Throttle Lever
The throttle lever controls both the throttle and the transmission.
The idle position (normally vertical) is the zero throttle position
and the neutral position for the transmission. A safety ring
(umbrella) keeps the lever from being accidentally moved to
engage the transmission.
To place the transmission into gear, with your hand placed over
the lever ball, pull up on the safety ring (umbrella) and slowly
push the lever into forward gear or slowly pull the lever back
into reverse gear.
Never shift the lever directly from the neutral (vertical) position
into a speed position.
• To prevent damage to the transmission, always allow the
transmission time to engage before accelerating the engine.
• Once the transmission's engaged, you may accelerate as
quickly as you like.

Transmission Lockout
The Transmission Lockout button allows the transmission to be
disengaged while giving the throttle full operating range. With
the lever in the idle position (normally vertical), push the button
located at the bottom of the lever to disengage the transmission.
The throttle may then be operated in any open position (forward
of neutral or back of neutral upright position). Return the throttle
to idle position, and the transmission lockout will automatically
reengage the transmission in neutral position.
