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 J-handle between the operator and cutting
attachment or blade at all times.
NEVER cut when the cutting blade is 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 propel the unit
and/or operator in any direction, possibly causing a
loss of control. 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.
Mix and add fuel in a clean, well-ventilated outdoor area
where there are no sparks or flames. Slowly remove the
fuel cap only after stopping engine. Do not smoke while
fueling or mixing fuel. Wipe up any spilled fuel from the
unit immediately. Always wipe unit dry before using.
Move the unit at least 30 feet (9.1 m) from the fueling
source and site before starting the engine. Do not
smoke or allow sparks and open flames near the area
while adding fuel or operating the unit.
