shoulder pad rests comfortably on the
off-side shoulder and the cutting path
of the cutting attachment is parallel to
the ground. Make sure all hooks and
adjustment devices are secure.

Always wear a shoulder
strap or harness when operating
this unit. Using a harness with a
brushcutter allows you to main-
tain proper control of the unit and
reduces fatigue during extended
operation.

on the outer tube.
Wear the shoulder strap so that the 2.
hook stays at your right hand side.
Adjust the length of the shoulder 3.
strap so that you can hold and oper-
ate the machine comfortably.

Using a shoulder strap when operat-
ing this unit with a blade allows you
to maintain proper control of the unit
and reduces fatigue during extended

Starting A Flooded Engine
Squeezing the throttle lever makes the ■

ing the throttle permits the attachment
to stop moving. If the cutting attach-
ment continues to move when the
engine returns to idle, carburetor idle
speed should be adjusted (see “Adjust-
ing Engine Idle.”)
