Power cord does not retract immediately - Coleman Powermate Powermate 5000W Generator

You may have to replace the cord reel. First inspect it thoroughly to see if you can find something restricting it from retracting.

With all that's involved in replacing the cord and potential cord reel damage, it's more cost effective to just have the entire cord reel, complete with new cord, replaced. Less time consuming thus less costly to you. Hope it helps!

If you pull out the power cord 5 - 10 cm from the base, it should begin to retract.

Sometimes you can help get the springs working again, by gently pulling the cord out a little further and then let it slowly in while pushing the cord retract button.

since the machine is a bernina, the machine probably needs to
be checked at a sewing machine shop, to see why the power
cord won't retract

The retraction mechanizm is likely jammed. Mostly likely the cord has jumped it's groove in the retraction wheel/hub. If you are good with tools there is a 70% chance you can get it to work again with a basic DCR operation. Most mechanical problems can be solved using this simple rule: Dissassemble Clean and Reassemble.

CAUTION: The retract mech has a powerful spring inside, avoid exposing. Most retract mech units are rivoted closed so consumers won't poke thier eye out.
CAUTION: UNPLUG THE UNIT

Open the unit from the bottom and the top lid of the canister should come off.
The retract mech should be obvious as it is where the cord comes into the unit.
Look for the cord being bound by iteslf either on top or underneath (lie two cordes in one groove)
Remove any binding.
If you see no debris or obsticals for the cord to retract (where it is getting stuck)
Your spring could have sprung!
Do you feel and retract at all?
Can you locate the releae mechagnism?
Does the Release button seem to function? When Pressed it should take pressure off of the cord hub.
The retract mech may need replaced. Overall the cost will be about $60 for parts.

Pull cords are all pretty similar so if you've seen one then etc.....
Does the cord retract?
If it's a broken spring then the pull cord would not retract.
If it is retracting then it's probably dirt, grass clipping interfering with the spring loaded locking lever.
Either way the only way to be sure is to remove the top cover and inspect it visually and clean it out and spray some lubrication on it.
You should be able to do this without taking apart the actual cord and retracting coil spring. It should come off as a unit.

Once you have inspected it if you you have any other questions please let me know.
Hope this helps.

under the knob to press to retract the cord there is a screw,
slacken it ad try to adjust it again.

The button has two parts - the inner part (button) and the outer part (surrounds the button). The press the outer part to deactivate (pop out!) the inner part.

It took me a while to figure this thing out, but I was glad the vacuum wasn't broken.
