Center Pivot 7000, 8000, 8120 Series 69
MAINTENANCE
Barricade
Maintain the barricade structure and area.
Inspect the barricade structure for failure and tighten
any loose hardware completely.
Ensure that the actuator arm contacts the tripping
structure. Under certain conditions, soil may build up
in the wheel track resulting in a ramp effect. This may
allow the actuator arm to go over the top of the struc-
ture which trips the actuator arm. See Figure 69-1.
Should this happen, the machine will not stop but
continue to move and can result in damage to the
machine. Remove any build up of soil in the barricade
area.
Wheel Tracks
It is important to maintain wheel tracks. See Figure
69-2.
•
Ensure correct tire pressure to help reduce the
possibility of deep wheel tracks.
•
Wheel track depth:
»
Regular drive units must not exceed 4 in (101
mm).
•
Wheel track depth can be controlled by various
methods, which include larger tires, dry wheel
track sprinkler packages, boombacks, wide-flat
berms, drag socks, etc.
Engine/Generator
Refer to the Owner’s Manual supplied with engine/
generator for specific details on maintenance, opera-
tion, and winterizing of the engine/generator.
!
CAUTION
• A PARTIALLY FILLED FUEL TANK WILL PER-
MIT CONDENSATION WHICH WILL CONTAMI-
NATE THE FUEL AND ACT TO DAMAGE THE
INJECTION PUMP AND INJECTORS.
