Operation
The DCS Control is now ready to grind/scarify. Long
press down on the Handlebar Rocker Switch to lower
the cutter head to your Cut Depth Target. Short press up
or down on the switch to adjust your Cut Depth on the
fly. When finished with your cut, long press up on the
switch to raise the cutter head to the Home position.
NOTE: The Zero Point and Cut Depth are referenced
from the Home position. Recalibrate your DCS Control
periodically by pressing the Home button or long press-
ing up on the Handlebar Rocker Switch.
NOTE: Pressing any button while the cutter head is
moving to Zero or Cut Depth will stop the command and
halt the cutter head from moving any further up or down
until another button is pressed.
Manual Height Adjustment
If the DCS Control is not usable (dead battery, etc.), the
cutter head height can be adjusted using the Manual
Height Adjustment feature.
1. Remove fuse from fuse holder near positive battery
terminal. This will protect the battery from damage.
2. Use a 6mm hex key to remove the screw plug on
the top of the linear actuator.

head cutter head; rotate clockwise to raise the
cutter head. Max rotation speed of 1 revolu-
tion per second. Do not use power tools in
the Manual Height Adjustment port.
