Customising 090 for milling

[Andy Collins]

IIRC it is possible to mod the Stihl saws with an air filter system off the Stihl Paddys motorbikes (disc cutters) to help with cleaner running? I can't find anything about this, or is it my imagination, or is it not even necessary?

How do you mean cleaner running Andy?

 

 

To stop it getting clogged with sawdust from milling?

[Andy Collins]

That's it Rob, sure I found something a time ago probably on one of the American forums, fitting an extra filter to keep more finer dust out of carb?

[Daniël Bos]

A "maxflow" filter perhaps?

i dont think there is an easy option for upgrading the 070/090 filter.

 

Saws that had a cutoff saw counterpart like the 051 and 076 its just a case of putting the high-top filter and cover on. 090 however, you would likely have to fabricate or modify a k&n style filter to fit, and i would be concerned with fitment, and knocking it off/damaging it in use.

 

I reckon a saw that was many folks weapon of choice for oldgrowth redwood felling and processing for the best part of 25yrs, should be able to handle the dust of occassional milling without too much trouble.

Ive just checked beneath the filter, and it's very negligible amount of dust beneath it. I recalled reading about this mod when I first got the mill, and just wondered if there was any mileage in it. I think you've answered my question really tree beard:thumbup1:

I shouldn't worry about a bit of dust under the filter Andy - my MS880 seems to have much more than the 090 after milling and seems to cope with it.

 

 

Things like,

 

 

• Letting the saw idle 30 secs every 4 ft down a plank
  
• Idling for a minute or 2 with gentle revving after finishing a plank
  
• Do not just switch off at the end of a plank.
  
• Don't mill the last board in a heap of sawdust - just firewood it or lift it onto something higher
  
• Regular air filter cleaning
  

 

 

The biggest thing I've found is to allow the saw time to cool and getting the air flow over the fans - not so much with your 090 as I think the older saws had more metal in and revved lower so less heat build up.

I pretty much worked that way on the Robinia, partly cos I always let saws warm up and same down anyway, thanks for the tips. Looking forward to getting my rail kit, got the 4x2's ready to go.

the yanks run big saws on a v stack with either a foam filter or k&n filter fixed with a jubilee clip...watch this clip it shows the v stack thing-e-o and how the filter fixes to it...

or are you thinking of something else...

 

ps if it runs on petrol it can be tuned!!

[Andy Collins]

Yeah I think that's what I was thinking, saw it on Arboristsite or similar a long time back
