Limited Warranty Terms and Conditions
Product Limited Warranty
Subject to the terms and conditions set forth herein, Trimble
Navigation Limited (“Trimble”) warrants that this product and its
internal components (the “Product”) shall be free from defects in
materials and workmanship and will substantially conform to Trimble’s
applicable published specifications for the Product for a period of one
(1) year, starting from the earlier of (i) the date of installation, or (ii) six
(6) months from the date of original Product shipment from Trimble.
Product Software
Product software, whether built into hardware circuitry as firmware,
provided as a standalone computer software product, embedded in
flash memory, or stored on magnetic or other media, is licensed and
not sold. If accompanied by a separate end user license agreement,
use of any such software will be subject to the terms of such end user
license agreement (including any differing limited warranty terms,
exclusions and limitations), which shall control over the terms and
conditions set forth in this limited warranty).
Software Updates
During the limited warranty period you will be entitled to receive such
Fix Updates and Minor Updates to the Product software that Trimble
releases and makes commercially available and for which it does not
charge separately, subject to the procedures for delivery to purchasers
of Trimble products generally. If you have purchased the Product from
an authorized Trimble distributor rather than from Trimble directly,

Update to the Trimble distributor for final distribution to you. Major
Upgrades, new products, or substantially new software releases, as
identified by Trimble are expressly excluded from this update process
and limited warranty. Receipt of software updates shall not serve to

For purposes of this warranty the following definitions shall apply: (1)
“Fix Update” means an error correction or other update created to fix
a previous software version that does not substantially conform to its
published specifications; (2) “Minor Update” occurs when
enhancements are made to current features in a software program;
and (3) “Major Upgrade” occurs when significant new features are
added to software, or when a new product containing new features
replaces the further development of a current product line. Trimble
reserves the right to determine, in its sole discretion, what constitutes
a significant new feature and Major Upgrade.
Warranty Remed ies
If the Trimble Product fails during the warranty period for reasons
covered by this Limited Warranty and you notify Trimble of such failure
during the warranty period, Trimble at its option will repair OR replace
the nonconforming Product, OR refund the purchase price paid by you

Safety Information
Always follow the instructions that accompany a Warning or Caution. The information they
provide is intended to minimize the risk of personal injury and/or damage to property. In
particular, observe safety instructions that are presented in the following format:
WARNING – This alert warns of a potential hazard, which, if not avoided, can cause severe injury.
C
CAUTION – This alert warns of a hazard or unsafe practice which, if not avoided, can cause injury or
C
damage.
Note – An absence of specific alerts does not mean that there are no safety risks involved.
Warnings
WARNING – When you are working on the vehicle’s hydraulic systems, vehicle attachments that are
C
suspended can drop. If you are working around the vehicle, you could suffer serious injury if an
attachment dropped on you. To avoid this risk, lower all vehicle attachments to the ground before
you begin work.
WARNING – If someone else attempts to drive the vehicle while you are working on or under it, you
C
can suffer serious or fatal injuries. To avoid this possibility, install a lockout box on the battery
terminal to prevent the battery from being reconnected, remove the key from the vehicle’s ignition
switch, and attach a “Do not operate” tag in the cab.
WARNING – Agricultural chemicals can pose serious health risks. If the vehicle has been used to
C
apply agricultural chemicals, steam clean the vehicle to remove any chemical residue from the areas
of the vehicle where you will be working.
WARNING – Vehicle cabs can be quite high in the air. To avoid potentially serious injury through
C
falling from this height, always use the steps and handrails, and face the vehicle, when you enter or
exit it. Add the following warnings.
WARNING – THE EZ-PILOT STEERING SYSTEM IS SOLELY INTENDED FOR AGRICULTURAL USE IN AN
C
OPEN FIELD ENVIRONMENT WITH AGRICULTURAL VEHICLES APPROVED BY THE MANUFACTURER
FOR USE WITH THE EZ-PILOT SYSTEM, AND SHOULD NOT BE USED WITH ANY OTHER TYPE OF
VEHICLE OR FOR ANY OTHER PURPOSE.
Contact your local EZ-Pilot system reseller or check www.trimble.com to confirm that the EZ-Pilot
system has been tested and approved by the manufacturer for use with your vehicle make and
model. The EZ-Pilot system should not be installed on a vehicle not approved by the manufacturer
for such use. Installation of the EZ-Pilot system on an unapproved vehicle will invalidate the product
warranty.

Safety Information
Cautions
CAUTION – When the vehicle has been running, parts of the vehicle, including the engine and
C
exhaust, can become extremely hot and can cause serious burns. To avoid burns, allow hot machine
parts to cool before you begin working on them.
CAUTION – The system installation may bring you into contact with chemical substances, such as oil,
C
which can cause poisoning. Wash your hands thoroughly after you finish working on the system.
CAUTION – Battery posts, terminals, and related accessories contain lead and lead compounds,
C
which can cause serious illness. To avoid ingesting lead, wash your hands thoroughly after touching
the battery.
CAUTION – Always wear protective equipment appropriate to the job conditions and the nature of
C
the vehicle. This includes wearing protective glasses when you use pressurized air or water, and
correct protective welder’s clothing when welding. Avoid wearing loose clothing or jewelry that can
catch on machine parts or tools.
CAUTION – Parts of the vehicle may be under pressure. To avoid injury from pressurized parts,
C
relieve all pressure in oil, air, and water systems before you disconnect any lines, fittings, or related
items. To avoid being sprayed by pressurized liquids, hold a rag over fill caps, breathers, or hose
connections when you remove them. Do not use your bare hands to check for hydraulic leaks. Use a
board or cardboard instead.
CAUTION – Do not direct pressurized water at:
C
- electronic or electrical components or connectors
- bearings
- hydraulic seals
- fuel injection pumps
- any other sensitive parts or components
Set the hose pressure as low as practicable, and spray at a 45° to 90° angle.
Keep the nozzle of the power washer away from the machine at the distance recommended by the
manufacturer.
CAUTION – To avoid malfunctions, or damage to cables:
C
- route cables away from areas where they may be pinched or rubbed.
- do not alter cable lengths and connections. If you must alter the length of the power cable do not
remove the fuse or fuse holder from the cable.

WARNING – To avoid potentially serious personal injury or illness, and to prevent damage
to equipment, make sure that you read and understand the Safety Information chapter.
Preparing the vehicle
1. Park the vehicle on a hard, level surface.
2. Engage the park brake and then remove the ignition key.
3. On an articulated vehicle, install the articulation locks.
4. Remove all dirt and debris from the areas of the vehicle where the system is to be installed.
5. Open all kit boxes and lay all of the parts out on a clean workbench.
6. Check the contents of the boxes against the packing lists.
Note – The left and right sides of the vehicle are referenced while standing behind the vehicle,
facing the normal direction of travel.

B
Tip – If the spacer becomes
stuck on the telescopic lock
stem, use slip-joint pliers and
rotate the spacer to remove
it.
Step 7
Pull the steering wheel for your
machine, as described below.
AGCO/AgChem Rogator sprayers
and TerraGator floaters
Use a steering wheel puller.
Example tool:

CAUTION – If the column moves left or
right, the pivot point is worn. Do not
proceed with the installation: You
must replace the steering column.
There is no repair kit available for this
problem, which causes degraded
steering accuracy in the EZ-Pilot
system. The steering column will
produce excessive noise and
rotational motion when the EZ-Pilot
motor is operating.
