Starting the Engine
IMPORTANT!
Engine ignition is controlled by a two-position on-off switch mounted on the throttle body. This switch is typically labeled “I” for
ON and “O” for OFF.

IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not flood
the engine with fuel.
CAUTION!
Do not pull the recoil starter to the
end of the rope travel. Pulling the
recoil starter to the end of the rope
travel can damage the starter.
Slide the ignition switch to the “ON”
position. See Figure 16.
Set the throttle lever to the “fast idle”:
Squeeze the throttle lever toward
the handgrip on the shaft tube.
Depress and hold the throttle
lock button.
While depressing the throttle lock
button, release the throttle lever.
See Figure 16.
Press the primer bulb until fuel can
be seen flowing in the transparent
return tube.

WARNING!
Never start the engine from
the operating position.
WARNING!
The cutting attachment may
rotate when the engine is started!
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed posi-
tion, 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.
When the engine starts, slowly move the
choke lever to the “OPEN” position. (If
the engine stops after the initial start,
close the choke and restart.)
Operating the throttle will automati-
cally disengage the fast idle setting.

After the engine starts, allow the
engine to warm up at idle 2 or 3 min
-
utes before operating the unit.
■ After the engine is warm, pick up the
unit and clip on the shoulder strap or
harness if so equipped. See the sec-
tion "Operation" later in this manual.
■ Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should be adjusted (see below)
