CODE 1-5302-620 MODEL N° 50902 DATE OF ISSUE 08-03 REVISION 00 II SAFETY AND WARNING DECALS - SAFETY INSTRUCTIONS Failure to comply with the instructions could result in damage to persons and property Failure to comply with the instructions could lead to technical damage to the machine and/or system SAFETY AND W ARNING DECALS SAFETY INSTRUCTIONS DANGER CAUTION • Ruggerini Engines are built to supply their performances in a safe and long-lasting way. To obtain these results, it is essential for users to comply with the servicing instructions given in the relative manual along with the safety recommendations listed below. • The engine has been made according to a machine manufacturer's specifications and all actions required to meet the essential safety and health safeguarding requisites have been taken, as prescribed by the current laws in merit. All uses of the engine beyond those specifically established cannot therefore be considered as conforming to the use defined by Ruggerini which thus declines all liability for any accidents deriving from such operations. • The following indications are dedicated to the user of the machine in order to reduce or eliminate risks concerning engine operation in particular, along with the relative routine maintenance work. • The user must read these instructions carefully and become familiar with the operations described. Failure to do this could lead to serious danger for his personal safety and health and that of any persons who may be in the vicinity of the machine. • The engine may only be used or assembled on a machine by technicians who are adequately trained about its operation and the deriving dangers. This condition is also essential when it comes to routine and, above all, extraordinary maintenance operations which, in the latter case, must only be carried out by persons specifically trained by Ruggerini and who work in compliance with the existing documentation. • Variations to the functional parameters of the engine, adjustments to the fuel flow rate and rotation speed, removal of seals, demounting and refitting of parts not described in the operation and maintenance manual by unauthorized personnel shall relieve Ruggerini from all and every liability for deriving accidents or for failure to comply with the laws in merit. • On starting, make sure that the engine is as horizontal as possible, unless the machine specifications differ. In the case of manual start-ups, make sure that the relative actions can take place without the risk of hitting walls or dangerous objects, also considering the movements made by the operator. Pull-starting with a free cord (thus excluding self- winding starting only), is not permitted even in an emergency. • Make sure that the machine is stable to prevent the risk of overturning. • Become familiar with how to adjust the rotation speed and stop the engine. • Never start the engine in a closed place or where there is insufficient ventilation. Combustion creates carbon monoxide, an odourless and highly poisonous gas. Lengthy stays in places where the engine freely exhausts this gas can lead to unconsciousness and death.

9 COMPILER TECO/ATI ENDORSED DATE 01.08.2003 REG. CODE 1-5302-620 MODEL N° 50902 DATE OF ISSUE 08-03 REVISION 00 II SAFETY AND WARNING DECALS - SAFETY INSTRUCTIONS • The engine must not operate in places containing inflammable materials, in explosive atmospheres, where there is dust that can easily catch fire unles specific, adequate and clearly indicated precautions have been taken and have been certified for the machine. • To prevent fire hazards, always keep the machine at least one meter from buildings or from other machinery. • Children and animals must be kept at a due distance from operating machines in order to prevent hazards deriving from their operation. • Fuel is inflammable. The tank must only be filled when the engine is off. Thoroughly dry any spilt fuel and move the fuel container away along with any rags soaked in fuel or oil. Make sure that no soundproofing panels made of porous material are soaked in fuel or oil. Make sure that the ground or floor on which the machine is standing has not soaked up any fuel or oil. • Fully tighten the tank plug each time after refuelling. Do not fill the tank right to the top but leave an adequate space for the fuel to expand. • Fuel vapour is highly toxic. Only refuel outdoors or in a well ventilated place. • Do not smoke or use naked flames when refuelling. • The engine must be started in compliance with the specific instructions in the operation manual of the engine and/or machine itself. Do not use auxiliary starting aids that were not installed on the original machine (e.g. Startpilot’). • Before starting, remove any tools that were used to service the engine and/or machine. Make sure that all guards have been refitted. • During operation, the surface of the engine can become dangerously hot. Avoid touching the exhaust system in particular. • Before proceeding with any operation on the engine, stop it and allow it to cool. Never carry out any operation whilst the engine is running. • The coolant fluid circuit is under pressure. Never carry out any inspections until the engine has cooled and even in this case, only open the radiator plug or expansion chamber with the utmost caution, wearing protective garments and goggles. If there is an electric fan, do not approach the engine whilst it is still hot as the fan could also start operating when the engine is at a standstill. Only clean the coolant system when the engine is at a standstill. • When cleaning the oil-cooled air filter, make sure that the old oil is disposed of in the correct way in order to safeguard the environment. The spongy filtering material in oil-cooled air filters must not be soaked in oil. The reservoir of the separator pre-filter must not be filled with oil. • The oil must be drained whilst the engine is hot (oil T ~ 80°C). Particular care is required to prevent burns. Do not allow the oil to come into contact with the skin. • Make sure that the drained oil, the oil filter and the oil it contains are disposed of in the correct way in order to safeguard the environment. • Pay attention to the temperature of the oil filter when the filter itself is replaced. • Only check, top up and change the coolant fluid when the engine is off and cold. Take care to prevent fluids containing nitrites from being mixed with others that do not contain these substances since "Nitrosamine", dangerous for the health, can form. The coolant fluid is polluting and must therefore be disposed of in the correct way to safeguard the environment. • During operations that involve access to moving parts of the engine and/or removal of rotating guards, disconnect and insulate the positive wire of the battery to prevent accidental short-circuits and to stop the starter motor from being energized. • Only check belt tension when the engine is off. • Only use the eyebolts installed by Ruggerini to move the engine. These lifting points are not suitable for the entire machine; in this case, the eyebolts installed by the manufacturer should be used. Downloaded from www.Manualslib.com manuals search engine
