WHILE OPERATING WITH CUTTING
BLADE
• Read and understand all safety warnings
before operating this unit.
• Always use the shoulder harness when using
the brush blade accessory.
• Keep the handle between the operator
and cutting attachment or blade at all times.
• NEVER cut with the cutting blade located
over 30 inches (76 cm) or more above the
ground level.
• Blade thrust may occur when the spinning
blade contacts an object that it does not
immediately cut. Blade thrust can be violent
enough to cause the unit and/or operator to
be propelled in any direction , and possibly
lose control of the unit. Blade thrust can
occur without warning if the blade snags,
stalls or binds. This is more likely to occur in
areas where it is difficult to see the material
being cut.
• For operation with the brush blade, do not
cut anything thicker than 1/2 inch or a violent
kickback could occur.
• Do not attempt to touch or stop the blade
when it is rotating.
• A coasting blade can cause injury while it
continues to spin after the engine is stopped
or the throttle trigger is released. Maintain
proper control until the blade has completely
stopped rotating.
• Do not run the unit at high speed when
not cutting.
• If you strike or become entangled with a
foreign object, stop the engine immediately
and check for damage. Have any damage
repaired before attempting further operations.
Do not operate unit with a bent, cracked or
dull blade. Discard blades that are bent,
warped, cracked or broken.
• Do not sharpen the cutting blade. Sharpening
the blade can cause the blade tip to break
off while in use. This can result in severe
personal injury. Replace the blade.
• Stop the engine IMMEDIATELY if you feel
excessive vibration. Vibration is a sign of
trouble. Inspect thoroughly for loose nuts,
bolts or damage before continuing. Repair
or replace affected parts as necessary.
