Hello Everyone,
When I use my King Canada Dust Collector, after ~5 min of use the overload switch mounted on the motor trips and the DC shuts off. The motor is not hot, so it can’t be overheating. I am only using ~6ft of hose, as it is beside and directly attached to my lathe. Could it be tripping because it is drawing to many amps, because of the short hose? Or is it probably a faulty overload? The overload switch is part #45 on this diagram.

i doubt it would be because of the short distance of hose. I can run my DC with no attachments for at least 10 mins (was gather intel on cfm intake).

Bill Pentz says on his website here at point 13 that a “dust collector vendor puts a warning on their dust collectors that they will burn up if run without at least 10’ of flex hose attached.” Not trying to argue for my opinion, just thinking that maybe not all DC’s are created equal.

What’s the amp draw of the motor and what size wire feeds the outlet the DC is plugged into. Also , is the lathe plugged into the same circuit?

I would have to check the above details; I think you may have misunderstood me; the overload that is tripping is on the DC motor, the lathe keeps running even when the DC has tripped.

Sounds to me like there is a bad capacitor on the motor, or is trying to go out…..Mine did the same thing once like you described, and that’s what it was….Is it throwing the breaker, or just tripping the overload switch….? I don’t have an overload swith on mine (that I know of), so if you’re not running two or three machines at the same time, and only the lathe, then it could be the capacitor…And I’m not buying that bit about using a short hose, and you have to run at least 10 ft…..They put those warnings on those machines to cover their own a$$...

Only the overload on the motor is tripping…
Would the capacitator tripping cause the motor overload to trip?

Well….I’m not sure, but it’s possible…How old is the d.c.? I don’t think you said. It could be a couple of things. There could be a bad or burnt wire inside the motor housing that could be causing it to trip…just don’t know w/o getting inside the motor and taking a look….

try it with the hose plugged and see what happens. Dc motors are not air over it wont burn out with the intake completely plugged. and take an amp reading.

I’s hard to imagine that it would be drawing too much air. The test reo suggested should give you a clue. With the inlet plugged, the fan isn’t moving any air…in effect it’s freewheeling with no load on the motor. If it trips in that condition there’s another problem semewhere.

I plugged the inlet partially and it ran fine for an hour…
I guess thats my problem.The motor was quite warm though…

How hot should a DC motor be after running for 1hr?

Have your say...
