WARNING!
Before working with a blade-
equipped unit, always inspect
and clean the area of objects
that could interfere with or
damage the blade.
NEVER
use a blade near
sidewalks, fence posts, build-
ings or other objects that could
cause injury or damage.
Blade Thrust
‘Blade thrust’ is a sudden sideways or
backward motion of the brushcutter.
Such motion may occur when the blade
jams or catches on an object such
as a sapling tree or tree stump. BE
CONSTANTLY ALERT FOR BLADE
THRUST AND GUARD AGAINST ITS
EFFECTS!
Brushcutter Handlebar
A brushcutter’s handlebar helps prevent
the operator from moving forward, or
the unit moving rearward, thus prevent-
ing inadvertent bodily contact with the
blade. ALWAYS KEEP THE HANDLE-
BAR SECURELY IN PLACE ON THE
UNIT!
Using A Brushcutter Blade
NEVER
use a blade for purpos-
es other than those for which it
was designed.
Whenever you strike a hard
object with a blade, always stop
the brushcutter and carefully
inspect the blade for damage.
NEVER OPERATE THE
BRUSHCUTTER WITH A
DAMAGED BLADE!
A blade-equipped machine
must
be equipped with a bi-
cycle-type handlebar as well as
a harness or strap.
ALWAYS
make sure the cutting
attachment shield is properly
installed before operating this
unit.
WARNING!
The cutting attachment must
NEVER rotate at engine idle
speeds!
CAUTION!
Carburetor mixture adjustments
are preset at the factory and can-
not be serviced in the field.
Stopping the Engine
1. Cool the engine by allowing it to idle
for two or three minutes.
2. Slide the ignition switch to the OFF
(O) position.
Checking and Adjusting
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable and must be set
low enough to permit the engine clutch
to disengage the cutting attachment
when the throttle is released.
Adjustment Procedure
1. Start the engine and allow it to idle
2-3 minutes until warm.
2. If the cutting attachment rotates at
engine idle, reduce idle speed by
turning the idle adjustment screw
counter-clockwise. See Figure 23.
3. If a tachometer is available, the
engine idle speed should be final-ad-
justed to 3,000 RPM ±250 RPM.

Adjustment
Screw
Standard Shoulder Strap
Adjust the shoulder strap so the
shoulder pad rests comfortably on the
off-side shoulder and the cutting path
of the blade is parallel to the ground.
Shoulder strap required for use
with brushcutters

Optional Brushcutter Harness
A harness provides additional protec-
tion against blade thrust. In addition, a
harness gives significant support and
comfort to help ensure safe and efficient
operation.
IMPORTANT!
When operating a brushcutter, make
sure both the handle and harness are
adjusted to the size of the operator using
the machine.

WARNING!
Never operate the unit without
a shoulder strap or brushcutter
harness!
