Safety rules - Ecology and the environment
CX36B
Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the
treatment of some of the substances that advanced technology requires, sound judgment should govern the use and
disposal of products of a chemical and petrochemical nature.
NOTE: The following are recommendations that may be of assistance:
• Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this
legislation.
• Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze, cleaning
agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use, and
dispose of these substances.
Helpful hints
• Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems
may cause considerable spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances
that may be harmful to your health.
• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
• Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid,
etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of
the fluids in a proper way that complies with all local legislation and available resources.
• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-condi-
tioning specialist or use a special extractor to recharge the system properly.
• Repair any leaks or defects in the engine cooling system or hydraulic system immediately.
• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
• Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils,
coolant, etc.
Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful effect on the environment
if the batteries are not properly recycled after use. CASE CONSTRUCTION strongly recommends that equipment
owners return all used batteries to a [Brand] dealer, who will dispose of the used batteries or recycle the used batteries
properly. In some countries, this is a legal requirement.

Safety rules Personal Safety
CX36B
Most accidents involving machine operation and maintenance can be avoided by following basic safety rules and
precautions. Read and understand all the safety messages in this manual and the safety signs on the machine before
you operate or service the machine. See your dealer if you have any questions.
READ THIS MANUAL COMPLETELY and make sure you understand the controls. All equipment has a limit. Make
sure you understand the speed, brakes, steering, stability, and load characteristics of the machine before you start to
operate this machine.
DO NOT remove this manual from the machine.
The safety information given in this manual does not replace safety codes, insurance needs, federal, state, or local
laws. Make sure that your machine has the correct equipment according to these rules or laws.
Additional safety messages are used in the text of the manual to show specific safety hazards.
NOTICE: The safety messages in this chapter point out conditions which can happen during the normal operation
and maintenance of your machine. These safety messages also give possible ways of dealing with these conditions.

Basic instructions - Shop and assembly
CX36B
Shimming
For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a microm-
eter, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or
the rated value shown on each shim.
Rotating shaft seals
For correct rotating shaft seal installation, proceed as follows:
1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.
2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.
3. Position the sealing lip facing the fluid.
NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that
they will move the fluid towards the inner side of the seal.
4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip
and the dust lip on double lip seals with grease.
5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a
hammer or mallet.
6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that
the seal makes contact with the thrust element, if required.
7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.
O-ring seals
Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and
twisting, which would jeopardize sealing efficiency.
Sealing compounds
Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing
compound, prepare the surfaces as directed by the product container.
Spare parts
Only use CNH Original Parts or CASE CONSTRUCTION Original Parts.
Only genuine spare parts guarantee the same quality, duration, and safety as original parts, as they are the same
parts that are assembled during standard production. Only CNH Original Parts or CASE CONSTRUCTION Original
Parts can offer this guarantee.
When ordering spare parts, always provide the following information:
• Machine model (commercial name) and Product Identification Number (PIN)
• Part number of the ordered part, which can be found in the parts catalog

8. INTRODUCTION
Protecting the electronic and/or electrical systems during charging and welding
To avoid damage to the electronic and/or electrical systems, always observe the following practices:
1. Never make or break any of the charging circuit connections when the engine is running, including the battery
connections.
2. Never short any of the charging components to ground.
3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine
attachment.
• Position the welder ground clamp as close to the welding area as possible.
• If you weld in close proximity to a computer module, then you should remove the module from the machine.
• Never allow welding cables to lie on, near, or across any electrical wiring or electronic component while you
weld.
4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery
charger.
NOTICE: If you must weld on the unit, you must disconnect the battery ground cable from the machine battery.
The electronic monitoring system and charging system will be damaged if this is not done.
5. Remove the battery ground cable. Reconnect the cable when you complete welding.
WARNING
Battery acid causes burns. Batteries contain sulfuric acid.
Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush
with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large
quantities of water or milk. Do not induce vomiting. Seek medical attention immediately.
Failure to comply could result in death or serious injury.
