The throttle control regulates the engine speed as measured
in rpm (revolutions per minute). Placing the throttle control
in the Fast position can be best for performance. For most
applications, operating in the full throttle position is desirable.

or bystanders.
Always stop the machine and move the motion
control levers to the park position before
adjusting the Smart Speed

control levers (Figure 17).
To turn, release pressure on the motion control lever
toward the direction you want to turn (Figure 19).
The farther you move the motion control levers in
either direction, the faster the machine will move in
that direction.
