Has anyone tried Rotatech chainsaw chains?  A friend who uses them tells me they are good, anyone tried them? 

 

Also.....had chainsaws for a good number of years. Considering a cordless one for logging up on the garden etc. Stihl MSA 220 c  or  EGO CSI 400 E are ones I've been looking at .......    opinions would be very welcome.

Another user of Rotatech, i found them very good for the price, occasional hard tooth, but manageable, bars are ok too. If mooney is tight go for it.

Thats an absolutely shit design isn’t it? How much would a dedicated reservoir have added to the cost? Bugger all, not to mention the chance for cavitation if a careless op lets the level drop too low. 

Yes crap design. But crapper due to the one shot of oil per pull down of the bar. So the bar gets the same volume of oil for a 2" twig as it does for 14" of hard crotch. If the oil is low enough to not feed bar you have bigger issues as machine would not work.

That’s what I meant by chance of cavitation. As the reservoir lowers, air may get drawn into the system which causes cavitation and damage to motors and pumps.

To be honest you would have to be blind as you stand near the fluid level gauge with your hand above it.

Thanks to all who gave information and advice....much appreciated.

I decided on the electric Huski 420EL with the 16" bar.

If I replaced the bar with a 14" bar would it improve performance?

I run the same processor and it's not as bad as it might sound. There is an excellent sight gauge to see the oil levels so no risk of running the oil low. Also it means you are always taking out the worst of the hydraulic oil as the oil is drawn off for the bar from the bottom of the tank.I thought regular chain oil would be better so fitted a separate tank to mine but in reality I have not noticed much difference in bar wear using chain oil. A bar probably last me a year so no big deal.

With a harvester bar you want them to last longer than a year at over £200 each.

But as I said I dont run a harvester bar. Current favourite is the Husqvarna X-force for £35

Sorely tempted to convert back. But first bar has lasted a few years.

Think they may have had a rather soft batch which my foray into the Harvester bar must have been from. Seen others rate them but mine wore faster than any other bar I have had. That combined with them being more prone to jam with twisty wood made me convert back.
