When the Engine Starts...
 After the engine starts, allow the engine
to warm up at idle 2 or 3 minutes before
operating the unit.
 After the engine is warm, pick up the
unit and clip on the shoulder strap if so
equipped.
 Advancing the throttle makes the cut-
ting attachment oscillate faster; releas-
ing the throttle permits the attachment
to stop oscillating. If the cutting attach-
ment continues to oscillate when the
engine returns to idle, carburetor idle
speed should be adjusted (see “Adjust-
ing The Carburetor” on this page).
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded
with fuel. If flooding is suspected,
move the choke lever to the open position
and repeatedly pull the recoil starter to
remove excess fuel and start the engine.
If the engine still fails to start, refer to the
troubleshooting section of this manual.
5. When the engine starts, slowly move
the choke lever to the “OPEN” position.
