CONTROLS & EQUIPMENT

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.
