1.1 General
1.1.1 Notes on documentation
To ensure that the information is structured in a user-friendly manner, the service documentation is divided
into the operator's manual and the workshop manual.
The operator's manual includes a general description as well as instructions for all necessary maintenance
work.
Knowledge of the owner's manual is essential to understand the workshop manual. This is particularly
important for safety instructions. The workshop manual describes repairs to assemblies and components
that will require more effort and suitably qualified specialists to carry out.
Note
This workshop manual provides notes for trained technicians to maintain our tractors. Read and observe
the information in this documentation. This will help you prevent accidents and safeguard the
manufacturer's warranty.
The respective accident prevention rules as well as other generally recognized safety and occupational
health rules must be observed.
The tractor is built solely for the purpose defined by the implement manufacturer. Any other type of use is
considered unauthorized. The manufacturer bears no liability for any damage resulting from improper use.
The user bears this risk alone. Intended use includes maintaining operating, service and maintenance
conditions as specified by the manufacturer.
Operation, maintenance and repair of the tractor may only be carried out by people who are familiar with
this equipment and aware of the associated dangers. Ensure that this documentation is available to and
understood by everyone involved in operation, maintenance and repair. Not observing this documentation
can lead to faults, damage and personal injury, for which the manufacturer assumes no liability. The
prerequisite for the tractor being correctly serviced and maintained is the perfect condition and availability
of all necessary equipment, standard tools and general workshop equipment as well as special tools.
Special tools must only be used where absolutely necessary. The tools are displayed where they need to
be used in each case.
The machine must be maintained according to its proper use. Always replace parts with genuine FENDT
spare parts! When ordering parts, please provide the chassis number as per the most up-to-date spare
parts documentation.
Only parts approved by the manufacturer for that specific purpose may be used for any alterations. The
manufacturer will not accept liability for any damage resulting from unauthorized modifications to the
tractor. Non-compliance invalidates the warranty!
Workshops should also refer to documentation on maintenance work and technical data. Once
maintenance is complete, take a test drive to ensure the vehicle's correct operation and road safety.
We reserve the right to make design changes in light of technical developments.
Notes on repairs
The assembly/disassembly instructions shown correspond to the design status at the time the workshop
manual was drawn up.
Further technical development of the product and additions related to different versions may require
alternative working processes that do not pose too many difficulties to trained and qualified specialists.
These assembly/disassembly instructions shall be invalidated upon issue of the next version of this
document.

1.1.2 Safety instructions and measures
Important notes on work safety
The statutory accident prevention regulations (available from professional associations or specialist shops)
must be observed. These depend on the operating site, operating mode and fuels and lubricants used.
Special protective measures dependent on the respective procedures are specified in the corresponding
repair guidelines and highlighted.
This handbook uses the following safety tips
DANGER: Indicates an impending dangerous situation that will lead to serious injury or
death if not avoided.
WARNING: Indicates a potentially dangerous situation that could lead to serious injury or
death if not avoided.
CAUTION: Indicates a potentially dangerous situation that could lead to minor injury if not
avoided.
Please observe the following when carrying out maintenance or service work to the tractor:
Only the documentation associated with the vehicle (workshop manual and operator's manual) must be
used to complete any pending work.
1. General
• Only briefed personnel may operate the tractor or carry out maintenance work.
•Only use qualified specialists to carry out repairs or service work.
• Nobody may be in the cab while work is being carried out under the jacked-up tractor.
• Relieve pressure from implement lines, e.g. to the front loader.
• All people should keep clear of a lifted, unsecured load (e.g. tilted cab etc.).
• Never open or remove any safety devices while the engine is running.
• Pressurized fluids (fuel or hydraulic oil) escaping under high pressure can penetrate the skin and cause
severe injuries. If this should occur, seek medical advice immediately to avoid the risk of serious
infection.
• Keep at a safe distance from hot areas.
• Pressure accumulator and connected pipes are highly pressurized. Only remove and repair in
accordance with instructions provided in the workshop manual.
• To avoid eye injury, do not look directly at the surface of the activated radar sensor.
• Dispose of oil, fuel and filters properly!
• Specialist knowledge and special fitting tools are required to fit tires.
• Run the tractor for a short time, then retighten all wheel nuts and bolts and check them regularly.
For correct torque values refer to TECHNICAL DATA.
• Before working on the electrical system, always remove the earth strap from the battery. Observe the
following when carrying out electric welding. Before carrying out welding work on tractor or mounted
implements, ensure that both battery terminals are disconnected. Attach the welding appliance's earth
terminal as close to the welding spot as possible.
• Caution is required when dealing with brake fluid and battery acid as these are toxic and corrosive!
• Only use genuine FENDT spare parts.
2. Working on the front-axle suspension
• The front axle suspension pressure lines between the central control block (ZSB) and the suspension
cylinders, and

• the cased ASPL, ASPR and ZSP pressure accumulators
DANGER: are under 200 bar pressure, even when the engine is switched off and the
suspension is lowered (= locked).
Safety measures:
Prior to each repair and after releasing or opening in this area, the pressure must be
released manually.
NOTE:
The "Lock suspension/lower suspension" command has no effect!
Even externally energizing the solenoid valves Y013 - lower suspension solenoid valve and Y065 -
suspension raising solenoid valve has no effect!
(There are hydraulic pilot-operated non-return valves built in)
To release pressure:
• Screw in the knurled-head screw on the MVFS
[Y013] - Suspension lowering solenoid valve;
the chassis may be lowered
• Screw in the knurled-head screw on the MVFH
[Y065] - Suspension raising solenoid valve;
the rebound accumulator will be relieved

Fig. 1
Check:
As the oil temperature rises, the emptying accumulator will make a flowing sound
(barely audible in winter).
3. Working on the brake system
DANGER: The brake system hydraulic
lines remain under pressure even
when the engine has been switched
off!
Safety measures:
Before each repair to the brake
system or when removing the cab,
the pressure must be relieved
manually.
To release pressure:
1. Engine must be off
2. Secure the tractor to prevent it from rolling
away.

area.
• Never let the engine run in enclosed spaces with no exhaust gas suction system.
• Cleaning, maintenance and repair work may only be carried out once the engine is switched off and
secured to prevent it starting.
• Injection pipes and high-pressures lines must not be deformed.
• Any damaged injection pipe or high-pressure line must be replaced.
• Do not loosen any injection pipes for high-pressure fuel lines while the engine is running.
• Before carrying out checks to the running engine, always perform a visual check of all high-pressure
components. Suitable protective clothing (e.g. protective goggles) should be worn while doing this.
Leaks indicate potential sources of danger for workshop personnel.
• In the event of leaks to the high-pressure fuel system, always remain out of range of any possible fuel
spray to avoid serious injury.
• Even when no leaks to the high-pressure fuel system can be detected, workshop personnel should
avoid the immediate danger area and wear suitable protective clothing (such as protective goggles)
when carrying out checks to the running engine and during the first test run.
• Smoking is forbidden while carrying out work to the fuel system.
• Do not work in the proximity of sparks or naked flames.
• Never disconnect an injector while the engine is running.
