OPERATION AND MAINTENANCE
Unfolding the 7831 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 (un-folded) 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 for field operation even though
the HSL is completely on the ground.
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.
Folding the 7831 HSL

WARNING
1. Tilt the center section and wing assemblies rearward
until they are 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. As the center section
tilts top rearward, the wing assemblies may initially
move inward and then upward (more prevalent
without the wing lock out kit installed.) 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.)
Always unfold the 7831 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 7831 on a level surface and away
from overhead power lines. Keep bystanders and
pets clear of the area.
