20 Most Recent Euro-Pro Fast and Easy 420 Mechanical Sewing Machine Questions & Answers

This is usually caused by the needle not being threaded correctly or wrong size needle or wrong thread for the material or old thread, or incorrect tension for the material being sewn.

YOu cant' You used to be able to buy a new unit at Europro for $10. But don't know if they are still in business. I gave up on mine and do it manually.

Wet and dry fine paper rub the walker foot and base for any catching.

Check your tension on reel.

There are several possible causes for this problem.Simplest first. 1) The machine has sat in the closet for three or more months, and the oil has ceased. The fine oil requried for these precision machines does run away, and/or cease up into a grease like paste, causing the parts that move in precise harmony, to be not so precise. The cure for this, is to remove all thread and fabric, and run the machine full speed for about two to five minutes. This heats up the parts and loosens up ceased parts. A good re application of fresh oil helps too.NOTE: Check the needle is Straight by turning the machine a couple of turns by hand and seeing that the needle dosn't hit any metal parts. A breaking needle can cause dammage to the machine or user in when operating at high speeds.2) Tension dials have been knocked out of balance. There is a numbered tension dial on the front of the machine, somewhere along the threads path from spool to needle. if this is too tight, the thread will not leave a loop big enough to catch the bottom thread. Be sure this is set to about 3, usually. It should be adjusted while stitching, when you get to that point.On the bottom thread, on the Bobbin Holder piece that comes out of the bottom, there is a small screw that adjusts tention of the thread comming out. This screw should not be tight, but tight enough. Completely by tactile intuition, this screw should be adjusted to allow the thread to slide out of the bobbin holder smoothly. It must have some tension to pull the thread from it, but not so much that it is noticeable, or take much of a grip on the thread to pull it out. (difficult to describe) These two tensioners must balance so the threads, cross paths, but also pull the stitched snugly into the fabric being sewed.3) Bent Needle, this is a problem if the fabric being sewed has pulled the needle off it's center. If it is not perfectly straight, don't use it.4) Cheap thread can be a problem. If the thread is frayed, or fuzzy looking, it may be that it will not work with as fine a needle you are using. Needles have various sizes and sized holes to feed the thread through, a fine needle needs fine thread, and coarse thread needs a larger needle.These are the primary causes of the threads not looping together properly. I hope this helps.

I presume that you are talking about an automatic needle threader? In this case, first of all check that the needle is correctly in place -- inserted all the way up as far as it can go. Then manually turn the wheel so that the needle is in the high position. If this doesn't fix the problem, then maybe your needle is bent, so replace it.

Be sure you leave a 3-4" tail on the bobbin when you insert it. Hold the end of the top thread, turn the fly wheel toward you until the needle goes down into the bobbin, grabs the bobbin thread and pulls it up. Take both threads toward the back of the machine and pull out about 6". Hold both threads as you take the first stitch in your fabric.

Either your machine was not threaded with the presser foot wasn't up when you threaded the upper thread... or your upper tension isn't tight enough. Good luck.

here is a link for a manual, the manual is not free, euro-pro normally aren't. but it should have the information you need in it.http://sewusa.com/Sewing_Machine_Manuals/Euro_Pro_Sewing_Machines/Euro_Pro_420_Instruction_Manual.htm

have u tried wd 40? and or check presser to see if pin is bent

can u show a video?

It takes some getting used to, to get these to work properly. Practice. First make sure your needle is in correctly and fully. then make sure that when you engage the needle threader the tiny little hook goes through the eye of the needle. If it doesn't it won't work at all. Then follow the instructions in the book. Make sure the thread is on the proper side of the tiny hook.... Good luck
