the operator or others.
S WHEN BLADE THRUST OCCURS --
Blade Thrust can o ccur 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. By
using the unit properly, the occurrence of
blade thr ust will be reduced and the
operator will be less likely to lose control.
S Cut only grass, weeds, and woody brush up
to 1 cm i n diameter with the weed blade. Do
not let the blade contact material it cannot cut
such as stumps, rocks, fences, m etal, etc., or
clusters of hard, woody brush having a
diameter greater than 1 cm.
S Keep the blade sharp. A dull blade is more
likely to snag and thrust.
S Cut only at full throttle. The blade will have
maximumcutting powerand is less likely to
bind or stall.
S “Feed” the blade deliberately and not too
rapidly.Theblade canthrust a way ifit isfed
