Operating Instructions
Lowering and Raising Air Drill
Lowering/Raising Safety Information
Crushing Hazard During Lowering:
Stay clear of wings and openers during raising and lowering.
Opener sections, in addition to being extremely heavy, are
forced down with hydraulic pressure. Coulter and opener disks
are sharp. During lowering, openers will cut or crush anything
beneath them, and can cause death or serious injury.
Crushing Hazard While Raised:
Fully lower openers when working above or beside them.
Use blocking or stands when working under openers.
Raised wing openers are held up only by hydraulic pressure.
With wings tilted down, openers will slowly lower over time.
They may lower more rapidly if the hydraulic system is
damaged. They will lower suddenly if the hydraulics fail, or
the circuit is set to Float or Retract.
Do not lower while any Air Drill folding operations are
underway or partially complete.
The lift (raise/lower) circuit is also the hydraulic down-
pressure circuit. Hydraulic down-pressure only
functions as intended if the transport locks are set to
FIELD (page 27).
Lowering
1.
Unfold drill before lowering (page 25).
2.
Make sure all persons are clear of opener sections.
3.
Activate dedicated lift circuit (normally Extend).
4.
If down-pressure has been adjusted (page 84), leave
the circuit in Extend.
If down-pressure has not been adjusted, or if not
planting immediately, set the circuit to Neutral.
