To put a chain on a chainsaw, first make sure the saw is turned off and the chain brake is engaged. Then, loosen the chain tensioning screw and place the chain over the guide bar, ensuring it is facing the correct direction. Adjust the tension of the chain by tightening the tensioning screw until the chain is snug on the guide bar. Finally, release the chain brake and test the chain's tension by pulling it lightly.
