MAINTENANCE
80 Center Pivot 7000, 8000, 8120 Series
Machine Alignment
The machine is initially aligned when it is installed.
However, for various reasons it may become neces-
sary to adjust the alignment.
!
WARNING
• DO NOT ALIGN THE MACHINE WHEN THERE
ARE ESTABLISHED WHEEL TRACKS. WHEEL
TRACKS MUST BE REMOVED BEFORE
ALIGNING THE MACHINE TO REDUCE THE
POSSIBILITY OF STRUCTURAL DAMAGE.
Alignment should be checked annually and adjusted
before there are wheel tracks.
Alignment is an important factor in the operation of
the machine. A misaligned machine develops very
high stresses which could cause structural damage
and reduce expected motor and gearbox life.
A leading bow creates extreme tension or linear pull-
ing force over the entire machine. See Figure 80-1.
A trailing bow creates extreme compressing or linear
pushing force on the entire machine. When the spans
are compressed, they lose their inherent strength.
See Figure 80-1.
!
WARNING
• A TRAILING BOW IN EITHER DIRECTION IS
NEVER ACCEPTABLE AND MAY RESULT IN
SEVERE STRUCTURAL DAMAGE.
NOTE
• If the irrigation machine is operated in forward
and reverse, a leading bow in one direction
becomes a trailing bow in the other direction.
Therefore, such a machine should be aligned
to operate in as straight a line as possible.
