Blade Applications
Use blades only in recommended applications.
Grass/Weed Blade - Use Grass/Weed blades for
cutting thick grasses, weeds, light to medium veg-
etation, and thick-stalked growth such as reeds and
palm grass.
Brush Blades - Use Brush blades for cutting dried
brush, small saplings, and large weeds with thick
stalks.
Clearing Blades - Use Clearing Blades to cut
saplings, small trees, and thick, heavy brush.
Blade Cutting Problems
Binding - Blades may bind in the cut if dull or forced.
Binding can damage blade, and result in blade break-
age or injury from fragments and flying debris. If a blade
binds in a cut, don’t try to get it out by applying “up and
down” force to pry the cut open. Applying prying force
to the blade can bend the blade, and result in blade
failure and injury.
To free a blade that is bound in the cut, stop the en-
gine, and support the trimmer/brushcutter to keep
stress off the blade. Push the tree away from the entry
point of the cut to open the cut, and pull the blade di-
rectly away from the cut in a straight-line motion. Use
caution when releasing the tree to avoid being struck by
spring-back or falling.
Inspect the blade for damage before proceeding.
Sharpen teeth if dull, or replace blade if cracked, bent,
missing teeth, or otherwise damaged. (See "Blade
Sharpening," on next page for important sharpening
information
To prevent binding:
Keep blades sharp
Avoid excessive pressure during cuts
Don’t exceed cutting capacity of blade
Don’t use blades with damaged or missing cutting
teeth
Don’t rock blades in cut
