Best way to run in a saw?

[Sam Thompson]

Hullo all

 

What do we recon is the best way to run in a shiny new cutter then? Hopefully getting my Husky 346XP from Joneses on Wednesday and haven't run in a saw before, always used someone elses!

 

 

Cheers lads

Just use it as it was intened, moden machining and materials are so good "running in" is really just a lip service thing. Being to gentle with moden engines can have a negative affect.

3/4 throttle for the first 3-4 tanks, and dont leave it ticking over for too long.....i was told to run in my 357xp when i bought it in 2003, and the sam with my 2004 ms660 but my 200t from 2006 i was told that you didnt have to bother anymore???

Let it tick over for a couple of mins..

Then full gas for the rest of it's life, 2 strokes are made to rev..

Sorry but I disagree with that. I idle and gently rev a new machine for the first tank. Treat it carefully by not revving for a long time on the second. A new machine still needs to bed in IMO and there is more friction in the working parts.

 

How can being gentle with it for the first few tanks have a negative effect?

This is what I disagreed with as others had posted in between!!

It has been proved that being to gentle or running engines in a tad rich thinking your doing the right thing prevents the internals from "lapping" in correctly and actually slowing the bedding in process.

Had loads of new saws, never had any engine problems and never run one in yet!

 

"Run it like you stole it" is a good rule of thumb.

ive always believed that giving a fresh engine some hammer, getting it loaded up asap beds the rings in a lot better. have come across several car engine rebuilds that have suffered as a result of being 'too gentle'.

 

with my new 372 and 200t, they were the first 'new' saws ive owned, and they went to work the 2nd time they were run, but that was out of necessity more than anything
