Unfolding Safety Information
Roll-Away Hazard:
Unfold only on hard level ground. Allow ample room. Drill,
tractor, or both must be free to move during unfolding. On a
slope, roll away could occur, causing an accident resulting in
death, serious injury and substantial property damage.
Electrocution Hazard:
Keep clear of overhead power lines when unfolding, operating,
folding or transporting the drill. Machine is not grounded. At
higher voltages, electrocution can occur without direct
contact. Any line voltage present on implement, cart or tractor
can cause severe injury or death.
Pinch Point and Crushing Hazards:
Keep people away from the drill and tractor during unfolding.
The distance between the tractor and the seed structure
decreases by 3.2 m (7.5 feet) during unfolding. Drill, tractor,
or both will move during this operation. Wings will tilt down
and swing out. Risks include:
▲ Pinching or crushing at pivot points and at multiple sites in
pivoting assemblies. Stay clear of the wing sweep arcs.
Coulters and row openers are sharp.
▲ Crushing under lowering/moving wing wheels, under
moving transport wheels, under lowering wings or under
lowering openers.
Falling Hazard - Tires Not a Step:
Do not use tires as steps or platforms. Wing gauge wheel tires
are off the ground in transport lift. Front and rear main
transport tires may be lifted and free to spin on unlevel ground
and at some weight-transfer and row down-force settings.
General Cautions:
▲ Unfold only with markers resting in transport cradles.
▲ Unfold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
Do not unfold with openers lowered, or machine damage will
result.
To avoid serious injury or death from crushing:
Machine moves rearward when fold ng wings forward.
Stay away from machine while folding and unfolding
