Do you let your chainsaw run out of fuel?

[spandit]

I normally know mine is low on fuel when it stops but wondering whether I'm doing harm to it, although it lessens the risk of having stale fuel in the pipe work, I suppose.

 

I generally use it as a signal to have a bit of a rest and sharpen the chain

I'm often told you're not supposed to let them run dry but I do every fill, and my main use saw (346xp) is still going strong after 6 years.

The logic behind not running them out of fuel I think is that at the end they are sucking a lot more air than fuel so the mixture can go really weak and cause friction and overheat risking a lean seize.

Try not too , it annoys me when you hear a saw running out of fuel and the operator is trying to get that last little bit out of it for the reasons pete says.

[Stubby]

No I don't for all the reasons above .

[Mick Dempsey]

Only because it makes them difficult to start. I deliberately run the bigger ones out if I'm not going to use them for a while, for storage.

Hi

 

No I dont because as it does, it runs lean, revs increase & possibly cause damage

Yup, it will increase the risk of seizure if your saw is set a little lean or has a small airleak . doing this will lean down the mixture and the extra air or lack of fuel is what causes the saw to run a little fast on idle just before stopping.

 

If it is on a fast idle, it is relatively safe but on full bore in a deep cut with perhaps a fault as above - not worth the risk!

I will change my practice, I think, although I don't tend to use my chainsaw for long periods

I shake mine about and put on the choke just to get a little longer out them, if I don't manage to finish a cut, I feel like a failure and the saw has won!!!!!
