Abstract
A guide bar for a chain saw includes a pair of side plates and a center plate disposed therebetween. Each of the side plates includes spray holes through which a liquid can be sprayed. Liquid-conducting tubes are mounted in a longitudinal center slot of the center plate, and outlet ends of the tubes are connected to the spray holes of one of the side plates. Inlet ends of the tubes are connected to fittings mounted in a rear end of the guide bar to enable the tubes to receive liquid from a liquid source. A worn guide bar can be reversed, while still permitting the spraying to be performed. That is, while the guide bar is being reversed, the tubes are removed to enable the fittings to be reversed. Then, the inlet ends of the tubes are reconnected to the fittings, and the outlet ends of the tubes are connected to the spray holes formed in the other side plate.
