To avoid burns, do not touch hot components, e.g. the muffl er before they have cooled suffi ciently. Avoid getting fuel or oil on your skin or in your mouth. Use a barrier cream on your hands. This reduces the risk of infection and makes dirt easier to wash away. Long term contact with engine oil can represent a health hazard. Never start the engine indoors. Exhaust fumes are poi- sonous! They contain carbon monoxide, an odourless, poisonous and highly dangerous gas. Wipe up oil spills from the fl oor immediately to avoid slipping. Do not use tools that are worn or fi t badly, for example on nuts and bolts. + Always work on a clean bench. + Always work logically to ensure all parts are fi tted cor- rectly and that nuts and bolts are tightened. + Use the special tools where recommended to be able to carry out the work correctly and effi ciently. Fire risk Handle fuel with respect as it is extremely infl ammable. Never refuel while the engine is running. Do not smoke and ensure there are no open fl ames or sparks in the vicinity. Never start the engine if the machine is leaking fuel or if there has been a spillage when refuelling. Allow the remaining fuel to evaporate fi rst. Make sure there is a working fi re extinguisher close at hand. Do not try to extinguish a petrol fi re with water. Poisonous fumes When using cleaning agents read the instructions carefully. Ensure there is good ventilation when handling petrol and other volatile fl uids. The engine’s exhaust fumes are poisonous. Test run the engine outdoors. Special tools Some of the work described in this workshop manual re- quires special tools. In each section where this is necessary there is a picture of the tool and an order number. We recommend the use of special tools in order to avoid ex- pensive damage to parts in question and personal injury and to provide an effi cient repair procedure. Contact faces and gaskets Ensure all surfaces are clean and free from gasket residue, etc. When cleaning use a tool that will not damage the contact face. Any scratches or unevenness should be removed using a fl at fi ne cut fi le. Sealing rings Always replace a sealing ring that has been dismantled. The sensitive sealing lip can easily be damaged resulting in inferior sealing capacity. Surfaces which the seal shall seal against must also be completely undamaged. Lubricate the sealing lip with grease before it is fi tted and ensure that it is not damaged e.g. by shoulders and splines on a shaft. Use tape or a conical sleeve as protection. It is important that the sealing ring faces in the right direction for it to act as it is intended. The workshop used to carry out repairs must be equipped with safety devices in accordance with local directives. No one may carry out repairs without fi rst having read and understood the contents of this Workshop Manual. The boxes below can be found in appropriate parts of this manual. WARNING!
