moved from the neutral position in the forward direction. The solution flow will turn off if the throttle returns to neutral
or is moved to reverse.
• The solution indicator will be green if the solution is on. If the solution is off, this indicator will be off. The indicator
will be yellow if the solution has been enabled but the throttle is in neutral. If there is a solution system fault, the

the scrub system has been activated. If the scrub system has been turned off and the scrub deck is not up yet, the
indicator will be red. If there is a fault in the scrub system this indicator will flash red.
