Makita Disc Cutter problem

Richy D · Post by **Richy D** » Fri Apr 17, 2020 9:43 pm

Hi all I’m re-building a Makita EK6100 disc cutter and am struggling to connect the short circuit cable as I don’t know where 1 of the 2 ends go at the choke lever end of the cable. Both are female spade connectors and 1 is bigger than the other. I know the smaller one fits onto the end of contact spring but am struggling with the other! My guess is that it somehow completes a circuit when the choke lever is moved but can’t see anywhere obvious that it would push onto? Any help would be greatly appreciated! Thanks

What did google bring up? (I just tried and came up with lots, but I have no idea exactly what I am looking at)

Short cable that makes a circuit, or cable that short circuits the ignition to stop the engine?

Why would the choke be connected to the ignition?
All the petrol engined kit I've worked on has an ignition switch, a throttle lever of some sort that controls the engine revs, and a choke lever or control that sets the mixture "rich" for starting.
I can't remember any of them having the choke connected electrically to anything. Doesn't mean it's not mind, just that I've not seen it.

When pulling things apart, take photographs, or make sketches. We all think we know how they go back until we come to it!

Photos might help now here.

The cutter looks a lot like a chainsaw motor. The only thing not touched on is the lead from the magneto which I think is connected to the on/off switch so the pull cord does not work until it is on.

Exactly, the switch earths the primary of the mag. (Although I think they're generally a bit more complicated than an old fashioned mag these days and they generally call them an "ignition module" IIRC.
The switch is more of a "kill switch" than an "ignition switch" as such, although there's no difference in what it does.

Found this Dave, any help https://www.sparepartsworld.co.uk/product/SPARE_EK6100 Diagram 5, area 97

Looking at the manual, https://www.icmsmakita.eu/cms/custom/uk ... _22758.pdf it's a "combination switch choke on / stop"

So it looks like the wire does go to the "choke" which is combined with the ignition switch

The only thing I can suggest OP is to follow the exploded parts diagram either where DWD has linked to or here https://www.icmsmakita.eu/cms/custom/uk ... EK6100.pdf

Sorry for the lengthy delay in replying but I did get it fixed after a lot of head scratching. The bigger female connector slides onto the bottom of the choke cum on/off lever. It completes a circuit when the lever is pushed to the bottom which short-circuits the ignition so stops the engine. It was quite simple to do once figured out and very similar in design to all the other Makita DPC disc cutter saws. Thanks for everyone’s help
