The light 04 is the first Stihl guide bar model to feature this new name and innovative design. The new light 04 features a special construction that means you benefit from improved balance and therefore less fatigue when sawing, because this tool's slim contour means it weighs up to 200 g less than existing guide bars. The result is easier maneuverability during cutting and agile chain saw work. And the new design is more than just easy on the eye, as you can also read information about its properties and features directly on the bar. So you can always find the right combination of bar and chain for your Stihl chain saw.
