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

“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

reserves the right to determine, in its sole discretion, what constitutes
a significant new feature and Major Upgrade.

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:
CWARNING – This alert warns of a potential hazard, which, if not avoided, can cause severe
injury.
CCAUTION – This alert warns of a hazard or unsafe practice which, if not avoided, can cause
injury or damage.
Note – An absence of specific alerts does not mean that there are no safety risks involved.
Warnings
CWARNING – When you are working on the vehicle’s hydraulic systems, vehicle attachments
that are 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.
CWARNING – If someone else attempts to drive the vehicle while you are working on or under
it, you 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.
CWARNING – Agricultural chemicals can pose serious health risks. If the vehicle has been used
to apply agricultural chemicals, steam clean the vehicle to remove any chemical residue from
the areas of the vehicle where you will be working.
CWARNING – Vehicle cabs can be quite high in the air. To avoid potentially serious injury
through falling from this height, always use the steps and handrails, and face the vehicle, when
you enter or exit it.Add the following warnings.
CWARNING – THE EZ-PILOT ASSISTED STEERING SYSTEM IS SOLELY INTENDED FOR
AGRICULTURAL USE IN AN 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
4
Cautions
CCAUTION – When the vehicle has been running, parts of the vehicle, including the engine and
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.
CCAUTION – The system installation may bring you into contact with chemical substances, such
as oil, which can cause poisoning. Wash your hands thoroughly after you finish working on the
system.
CCAUTION – Battery posts, terminals, and related accessories contain lead and lead
compounds, which can cause serious illness. To avoid ingesting lead, wash your hands
thoroughly after touching the battery.
CCAUTION – Always wear protective equipment appropriate to the job conditions and the
nature of 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.
CCAUTION – Parts of the vehicle may be under pressure. To avoid injury from pressurized parts,
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.
CCAUTION – Do not direct pressurized water at:
- 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.
CCAUTION – To avoid malfunctions, or damage to cables:
- 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.
