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

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.

Note: The following maintenance procedures must be performed or the drivetrain
warranty will be void.
The fi nal drive wheel gearbox, center drive gear motor and the worm gear center drive require pre-
season maintenance. Please refer to the following service information for the above items.
If you should have any questions, please call your Pierce Dealer or Customer Service Representa-
tive.
FINAL DRIVE GEARBOX MAINTENANCE PROCEDURES
A. The fi nal drive gearbox must be serviced as follows after each crop cycle:
1. Inspect input and output shaft seals for leakage. Should either the input or out
put shaft show excessive leakage, the seals should be replaced. All replaced
seals must be installed with generous amounts of #2 Barium/Lithium based grease
or use equivalent quality #2 water-resistant grease.
2. External (dust exclusion) seals should be used to keep dirt and water out of inter-
nal seal locations. If the external seals are damaged or worn, replace with new
seals.
3. The seal drain hole located on both input caps must be kept clear of dirt. Clear the hole
with a 12-gauge wire, nail or punch. Rotate the tool to loosen and remove dirt. Make sure the
vent hole in the expansion chamber is free of dirt or debris.

I - FINAL DRIVE GEARBOX MAINTENANCE PROCEDURES
A. THE FINAL DRIVE GEARBOX MUST BE SERVICED AS FOLLOWS AFTER EACH CROP
CYCLE, A MINIMUM OF ONCE A YEAR.
SEE SECTION “V” “TOW HUB MAINTENANCE” FOR 725-UT TOWABLE GEARBOXES.
SEE SECTION “D” AND “E” FOR ADDITIONAL REQUIREMENTS FOR TNT AND 760
MODELS.
1. Inspect input and output shaft seals for leakage. Should either the input or output shaft seals show
excessive leakage, the seals should be replaced. All replaced seals must be installed with
generous amounts of #2 Barium/Lithium base grease (or use equivalent quality #2 water resistant
grease) on the seal lips.
2. External (dust exclusion) seals should be used to keep dirt and water out of internal seal locations.
If the external seals are damaged or worn, replace with new seals. Note that there are several
different types of seals available.
3. The seal drain hole (on 720 and previous models and on 725 units shipped before October
1996) located on both input caps must be kept clear of dirt. Clear the hole using a 12-gauge wire,
a nail or a punch. Lightly rotate the tool to loosen and remove dirt. CAUTION, DO NOT DAMAGE
THE SEAL CASE OR LIPS. See Diagram FD-1.
4. The vent hole located on the side of the Expansion Chamber must be kept clear of dirt. Use a soft
brush to clear the opening. DO NOT INSERT ANY OBJECTS INTO THE VENT HOLE,

4. Each input and output shaft should be checked for excessive endplay after each
crop cycle. Disconnecting the driveline coupler & tapping the input shaft on both
sides with a dead blow hammer or mallet does this. If play is present, input
shims should be installed to eliminate bearing backlash.
5. All cover and end cap bolts should be torqued to 28-31 ft.-lbs (38-42 N-m).
6. All wheel lug nuts should be torqued to 115-120 ft.-lbs (156-162 N-m).
7. Remove drain plug located at bottom of gearbox and completely drain gearbox.
If oil is contaminated or emulsifi ed, fl ush gearbox with a cup of specifi ed oil and
let drain completely.
8. Replace drain plug and refi ll gearbox through top fi ll hole to the proper operating
level (top of worm gear) as shown below. After one or two hours the oil should be
re-checked. Air may be trapped in the gearbox during initial fi lling. Top off with oil
as needed.
Figure 1-11.
File: ams_srvc_0199.doc Copyright 08/2004
5. Each input shaft should be checked for excessive endplay after each crop cycle, this is done by
disconnecting the drive-line coupler & tapping the input shaft on both sides with a dead blow
hammer or mallet. If any axial endplay is present, input shims should be installed to eliminate the
endplay.
6. Inspect the Hub Cap (Shaft Guard), on the unused side of the input shaft, for looseness, damage
or corrosion. Replace if necessary or if it is missing. This will protect the input shaft and seals
from the elements.
7. All 3/8-16 cover and end cap bolt torque should be 28-31 ft. lbs.
8. All 9/18-18-wheel lug nut torque should be 115-120 ft. lbs.
9. Remove the plug located at bottom of the gearbox and completely drain the gearbox oil. If the oil
is contaminated or emulsified, flush the gearbox with a cup of specified oil and let it drain
completely.
10. Replace the drain plug at the bottom of the gearbox. Fill the gearbox with the proper oil, through
the top fill hole, to the operating oil level range. The oil level range is from the top of the Worm
shank (next to the bearing cone) to the bottom of the oil fill hole (at 70�F ambient temperature)
as shown in Diagram FD-2. Refer to oil specification.

You must lock the pivot out if you are going to:
1. Remove or bypass a guard or other safety device.
2. Place any part of your body into an area on the pivot where there is a pinch point.
3. Work on the electrical circuitry.
4. Obstruct the pivot path (wheel track) with vehicles, equipment, or other obstacles
while performing work on the fi eld itself.
5. Perform structural service which requires equipment to lift spans (i.e. boom
truck).
This standard covers the lockout/tagout procedures
you must use when servicing your Pierce pivot. The
intent of Pierce corporation’s pivot lockout/tagout
standard is to protect you or your workers anytime the
pivot requires servicing. Before any worker performs
maintenance on the pivot where unexpected energiz-
ing, start up release stored energy could occur and
cause injury, the pivot must be isolated and rendered
inoperative. This standard establishes minimum per-
formance requirements for the control of such hazard-
ous energy.
Lockout/Tagout Procedures
Lockout/Tagout Procedures

CP600 Pivot Operators Manual
OPERATION, SAFETY & MAINTENANCE
Section 1-20

Your Pierce pivot requires 480 volt 60
cycle, 3-phase electric power to operate
suffi cient charge. There is also 110-volt
control power throughout the system. Oth-
er potential hazards include any injected
fertilizers and pesticides, and water under
pressure.
Note: Voltage is dependant upon location.
Voltage should not be more than +/- 5%
than the recommended voltage in your
area.
Sequence of Lockout or Tagout Procedure
1. Notify all affected persons that you are about to lockout the pivot, and tell them
why the pivot is being placed “out of service”. Before locking out the pivot, you
must familiarize yourself with the type and magnitude of the pivot’s energy source
and determine any related hazards.
2. If the machine or system is operating shut it down by rotating the forward /
reverse selector switch to the off position.
3. On the main control panel, turn the main disconnect lever to the off position so
the pivot cannot be energized while it is being serviced. Drain all water from the
system and disengage any automatic valves. If your pivot is rigged with an auto
matic valve, it must be locked out so that the pivot does not unexpectedly fi ll with
water while you are servicing.
4. Lockout the main disconnect (energy-isolating device) on the main control panel.
If working down line on the pivot, the tower disconnect switches on the individual
tower boxes must also be shut off.
5. After ensuring that no personnel are exposed, and as a check on having
disconnected the energy source, operate the start button to make certain the
pivot will not operate.
Lockout/Tagout Procedures
CAUTION: Return operating controls to “neutral” or “off” position after
maintenance is completed.
