Operation
The cutting units should be lowered when going
downhill for steering control.
Selecting Clip Rate (Reel Speed)—The automatic
clip control programmed into the machine controller
requires that it be told at what height of cut the
machine is being operated and whether the machine
is equipped with 5- or 8-blade reels.
When the machine is being operated in such a way
that it can control the reel speed to achieve the
desired clip, the Reel Control light will not light. If
the Reel Control light is illuminated, the traction
speed is too low or too high to allow the machine to
achieve the desired clip.
