Operating The Controls - Honda HHT25S Owner's Manual

Operating the Controls

The location and operation of the controls are similar on both the
HHT25S and HHT35S models.
Choke Lever
The choke lever opens and closes the choke valve.
The CLOSED position enriches the fuel mixture for starting a cold
engine.
The OPEN position provides the correct fuel mixture for operation
after starting, and for restarting a warm engine.

Ignition Switch
The ignition switch controls the ignition system.
The ignition switch must be in the ON (I) position for the engine to
start and run.
Moving the ignition switch to the STOP (O) position stops the engine.

Operator Presence Lever
The operator presence lever blocks the throttle trigger. This safety
feature prevents unintentional throttle operation if the trimmer is
bumped while the operator's hand is not on the control handle.
When the operator presses the presence lever by gripping the control
handle, the trigger moves freely.

Throttle Trigger
The throttle trigger controls engine speed.
Pulling the throttle trigger toward the control handle grip increases
engine speed. The trimmer will have the greatest cutting force at
maximum engine speed.
Releasing the throttle trigger reduces engine speed. At idle, the
cutting attachment should coast to a stop.

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.
