Control Handle - Stihl SR 320 Instruction Manual

Control Handle

The control handle has two functions. It is used to aim
the airstream or the spray in the required direction.
The controls (stop switch, throttle trigger and setting
lever) are used to select the required engine operating
condition.
The stop switch (1) shuts down the engine. The engine is
ready to start when the stop switch is in the "I" position.
Ignition is interrupted, i.e. the engine stops or will not
start, when the stop switch is in the "0" position.
Engine speed can be infinitely varied between idling and
maximum speed with the throttle trigger (2).
The setting lever (3) enables any engine speed or throttle
position between idling and maximum speed to be
selected and held. To do this, swing the setting lever
upward to the required position. The setting lever auto-
matically remains in the position. selected. The engine
runs at idling speed when the setting lever is moved back
to its lower end position (see illustration). Always move
the setting lever to this end position before shutting down
the engine.
The mistblower's control handle also features a stop cock
for the spray mix. Its lever (4) must be set parallel to the
pleated hose for maximum flow and returned to the verti-
cal position to shut off the flow.
