391 came out in 2010

9t .325

:thumbup:So which chain and how low the rakers ?

They have a warehouse at Cothill,Plympton for ebay and internet sales.

At Exeter St,Plymouth they have some popular units on the shelf and repair the older stuff , that can't be exchanged.

Passive infer red sensors with manual override.

Buy separate sensors and install low down across access points.

install flood lights high up looking down so they cover more yard and don't dazzle.

Anybody know how to disable the limiter? Have been felling on the highways tonight, ringing up an ash.

 

It took a few minutes for the autotune to get its crap together. Goes like stink! But under 10" and the limiter kicks in (14.2k rpm), after that it drops to a manageable speed, about 15-18" and it drops to the usual 8-12k rpm. Not much fun having logs catapulted towards you though! I'm surprised how strong it runs, as I was quite conservative with the porting compared to the Americans, but I suppose that's because they're running 28". At least the autotune means I don't have to piss around with a tach!

You're not working it hard enough.

Bigger sprocket and lower rakers .

Which chain and sprocket are you running ?

15" top of bar,15" under the bar and 12"around the bar mount and sprocket = 42"

so 28 full chains from a 100 foot roll or £11.39 a chain.

Some where I've seen a list of species not to be planted under powerlines - Ash,etc

I was going to buy a Stihl 390 in 2010 but dealer had sold out.

Bought 365 special instead, because had better power/weight than 391.

Good decision , its been faultless.

The Husky 365 and Stihl 390 were comparable farm/fire wood saws.

Surely a 391 can manage more than a 16" bar.

The 365 xt will run 20" in hard and 24" in softwood.

some one must really need logs at biding 250 for this on ebay, and having to process it.

Bargain - Tom from Chudleigh has put them on Gumtree for £400

Nice on a 20", but have run it with a 28" but not very exciting, but needs must at the time.

Get some skip

Fairy lights I think

Where's that spec savers free appointment voucher

There is one in the tractor back end you can make use of:thumbup1:

Post 5 line 6

O.K I've whipped mine off.

Total length 135mm,126mm of coils.

You won't get more output by using 2 of the tractors spool valves.

Sounds like the winch will need to be connected to power beyond to get the flow you require.

A PTO pump requires a reservoir and 150-200 litres of oil so is not a cheap option.It may also prevent you from attaching what you want to the rear e.g 3 point linkage.

The threads on a 5 litre " cube " are different to the stihl auto shut off spouts.

I refill 5 litre oil " cubes " from 20/25 litre containers.

The pull up spouts soon split , so I would be interested to know if anything else fitted.

Is that copper wire nailed to the Ash (my guess) tree ?

Sounds like you only need CS30 (Maintenance + crosscut) without assessment.

CS31 is fell small tree.

Should only be 1 or 2 days and £200 ish.

The 40 and 45 share every thing but pot and piston.

My 40 has a 3 clutch shoes and spring is about 150mm fitted but not engaged.

part number 504 21 00-16 according to my parts pdf.

120mm would mean about 25% stretch - looks about right but could be a pig to fit.

And a wife beater.

I got one I would like to have a go at loving!

You haven't been coveting her ass Pete ?

A Stihl spout on a normal 5l can works for me. Can't stand having the petrol and oil in the same cumbersome package. Combi cans were designed for loggers to make it easy to carry oil, petrol and basic tools for a long walk into the woods. Beats me why arb guys use them?

My thaughts exactly.

Don't need chain oil for hedge trimming and strimming etc

Decant chain oil into used 5 litre can.

You would buy it because it was one of the more affordable 3/8 chain available at the time. Since you would be grinding on it, you wouldn't bother starting with square chisel. RS is out, the teeth stand shorter than it does on Oregon chain. Oregon chain, with the taller teeth, have more chip clearance.

 

In any case, that was to show you the basics of how to make a chain faster. I would assume most would get the idea.

I accept your point about LP being taller than RS - its very noticeable if you put them side by side and explains why Stihl recommend a smaller (5.2mm) file for 3/8 chain.

However LP and LG are both round ground chisel and it must be difficult to grind the LP's drivelink down with the raker in the way.

You remove the corner of the tail. It helps make the chain smoother as well.

Why start with LP chain and grind the bumps off the drivelinks ?

Wouldn't your start with LG or RS ?
