2015 Ms181 Non Start - at my wits end!

Talking yourself out of work Steve.

The thing is, I don't need it, looking at taking it easy after the last few months I have had!

So whipping the covers off and cleaning the covers and engine, cleaning the outside of the saw, checking the sprocket rim, making sure the tank is clear of chip, the chain brake works and that nothing is falling off isn't worthwhile? I get fed up with getting saws in that are shagged, knackered, unloved and generally buggered with the owner thinking all it needs is a port job and this will make up for 5 years lack of maintenance.

I think some owners should wake up and realise that these tools make their living and a little TLC is needed on a regular basis! 

Mate, I totally get preventative maintenance and only today I changed the micro oil at bang on 150 hours. But if a chain brake fails it’s down to one of three components, and no preventative maintenance will prevent it, short of replacing them all prematurely. 

 

I replace all wear components (bar, sprocket) as required. Only change air filters on strimmers (grass blocks them) and i can’t remember the last time I changed a fuel filter on a two stroke machine.

Glad it is sorted, we are always interested in what the issue ended up being just to double check how good we actually are. Carb issues make up around 75% of the issues saws tend to have when not running or running badly.

Yeah, someone did say on page 1 to just put a carb kit in it, dunno who that was ??

I would blow both tanks out once a month, grease my sprocket bearing weekly. Change plug 6months. Clean saw thoroughly every month. Change fuel filter every 6months. My saws seem to run fr yrs Oddly. K

Whilst i know you are probably correct,

Snigger, change fuel filter? I think i may have blown one out every once in a while but probably never changed one. Air filters, sure, greasing sure, sprockets, dressing bars, compressed air on saw yesh.

Good on you though, i probably ought to change them

Er - most MS200s that come in to me have a chain brake so full of shyte that slows down the action, can break the return spring and eventually causes the brake band to rub on the drum, especially if the bands seats are also soiled.

The brake band can be checked for wear before it breaks. If it is typically under 0.75mm thickness when originally 1mm thick, it needs replacing.

Wear in various components can be found by actuating the brake from the right side nearest the drum and then on the extreme end of the brake guard to make sure it actuates as it should. Makita 7900s had an issue with this as do some MS201s and others.

You can of course leave it and only find out it is shagged when it hits you on the head up a tree

Sorry, I don't mean to get at you but I just hate safety devices not being looked after especially brakes and chain catchers....nothing personal but just putting things right as they should be for the record!

I think that not only preventative maintenance should be carried out, but also general housekeeping of your tools i.e actually cleaning and blowing your tackle off (with compressed air! [emoji6][emoji16]) helps massively as no build ups of shite can progress to aid the wear that occurs as mentioned above.

Might be worth having the carb sonic cleaned as well.

Those hedgehogs do a good job .

Most carbs don't need US cleaning but the ones that still play up after a GOOD overhaul can often be cured with a good boil in a US tank.
