What causes the chain to cut improperly?
Several things may contribute to why your chain is not cutting properly. If this is the first use of the saw and it appears that the chain is burning the wood, it is likely that the chain has been put on backward. If the saw has cut fine in the past, but now is having problems, it is likely that you have dulled your chain. This can easily happen when you hit dirt with your saw or after several hours of normal operation. Is your saw cutting crooked? First, check the cutters on the chain and the guide bar rails. If one side of the cutters is sharper than the others, the sharper side will cut into the wood deeper. If the rails on the guide bar are uneven, the chain will ride deeper on one side and will cut crooked. Is the engine running, but your chain is not turning? First, you should check the drive links on the chain, the bar grooves or the sprocket nose on the bar. A burr on the drive links will bind the chain in the bar. If the bar has been pinched, the chain will not pass freely thr
