Saw chains, stretch?

Rule of thumb, NEVER put a chain back on a chainsaw that has been thrown off.its very dangerous and destructive. It ruines the drive teeth and put back on will ruin the drive sprocket and bar. The chain is the cheapest part and is first to go and can do the most damage. Spend the money, it will save you a bunch

my chainsaw runs great sounds great but it doesn't run the chain i have no idea how to fix it please help.


Assuming you have dis-engaged the chain brake then the chain drive behind the clutch, chain drive teeth (below the cutter teeth, and the chain bar end teeth all have to work together. If, say, the chain has a pitch of .325 but the bar and / or drive are 3/8th then the chain won't work. With the little knowledge you have I suggest you take the saw to a dealer.

How tight should chain be on chainsaw


The chain should fit snuggly at all points of the guide bar, as a rule of thumb you should be able to lift the chain on top of the bar to exspose three inner drive links, with a gloved hand the chain should pull readily around the bar ( with the engine stopped )

. TAKE THE COVER OFF AND YOU WILL SE THE SPROCKET THAT THE CHAIN DRIVES FROM LOOSEN THE SCREW THAT TIGHTENS THE BLADE, IT SHOULD LOOK LIKE A PEG, IT GOES INTO THE BLADE TO INSTALL CHAIN THE SHARP SIDE OF THE TEETH MUST BE POINTED DOWN ON THE TIP OF THE BLADE, REINSTALL SPROCKET COVER AN TIGHTEN BOLTS HAND TIGHT(MAKE SURE PEG IS IN HOLE OF BLADE)TIGHTEN THE SCREW TO ADJUST CHAIN TENSION , CHAIN SHOULD BE PULLED UP FROM CENTER OF THE BAR TO PREVAIL HALF THE CHAINS LOWER TEETH WHEN PULLED UP. NOW TIGHTEN UP THE NUTS THAT HOLD THE COVER, BUT NOT SCREAMING TIGHT. MAKE SURE TO OIL THE CHAIN WITH BAR OIL.. YOU MIGHT NEED TO DO THIS MANLY IF YOU DON'T SEE A SPRAY OF OIL COMING OFF TIP OF THE BAR WHEN HELD NEXT TO A PIECE OF WOOD WITH THE SAW RUNNING AT A HIGH SPEED ...BE CAREFUL !!! PLEASE , TAKE YOUR TIME, HAVE A GOOD FOOTING WHEN USING A CHAINSAW ! THERE ARE A ON A DANGER SCALE OF 1-10 THERE A SOLID 19 ! JAY..

My chainsaw starts when there is no bar and chain on it but when I put the bar chain and side casing back on tighten the chain and pull the starter cord it is hard to pull and then the chain goes loose again


Have you just replaced the chain?
If so there is a possibility the chain and drive sprocket don't match causing the engaging spurs to ride on the sprocket teeth
