Makita DCS520 doesn't cut

If you have a 325 chain on a 3/8 bar I would imagine alot of friction. Your clutch may be or may have been ok.

Hi Ben got your e-mail and I'll copy this post to it.

 

 

First off no bars last for ever - they are disposable like a chain.... same as a chainsaw file (ob relatively you go through loads more files relative to bars) you can use a bar for a long long time but over time the bar groove gets widened by the passage of chain down it.

 

 

How long does a bar last? - difficult to answer indeed as depends on a multitude of factors - use, chain and chainsaw maintenance, has the chain come off the bar, burred the drive links, is it milling, etc the list goes on.

 

 

The oregon selector guide gives a K095 mount - which is good as it is the main mid range Husky mount.

 

 

Rather than go into what the pitch and guage is etc have a look here Chain | bar | sprocket identification and try and take the time to get to know what all the numbers mean... don't worry so much about the Makita numbers on the bar... most bars get replaced with oregon, (or can be cannon or sugihara...) I expect oregon probably make the Makita bars anyway.

 

 

So for you saw you can 'pretend' on the selector guide here to have a Husqvarna 160 - 18" and it will give you the results and these bars will fit your saw.

 

 

.375 is used on the website instead of 3/8 the / sign causes problems.... but 3 divided by 8 is .375...

 

 

Get a new chain with a new bar - micro chisel is prob best for you use. If on my site use Husqvarna 160 in the chain selector.

 

Sign up first as you get 10% discount being an arbtalker - e-mail me when you have signed up for me to set this. Also check your sprocket - is it a rim or spur? Hopefully a rim so you can just change this as I expect it's worn... if a spur then that will be harder as oregon don't seem to list one! Sprocket care

Be damn sure this is correct - I have seen 3/8 on a 0.325 sprocket before - it was gruesome and didn't do the saw a lot of good - you should be able to pull the chain around the bar in both directions easily and with little resistance all being well!

 

Check the sprocket type, the chain pitch and the bar pitch, if the bar is 3/8" then the chain and sprocket should also be 3/8th.

. Get yourself a set of vernier calipers to check the length of your cutters when you sharpen.... let me know if I'm talking nonsense chaps.

I know what you mean but cutter length is crucial to smooth cutting, stay sharp of the chain, speed... everything really... hence why guides are so good as they get cutter length the same for you.

I am well aware how short my life is. They are handy to have especially if you have to file back quite a bit. A rainy day spent sharpening chains and measuring cutters is a nice day pottering for me. I wouldn't advocate taking them out in the field, that would be mental.

A fencing staple can be used if you squeze the points to the correct lenght.

I had the exact same problem on my Makita, put on new bar and chain but still carried on cutting to the side and jamming the chain. turned out the aluminium cover thingy that covers the chain brake mechanism had bent and was pushing the chain out sideways.
