Remove the packed dirt and debris from the blade.
•
greater depths until the desired depth is obtained.
• Edging can be customized by varying the number of
passes and the distance between the blade and the edge
of sidewalk, driveway, or curb.
HIGH ALTITUDE OPERATION
If operating equipment with engines regularly at
altitudes over
5,000 feet, the carburetor’s air-fuel
mixture will be too rich and emmissions may increase.
On engines not built for the United States the
carburetor can be adjusted to operate under this
condition. The carburetor should be returned to its
normal setting if regular operation is less than 5,000
feet. Contact your service center to modify the
carburetor.
