Techlite Bar Warped

[Artemis]

My 16" techlite seems to have warped. The bar and saw are brand new, only seen about 14 tanks or so. I know for a fact that the bar has never been pinched, bent, or been under any amount of force enough to bend it, unless the techlites are very pathetically weak. Last I used it, I was only limbing and the saw cut fine. Next time I go to use it on some small logs and the saw is cutting on an angle HARD. Chain is sharp and done properly, so I looked down the bar and sure enough its not only bent, its also got a twist to it. The saw goes overkill on the oil, so I know its not been overheated, as well as no heat coloring. The curve is smooth and consistent too, not like a sharp bend or kink.

My question is, Can a bar warp from being a manufactured defect AND/OR from sudden temperature change (+20C house to -3C outside) ?
Are the techlites laminated? and would that have anything to do with it?

Heat is exactly what causes these bars warp, more often on longer bars. Nevertheless this is why the most of these bars are no longer being produced. They were a good idea but the design was flawed.

It is a bar, not a stick of butter.
Someone bent it.

Yes they are laminated.

They are nowhere near as durable as a solid bar. when the flex at all they stay bent and are easy to delaminate.

These bars are made from two different materials that expand at different rates, when they get a little too warm they warp and will no longer cut through a log.

Yeah.......
Obviously overheated, defective..........

Give us a break..........

Just get a new bar won't cost a fortune the one you have is toast for one reason or another Honestly I've screwed a bar up that I didn't think should have then had replacement bars run for years Some bars are just better than others

I'd just straighten it and go cut more wood.

With a normal bar I would agree. Not so easy with a techlite.[emoji6]

You're right I'm just making this up out of thin air. [emoji8]

 

[HarleyT]

Is that "laminated" air?

 

[Andyshine77]

Delaminated.

Ok the bar is definitely changing shape from temperature. I brought it in last night from -2C, put it on a perfectly flat surface and checked the curve and twist. The curve hasnt changed but the twist has gotten much worse! I should make a video to show it, it's so weird...

I let the bar sit in the same place all night before checking again this morning

Crazy isn't it.

I believe the core of the bar is aluminum which is glued and riveted to the steel shell.

It's new right? Take it back to the dealer.

Always good advice. [emoji106]

I'd exchange it for a normal bar, this Issue is well known by dealers and why most stay away form these pos bars.

I did and unfortunately the bar is not covered by warranty, but they wanted to do sone thing for me anyways and they gave me 20% off of a new bar as well as a new chain. I went down to a 14" as well which i think the t540 likes better anyways

Well at least the gave you a bit of a break. Dealers in the know, would have covered that bar, or not have sold it in the first place.
