Sharpening Metal Blades

Several styles of metal blades are approved for use on the Brush Cutter.
The 8-tooth blade can be sharpened during normal maintenance. The
clearing blade and 80-tooth blade require professional service.
Before sharpening, CLOSELY
inspect blade for cracks (look at the
bottom of each tooth and the center
mounting hole closely), missing
teeth and bending. If ANY of these
problems are discovered, replace
the blade.
When sharpening a blade, always
remove the same amount of
materials from each tooth to
maintain balance. A blade that is not
balanced will cause unsafe handling
due to vibration and can result in
blade failure.
1. File each tooth at a 30° angle a
specific number of times, e.g.,
four strokes per tooth. Work
your way around the blade until
all teeth are sharp.
2. DO NOT file the 'gullet' (radius)
of the tooth with the flat file. The
radius must remain. A sharp
corner will lead to a crack and
blade failure.
