Operation
5-14 August 2014 C2 Contour Air Drill
Work Switch
(Optional equipment)
The pressure work switch activates the Air Cart Metering
system by the hydraulic pressure on the opener lift side.
When the openers are raised the switch opens at a
pre-set pressure turning off the Air Cart metering and
when lowered the switch closes at the pre-set pressure
to turn on the metering.
The pre-set Factory set point meets most operators’
preference. If the turn ON and OFF time needs to be
adjusted follow the procedure below:
• Remove cover from back of switch.
• Insert a 3/32” allen wrench into the adjustment screw
opening. Turn the screw clockwise to increase the
set point or counter clockwise to decrease.
- Increasing set point will cause the metering system
to turn ON quicker . This will also cause the
metering system to turn OFF later.
- Decreasing set point will cause the metering
system to
turn ON later
. This will also cause the
metering system to turn OFF quicker.
