50 ft
(15 m)
○ When cutting, operate engine at over 6,500/min.
Extended time of use at low rpm may wear out the
clutch prematurely.
○ Cut grass from right to left.
○ Blade thrust may occur when the spinning blade
contacts a solid object in the critical area.
A dangerous reaction may occur causing the
entire unit and operator to be thrust violently. This
reaction is called blade thrust. As a result, the
operator may lose control of the unit which may
cause serious or fatal injury. Blade thrust is more
likely to occur in areas where it is diffi cult to see
the material to be cut.
○ Wear the harness as shown in the fi gure (if so
