It depends on what kind of spray gun you have. If you have a HVLP gun the pressure doesn't have to be as high, but you need a compressor that will keep up. The pressure is usually pretty low on these guns, about 15 PSI or less. The paint manufacture will usually give you a recommended pressure to paint their paint. A normal (old style) suction type gun takes more pressure, about 50 PSI. If you are asking this to decide on a compressor size, you will find that a one horse motor on a two cylinder compressor will not keep up. The newer supposedly five horsepower compressor will not keep up consistant pressure either. You need a five horsepower that runs on 220 and driving a belt driven two cylinder compressor minimum. You can get by on less, but have to wait half way during a coat on a car to wait on the compressor to catch up. This may be o.k. if you are just going to paint one car, but if you are looking to do this consistantly, then I would get a five horsepower motor on a two stage compressor. Make sure you drain the air tank of water and use a good air filter to remove moisture from the air before trying to paint. Hope some of this helps you.

I have an old wizard citation.. it was working great and then it stopped sewing and just makes a noise, but it still works manually.

If it's an old mechanical machine, it has probably seized from old, dried oil that acts like glue on the moving parts. Get some liquid Tri-Flow Synthetic Lube and, while manually moving the handwheel, apply a couple drops every place that metal rubs metal. Do NOT oil belts, rubber, or synthetic parts. Then apply hot air from a handheld hairdryer into the internal mechanics. You may need to repeat the process several times before it moves freely.

How and where do I put oil in my hobby 303 sewing machine? Can I use WD40 to oil my sewing machine?

Don't use WD40, as if it gets onto paint or plastic it could damage the surface.

Use clear sewing machine oil.

You can purchase a manual for this machine from here - the manual will identify the oiling points, for a mechanical machine there is usually a point within the rotary hook area that will need lubrication (and regular cleaning of lint and dust).

YOu can find general machine maintenance tips here

Your machine may have marked oiling points with a red dot - each machine is a little different hence the manual is always best reference point.

Bernina 730 Can't open top cover !

The problem is that of a stuck piston detent on the pattern selector support that snaps the top cover closed.
  1. Open the light cover
  2. Apply pressure with thumbs on the bottom edge of the top cover on both the right and left sides of the cover. The cover should pop up...Too much pressure on the left side, (if this thing is really stuck) and you might break the top cover at the thread tension slot. Be careful here....
  3. Add a drop of acetone (fingernail polish remover) to the piston detent and work it free by pushing it back and forth. Avoid getting any acetone on the painted surfaces of the machine.
  4. Continue to work free, repeating with a few drops of acetone, and wipe clean. Don't oil this part. It was a petroleum product combined with a galvanic process (aluminum and steel) that caused the problem in the first place, not to mention age.
  5. Use DTE Heavy Medium oil rather than a white or clear oil when you lubricate your machine. White oils are unstable and will oxidize (decay) much more quickly. Also avoid 3 in 1 oil and stuff like WD40....very bad....
  6. Oil 1/2 a drop on those prescribed areas. Too much oil is more harmful than not enough....
  7. Contact your Bernina dealer for this oil.

I have a viking 980. The decorative stitching does not work. I have no manual. Can any one tell me how to use these stitches. I think I may have just forgotten what to do.....:( Thanks! ChampionChicka

If the decorative stitches you are talking about are on the card that you insert into the machine, the problem can be that the sensor is not seeing the white squares on the bottom of the card itself. Take white paint or a white out liquid paper and "paint" the white squares at the bottom of the card but only the white squares. That will help the sensors "see" which card you have inserted. If that doesn't do it, your sensors are bad and they are not available. Make sure the paint is dry before you put the card back into the machine.

Husqvarna Prisma 980 decorative stitch cassettes don't work

On that machine, the cassettes aren't actually computer chips. Each cassette has a little spot of white on a certain little area you must find (top right I'm pretty sure). Look in the machine at that point. There is a sensor that looks for that white spot, and as it identifies it, it changes stitches according to that cassette. Either the sensor is blocked, gone bad, or you can put a fresh coat of white paint on with white out. I hope this helps.

Buttonhole sensor

On my foot the white line is painted on a raised indicator on the top side of the plastic housing. You might be able to feel it if the paint isn't there.
