For fast speed, press upper half of rocker switch
(indicated by rabbit symbol).
NOTE: To adjust preset fast or slow speeds with
adjustable High-Low Speed Select Rocker Switch:
1. Select middle position (ADJ) or slow (turtle)
position on the optional Adjustable Three-State
Speed Select Rocker Switch (A).
2. Press and hold top or bottom half of Bump
Speed Enable Rocker Switch (B) while using
Speed Select Rocker Switch (C).
3. Use Speed Select Rocker Switch (C) to bump
engine speed up (+) or down (-).
NOTE: Slow (turtle) position is factory preset at low
engine idle, while middle (ADJ) position is factory
set at high engine idle.
NOTE: Once the speed has been set, the Bump Speed
Enable Switch (B) must be pressed and released
three times within two seconds to commit the new
slow or fast speed to memory. If not done, the
engine’s new slow or fast speed will only be
effective until the key is shut off. Then the speed
will revert to its previous setting.
Changing engine speed using optional analog
potentiometer throttle (D)
NOTE: Pushing in on analog potentiometer will
immediately take engine to slow idle speed.
1. Set High-Low Speed Select Rocker Switch (A) to low
speed position.
2. Turn potentiometer throttle clockwise to increase speed
or counterclockwise to decrease speed.
NOTE: Engine Control Unit (ECU) reads the higher of the
High-Low Speed Select Rocker Switch or the
Analog Throttle(s) Speed Settings. With High-Low
switch at low speed, Analog Throttle(s) will control
speed higher than low idle setting.
