The engine can only be started with the control lever
in the neutral position.

and engine at idle.

motion.

Adjusting the friction brake
The control lever is fitted with a friction brake that can
be adjusted to apply more or less resistance to lever
movement. Adjust the friction brake by turning the
screw (control A), or by twisting the lever (control B).
Turn clockwise (+) for stiffer lever movement, and
counterclockwise (–) for easier movement.
