Make sure the chain is not too loose it should sag aboug 1 eight of an inch. If the chain is still slipping than you have to replace the centrifical clutch.

When go to cut engine is runnig but chain stops when touch the tree

Hi Pam:
Using chain saws takes a bit of getting used to, and it can be DANGEROUS.
- The chain must be sharp to be able to cut properly, and a sharp chain "bites" into the wood.
- Before you touch the chain into the wood, you have to speed up the engine. This takes some getting used to.
- Try this technique: With the chain about an inch above where you want to cut, squeeze the throttle about half way so the chain is spinning. Touch the chain to the wood and increase the engine speed as the chain starts to cut. The harder you cut, the more power you need to apply.
After a while it gets to be second nature.
Work Safe, and get an experienced friend to help with some "hands on" coaching.

My husqvarna 435 clutch cover came off while cutting, chain wont spin freely when re assembled

That should be all that was there. If it's a fairly new saw, it could just fit tight. Not that I recommend this, but leave the nuts 1/2 loose. I had to get my chain moving using a pair of welding gloves and pulling it around the bar. The whole thing seated properly & I finished tightening it up. the brake fits tight but you don't want to lubricate it or it won't function properly when you need it. Also be sure the brake ISN'T engaged when you reassemble and when you're finished. Hope this helps.

I have a 2004 GSF600S, when I put it on centerstand and spin the back wheel slowly. There is some regular clicking sound from the transmission / gear box section. You can actually feel the click vibration...

check the tooth profile on the drive cog and the cog on the wheel
if they are more spiky that properly formed as in a new cog
then what is happening is that the pitch of the cog has altered from wear and the pitch of the chain ( distance between link pin centers ) is no longer compatible so the chain tends to ride up on the teeth and then clicks back in place
the fix is a new chain and cogs or if the teeth are good , just a new chain

Just bought a new 455 Rancher, within 15 minutes of use the chain fell off the guide. Could not put this chain on guide again. Tried brand new chain and within 15 minutes of use, chain came off of guide...

if you loosen the nuts holding the bar on there is a tension screw on the opposite side from where the nuts are you should see it if you look from the front of the saw by the muffler you need to use it to put the proper tension on the chain if you turn it clock wise it should move the bar out tightning the chain you want a tiny bit of slack in the chain it should not be dogged down tight with the tension screw if you go counterclock wiseit should release tension. once tight tighten screws to hold on bar and spin chain by hand should be able to spin chain if not it is to tight. hope this helps

Muculloch 310 power chain saw blade will start to spin at correct speed , then begin to spin at a craw. how to correct

Remove the drive cover and wash out the clutch drum with spray carburetor cleaner. Make sure the chain is being oiled properly by running the saw at speed with the bar tip near some cardboard. It should throw off a thin line of oil after several moments. The chain should be tight enough to pull it up to the bar, but still be able to turn it by hand. Hope this helps!

Trying to assemble chain back onto bar and wheel but when I start saw the chain comes off. I feel like it is tight enough but without being too tight.

loosen clamp,back off adjustment fully,spin chain by hand[carefully] to make sure its running on bar and sprocket,,adjust tension up ,while rechecking chain alignment,then lift chain by hand at the top of the bar[the bar will also move up slightly] and adjust tension up till clearance between chain and bar is about 1/2 inch.dont let go the chain,while you lock up the clamps.then spin chain to recheck its on the sprocket properly.then try cutting wood.This procedure can apply to most chainsaws

Motor spins but chain doesn't move

If this is an electric saw, you may have a damaged gear within the gearbox, or the chain drive sprocket is spinning freely on the output shaft due a part breakage or similar. If this is a fueled saw, then wash out the clutch internals with spray carburetor cleaner and allow to dry out. Make sure that you can move the chain by hand and is being oiled properly. Hope this helps!

My chaindsaw runs but the chain will not turn it came off put it back on but it is acting like it is siezed

By runs I am assuming that when the chain is the clutch spins with the engine; if that is the case...
1. When properly adjusted you can pull the chain up off of the bar to see 1 full and two partial tooth guides.
If the chain is adjusted properly
2.Check the bar tip roller to make sure it rolls.,
If that is ok
3. Take the bar and chain off and use one tooth guide to go all the way around the bar to make sure the slot is not crimped shut somewhere.
If 2 or 3 are at fault replace the bar.
Did you know most chainsaw pro's recommend you replace the clutch outer (the sproket part) AND the bar after the 3rd chain replacement or anytime the bar or clutch are replaced for any reason. I live by it and never have trouble with the bar, chain or clutch.

If the chain is too loose on a stiga SP 510 how do you tighten it

When you give it throttle- does it rev up or bog down?

If it revs up:
Then you have a broken clutch, they are replaceable and some handy people have even repaired them in a pinch, replace it or find a handy person.

If it bogs down or dies:
:The chain brake is on (wrist guard handle forward) grasp and **** back to reset.
:The chain is installed improperly-believe it or not many people have installed their chain by inadvertently routing it over the anti-backlash bracket, reinstall properly.
:The chain is fitting to tight in bar due to lack of oiling and/or over heating you will need to replace bar.
