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 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 stick edger. The stick edger will
not return to idle, and the 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 a cold engine and after
refueling an engine that has run out of fuel.
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 crank the engine for starting.
