When the control bar is cocked to its lowest position as
in Figure 151. The buckling spring is fl exed and moved
to the right end of the rocker arm slot. Another event
takes place inside the rocker arm: The spring-loaded
control hook slides over the cable lever and grasps it so
that when the lever is raised, the BBC cable will come
with it.

Raising the control bar straightens the buckling spring.
Also important is the function of the leaf spring. As the
control bar is raised, the left tip of the control hook slips
by the leaf spring without causing release of the cable
lever.
Continuing to raise the control bar causes the traction
lever to move and the traction cable engages the
transmission.

When the control bar is raised to a point 5” (12.7cm)
below the handle, the BBC cable has been tightened
enough to engage the blade (Fig. 152).
