quiz about a mitre saw and a dust extractor

[mic-d]

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?

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.

See. You didn't need us after all. 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

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.
