THROTTLE LOCKOUT
The throttle lockout is designed to prevent accidental operation
of the throttle control. When you press the lockout (2) (i.e. when
you grasp the handle) it releases the throttle control (see Fig.
21).
When you release the handle, the throttle control and the
throttle lockout both move back to their original positions. This
movement is controlled by two independent return springs. This
arrangement means that the throttle control is automatically
locked at the idle setting.
Make sure the throttle control is locked at the idle setting when
the throttle lockout is released.
Press the throttle lockout and make sure it returns to its original
position when you release it.
Check that the throttle control and throttle lockout move freely
and that the return springs work properly.
See instructions under the heading Start. Start the hedge
trimmer and apply full throttle.
Release the throttle control and check that the blades stop and
remain stationary.
If the blades move when the throttle control is in the idle
position then the carburettor idle setting must be adjusted.
STOP SWITCH
Use the stop switch to switch off the engine. (see Fig. 22)
Start the engine and make sure the engine stops when you
move the stop switch to the stop setting.
