Breaking in a new saw

[keptenjim]

What's the general feeling about new saw break in period? The manual says "do not use full throttle off load for 3 tank fillings" So full throttle is OK as long as you're cutting wood? Doesn't sound very precise - maybe I'm a bit over cautious in view of the cost of new saws

This afternoon picked up new 880, tomorrow morning 5' diameter Beech stem to ring up and it's been down 4 years If the middle's any good i'll mill it too:blushing:

 

HP Super in all saws and anal about mixing and fresh fuel.

 

Regards,

Rev it hard for short periods, it is the build up if excessive heat that should be avoided.

 

You basically want the piston and ring to wear in on the freshly honed bore whilst it is new and rough.

 

Running it in slow will glaze the bore and stop this happening.

 

Flat out in the cut for short periods.

I've heard and tried various things over the years. Run through a full tank of fuel on tick over, auto tune saws want burying in big wood full tilt, gentle use for the first few tanks etc. Nothing seems definitive to me, I haven't yet (touch wood) killed a new saw. Currently running in a new 550xp, it had a few tanks of two stroke through on demo then I've switched to aspen. I've run about 7/8 tanks through and it's loosening up and flying.

 

I reckon spud is the man to look to for anything with an engine

How long would you do this for spud?

4-5' diameter 18' long down 4 years but kept off the ground...

 

Hoping the spalting's gone through but not turned to pulp, last one was soft in a lot of places.
