Clean up spilled fluids. Service the machine on a firm, level surface. Install guards and shields after you service the machine. Close all access doors and install all panels after servicing the machine. Do not attempt to clean, lubricate, clear obstructions, or make adjustments to the machine while it is in motion or while the engine is running. Always make sure that working area is clear of tools, parts, other persons and pets before you start operating the machine. Unsupported hydraulic cylinders can lose pressure and drop the equipment, causing a crushing hazard. Do not leave equipment in a raised position while parked or during service, unless the equipment is securely supported. Jack or lift the machine only at jack or lift points indicated in this manual. Incorrect towing procedures can cause accidents. When you tow a disabled machine follow the procedure in this manual. Use only rigid tow bars. Stop the engine, remove the key, and relieve pressure before you connect or disconnect fluid lines. Stop the engine and remove the key before you connect or disconnect electrical connections. Scalding can result from incorrect removal of coolant caps. Cooling systems operate under pressure. Hot coolant can spray out if you remove a cap while the system is hot. Allow the system to cool before you remove the cap. When you remove the cap, turn it slowly to allow pressure to escape before you completely remove the cap. Replace damaged or worn tubes, hoses, electrical wiring, etc. The engine, transmission, exhaust components, and hydraulic lines may become hot during operation. Take care when you service such components. Allow surfaces to cool before you handle or disconnect hot components. Wear protective equipment when appropriate. When welding, follow the instructions in the manual. Always disconnect the battery before you weld on the machine. Always wash your hands after you handle battery components. General battery safety Always wear eye protection when you work with batteries. Do not create sparks or have open flame near a battery. Ventilate the area when you charge a battery or use a battery in an enclosed area. Disconnect the negative (-) terminal first and reconnect the negative (-) terminal last. When you weld on the machine, disconnect both terminals of the battery. Do not weld, grind, or smoke near a battery. When you use auxiliary batteries or connect jumper cables to start the engine, use the procedure shown in the operator’s manual. Do not short across terminals. Follow the manufacturer’s instructions when you store and handle batteries. 48048570 27/04/2017 5 INTRODUCTION Battery post, terminals, and related accessories contain lead and lead compounds. Wash hands after handling. This is a California Proposition 65 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. Keep out of reach of children and other unauthorized persons. Air-conditioning system The air-conditioning system is under high pressure. Do not disconnect any lines. The release of high pressure can cause serious injury. The air-conditioning system contains gases that are harmful to the environment when released into the atmosphere. Do not attempt to service or repair the system. Only trained service technicians can service, repair, or recharge the air-conditioning system. Personal Protective Equipment (PPE) Wear Personal Protective Equipment (PPE) such as hard hat, eye protection, heavy gloves, hearing protection, protective clothing, etc. Do Not Operate tag Before you start servicing the machine, attach a ‘Do Not Operate’ warning tag to the machine in an area that will be visible. 48048570 27/04/2017 6 INTRODUCTION Safety rules - Ecology and the environment 2050M NA 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. 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-conditioning 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. Improper disposal of batteries can contaminate the soil, groundwater, and waterways. CASE CONSTRUCTION strongly recommends that you return all used batteries to a CASE CONSTRUCTION dealer, who will dispose of the used batteries or recycle the used batteries properly. In some countries, this is a legal requirement. Mandatory battery recycling NOTE: The following requirements are mandatory in Brazil. Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead, CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any batteries. Do not dispose of batteries in your household garbage. Points of sale are obliged to: • Accept the return of your used batteries • Store the returned batteries in a suitable location • Send the returned batteries to the battery manufacturer for recycling 48048570 27/04/2017 7 INTRODUCTION Safety rules - Do not operate tag 2050M NA WARNING Maintenance hazard!

Too much torque on a hydraulic connection can lead to leakage or failure. NOTICE: There are several different kinds of parallel thread ports, including those using metric threads, inch threads, and British Standard Pipe Parallel (BSPP) threads. None of these port systems are interchangeable, and using the wrong connector in a port will not provide an adequate seal, even if it is possible to install the part. NOTE: Hand install and hand tighten all connections before using tools to set the torque. This will reduce the possibility of thread damage.
