Marker Safety Information
Electrocution Hazard:
Keep clear of overhead power lines when operating markers.
The markers can reach 7.3 m (24 feet) above ground level
during folding and unfolding. If a marker gets too close to, or
contacts a power line, nearly all metal parts of the tractor and
drill will have lethal voltage present, and anyone touching
them can complete the circuit to ground, resulting in serious
injury or death. With very high voltages, electrocution can
occur without direct contact.
Overhead Marker Hazard:
To prevent serious injury or death, do not allow anyone to
stand near or beyond the end of the wings during marker
operations. You may be injured if hit by a folding or unfolding
marker. Markers may fall quickly and unexpectedly if the
hydraulics fail. Marker arms are heavy and marker discs may
be sharp.
Marker Pinch Point/Shear Hazard:
To prevent serious injury or death, do not allow anyone to
stand near the end of the wings or and part of the markers
during marker operations. The marker mechanism has
numerous points where crushing or shearing injury can occur.
Sudden Marker Movement Risk:
To prevent unexpected marker operation, leave CFM Marker
switch off (down) when markers are not in use.
Machine Damage Risk:
Operate markers only with drill completely unfolded.
Extending a marker when tilted up may damage drill systems.
Extending a marker when folded may damage the tractor.
