OPERATION AND MAINTENANCE
4-3
Unfolding the 7833 HSL
WARNING
1.
Tip the top of the center section rearward far enough
to lift the wing frames several inches above the wing
rest saddles located on the hitch. The center section
is tilted backward by extending the large cylinder
located over the hitch (circuit with red hose wrap.)
CAUTION
2.
With the wing frames just above the wing rest
saddles open the wing assemblies up far enough so
that when lowered, they will clear the wing frame
rests located on the hitch. The wing assemblies are
opened (unfolded) by extending the wing fold
cylinders (circuit with yellow hose wrap.)
3.
Once
both
of the wing assemblies are clear of the
wing rests laterally, lower the wing assemblies so that
the wing gauge wheel tires contact the ground or are
in the proximity of the ground. This can be
accomplished by tilting the center section, top
forward (circuit with red hose wrap.)
4.
With the wing gauge wheels in the proximity of the
ground continue opening the wing assemblies by
extending the wing fold cylinders until the wing
assemblies are aligned with the center section
assembly (circuit with yellow hose wrap.)
5.
When the wing assemblies are
aligned
with the
center section extend the large tilt cylinder located
above the hitch. The large tilt cylinder needs to be
extended completely until the cylinder rod end is in
the middle of the mast slot for field operation.
IMPORTANT
Not extending the tilt cylinder completely will inhibit
the HSL from being able to rotate (front to rear) in the
field and may in certain conditions hold the rear of
the machine out of the ground. Extending the tilt
cylinder completely also insures that the draft
compensator system can work correctly.
Machines equipped with tilt control will either have lock
out hardware installed in the mast slot or they will have a
urethane draft cushion. The lock out hardware creates a
rigid hitch while the urethane cushion creates a semi rigid
hitch. One or the other, is required for the tilt controlled
system, since the tracking is controlled by the tilt cylinder.
Folding the 7833 HSL
WARNING
1.
Tilt the center section and wing assemblies by raising
the rear of the HSL upward until it is completely
upright. The center section is tilted upright by
retracting the large tilt cylinder located over the hitch
(circuit with red hose wrap.)
2.
Fold the wing assemblies forward by retracting the
wing fold cylinders. Keep the wing gauge wheels in
the proximity of the ground for safety. Fold the wing
assemblies forward until they are approximately one
foot away from the wing rests (circuit with yellow hose
wrap.)
3.
Tip the center section top rearward far enough to lift
the wing frames several inches above the wing rest
saddles located on the hitch. The center section is
tilted backward by extending the large cylinder
located over the hitch (circuit with red hose wrap.)
4.
With the wing assemblies just above the wing rest
saddles, further retract the wing fold cylinders to
position the wing assemblies over the wing rest
saddles (circuit with yellow hose wrap.
5.
With the wing assemblies over the wing rest saddles,
lower the wing assemblies into the wing rest saddles
by further retracting the large tilt cylinder over the
hitch. Retract the large tilt cylinder until the wings are
at rest in the wing rest saddles (circuit with red hose
wrap.)
Synchronizing and Leveling
Front Gauge Points
The front gauge is comprised of the main wheels and
tires on the hitch frame and the gauge wheels and tires
on the wing frames. The 7833 comes standard with
walking beam wing front gauge wheels.
Always unfold the 7833 on a level surface and
away from overhead power lines. Keep
bystanders and pets clear of the area.
Do not lift the wing assemblies more than a few
inches above the wing rest saddles when the
wing assemblies are folded forward.
Always fold the 7833 on a level surface and away
from overhead power lines. Keep bystanders and
pets clear of the area.
