right i'm lucky enough at the moment to have some stock of 572
xp chainsaws which was hasfana's current biggest saw in the lineup which is around the 70cc mark
i thought while we're here and just going through the specs of the 592 we put them up side by side
obviously there is around 20 cc difference in saw capacity but i thought we'd take the top cover off
just look at the key differences sort of you can see physically from the size the five nine tuning
is just that a little bit bigger there's not a huge difference in weight but obviously you
can run a far larger bar on the 90cc saw really biggest capacity on this one would be about 28
you'd be running on the 72cc saw here but we'll take the top cover off quickly of both saws so
i suppose noticeably you'll see a difference here with the covers so on the 70cc if i can get it off
it's almost glued this on right so that's your top cover on the 572 and there's the cover on
the 592 as you can see basically because there's a bigger engine you're gonna have a bigger cylinder
so you're gonna have to have a bigger cover so that's the difference in size of those the two
air filters quickly unscrew both of those same style material so that sort of felt material but
again noticeably is the air intake sizes because the 592 is going to be wanting to draw more air
to fuel the the engine then you've got a bigger intake on the 592. so that's the difference in
the air filters the other thing is spark plugs now it's been a few years since i got my hands dirty
i was a trained mechanic but basically these are bpmr7a spark plugs in the 572 which is slightly
stubbier fatter sort of plugs these are the newer sort of generation plugs here this is the cmr-6h
ngk plugs so you can see it's just slightly different noticeable difference there these
are more streamline still got your decompression valves on both and then the other big thing is
obviously your intakes so larger hole in the 592 slightly smaller on the 572 same start
stop choke assembly there as you probably already saw different exhaust systems so less restriction
in the 592. the 572 exhaust system bit like the five six d550s it's sort of a sloping exhaust
so to keep the saw more streamlined the cylinder is actually tipped back slightly so the piston is
running at a slight angle the exhaust is uh more streamlined so it just gives a a more narrower saw
basically for should we say more all-round work the 592 will be you know will be a go-to saw for
most people but it will just have that much more power that will be used for felling and a lot more
um demanding applications should we say and we'll quickly look at the clutch system while we're here
as well so i've already clutch cover off on the 592 let's quickly take it off on the 572
572 comes with the x-force um husqvarna guide bar which is a laminated bar again this runs a
3 8 chain with a c85 chain and you've got your rim sprocket again same rim sprocket three eight
by seven we've just quickly whipped this one off while we're here it's nice and clean anyway
again decent clutch system it's actually using the same clutch as the 592 but it looks like yep same
clutches so if you're running a 572 currently looks like if you had a 5 9 2 that you could
swap over clutches or anything like that if you wanted as well you quickly whip that back together
and two other things i have noticed as i've been stripping them apart is your anti-vibration system
so like i mentioned really really decent anti-vibration system on there with your captive
wire to stop the tension on the springs so there's a little update on that one
uh 572 just normal bolted system like a lot of other saws on the market and then the other
thing you have got your felling lines on the 572 vertical felling lines but on the 592 obviously
because this is going to be designed for you know bigger applications should we say you've got
horizontal feeling lines as well so it just helps you when you're cutting that notch into the tree
and you're doing your felling work where you can sort of guide your um your fell to so there you
go that's pretty much the difference to zell see more power and bigger saw so thank you ever so
