HYDRAULIC
4-28.3 With both markers in the raised posi-
tion, slowly engage the marker hydraulics.
One marker will extend. Reversing the hy-
draulic lever will raise that marker.
4-28.4 Slowly engage the marker hydraulics
again and the opposite marker will extend.
4-28.5 Reverse the marker hydraulics again
and that marker will rise.
4-28.6 The marker unfold/fold process will then
repeat itself.
CAUTION
MARKER BLADES ARE VERY SHARP,
USE GLOVES WHEN WORKING
AROUND MARKER BLADES.
4-28.7 Insure that the marker hydraulic system
is full of oil before attempting to fold or unfold
the markers. If a hydraulic component is re-
moved, repaired, or replaced the system
must be purged of air before folding/unfold-
ing the markers. To purge the system of air,
unpin the rod end of both marker cylinders.
Align or prop the cylinders into position so
that the rod will not interfere with anything
during its travel. Slowly engage the tractor
hydraulics fully extending and retracting both
marker cylinders. Repeat several times until
the action of both cylinders is positive and
immediately responsive. Do not loosen or
crack any fittings. Reconnect the rod end of
both cylinders.
