Husqvarna Rubbish Saw Not Cutting Straight... Again.

pgtrMarch 4, 2012

So after purchasing a brand new Oregon bar and chain my Husqvarna 55 Rubbish saw, in a matter of 30 minutes or so - has returned to cutting in a curvature and binding in larger diameter (oak) logs.

I realize I attempted to use it for actual wood cutting rather than the 2 in. rubbish limbs which are it's nominal limits I've accepted - call me an optimist or desperate.

I installed an Oregon 180SLGK095 PRO-LITE� Bar. I think the chain was 95VP072G.

I'm ambivalent on how good it lubricates the bar/chain. On one hand the Rubbish saw has always excelled at leaving LARGE puddles of oil anywhere it's stored. On the other hand it never seems to use up much oil during actual rubbish cutting usage. When it runs out of fuel there's always plenty of oil left. The oiling port is whistle clean.

So... any suggestions on why this saw likes to convert it's bars to curve so that it binds once it's fully buried in thicker logs? I really hesitate at throwing more money at such a piece of rubbish unless I can have a reasonable expectation or results other than the usual rubbish.

My experience over the years of cutting is that I have hit something that dulled the teeth on one side. Take a close look at the chain�s teeth and see if you see more wear or damage to the teeth on one side of the chain. A quick fix is sharpening the chain with my Sears 1984 Dermal looking sharpener (priceless). I have the 110V AC vs 12V DC and recently saw a cardless. The sharpener and Laser Tip Bars vs sprockets have saved many days of cutting dirty wood (dozed or etc). Plus, I never leave home with one saw, bar or chain (from some lessons learned) hustling free firewood. Good Luck! loger

That's a good tip - thanks.

I filed the edges of the bar and flipped it over but it still has a tendency to curve left so that leaves the chain.

I ran it w/o a bar and dribbled a lot of oil so I'm assuming that is OK.

I sharpened it before use today and try to always do the same # of strokes on each side. Nevertheless I'll take a good look per your suggestion.

Nevertheless it heats up even to the point of a little smoke coming off the blade very quickly. I'm not 'pushing' it but A) this oak is very very hard and thick (17" trunk) and B) as the cut starts 'curving' it seems to work harder as it's borderline binding...

thanks again

1. Do you have zero tension on your chain or about 1/8" of slack if you lift it off the bar?
2. Are you using a quality bar oil vs motor oil?
3. I have seen some dry petrified oak showing a few sparks but not any standing oak.
4. The term "Rubbish saw" is new to me and I c/n find a link. Are you saying it is designed just to trim?

With your efforts, you will get the job done! loger

I would guess you're not getting enough bar lubrication. You might try thinning your b&c oil with kerosene.

Does the 55 have bar oiler adjustment. 350's and up have this function where you can adjust the flow of oil to the bar? My experience with cutting crooked usually after the bar and chain get heated up dulling the teeth and cleats not sharped at the right angle. This takes some time to learn IMO. Once the angle is lost it's hard to get back. On long thin cheaper bars the bar can bend or warp causing this also. I had cheap 18" sears Poulan that done that right out of the box when I sunk it in big log. Bar was too long and flimsy for that saw especially when you hit knot.

I agree with rcmoser 100%, that sharpening a chain properly to specs is a challenge and it take good lessons and observations to learn (once the specs are loss).

1. The use of bad angles could cause the chain to try and cut too much related to power or cut curved.
2. The paid pro fixed sharpener vs Dremel or file usually gets all right each sharpening with more chain lost.
3. The dremel and file offer more quality sharpening if you learn and respect angle guides and proper stones.
4. Since going to the dermel in 84, that is all I use with a careful eye until any damage is removed vs touchups.
5. Once I sharpen a bad chain, I test it to know I got the angles correct and expect cords of cln wood from it.
6. My goal is to inspect clean and repair during my downtime at home and only any minors away from home.
7. I try to limit serious cutting to a month with or behind tree trimmers in cool weather respecting air-cooled.

The link below shows Home Depot's related ver that I got from Sears in 84 that has worked well for me.

I've used that same 18 inch oregon bar and chain combo for years on a Husqvarna 350 - never had a problem. That's cutting up to 24 inch diameter red oak.

I had a similar problem on an Echo CS400. There are 2 holes in the bar. The adjuster goes in lower one and the upper one is open to the channel in the bar. Oil was runing down the side of the bar and not getting into the channel. I cut 2 gaskets and placed them on both sides of the bar. The inside one surrounds the oiler port and the outside one covers the bar upper hole. I glued them in place on the sides opposite the bar with gasket compound so that chain tension could be adjusted without moving the gaskets. This solved the problem. I really don't know what caused the problem. Maybe I had a distorted part.

Anyone know the dimensions of the woodruff key on the Husky model 61 chain saw? (Year 1996-1997)
I would like to use an off the shelf replacement if I can find it.
Thanks in advance for your valuable time and help.
