Hello,I'm running a small landscaping business,where
the main job is to clear brush (
like common myrtle ,kermes oak,erica/heather,ect) and
cut down small trees (like wild olive trees ,wild pear trees ,wild almond trees ,acacia species ,etc )around properties ,in order to make safety zones in case a wildfire breaks out.

The job needs lightweight and agile chainsaws.Many times ,
I literally "dive" or "climb" on fallen brush and branches in order to move forward and keep clearing the area.

Personally ,I use the Stihl MS180 as it is pretty robust ,very easy to clean and service ,it has more than the power needed for the job,while being lightweight and agile enough.

But most of all ,it has the right price !
It is used almost daily ,for seven hours per day ,six days per week .
Yes,pretty robust chainsaw ,
but with this kind of use ,it
usually lasts for couple of years.
Then they get beyond that point ,
where any attempts for further service and fixes begins to be the epitome of futility.

Anyway.
Before every new MS180 enters its
daily harsh duty ,there's a certain procedure that is followed by me almost religiously, and serves to modify the MS180,in order to live up to it's job :

1) Wrap two rolls of grippy and cushy "tennis racket handle" tape around the whole front handle of the chainsaw.

2) Lift the main jet lever ,inside the
metering side of the carburator,just a tiny bit above it's "limit" .

3) Open up muffler.
Drill extra holes or/and enlarge the existing ones and flex open the grill .

4) Install a NGK CMR6H spark plug.

5) Use the original Stihl HD air filter.Get rid of the one that comes with the saw.

6) Install an oil pump from the MS251.Now the MS180 can effectively lubricate bars and chains of over 14" length
( @ 3/8" LP 0.50 ) .That also
being the most expensive mod of all the rest.

7) Grease the choke lever case clip and case hole,as also the handle trigger and it's safety at their axle points with
silicone/PTFE grease.
I grease twice a year.Protects the
rubbing plastic parts from wear and smoothes their action by a lot .

8) Seal the opening at the case
(bar mount panel) which leads to
the oiler hose.I use a piece of hard foam ,which I press snugly inside the opening.That way wood debris can not accumulate inside the cavity and eventually push and pop the oiler hose out of its press-fit insert (towards the oil pump ,underneath the bottom side of front handle ) .

I usually run the MS180 with a
14" bar ,but there are cases that a
16" bar is used.
Bars are either Tsumura or Sugihara.

The Carlton N1C ( 3/8"lp 0.5 ) is
the preferred choice of chain.
A very durable semi-chisel one,
without any "anti-kickback" safety
features.And quite low priced ,too.

Mix oil used is the Amsoil Saber at 50:1.

Bar oil is either the Stihl SynthPlus or the OleoMac biodegradable .

Any further suggestions and or
advices are more than welcome !
 
My biggest issue with the MS180 is the air filter.Let me explain .
This saw (as well as the MS170) are specifically designed for users that almost never remove the air filter,blow it clean and reinstall it.
Thus ,by design the air filter,once it is installed it is not supposed to be removed.It is designed to be changed with a new one once a year.Otherwise ,
the penalty of frequently removing the air filter ,cleaning it and reinstalling it ,is that the filter no more fits snuggly around the oval shaped intake snorkel and wood and dust start making their way into the cylinder and piston.

Myself I frequently remove the air
filter to clean it.It's also a good way to prevent the auto
compensating carburetor to tilt
the mixture towards the lean side.

But haven't got a way to seal
the air filter around the oval shaped intake snorkel ,yet.

Has anyone found a (quick & efficient ) way to deal with that issue?
 
Well I dont know for Greece.....but my online manuals say that MS180 has BPMR7A NGK sparkplug....

Heat range comparison chart....
https://static.summitracing.com/global/images/prod/xlarge/ngk-1006_xl.jpg
there is two types of engines used in ms170 and 180
the older reg 2 cycle and parts of the world use the 2mix strato version Which uses the cmr6h plug.
I also found air filter to be an issue for heavy use-the so-called Hd version from Stihl does work better.
 
The newer 2-mix models come
with the Bosch USR4AC ,
while on their manual NGK CMR6H is the type recommended.
While ,most Stihl dealers are selling the Bosch USR7AC as the
appropriate spark plug for MS170/MS180 chainsaws.

I'm not really sure which filters you mean .Here in EU the Heavy -Duty version is a two stage one .
The snorkel side is made of white fleece material ,while the other side is made of stiff purple-grey felt material.I 've read posts about a three stage HD filter ,but nothing like that to be found on EU Stihl dealers.
 
Ya that’s the one, I think here they list it as optional replacement type
I find it doesn’t loose shape like the all white stock one And let dirt pass.
stihl Canada stopped selling Bosch plugs this year as a few come from Russia- so Ngk is the one we use mostly- never liked Bosch plugs

You are over the top with your crazy "this does this" mods. 180's are dixey cup machines when put into steady work. Get a 260....and leave it be!
 
Well I don’t know about Greece but my understanding is that in the USA market Stihl has discontinued
the ms170, ms180,& ms250. When Stihl’s inventory is depleted they will be gone. Stihl replacement is
the ms171, ms181, & ms251. I’d be curious if this is something that Stihl is doing globally!
 
There is also new ms162 and ms172 that may be coming.
ms171, 181, 251 have been out for 10 years and have never really took off or sold much in North America
 
People often scoff at the MS170/ 180 saws and think of them as expendable. I have an older 170 that I got cheap. It's the perfect ATV saw. Small, lightweight and decent power for it's size. I've used mine for clearing trails, shooting lanes and fence rows. For detailed tasks, it's the perfect scalpel instead of using a heavier saw (broadsword).

Obviously you 've never owned any MS180 chainsaw.My own experience is that they are very robust ,reliable and actually workhorses for an "homeowner" level and price.Easy to start,easy to clean and service,with spare parts everywhere,either genuine or not and easy to carry on
the most difficult ground.

Furthermore a single day wages of mine (more-or-less) matches the cost of a new MS180 ( ~250€ ).
Actually it is very cheap for me to replace a broken one with a brand new one once every two years or so and keep working.

And lastly I need a very light and agile chainsaw for my job.
The MS261 does not fall into this
category.Even the MS241 is heavy and bulky for the job.The spring AV system also is not wanted.A chainsaw with spring AV is very "wiggly",for horizontal cuts .The humble MS180 has rubber AV system which is much stiffer and offers better control when someone gets fast and furious with horizontal cuts ,moving through thick vegetation .

Here in EU the MS171 is not sold
altogether ,while the MS181 ,MS211 and MS231 are quite unpopular.
Europe's best seller of a Stihl chainsaw is the MS170/MS180.
You can still see bigger "pro" models on the workshop of a Stihl dealer ,but either those are
very old models or belong to a
professional lumberjack ( for
big trees) .
In EU we have smaller and softer trees than across the pond.
We do not need such big chainsaws,like the MS 881 or the like.
Most professionals either own a MS362 or at best case a MS462.

I totally agree!

Thanks for the very interesting post.

What would you say are the most common last-failure-before-retiring issues?

Can we have a pic of #8?

The most common failure is worn main bearing seals.
At one point air starts making its way inside the crankcase ,
while the saw operator wears
his ear protection,unable
to hear or notice early enough that the saw is screaming ,running super lean.
And bam!
New saw it is then!

As for #8 :
Here,at this particular MS180 ,
the cursed passage is blocked with a piece of transparent tubing.

Wood debris can not enter.
Otherwise,it starts accumulating moving slowly towards the oiler hose.When enough debris is accumulated ,the oiler hose pops off the case .
Actually the case has a slot,
which retains about half of the
oiler hose's "cap" .
Since the slot is parallel to the direction of
accumulating debris ,the latter pushes the hose's cap ( or "stop" if you like ) out of the case's slot .And then the hose
slightly pops off .Sometimes so
slightly ,that there is not any oil leaking.
But at the oil output
there are only bubbles present and no oil is dripping .
