- Page 9 INTRODUCTION Safety rules This warning symbol points out important messages involving personal safety. Carefully read the safety rules contained herein and follow advised precautions to avoid potential hazards and safeguarded your safety. In this manual you will find this symbol together with the following keywords. WARNING: It gives warning about improper repair operations and potential consequences affecting the service tech- nician’s personal safety.
- Page 10 INTRODUCTION Safety rules Generalities Carefully follow specified repair and maintenance procedures. • Do not wear rings, wrist watches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open jackets or shirts with open zips which could get caught in moving parts. Use approved safety clothing such as anti-slipping footwear, gloves, safety goggles, helmets, etc.
- Page 11 INTRODUCTION Electrical systems • If it is necessary to use auxiliary batteries, cables must be connected at both sides as follows. (+) to (+) and (-) to (-). Avoid short-circuiting the terminals. Gas released from batteries is highly flammable. During charging, leave the battery compartment uncovered to improve ventilation.
- Page 12 INTRODUCTION Safety rules Health and safety precautions Many of the procedures associated with vehicle maintenance and repair involve physical hazards or other risks to health. This section lists, alphabetically, some of these hazardous operations and the materials and equipment asso- ciated with them.
- Page 13 INTRODUCTION Isocyanate (polyurethane) adhesives / sealers See resin based adhesives. Individuals suffering from asthma or respiratory allergies should not work with or near these materials as sensitivity reactions can occur. Any spraying should preferably be carried out in exhaust ventilated booths removing vapors and spray droplets form the breathing zone.
- Page 14 INTRODUCTION Do organise work practices and protective clothing to avoid soling of the skin and eyes, breathing vapors / aerosols / dusts / fumes, inadequate container labelling; fire and explosion hazards. Do wash before job breaks, before eating, smoking, drinking or using toilet facilities when handling chemical materials. Do keep work areas clean, uncluttered and free of spills.
- Page 15 INTRODUCTION Dusts Powder, dusts or clouds may be irritant, harmful or toxic. Avoid breathing dusts from powdery chemical materials or those arising from dry abrasion operations. Wear respiratory protection if ventilation is inadequate. Electric shocks Electric shocks can result from the use of the faulty electrical equipment or from the misuse of equipment even in good condition.
- Page 16 INTRODUCTION Observe strict fire safety when storing and handling flammable materials or solvents, particularly near electrical equip- ment or welding processes. Ensure before using electrical or welding equipment but that there is no fire hazard present. Have suitable fire extinguisher available when using welding or heating equipment. First aid Apart from meeting any legal requirements its i desirable for someone in the workshop to be trained in first aid proce- dures.
- Page 17 INTRODUCTION Ensure there is adequate ventilation when handling and using gasoline. Great care must be taken to avoid the serious consequences of inhalation in the event of vapor build up arising from spillages in confined spaces. Special precautions apply to cleaning and maintenance operations on gasoline storage tanks. Gasoline should not be used as a cleaning agent.
- Page 18 INTRODUCTION Do not use damaged or defective tools or equipment, particularly high speed equipment such as grinding wheels. A damaged grinding wheel can disintegrate without warning and cause serious injury. Wear suitable eye protection when using grinding, chiselling or sand blasting equipment. Wear a suitable breathing mask when using sand blasting equipment, working with asbestos based materials or using spraying equipment.
- Page 19 INTRODUCTION Two pack Can also contain harmful and toxic unreacted resins and resin hardening agents. The manufacturers instructions should be followed and the on resin based adhesives, isocyanate containing adhesives and foams should be con- sulted. Spraying should preferably be carried out in exhausted ventilated booths removing vapor and spray mists from the breathing zone.
- Page 20 INTRODUCTION Brief exposure to high concentrations of vapors or mists will cause eye and throat irritation, drowsiness, dizziness, headaches and in the worst circumstances, unconsciousness. Repeated or prolonged exposures to excessive but lower concentrations of vapors or mists, for which theremight not be adequatewarning indications, can cause more serious toxic or harmful effects.
- Page 21 INTRODUCTION particularly in cases where the general ventilation is poor, or where considerable welding work is anticipated. In extreme cases where adequate ventilation cannot be provided, supplied air respirators may be necessary. Gas welding Oxy-acetylene torches may be used for welding and cutting and special care must be taken to prevent leakage of these gases, with consequent risk of fire and explosion.

- Page 36 Engine - Engine and crankcase NDIL14TR00926FA Fuel system The diesel fuel system consists of fuel tank, lift pump, fuel filters, mico rotary type fuel injection pump, fuel injectors, and interconnecting tubes and lines. The fuel injection pump is pressure fed from the lift pump. Fuel flows from the fuel tank to the sediment separator (incorporated in lift pump), through the lift pump, then through the primary fuel filter and then to secondary fuel filter.
- Page 37 Engine - Engine and crankcase Fuel Filters Spin-on type fuel filters situated to the right-hand side of the engine, receives fuel from lift pump. From the filter head the fuel is diverted down through the filter element and into the base chamber. The filtered fuel then flows up the centre tube of the element to the filter head outlet and into the injection pump.
