Never attempt to shift without the engine running.
A one-hand, single-lever control operates as both a gear shifter and a throttle. The lever automatically locks in the neutral position (straight up and down) for safety. The lever can be moved from neutral only by raising the lifter under the ball knob.
Shifting is accomplished by moving the lever into the first 45 degrees of travel. Moving the lever forward engages the running gear; moving it back from center puts the drive train into reverse. By advancing the lever beyond 45 degrees you move from the shifting range to the throttle range.
Do not attempt to shift without the engine running! The shift mechanism of this control can be temporarily disengaged by engaging in the black button in the side of the throttle handle. This allows the engine to increase RPM in neutral during warm-up.
