2. When the Rear handle is rotated 45 or 90 degrees clockwise or
counterclockwise, the Knock button (G) engages with the dent (H)
of Rear handle and makes click noise.
Throttle trigger (K) is pulled in this position, Throttle stopper (C) is
pushed to the front by part (L) of Throttle trigger.
Then, The projection part (E) of Throttle stopper engages with dent
(F) of Handle fixture to stop rotating of Rear handle.
On the other hand, when the Throttle stopper (C) is pushed to the
front, the connection of the neck (M) of Latch comes off from Throttle
stopper (C).
Then the Latch (A) is pushed and moved toward outside by the
Spring (N).
And the head (B) of Latch prevents the Throttle stopper (C) from
moving backward.
3. When projection (E) of Throttle stopper (C) doesn't engage with
dent (F) of Handle fixture, Throttle stopper (C) doesn't move to the
front even if Throttle trigger (K) is pulled, and the movement of part
(L) of Throttle trigger is obstructed by Throttle stopper (C).
Therefore the Throttle trigger can't be pulled, and engine rotation
isn't raised.
