OPERATING INSTRUCTIONS FOR
USE WITH TRIMMER HEAD
Before trimming, bring engine to a speed suffi-
cient to cut material to be trimmed.
Do not run engine at a higher speed than neces-
sary. The cutting line will cut efficiently when the
engine is run at less than full throttle. At lower
speeds, there is less engine noise and vibration.
The cutting line will last longer and will be less
likely to “weld” onto the spool.
If the trimmer head does not turn when the en-
gine is in operation, make sure the drive shaft
housing is properly seated in engine shroud.
Always release the throttle trigger and allow
the engine to return to idle speed when not cut-
ting.
ADVANCING THE TRIMMER LINE
Advance line by tapping the bottom of the cutting
head lightly on the ground while engine is run-
ning at full speed. The line limiter blade (on un-
derside of shield) will cut the line to the proper
length..
WARNING:
Use only 0.080” (2 mm)
diameter line. Other sizes of line will not ad-
vance properly and can cause serious injury.
Do not use other materials such as wire,
string, rope, etc. Wire can break off during cut-
ting and become a dangerous missile that can
cause serious injury.
OPERATING INSTRUCTIONS FOR
USE WITH BRUSH BLADE
S
Blade Thrust
is a reaction that only occurs
when using a bladed unit. This reaction can
cause serious injury such as amputation.
Carefully study this section. It is important that
you understand what causes blade thrust,
how you can reduce the chance of its occur-
ring, and how you can remain in control of unit
if blade thrust occurs.
S
WHAT CAUSES BLADE THRUST -- Blade
Thrust
can occur when the spinning blade
contacts an object that it does not cut. This
contact causes the blade to stop for an instant
and then suddenly move or “thrust” away from
the object that was hit. The “thrusting” reaction
can be violent enough to cause the operator to
be propelled in any direction and lose control
of the unit. The uncontrolled unit can cause
serious injury if the blade contacts the operator
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 diffi-
cult to see the material being cut. By using
the unit properly, the occurrence of blade
