Can a person put a heavier chain on the ms170?
Yes you can! It is the same bar/chain combo on the MS211.
Bar part number: 30050004813
Chain part number: 63PM55E
Your running a .043 bar and chain, u can go with a .050 bar and chain.. wouldnt recommend though because you power to bar and chain are mediocre you put on larger, it will require more power to run the loop and there for cut slower
Sure can though dealers are instructed to tell you it can’t be done.
Some say it will void the warranty but if you spend the extra on Stihl parts you can argue the case easily provided you don’t go overboard.
Contrary to a couple of comments I’ve seen it’ll improve your saw a great deal though you’ll have to be mindful of bearing down on it, it’s just a baby after all, just take a little time & get used to its new & greatly improved character, you won’t be sorry.
See my review for details.
I keep sharpening my chain on my mini boss but it just won't go through small pieces of wood just keeps burning through on matter how sharp the chain is what am I doing wrong?
Make sure you have the correct size file for the chain and are sharpening at the proper angle. Sharpen from inside to outside of tooth using a forward motion only. I initially had the wrong size file and it wouldn't sharpen the chain at all.
Hi Rick,the problem is the rakers, those bumpy things in front of the teeth. Get a small flat file and give each one a couple strokes, file in the same direction as if sharpening. Try cutting again, there should be chips not dust. Repeat this process, until chips are achieved. The more you file, the more the chain digs in. You don't need to do this every time you sharpen your chain, only when you notice dust or the problem you have now. Good luck and may you spit chips.
Stihl makes a offset file that has a flat file and 2 round files in the tool. Ie as you sharpen the tooth the flat file also takes the rake down to proper height. If rakes are not correct, sharp cutters will not be able to penetrate wood
Hi guys, can you tell me the difference between the MS170 and the MS 171? I’m considering buying a chainsaw to cut up seasoned wood for fire wood we had felled 18mths ago.
Replaced crank seals & bearings, now having trouble reinstalling engine assembly. I'm trying not to damage the rubber manifold between carb and intake
Thanks for any help
Sorry John O, hard to describe need to be there.
On the rubber which made it slip in place. This worked for me
Have a great day
Thanks for answer
Lost first part of my answer.
Removing rubber intake tube seamed to be the only safe way. See second part of answer. Use silicone to install rubber tube and plastic ring on engine.
This worked for me.
can I use a heavier chain and bar on my ms 170? Im having trouble by braking chains [even brand new ] in hardwoods. thanks , cheers
I have never broken a chain and I cut Black Wattle, which is very hard. I suggest your chains are breaking because (a) you are over-tightening the chain tension (you should be able to turn the chain around the bar by hand) or (2) you are not getting enough lubrication to the chain (hold the bar over a rock, rev engine, and see if a fine spray of oil forms on the rock below the bar .. if not, something is wrong).
Do all the 170's leak the chain oil when not in use. I have a case to keep it in so it isn't running on the floor but am wondering if it is a common flaw?
I think all chainsaws do this. It weeps out from where lubes the chain when in use
mine doesn't, but i dont know how, as as far as i can see its a gravity feed, which means it probably should, so i can only surmise its not a problem, if all else fails, consult the dealer- sorry can't be more help.
I think all chainsaws do this unless the oil holes are blocked. A blocked oil hole may result in damage to saw parts.
Were is the bar oil ajustment on the ms 170?
There is no chain oil adjustment on this machine. It has not been a problem for me (I use canola oil). Never store your machine for more than a week or two with canola oil inside it; change the oil to a mineral oil (e.g. SAE 30) and run it for a while to get it onto the chain before storing. Drying biological oils (like canola) can dry into a resin and wreck the machine.
chainsaw will not start, have changed the fuel and have plenty of spark, however have not used it for a while, what could i do?
Gday, when I worked in the small engine repair industry we found the number one problem that came up, when a machine was stored for a while is.
1. stale fuel, as you have done that
2. check for a wasp nest in the exhaust, or a blocked exhaust screen (with oily carbon, black gunk), clean the screen by removing the single screw , then the screen, rinse in a bit of solvent and brush until clean,( just like a bit of fly screen), replace in reverse order.
3. check the spark plug is clean, no carbon build up, clean if dirty, again solvent and brush.
Now with a few pulls and it should start.
Good idea to use a quality fuel stabiliser when you store any small machine for a few months, your local mower or motorbike shop will help you out
Hope I have been of some help.
