Unfold: Check That Openers are Raised
Refer to Figure 33
23. When tilt-down is complete, check that no wing
openers are too close to, or touching the ground.
Review “Lowering/Raising Safety Information” on page 42.
Ground Contact Risk:
Openers must be in the raised position before unfolding. If the
drill has been stored on a hillside for an extended period, there
is some chance that openers on one wing may not be fully
raised.
24. If wing openers are too low on one or both sides,
raise them before unfolding, by extending the lift
cylinders.
25. When vertical movement has stopped (and the
centre section may stop last), hold the openers in the
raised position by setting circuit to Neutral.
26. If no markers are installed, you may also set the
MASTER switch to Off. The CFM is not used in the
field unless markers are installed.
