CONTROLS & EQUIPMENT
Throttle Set Button
The throttle set button is used to hold the throttle
trigger at the fast idle position for starting. Do not
allow the cutting line or blade to contact any
obstruction when starting the engine with the
throttle set button engaged.
To engage the throttle set button, press the
operator presence lever by gripping the control
handle, pull the throttle trigger, then press and
hold the throttle set button while releasing the
throttle trigger.
To disengage the throttle set button, simply pull
the throttle trigger. The throttle set button
automatically disengages when the throttle
trigger is pulled.
Do not use the throttle set button while operating
the trimmer. The trimmer will not return to idle,
and the cutting-line head or blade will continue to
spin until the throttle set button is disengaged
and the throttle trigger is released.
Priming Bulb
Pressing the priming bulb pumps fuel from the
fuel tank to the carburetor. This procedure is
necessary for starting the engine.
To ensure fuel has reached the carburetor, press
the priming bulb repeatedly until fuel can be seen
in the clear plastic fuel return tube.
Recoil Starter Grip
Pulling the starter grip operates the recoil starter
to turn the engine for starting.
