Throttle lock
• Make sure the throttle control is locked at the idle setting
when the throttle lock is released.
• Press the throttle lock and make sure it returns to its
original position when you release it.
• Check that the throttle control and throttle lock move freely
and that the return springs work properly.
• The throttle lock is designed to prevent accidental
operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle
control and the throttle lock 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
