Chainsaw is clogged
Chainsaws generate a considerable amount of heat during operation. Air ventilating in and around the saw during operation allows the heat to escape.
Not enough oil
Another reason for smoking could be that the chain bar is overheating. During operation, the chain runs across the bar with the resulting friction generating heat in the chain and bar.
Chain tension too tight
You may have tightened the chain too much, causing friction. Three main factors influence the amount of friction. First is how smooth the surfaces are. The second is the speed at which the surfaces interact. The third is the amount of pressure between the surfaces.
Old fuel in the tank
If your chainsaw is not overheating but is still smoking, the problem could be with the fuel. Gas chainsaws burn fuel to operate. Incomplete combustion causes smoke.
