CONTROLS  

The location and operation of the controls are 
similar on both the HHT25S and HHT31S 
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.
