The Control Lever is released from Neutral by mov
ing it to the right and allowing the spring tension to
pull the control lever into one ot the tour forward
speeds. See Figure 2-1.
NOTE
Number 1 position is the slowest tine
rotation speed and number 4 is the
fastest.
Pulling the control lever backwards into the Reverse
