quiz about a mitre saw and a dust extractor

For the first time ever this morning I hooked my Hitachi mitre saw up to my old Arlec dust extractor with a peculiar result. The vacuum would auto start but it wouldn't turn off. How come? I tried some other tools and it worked fine. Does it know I just ordered a nice new quiet Nilfisk dust extractor and is protesting or is something else wrong?

Cheers

Jeese! well that went off like a lead balloon eh. Anyway the answer is the saw is equipped with a laser so the vacuum was sensing a current draw and not shutting off even though the saw was stopped. Anyway little thing that slipped past me for a while.
Oh well.

Cheers

See. You didn't need us after all:wink:. Glad you worked it out and one to remember.

I worked it out in about 5 mins, that's why I posted it in the quiz section:D

My new Nilfisk Atto 30XC just arrived. It is smart enough to know the difference and switches off even with the laser turned on. And as a bonus the noise level is 59db as opposed to the Arlec which was up in the 'my ears are ringing after a minute' noise level. It's barely audible through a closed door. Time to toss the old one.
