SECTION 3 - SPRAYER OPERATION
3.4
The stabilizer assists the break away in keeping the boom in field position. The eye bolt must be adjusted to
preload the stabilizer spring. This is accomplished as follows:
a. Unfold booms from transport position to a configuration where they are still folded in the
middle.
b. The pin for the stabilizer latch should just slide into the hole with 1/16 to 1/8” to spare be-
tween the pin and the eye bolt.
c. If adjustment is necessary loosen the jamb nuts on the eye bolt and adjust the eye to take up
most of the slack on the pin. The pin should still be free to permit removal and insertion.
d. Unfold booms completely and verify pin is tight and spring is preloaded. Pin should not be
able to be removed when boom is in spray position. If pin is loose eyebolt breakage may oc-
cur more often.
5. PART 2 LATCH
Part 2 latches are preset at the factory to a spring installed height of 1-15/16”. Field adjustment of latches may
be necessary to provide enough pressure to suit operator needs. Excessive tightening will increase damages if
the boom strikes a secure object. After adjustment the operator should force part 2 booms to break away insur-
ing that the spring has room to collapse and boom will break away.
6. PIVOT ARM STOP BOLT ADJUSTMENT
Pivot stops are adjusted at the factory, but adjustment may be required due to wear in. Pivot and cylinder stops
must be adjusted at the same time. Adjustment is performed as follows:
1. Place sprayer on a level surface and verify the pivot arms are vertical.
2. Activate tip lift slightly to remove pressure on stop bolts.
3. Adjust bolts to desired position.
4. Retract cylinder to verify that it contacts the stop at the same instant cylinder closes.
5. Cylinder is adjusted by loosening the clevis pinch bolt and turning the clevis to the desired
setting.
6. Tighten clevis pinch bolt after reaching desired setting.
WARNING!
THE OPERATOR MUST ADJUST BOTH
THE BOOM PIVOT STOP AND CYLIN-
DER CLEVIS TO INSURE THAT STOP
BOLTS ARE NOT CONTACTED BEFORE
THE CYLINDER IS COMPLETELY RE-
TRACTED. IF STOPS ARE CONTACTED
BEFORE CYLINDER IS RETRACTED,
THE PIVOT ARM WILL BEND AND IS
NOT COVERED UNDER WARRANTY.
IMPORTANT!
DURING NORMAL OPERATION, BOOMS EQUIPPED WITH HYDRAULIC TIP LIFT SHOULD
REST ON STOP BOLTS. ACTIVATE TIP LIFT ONLY WHEN REQUIRED FOR PROPER GROUND
CLEARANCE.
