bit of a funny one today. i was using my track saw today to cut down a door. the saw is a 110v model. conected through my ctl midi. the saw had zero power whatsoever. now i did have 3 extension leads to my transformer. so that probably explains that. but i then managed to get a closer power point so i was using just 1 extension lead. still it was down on power. i had to take 3 runs to cut through the door (door is 45mm thick) and the saw even then taking approx 15 - 20mm passes was bogging down and making really hard work of it. the blade is a low tooth count trend craft pro.

any ideas?

incidentally.... there was an awfull lot of blade marks after the cut. the saw is adjusted to the tracks as per the instructions with no play.
 
What wire gauge are your extensions? Here in the US you'd want 12 gauge. Not sure what the metric equivalent is. I'll look it up when I get home if someone else doesn't jump in
 
As Wow asked , what gauge cable are you using.  Needs to be 2.5mm and the longer your extension the bigger the power drop. I use some trend blades and have never had any issues with the quality of the cut.

Try turning the suction down a little on the midi or plug the saw directly into the transformer and not through the midi. I've had this and I think it was because the socket on the transformer didn't have enough juice for them both.
 
cool ill give it a shot.

out of interest if i had a larger transformer would that make a difference? the one i used today was a 3.3 kva transformer.

dunno what gauge wire.... how would i tell? it was just the standard sort of extensions i think. probably something like this

http://www.ebay.co.uk/itm/EXTENSION-SITE-CABLE-15M-32AMP-110V-VOLT-2-5MM-LEAD-WALTHER-Connections-/161428156580?pt=UK_BOI_Materials_Supplies_Electrical_ET&hash=item2595de30a4

they was 3 together and all straightened out so not still coiled up at all. would that really drop the power as much? ill have to try the saw and vac in seperate sockets and see what that does.

what was weird was it was as if there wasnt enough power so the saw started up and then seemed to slow down from its full speed by a quite noticeable amount
 
If I understand your last post...it sounds like the speed might be turned down on the saw.  Can you check that?  Extension cables can really make a big difference.  The longer the run the larger the cable needs to be.  There's resistance in the wire and alot at the connections.  Avoid using them if possible.
 
Fin as to transformer size i'm pretty sure it wasn't that long ago that someone said festool recommend 5kva min if using a saw with DE .

I'm quite lucky on the site im currently on as they have 3 - 5kva trannies to use. Also if i need to work any distance say over 10ft away from the transformer, then i start out with a 32amp lead and then step down to 16amp right by where i am working.  [big grin]
 
The other issue I've had and my saw is not an req it's the model before. But there's two bolts at either end which allow sideways movement parrallel to the guide rail. I've had these work loose and the saw doesn't cut straight and jams so it seems like it's struggling.

Same here I've been using a big 5kva one for a few months now and the saw runs better
 
hmmm yea makes sense like. i think next time ill try it conected to one transformer socket and the d/e connected to the other.

i had tried using it with the next size transformer down.... it didnt like that.

nah the saw was set to top speed. as i thought the same. it was almost as if the saw had developed a bit of a stutter...

 
as for the transformer problems. ive not noticed any problem when running my router through the d/e though that was with no extension leads.

router is about 2200 watt i think
 
i was at the festool roadshow tour yesterday and they confirmed id be better running my saw with a 5kva transformer.

cheers for the help chaps.

That's what labourers were invented for [emoji3] [emoji3] [emoji3]
 
i think i might persevere with the littler transformer then.... more than twice as heavy eeek
