cold wether

[ex-28]

out in shop today -25 outside , scrollsaw wont start till i warm it up and get the heat going , i have the hassman expert from revy   but just wondering what exactlly it is   that makes it not start , i have a sander on the side of mine and i can spin the motor manuall with it , even with that it wouldnt go , i loosed up the bushings a little bit but no luck , so just wondering what causes this is all ?

it works fine once i warm it up .

it could be the grease being so cold out might be freezing it up i would put a heater on for a couple hours so it will warm it up for u then u could go in after a couple hours and use it  hope this helps u out

ya i had heat on , also took my heat gun to it and the outside mtor caseing was nice nad warm but still wouldnt start up , after   shop heater on an hour it was fine.. weird as it doesnt even try to spin or anything

I agree with Jason on this
The grease is probably becoming to thick when cold
and causing it to bind.
(Being you stated once it warms up it runs fine)

The motor has bushings in the ends of the case that the armature shaft rides in, so heating the motor case probably doesn't get enough of the heat to the bushings and this is probably why you have to wait  for the room to warm before motor runs.
There are also other bushings and perhaps bearings in the arm mechanism that maybe having the thickening of grease problem also.

If it was something more mechanical causing it,  seems like the cold temperature shouldn't make a difference rather it runs or not.

I would just let the workshop come upto temp first before trying to work.

hope this helps

Well this is the first time I ever heard of a piece of machinery not starting because of the cold.  Oh well....Live n Learn huh?  Danny  :+}

P.S.  My first thought after reading your post is hey its time to check into buying another scroll saw.  My 2 cents....  :+}

it is great you got you a good spot to work in maybe you can keep it warm in there   on your saw i had a shop fox do they same thing  it is not cuz th greasee  it has sumthing do do with the brushes  they get frozen moisture in beteen them is my guess  or they get stuck and the engery cant move them  kind of the same reason your car dont want to start in real cold   i had 2 saws the same and only one wood do it  its nuty for sure
