Sharpening Metal Blades
Several styles of metal blades are
approved for use on the
Brushcutter. 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.
If an electric grinder is used, use care not to overheat teeth, do not
allow tips/tooth to glow red or turn blue. DO NOT place blade in
cooling water. This will change the temper of the blade and could
result in blade failure.
