Folding the Drill
Pinch Point and Crushing Hazard. To prevent serious
injury or death:
• Always use transport locks when drill is folded.
• Fold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
• Stay away from frame sections when they are be-
ing raised or lowered.
Keep away and keep others away when folding or un-
folding drill.
Fold the drill on level ground with the tractor in
neutral. If your drill has markers, be certain they
are folded and their control switches are off before
folding.
Refer to Figure 6

3. Move handle on fold latch ahead into road po-
sition.
4. Active hydraulics and slowly fold drill until
wings trigger the spring-loaded fold latch and
are secure in the latch.
Rephasing Lift System
Over a period of normal use the cylinders may get
out of phase. This will cause some drill sections to
run higher than others. To rephase cylinders:
1. Raise the implement completely and hold the
hydraulic remote lever on for several seconds
until all cylinders are fully extended. Do this
every time you raise drill out of ground.
2. When all cylinders are fully extended, mo-
mentarily reverse hydraulic remote lever to re-
tract system 1/2 inch to maintain levelness.
