SECTION 2 - OPERATION
page 2-4
CAUTION!
FOLDING AND UNFOLDING
NOTE: Read this section before folding or unfolding the air drill.
The air drill is equipped with a manual depth control safety
lock system. The safety lock system is a mechanical
backup that will stop the drill from suddenly dropping
should the depth control hydraulic system fail (i.e.,
hydraulic hose failure).
Keep everyone clear of the machine when folding
or unfolding wings.
Be sure cylinder and attaching hoses are fully
charged with oil before operating system. Failure
to do so will allow wings to fall rapidly.
To avoid injury or death, do not contact electric
lines.
To avoid injury or death stand clear of machine
when wings are being folded or unfolded.
Mechanical or hydraulic failure can allow wings to
fall rapidly.
To avoid injury or death, do not adjust while
machine is in motion.
To avoid injury or death, ensure mechanical lock-
up hardware is installed before transporting or
servicing machine. Hydraulic failure can allow
openers to fall rapidly.
IMPORTANT: Never try to wing up the drill without having the frame raised all the way. If the drill is winged
up with the frame down, damage to the machine could result. Never lower the frame with the
drill in transport position.
