The chain and bar on my Stihl MS170 chainsaw has been dry as a bone. There was a lot of club oil in the container but nothing was getting provided to the pub and string. Just before I recognized what had been going on I was getting smoke while cutting down trees. Right after that the string locked strong on the bar. I removed the club and string and cleansed out the openings and locations where the essential oil should be coming from. That didn'capital t work - no essential oil output actually with the chain and pub removed and the engine operating. I left the chainsaw with a small motor repair outfit and after functioning on it for some period the specialist stated he got no luck possibly and he also checked with the seller who said I will probably need the oil pump changed or fixed and he mentioned a specific tool is required to do that - repair expenses most likely over $100!

I acquired a sales brochure on hand with a exclusive deal on the exact same chainsaw - but before rushing out to obtain a fresh one particular I made the decision to take a break at repairing the saw myself. The technique I used proved helpful and the movie and ways below show how I obtained the oil flowing again. Unscrew the pub oil container cap and totally eliminate the cover and the keeping clip. Create certain there is definitely some pub essential oil in the tank. Find an adapter for your shop vac that will create a realistic seal with the bar oil input spout. I had an old Electrolux vacuum cleaner cleaner line that occurred to match the store vac hose on one finish, and the insight spout of the essential oil tank on the additional finish.

Assess the oil output of the chain saw bar oiler to determine whether or not adjustment is necessary. Allow the chain saw to run for 2 to 3 minutes to warm up.

But whatever you can find to create a fair seal will perform. Duct video tape might function ok for instance.

The link need not really be ideal (quarry wasn't) but a fair quantity of stress must end up being created in the container for this to work. Before blowing into the container change the vacuum cleaner ON and whack any dust or grime out of the vacuum hose(h) in any other case you could contaminate the oil that's in the container and exasperate the problem. Before pressurizing the tank double check out you possess the hose connected to the result of the store vac normally you will be slurping up bar essential oil from the tank and into the shop vac. Create a firm connection between the vacuum line/connector and the oil tank input spout. Convert the shop vacuum ON while firmly keeping the connector to the container spout. Maintain the pressure link for a acceptable period - I waited 30 plus mere seconds.

• Assess the oil output of the chain saw bar oiler to determine whether or not adjustment is necessary. Allow the chain saw to run for 2 to 3 minutes to warm up.

But the period needed will likely vary from situation to situation. Don't anticipate to find essential oil oozing from the bar/chain output slot (I didn't observe any until I started the engine up), but if you notice essential oil that would end up being a great indication.

Replace the oil tank cover. Begin the engine up in the usual way with the pub and chain still away. Check to discover if oil is oozing from the oil output slot.

If no essential oil is noticeable after working the motor for a few seconds replicate the pressurizing process (I experienced to do it again it as soon as). Once oil is usually flowing reinstall the pub and string and run another oil test - this time keep the end of the club near a piece of cardboard boxes to notice if you get any oil splatter on the cardboard boxes (with the motor operating). I do this test but got extremely little spatter and thought that I might have a issue (some other references indicated that this test can end up being a useful indicator of obtaining enough essential oil to the chain). If all is definitely okay to this stage it's period to perform a true world test. Also though I didn't get much essential oil splatter on the cardboard I went forward and gave the saw a check by slicing down a number of small trees and branches. I held at this for at least a fifty percent hr without any apparent troubles.

A visual check right after cutting pointed out that there was light oil/sawdust remains on the club and that has been a true good sign. I later taken out the pub/chain cover up and found that there is usually plenty of oil being distributed as pointed out in the photograph in this step. Bottom range - the method proved helpful and I kept myself a few of hundred bucks! Try working stihl club essential oil it will work much better furthermore there are usually no specialty tools required to get rid of that cylinder.

It merely sits under the clutch any repair store with an educated technology should become able to manage that mm socket fixed and a t27 a smooth had mess motorist and a chain is all that can be needed oh and a spark plug socket and probably needle nasal area pliers is definitely all that is certainly needed to remove the essential oil tube. But much better yet simply take it to where ever you bought it because in purchase to sell stihl you must become a provider center hence no big box stores have stihl.

I perform some work that demands a chain saw. Someone offered me a McCuIlough Mighty-Mac (l believe that is usually the model, at minimum XXX-Mac), 16' bar, several yrs ago. I knew it wasn't much of a found, but I have got used it numerous times, and provides served me quite properly for my restricted needs. Last night, I reduce down some badly overgrown yew shrubbery and hauled away the particles (bonus work for this period of the year!). In the morning, it ran pretty well, began with a little difficulty.

But, in the mid-day, it would begin Alright when frosty, but I had great difficulty obtaining it began when comfortable (elizabeth.g. After refueling, or after launching particles for hauling). I used it for a job last Fall, and had similar troubles. Having out the spark plug, cleansing with cable clean, and reinstalling, usually helps sufficiently to get it started, albeit challenging. I set up a fresh plug final Fall near the end of the project, saw improvement, and I experienced the issue had long been solved.

Right now, I believe the problem can be beyond the put. I have got not really tinkered mechanically with chain saws. I have got examined and cleaned the surroundings filtration system. I possess covered by insurance the choke works properly. Also, I examined exhaust slots and discovered them obvious.

The one issue I'm questioning is definitely the primer light bulb functioning properly. Nevertheless, I understand that it must become operating when the motor is frosty. For various other engines, make use of of the primer for cozy start is not essential.

But, I possess attempted it on this string saw as a supplementary tactic, not really as a issue of program. The other item leading to the issue might become a coil. Like I said earlier, I've not really tinkered very much with this machine, so I put on't know 'what'beds under the hood.' I put on't even know where to discover the coils on this engine.

Any suggestions on a great place to start troubleshooting? Wear't suggest purchasing a brand-new chain saw. I'meters too near to being lured, but my use is so restricted I possess a tough time spending $300 or therefore for a great Stihl noticed.

One issue, is certainly you're making use of a saw thát if its what l'meters considering it is definitely, is definitely around 20 yrs older, and you require to purchase something much newer like a modern Stihl or sométhing like that. Thé Apple computers of the small mac, which is probably what you've got, are VERY complicated saws. There is usually no awesome mac that I know of, unless its a later on model made of all plastic material. The mini mac is definitely a little tophandle noticed, able of pulling 18' bars, at least the types I've used could. The mini apple computers, if they develop problems, just toss em, dont trouble to fix it trigger you'll get so discouraged attempting to draw the engine out of the situation to actually achieve the carb to repair anything in em. The best program of actions, would become toss that factor, get yourself a Stihl MS250, or something comparable like a husqvarna 300 collection noticed. I wouldn simply throw, it but i dont know anything at aIl about that particular found.

I think one of thé probles with aré culture is definitely that it is throw away. Items to examine would be the coils like you said, cleaning the vehicle(diapraghm may become poor?) or even the head gasket may be poor.

If you actually are at a reduction of how to repair it ou may possess a nearby repair store with numerous years experiance and perhaps some left over outdated components who i wager would gove you some advice. And if you believe purchasing a new saw is the only way then i would recomend at least trying to fix this one, most severe case you cant obtain it back again tpgether and running but at least you discovered something about how it works for te potential. I wouldn just get rid of, it but i dont know anything at aIl about that particular found. I think one of thé probles with aré culture is definitely that it will be throw apart. Points to verify would become the coil like you stated, cleaning the vehicle(diapraghm may be bad?) or also the head gasket may be bad. If you actually are usually at a loss of how to fix it ou may have got a regional repair store with several yrs experiance and possibly some still left over old components who i bet would gove you some advice. And if you think buying a brand-new saw is usually the just way then i would recomend at least trying to fix this one, most severe situation you cant obtain it back again tpgether and working but at minimum you discovered something about how it works for te future.

Theres just ONE type of Mac pc I'd ever use, the Aged ones, strong magnesium throughout the device, 99.9% of it is definitely made of that things, and they're also HEAVY. Those types, you just cant get rid of, the newer types made of plastic material, ignore it they're mainly because great as a walmart special poulan. Its oné of those sáws you just dont repair, trigger once you repair the 1st problem, 3-10 more pop up. At least the old all magnesium types were reliable as gravity although large as prospect. This is definitely personal encounter I'michael speakin from too, I've got 2 of those previous magnesium Apple computers, a 10-10Auto, and an older 250, both run great, simply cant get rid of either one óf em, and l've become tryin for awhile. They've obtained what seems like a 10k hour life expectancy on them before you possess to ré-ring em, ánd then you're good to proceed for another 10k.
