Introduction and Safety in the Workshop INTRODUCTION The purpose of this manual is to assist Dealers and Distributors in the efficient repair and maintenance of Massey Ferguson farm machinery. Carrying out the procedures as detailed, together with the use of special tools where appropriate, will enable the operations to be completed within the time stated in the Repair Time Schedule. To assist with locating information, each section of the manual is preceded by a contents page listing the operations. Each instruction within an operation has a sequence number, and to complete the operation in the minimum time it is essential that these instructions are performed in numerical sequence commencing at 1, unless otherwise stated. When applicable, these sequence numbers identify the components in the appropriate illustration. Where an operation requires the use of a special tool, the tool number is quoted under the operation heading and is repeated in, or following, the instruction involving its use. Indexing For convenience the manual is divided into sections and parts, each page bearing a section and part number. The sections are subdivided into numbered operations. Example: 1-7 A would be Operation 1 in Section 7, Part A. This simplifies cross referencing and enables the subject to be found easily. Definition of Terms The operation descriptions generally used throughout the schedules may be defined as follows: Removal and Refitment- Remove and refit an original part or assembly, or a new part or assembly which does not involve additional operations or time. Install - Install a part or component not previously fitted e.g., accessories. Overhaul-Remove a part or assembly, dismantle, inspect and recondition, re-assemble, and re-install making all necessary adjustments. Dis-assembly and Rs-assembly The terms 'Dis-assembly' and 'Re-assembly' indicate the orderly taking apart of an assembly into individual parts and rebuilding it into the original assembly. Adjust - Make the necessary adjustments to restore specified setting or performance. Check - Ascertain if a setting or condition is within the limits of acceptability, either as defined in the manufacturer's specifications or, where a dimension is not specified, in the judgement of the mechanic. The checking of fixings, e.g. nuts and bolts, includes tightening to the specified torque figures listed in this Manual. Servicing -All technical work undertaken to maintain the machine in working order. 1A-2 Special Tools Where the use of a special tool is specified in an operation the tool number will be shown under the operation heading and also following the instruction requiring its use. The use of the special tools mentioned in the text contributes to a safe, efficient and profitable repair. Some operations are impracticable without their use, for example, the refitment of the differential unit. Distributors and Dealers are therefore urged to check their tools against the list provided. Where necessary, tools may be ordered from: AGCO Limited. Product Reliability, Banner Lane, Coventry. CV4 9FG (Phone 44 (0) 1203 694400) (Fax 44 (0) 1203 852318). For further details, refer to the special tool catalogue for this range of tractors, Publication No. 1856 550 M5, or Section 14 of this manual. Repairs and Replacements When service parts are required it is essential that only genuine Massey Ferguson replacements are used. Attention is particularly drawn to the following points concerning repairs and the fitting of replacement parts and accessories: Safety features embodied in the tractor may be impaired if other than genuine parts are fitted. In certain territories, legislation prohibits the fitting of parts not to the tractor manufacturer's specification. Torque wrench setting figures given in the Workshop Manual must be strictly adhered to. Locking devices where specified must be fitted. If the efficiency of a locking device is impaired during removal it must be renewed. The tractor warranty may be invalidated by the fitting of other than genuine Massey Ferguson parts. All Massey Ferguson replacements have the full backing of the manufacturer's warranty. Massey Ferguson Distributors and Dealers are obliged to supply only genuine service parts. Repair of the Tractor Follow these important points: CLEAN THE TRACTOR AND DIAGNOSE THE FAULT BEFORE DIS-ASSEMBLY. If possible, make a complete diagnosis to determine the extent of the repair required. Take precautions, as necessary, to prevent dirt or other foreign material entering the hydraulic, fuel or air systems. DO NOT MIX PARTS. Make particular note of special parts which should not be interchanged. DURING DIS-ASSEMBLY, CLEAN PARTS THOROUGHLY AND INSPECT THEM FOR WEAR, DAMAGE, ETC. LABEL PARTS. PROTECT PRECISION OR MACHINED SURFACES. 200 Series - Issue 4

Introduction and Safety in the Workshop Amendments Under normal conditions revised pages are issued carrying the same number as the existing pages requiring amendment. The new pages are inserted in place of the existing ones. The old pages should then be destroyed. The issue number is printed on the bottom of each page, e.g. Issue 4, 2 or 3 etc. In some cases additional pages or completely new sections may be issued. These pages are to be inserted immediately following the page carrying the next lowest page number, or section number as appropriate. Where new pages are required to be positioned between existing pages, the new page numbers will contain a suffix letter - example: New page number 7A-16a. This page is inserted after existing page number 7 A-16 and before page number 7A-17. Correspondingly a further new page numbered 7A-16b would be positioned after 7A-16a but before 7A-17.

Introduction and Safety in the Workshop SAFETY ALERT SYMBOL AND TERMS This safety alert symbol means ATIENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! The safety alert symbol identifies important safety messages on machines, safety signs, in manuals, or elsewhere. When you see this symbol, be alert to the possibility of personal injury or death. Follow the instructions in the safety message. Why is SAFETY important to you? * ACCIDENTS DISABLE AND KILL * * ACCIDENTS ARE COSTLY * * ACCIDENTS CAN BE AVOIDED * SAFETY in the WORKSHOP This safety section of your Workshop Service manual is intended to point out some of the basic safety situations which may be encountered during the normal repair operations of the tractor, and to suggest possible ways of dealing with these situations. Additional precautions may be necessary, depending on the type of repair and the conditions at the work site or in the workshop. Massey Ferguson has no direct control over the repair procedures, operation, inspection, lubrication or general maintenance. Therefore it is YOUR responsibility to use good safety practices in these areas. SAFETY - A WORD to the MECHANIC It is your responsibility to read and understand this safety section before carrying out repairs on Massey Ferguson equipment. Remember that YOU are the key to safety.

/.---- Introduction and Safety in the Workshop SAFETY DECALS • WARNING: DO NOT remove or obscure Danger, Warning or Instruction Decals. Replace any Danger, Warning, Caution or Instruction Decals that are not readable, damaged or are missing. GENERAL Practically all service work involves the need to drive a tractor. The Operator Instruction Book, supplied with each tractor or implement, contains detailed safety precautions relating to driving, operating and servicing. These precautions are as applicable to the service mechanic as they are to the operator, and should be read, understood and practised by all personnel. Prior to undertaking any maintenance, repair, overhaul, dismantling or re-assembly operations, whether within a workshop facility or out 'in the field', consideration should be given to factors that may have an effect upon Safety, not only upon the mechanic carrying out the work, but also upon bystanders. • DO NOT allow children or bystanders around or on the machine while it is being adjusted, serviced, repaired or operated. PERSONAL CONSIDERATIONS Clothing • The wrong clothes or carelessness in dress can cause accidents. Check to see that you are suitably clothed. DO NOT wear loose clothing or long hair around equipment. Some jobs require special protective equipment Eye Protection • The smallest eye injury may cause loss of vision. Injury can be avoided by wearing the proper eye protection when engaged in chiselling, grinding, discing, sanding, welding, painting etc. • Wear safety goggles or safety glasses appropriate to the job in hand. Breathing Protection • Fumes, dust and paint spray are unpleasant and harmful. These can be avoided by wearing respiratory protection. Hearing Protection • Loud noise may damage your hearing and the greater the exposure the worse the damage. If you think the noise is excessive, wear ear protection. Hand Protection 200 Series - Issue 4 • It is advisable to use a protective barrier cream before work to prevent irritation and skin contamination. After work clean your hands in soap and water. Solvents such as white spirit, paraffin, etc., may harm the skin. • Wear gloves when ever possible to protect your hands. DO NOT wear rings or wrist watches when working on machinery, as they could catch on moving parts and cause serious injury. Foot Protection • Substantial or protective footwear with reinforced toe-caps (safety shoes) will protect your feet from falling objects. Additionally, oil-resistant sales will help to avoid slipping. Special Clothing • For certain work it may be necessary to wear flame or acid-resistant clothing. EQUIPMENT CONSIDERATIONS Machine Guards • Before using any machine, check to ensure that the machine guards are in position and serviceable. These guards not only prevent parts of the body or clothing coming in contact with the moving parts of the machine, but also ward off objects that might fly off the machine and cause injury. Ensure that missing guards are replaced. Lifting Appliances • Always ensure that lifting equipment, such as chains, slings, lifting brackets, hooks and eyes are thoroughly checked before use. If in doubt, select stronger equipment than is necessary. • Never stand under a suspended load or raised implement. • Avoid Injury through incorrect handling of components. Make sure you are capable of lifting the object. If in doubt get help. Jacking • Select a jack strong enough to carry the load. • Stabilise the tractor and chock the wheels. • Put support stands under the tractor. Lower the jack and let the tractor rest on the stands. • DO NOT go under a tractor supported by a chain hoist or jack. 1A-5

Introduction and Safety in the Workshop Compressed Air • The pressure from a compressed air line is often as high as 7 bar (100 Ibf/in 2 ). It is perfectly safe if used correctly. Any misuse may cause injury. • Never use compressed air to blow dust, filings, dirt etc., away from your work area unless the correct type of nozzle is fitted and eye protection is used. • Compressed air is not a cleaning agent, it will only move dust, etc., from one place to another. Look around before using an air hose as bystanders may get grit into their eyes, ears or skin. • Used approved air guns, wear safety goggles, and use proper shielding to protect others in the work area. • Never point an air nozzle at a persons body. Hand Tools • Many cuts, abrasions and injuries are caused by defective tools. Never use the wrong tool forthe job, as this generally leads either to some injury, or to a poor job. • Never use: - A hammer with a loose head or split handle. - Spanners or wrenches with splayed or worn jaws. - Spanners or files as hammers; or drills, clevis pins or bolts as punches. • Grind off mushroom heads from chisels. The sharp edges can tear your skin if the tool slips. And, when the tool is struck, chips could break off and fly into your eyes. • Keep a handle on every file to prevent the tang from piercing your palm or wrist if the file should slip or catch. • For removing or replacing hardened pins use a copper or brass drift rather than a hammer. • For dismantling, overhauling and assembly of major components, always use Special Service Tools recommended. These will reduce the work effort, labour time and repair cost. • Always keep tools clean and in good working order. Electricity • Electricity has become so familiar in day to day usage, that its potentially dangerous properties are often overlooked. Misuse of electrical equipment can endanger life. • Before using any electrical equipment - particularly portable appliances - make a visual check to make sure that the cable is not worn or frayed and that the plugs, sockets, etc., are intact; make sure you know where the nearest isolating switch is located. Always use an earthed (grounded) 3 pin electrical cord. lA--6 GENERAL CONSIDERATIONS Solvents • Use only cleaning fluids and solvents that are known to be safe. Certain types of fluids can cause damage to components such as seals, etc., and can cause skin irritation. Solvent labels should be checked that they are suitable not only for the cleaning of components and individual parts, but also that they DO NOT affect the personal safety of the user. Housekeeping • Many injuries result from tripping or slipping over or on, objects or material left lying around by a careless worker. Prevent these accidents from occurring. If you notice a hazard, don't ignore it - remove it. • A clean, hazard-free place of work improves the surroundings and daily environment for everybody. • Keep work organised and clean. Wipe up spills of any kind to minimise the possibility of a fall. Keep tools and parts off the floor to further reduce the possibility of tripping and causing serious injury. Fire • Fire has no respect for persons or property. The destruction that fire can cause is not always fully realised. Everyone must be constantly on guard. - Extinguish matches, cigars, cigarettes, etc., before throwing them away. - Work cleanly, disposing of waste material into proper containers. - Locate the fire extinguishers and find out how to operate them. - DO NOT allow or use open flame near the fuel tank, fuel lines, battery, hydraulic hoses or component parts • When using a gas torch, always keep a fully charged fire extinguisher within reach. • In the event of fire: - DO NOT panic - warn those near and raise the alarm. First Aid • In the type of work that mechanics are engaged in, dirt, grease, fine dust, etc. all settle upon the skin and clothing. If a cut, abrasion or burn is disregarded it may be found that an infection has formed within a short time. What appears at first to be trivial could become painful and injurious. It only takes a few minutes to have a fresh cut dressed, but it will take longer if you neglect it. Make sure you know where the First Aid box is located and that it is kept fully stocked at all times. 200 Series - Issue 4
