_3_4-manual-EN.pdf?ext=.pdf . See page 2:16 (page 28 of the PDF) for the details. Pages 2:10-2:11 show the buttons for the Expression 4.0.

I hope this helps.

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.

This is the only graphic I could find, but it is for a different model.

The numbered knobs are the tension setting 4 - 6 is the normal range.

You need to get the tensions set correctly, sounds like either you have not gone through the tension discs or the top tension is too loose.

Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.

Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.

Good luck,

Tension assembly test. To do this test. Pull the threadthrough the tension assembly and test it to make sure the tension is workingcorrectly.
(To do this test, adjust your tension setting to normal or medium or 5 orsomething in the middle. Raise the presser foot and pull the thread through thetension. It should pull easily!! Lower the presser foot and pull the thread. Itshould pull noticeably harder.)
If it doesn’t work this way then you probably have a pieceof thread or lint stuck inside the tension discs. To remove it, turn thetension to 0 zero and raise the presser foot.Using a small screwdriver, openthe space between the discs and spray with canned or compressed air( a needle will work also). The stuffshould come out. Do the tension test again to make sure you got everything andthen try sewing again.

all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.

You don't have the thread in the take up lever or it is not in the tension. Rethread it , Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
