To replace the chain on this purner, please do the following:
First, loosen the sprocket nuts with the wrench and remove the cover. Put the new chain on the guide bar with the cutting teeth facing forward. Then place the chain around the sprocket and fit the guide bar onto the mounting studs. Reinstall the cover, making sure the tension pin fits into the guide bar. Finger-tighten the nuts. Tighten the chain until it is snug but still moves easily by hand. Hold the tip of the guide bar up and tighten the sprocket nuts fully.
