Blade Cutting Problems
Binding - Blades may bind in the cut if dull or
forced. Binding can damage blade, and result in
blade breakage 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 engine, and support the
trimmer or 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 directly 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.
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
MAINTENANCE
Moving parts can amputate fingers or cause severe injuries.
Keep hands, clothing and loose objects away from all openings.
Always stop engine, disconnect spark plug, and make sure all
moving parts have come to a complete stop before removing
obstructions, clearing debris, or servicing unit. Allow unit to
cool before performing service. Wear gloves to protect hands
from sharp edges and hot surfaces.
