New MS391 not oiling chain!

[Mesterh]

Take some pictures of the bar, chain and the crank case where the bar mounts.

 

Otherwise give up.

I think it might be that honey-like Makita oil to blame.

 

From an Amazon review:

 

"Well, it is chainsaw oil, not much to discuss. It does its job, and it sticky and dense so it does not fling off easily. That said, it turned out to be a little too sticky for the auto oiling system of my Worx electric chainsaw. There was too little oil being dispensed through the oiler. Adding a little thinner to the oil fixed the issue."

 

Bingo.. Maybe?

 

 

Some oils are thicker than others, I find Oregon or similar perfect, Stihl oil is like piss, far too thin and runs out very fast. Not familiar with makita oil, but using the word honey suggests it's far too thick, drain the oil, swill with petrol and try a different, thinner oil

If the oil is too thick surely it wouldn't be leaking badly. Thinner oil will leak worse I would think.

Makes me wonder if there is a small crack or split somewhere that only lets oil out when the bar is in place and causing a restriction but when removed, the oil freely comes out of the right place.

 

How difficult can this be:001_rolleyes:

 

Possibly, let's see if we need to explore that avenue. Thanks mate.

 

Yes full house

 

That Makita oil is quite thick mix it with some cheap sae 30

Or a better idea have another red saw to eat that oil up :thumbup:

Seriously I hope you've cracked it now

 

Exactly what I'll be doing tomorrow! (well the sae30 bit lol)

This will prove nothing, other than that I have a bar, a chain (now scorched) and a crank case, which I've meticulously cleaned like a new pin all afternoon to my girlfriends delight.

Stihl oil is like piss, being the key phrase here. Their pumps, channels and bars are all designed to pump and distribute piss, not honey.

 

We might be onto a winner here, thanks!

If it's too thick it won't be able to enter the bar at all via the pin prick diddy hole on the Stihl bar is my reckoning.

 

Like trying to spread marmite over a cheese grater rather than dousing it in washing up liquid.

 

Yes that's how my mind works

I found this unopened container in the garage, seems a lot 'juicier' than the Makita crap

 

 

 

Saw emptied of honey and filled with nectar.

 

When the sun rises, the saw will have its rebirth.

Oh Lord:laola:

Remind me not to have breakfast at your house then

Lol, you won't have to clean your teeth afterwards though!

My turn now. First job, assuming its a 20 inch bar , check the bar model number on the side of the bar, for a 20 inch it should be 3003 008 6121, if its 18 inch then its 3003 008 6117 and if its 16 inch its 3003 008 6113. If the last set of 4 numbers start 52 then its the wrong bar and thats your problem. bar oil hole does not line up. The MS391 uses a different bar to the MS361 but will accept the same chain.

Most plastic chassis saws have a vent hole in the oil tank along side exhaust and if the plug in vent is loose or missing oil is pump out there instead of onto chain. A self tapping screw usually fixes. Plug is not available as a seperate part.

In terms of warranty I dont think warranty is transferable, as technically you have bought it as a second hand saw

Update:

 

After a busy day at work and getting home late, bursting to try it out, I ventured out into the back with the saw, filled with Oregon oil and a splash of diesel to clear out the goopy Makita crap.

 

Took a panel of cardboard out and laid it down, revved the saw up and started oil painting like Picasso

 

After laying a dozen or so good oil stripes I whipped it through a bit of old wood I had lying around (little branches, nothing too hard ) and it cut with venom.

 

Then killed the engine and inspected it.

 

Chain looking dark and shiny, rather than brown, blue, burnt and dry? check

 

Chain, bar, bar nuts and side case all cool to the touch?

check

 

Happy Turtlewoods? :thumbup: checkamungous !!
