INTRODUCTION
Note to the Owner WARNINGS FOR AIR CONDITIONING SYSTEM
REPAIR OPERATIONS
Farmall® 100N With cab [ZGLL03072 - ]
Farmall® 110V With cab [ZGLL03383 - ]
Starting the system at low temperatures can damage the compressor. Only operate the air conditioner when the
engine is hot and the temperature inside the cab is at least 20 °C (68.00 °F).
When disconnecting the hoses, close the ends with plastic caps to prevent foreign matter and humidity from getting
inside the hoses.
Handle the thermostatic sensor carefully to avoid damage that may prevent efficient system operation.
Always use two spanners to unscrew the hose fittings to avoid twisting the fitting.
Do not use any type of engine oil to lubricate the compressor and the system.
Never leave the compressor oil container open, always make sure that it is tightly closed. If left exposed the oil will
absorb humidity from the air and may, subsequently, damage the system.
Do not transfer compressor oil from the original container to another container.
Do not introduce any additives to the compressor oil. Any additional substances could contain elements which are
incompatible with the chemical base of the refrigerant and thus alter its characteristics.
Check that the thermostatic sensor is correctly inserted in the fins on the evaporator to ensure efficient system oper-
ation.

INTRODUCTION
Safety rules SAFETY REGULATIONS
TO PREVENT ACCIDENTS
Most accidents or injuries that occur in workshops are the result of non--observance of simple and fundamental safety
regulations.
For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED: by foreseeing possible causes and con-
sequently acting with the necessary caution and care.
Accidents may occur with all types of vehicle, regardless of how well it was designed and built.
A careful and judicious service technician is the best guarantee against accidents.
Precise observance of the most basic safety rule is normally sufficient to avoid many serious accidents.
DANGER: Never carry out any cleaning, lubrication or maintenance operations when the engine is running.
GENERAL
• Carefully follow specified repair and maintenance procedures.
• Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing,
scarves, open jackets or shirts with open zips that may remain entangled in moving parts.
It is advised to wear approved safety clothing, e.g: non--slip footwear, gloves, safety goggles, helmets, etc.
• Do not carry out repair operations with someone sitting in the driver’s seat, unless the person is a trained technician
who is assisting with the operation in question.
• Operate the vehicle and use the implements exclusively from the driver’s seat.
• Do not carry out operations on the vehicle with the engine running, unless specifically indicated.
• Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves,
etc.
• All repair and maintenance operations must be carried out using extreme care and attention.
• Service steps and platforms used in a workshop or in the field should be built in compliance with the safety rules in
force.
• Disconnect the batteries and label all controls to indicate that the vehicle is being serviced. Block the machine and
all equipment which should be raised.
• Do not check or fill fuel tanks, accumulator batteries, nor use starting liquid when smoking or near naked flames,
as these fluids are inflammable.
• Brakes are inoperative if manually released for repair or maintenance purposes.
In such cases, the machine should be kept constantly under control using blocks or similar devices.
• The fuel nozzle should always be in contact with the filling aperture. Maintain this position until filling operations
are completed in order to avoid possible sparks caused by the accumulation of static electricity.
• Only use specified towing points for towing the tractor, connect parts carefully.Make sure that all pins and/or locks
are secured in position before applying traction.
Never remain near the towing bars, cables or chains that are operating under load
• Transport vehicles that cannot be driven using a trailer or a low--loading platform trolley, if available.
• When loading or unloading the vehicle from the trailer (or other means of transport), select a flat area capable
of sustaining the trailer or truck wheels, firmly secure the tractor to the truck or trailer and lock the wheels in the
position.
• Electric heaters, battery--chargers and similar equipment must only be powered by auxiliary power supplies with
efficient ground insulation to avoid electrical shock hazards.
• Always use suitable hoisting or lifting devices when raising or moving heavy parts.
• Take extra care if bystanders are present.
• Never pour gasoline or diesel oil into open, wide and low containers.
• Never use gasoline, diesel oil or other inflammable liquids as cleaning agents. Use non-flammable non-toxic pro-
prietary solvents.
• Wear safety goggles with side guards when cleaning parts with compressed air.
• Limit the air pressure to a maximum of 2.1 bar (30.5 psi), according to local regulations.

INTRODUCTION
• Do not run the engine in confined spaces without suitable ventilation.
• Do not smoke, use naked flames, or cause sparks in the area when fuel filling or handling highly inflammable liquids.
• Never use naked flames for lighting when working on the machine or checking for leaks.
• All movements must be carried out carefully when working under, on or near the vehicle and wear protective equip-
ment: helmets, goggles and special footwear.
• When carrying out checks with the engine running, request the assistance of an operator in the driver’s seat. The
operator must maintain visual contact with the service technician at all times.
• If operating outside the workshop, position the vehicle on a flat surface and lock in position. If working on a slope,
lock the vehicle in position and move to a flat area as soon as is safely possible.
• Damaged or bent chains or cables are unreliable. Do not use them for lifting or towing.
Always use suitable protective gloves when handling chains or cables.
• Chains should always be safely secured. Ensure that fastening device is strong enough to hold the load foreseen.
No persons should stop near the fastening point, trailing chains or cables.
• Maintenance and repair operations must be carried out in a CLEAN and DRY area, eliminate any water or oil spillage
immediately.
• Do not create piles of oil or grease--soaked rags as they represent a serious fire hazard; store them in a closed
metal container.
Before starting the vehicle or implements, make sure that the driver’s seat is locked in position and always check
that the area is free of persons or obstacles.
• Empty pockets of all objects that may fall unobserved into the vehicle parts when disassembled.
• In the presence of protruding metal parts, use protective goggles or goggles with side guards, helmets, special
footwear and gloves.
• Handle all parts carefully, do not put your hands or fingers between moving parts, wear suitable safety clothing --
safety goggles, gloves and shoes.
WELDING OPERATIONS
• When welding, use protective safety devices: tinted safety goggles, helmets, special overalls, gloves and footwear.
All persons present in the area where welding is taking place must wear tinted goggles.
NEVER LOOK AT THE WELDING ARC IF YOUR EYES ARE NOT SUITABLY PROTECTED.
• Where possible, remove the part or tool that requires arc welding from the tractor.
• Disconnect both battery leads. Isolate the cable ends to avoid contact with each other and the tractor.
• Position the welder ground clamp as near as possible to the area where welding is taking place.
• Remove the electronic control units located on the tractor if welding is to be carried out near these control units.
• Never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding is
in progress.
• Metal cables tend to fray with repeated use. Always use suitable protective devices (gloves, goggles, etc.) when
handling cables.
START UP
• Never start the engine in confined spaces that are not equipped with adequate ventilation for exhaust gas extraction.
• Never place the head, body, limbs, feet, hands or fingers near fans or rotating belts.
ENGINE
• Always loosen the radiator cap slowly before removing it to allow any remaining pressure in the system to be dis-
charged. Coolant should be topped up only when the engine is stopped or idle if hot.
• Never fill up with fuel when the engine is running, especially if hot, in order to prevent the outbreak of fire as a result
of fuel spillage
• Never check or adjust fan belt tension when the engine is running.
Never adjust the fuel injection pump when the vehicle is moving.

INTRODUCTION
• Never lubricate the vehicle when the engine is running.
ELECTRICAL SYSTEMS
• If it is necessary to use auxiliary batteries, remember that both ends of the cables must be connected as follows:
(+) with (+) and (-) with (-).
• Avoid short-circuiting the terminals. GAS RELEASED FROM BATTERIES IS HIGHLY INFLAMMABLE.
• During charging, leave the battery compartment uncovered to improve ventilation.
• Never check the battery charge using ”jumpers” (metal objects placed on the terminals).
• Avoid sparks or flames near the battery zone to prevent explosion hazards.
• Before servicing operations, check for fuel or current leaks. Eliminate any eventual leaks before starting work.
• Never charge batteries in confined spaces. Make sure that there is adequate ventilation in order to prevent acci-
dental explosion hazards as a result of the accumulation of gases released during charging operations.
• Always disconnect the battery before performing any kind of servicing on the electrical system.
HYDRAULIC SYSTEMS
• Some fluid slowly coming out from a very small port can be almost invisible and be strong enough to penetrate the
skin. Check for leaks using a piece of cardboard, NEVER USE HANDS.
• If any liquid penetrates skin tissue, call for medical aid immediately
• Serious skin infections may result if medical attention is not given.
• Use the specific tools when checking pressure values on the hydraulic system.
WHEELS AND TYRES
• Check that the tyres are correctly inflated at the pressure specified by the manufacturer.
Periodically check possible damages to the rims and tyres.
• Stand away from (at the side of) the tire when checking inflation pressure.
• Only check pressure when the vehicle is unloaded and the tires are cold, to avoid incorrect readings as a result of
over--pressure.
• Do not re--use parts of recovered wheels as incorrect welding or brazing may heat the material, causing it to weaken
and eventually damage or break the wheel.
• Never cut, nor weld a rim with the inflated tyre assembled.
• When removing the wheels, lock both the front and rear vehicle wheels.
• Always position support stands when raising the vehicle, in order to conform to current safety regulations.
• Deflate the tyre before removing any object caught into the tyre tread.
• Never inflate tires using inflammable gases; this could cause an explosion and put operator safety at risk.
REMOVAL AND RE-FITTING
• Lift and handle all heavy parts using suitable lifting equipment and make sure that all slings and hooks are correctly
secured.
• Handle all parts carefully during lifting operations, keep an eye on the personnel working near the load to be lifted.
Never insert hands or fingers between parts, always wear approved accident prevention clothing (goggles, gloves
and work boots).
• Avoid twisting chains or metal cables and always wear safety gloves when handling cables or chains.
