FINAL CHECKS AND INITIAL OPERATION
The following list of checks and operation procedures should be followed during the ini-
tial start up of the circle. These same basic procedures can also be followed at the initial
start up of each irrigation season.
1. Bolts: Check to insure that all bolts have been properly installed and tightened.
2. Grounding: Be sure the machine is properly grounded. Refer to the Getting Started
and Electrical sections for proper main panel grounding.
3. Control Limit Switches: The limit switches in the tower junction boxes have been pre-
set at the factory, however, they should be checked according to the procedures out
lined in maintenance section, Control Switch Adjustment.
4. Control rods: Check that all control rods are connected to the cam arm.
5. Alignment: The machine should be in a straight line when erection is completed. Ad
just the control rod so the tower safety limit switch roller is in the middle of the “V” of
the cam. Tighten the adjusting nuts. After the machine is started, fi nal alignment
should be performed according to the procedure in maintenance section, alignment.
6. Voltage: Voltage at the pivot panel should be 480V on all three legs of the power
lines.
Note: Voltage is dependant upon your location. Voltage should not be more than
5% higher or lower than the recommended voltage or damage may occur.
7. Lubrication: Check the oil level in all gearboxes and motors. Grease the two fi ttings
on the pivot elbow until grease is visible at the top and bottom of bearing.
8. Starting: When all the above checks have been made, the machine is ready to start.
Close the main panel inner door and turn the main disconnect switch on. Follow opera
tion instructions outlined in Section 4 Panel Operation.
WARNING MAKE SURE POWER IS DISCONNECTED AT THE MAIN SERVICE
PANEL BEFORE PERFORMING ANY ELECTRICAL SERVICE TO THE
MACHINE OR BEFORE OPENING THE INNER DOOR OF THE MASTER CON
TROL PANEL.

Your Pierce Center Pivot irrigation system should be run with a slight leading bow (center towers
ahead of pivot and end tower) in both directions. A correctly aligned machine will have an equal
bow when operated in either direction. DO NOT let the machine run with a large leading bow in one
direction and a lagging bow in the other. To align the machine, follow these steps:
Start at the pivot end of the machine with the machine running in the forward direction and the per-
cent timer set to 75 percent. Stand between tower 2 and tower 3 and sight across motors No. 2 and
1 to the pivot stand pipe. Tower 1 should start when motor 1 appears to be slightly behind and shut
off when it appears to be an equal distance ahead of the center of the standpipe.
When tower 1 is properly aligned, stand between towers 3 and 4 and sight across motors 3 and 2
to the pivot standpipe. Align tower 2 in the same manner as tower 1. As you get to the outer end
of the machine and can no longer see the pivot standpipe, pick a motor on one of the inner towers
and sight to it.
On some towers (#1 for example) it may be desirable to have less forward motion each time the
tower moves. This may be accomplished by loosening the nut on the ball joint disconnect and mov-
ing the ball joint toward the cam. Likewise, a tower can be made to run longer by moving the ball
joint away from the cam. All the ball joint are set at the factory at the mark shown on the cam arm
in the drawing. This is the proper setting for most towers.

Maintenance Check List
• PIVOT: At start of irrigation season, grease pivot bearings. Repeat every 400 hours of
operation.
• GEARBOXES: At start of irrigation season, drain all gearboxes and refi ll with
recommended oil. See Power Drivetrain Maintenance section for detailed information. Refer
ence Section 1-10. and 1-11.
• MOTOR GEARBOXES: At start of irrigation season drain any water that may have
accumulated during the irrigation season and fi ll to the proper level with the proper lubricant.
Reference Section 1-12. and 1-13.
• TIRES: Check tire infl ation (use low pressure tire gauge). Pierce Corporation infl ates all
new tires to a higher pressure for truck loading requirements. Set tire pressure so side wall
has slight fl ex. If tire creases increase pressure. If tire pressure too low tires will lose bead and
damage the tube.
CAUTION: Operating tires below the manufacturers recommended pressure can
result in damage to the tire sidewall in addition to voiding your warranty.
• WHEEL BOLTS: Check to ensure they are tight.
Note: Wheel bolts can loosen after initial installation. They should be checked after 100
hours of operation.
• STRUCTURE: Routinely check pivot, span and tower structures for loose or missing bolts.
• CONNECTORS: Check for leaking gaskets, boots, drains, and malfunctioning sprinklers or
pressure regulators.
