WHAT CAUSES BLADE THRUST Blade
Thrust can occur when the spinning blade
contacts an object that it does not cut. This
contact causes the bladeto stop for aninstant
and then suddenly move or “thrust” awayfrom
the object that washit. The “thrusting” reaction
can be violent enoughtocause the operatorto
be propelled in any direction and lose control
of the unit. The uncontrolled uni t can cause
seriousinjuryiftheblade contacts theoperator
or others.
S
WHEN BLADE THRUST OCCURS. 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. By using the unit prop-
erly, the oc currence o f blade thrust will be
reduced and the operator will be less likely
to lose control.
S
Cut only grass, weeds, and woody brush up
to 2 inches i ndiameter with the brush blade.
Do not let the blade contact material it can-
not cut such as stumps, rocks, fences,
metal, etc., orclusters of hard, woody brush
having a diameter greater than 2 inches.
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
maximum cutting power and is less likely to
bind or stall.
S
“Feed” the blade deliberately and not t oo
rapidly. The blade can thrust away if it is fed
too rapidly.
S
Cut only from your right to your left. Swing-
ing the unit in the same direction as the
blade spins increases the cutting action.
S
Use the shoulder strap and keep a firm grip
on the unit with both hands. A properly ad-
justed shoulder strap w ill support the weight
of the unit, freeing your arms and hands to
control and guide the cutting motion.
S
Keep feet comfortably spread apart and
braced for a possible sudden, rapid thrust of
unit. Do not over r each. Keep firm footing and
balance.
S
Keep blade below waist level; it will be eas-
ier to maintain control of unit.
S
Do not raise the engine above your waist as
the blade can come dangerously close to
your body.
S
Do not swing unit with such force that you
are in danger of losing your balance.
Bring the engine to cutting speed before enter-
ing the material to be cut.
If the blade does not turn when you squeeze
the throttle trigger, make sure tube is fully in-
serted into the engine.
Always release the throttle trigger and allow
engine toreturn toidle speedwhen notcutting.
The blade should not turn while the engine is
running at idle. If the blade turns at idle, do not
use your unit. Refer to the Carburetor adjust-
ment section or contact your Authorized Ser-
vice Dealer.

WARNING:
The operator or others
must not try to clear away cut material with the
engine running or the blade turning to avoid
serious injury. Stop engine and blade before
removing materials wrapped around blade or
tube.
