I don't care to work in those temps and if I can avoid it I do, but sometimes we will get several weeks of that over the course of a winter and I can't afford to miss that much time, nor can my staff. Customers are understanding to a point, but there project needs to be completed on time. In all honesty you do get used to it and learn how to dress for it. Finger tips are the hardest to keep warm while maintaining at least some dexterity.
As for engine oil I use 5w30 in my Chevy. We plug in to a block heater when it's colder than about -20, but I built a garage last year and I keep my vehicles in there. Even being unheated and uninsulated there is never a need to plug them in.
I work in the cold enough to know that machines don't care for it, but this is the first time I've had a tool refuse to operate. Because the tool has so much power and yet did not draw enough to trip the breaker(or simply turn the blade as it should have) I wonder if the electronics in the Cuprex motor were acting as a protective feature and not letting the saw draw enough current to overcome the resistance in the stiff grease and spin the blade.
I have emailed Timberwolf and I fully expect that I will hear back from them on Monday. Their service has always been very prompt in the past. I will be sure to post the results.
I heard back from David at Timberwolf and the trouble I've had with the cold weather is new to him. He suspects that the electronic start-up module, it gives the saw it's soft start feature, is not allowing the motor to draw enough current to offset the increased resistance created by the cold weather. He also suspects that once the saw is used more, breaks in and the brushes fully seat it may be better able to handle the cold. All in all his thoughts mirror mine and I find his answer acceptable.
It was -35 yesterday morning and the saw didn't work but did get closer to normal speed than my first cold weather try.
It was -23 this morning and the saw worked perfectly. I'm not worried about the cold weather performance at this point. The saw seems to be tolerating it better already than it did at first and if need be I can use an older saw when it's really nasty outside. It is a great saw, I haven't really pushed it's capabilities, but for standard 2x lumber has plenty of power, runs smooth and the weight is not really an issue. I will certainly have times when I will need the capacity and power and be glad to have invested in it.
bengt: Oh please the ks60 is better in every way. 60 degree miter in both directions. Bevels past 45(essential in a saw that must cut on the flat) Bigger blade more capacity. The Metabo hpt has 57 degree miter max and 45 bevel max.

abdon: I stand corrected , the angle fence is only attaches with F -Tracks , what confused me was , that the Timberwolf site mentioned it will work with the NFU machine, yes it will work but only I guess when you use the Ftrack , with other tracks Like the KSS L.

glynnco: Did you order from GereedschapPro? I see them as in stock but I'm located in the US and am not sure if they ship here. I sent them an email asking about shipping but it was returned undeliverable...

jonathan: I've purchased a lot of stuff from our neighbours @ GereedschapPro.nl As far as I know they are one of the larger Mafell dealers in the EU. I can recommend them, they usually respond quickly.

lasse: Thanks for the tip! I have own a mafell rail which is 160 cm and one that is 80 cm. Will it work just as well or will I need to buy rail that is 110 cm?
