OPERATING INSTRUCTIONS FOR
USE WITH WEED BLADE
S BladeThrust is a reactionthat only occurs
whenusingabladedunit.This reactioncan
cause serious injury such as amputation.

S WHAT CAUSESBLADETHRUST -- Blade
Thrust canoccur whenthe spinningblade

contactcausesthebladetostopforaninstant

operator or others.
S WHEN BLADE THRUST OCCURS --
Blade thrust can occur without warning if
the blade snags, stalls, or binds. This is
morelikely tooccurinareas whereitis diffi-
cult to see the material beingcut. By using
the unit properly, the occurrence of blade
thrust will be reduced andthe operatorwill
be less likely to lose control.
S Cutonlygrass,weeds,andwoody brushup
to1/2inch indiameter withthe weedblade.
Do notlet theblade contactmaterial itcan-
not cut such as stumps, rocks, fences,
metal,etc.,orclustersofhard,woodybrush
having a diameter greater than 1/2 inch.
